Five compounds of mono para-hidroxy chalcon were synthesized (TC1, TC2, TC3, TC4, and TC5) and tested their cytotoxicity against HeLa cell and Raji cell. The difference in substituent of TC1 (R4 =H), TC2 (R4 = OCH3), and TC3 (R4 = F), showed the difference of their citotoxicity against HeLa cell. The citotoxicity of TC1 (LC50 = 16.08 µg/mL) ≈ TC3 (LC50 = 13.37 µg/mL), but the substituent difference of TC2 (LC50 = 147.43 µg/mL), decreasing it citotoxicity 10 times. Like wise their citotoxicity against Raji cell of TC1 (LC50 = 36.44 µg/mL) ≈ TC3 (LC50 = 30.46 µg/mL), but the substituent difference of TC2 (LC50 = 468.94 µg/mL), decreasing it citotoxicity activity 15 times. Nevertheless the strength of citotoxicity TC4 (LC50 = 98.74 µg/mL) and TC5 (LC50 = 110.97 µg/mL) against Raji cell are stronger than the citotoxicity of two of them against HeLa cell (LC50 of TC4 = none, LC50 of TC5 = 576.53 µg/mL).

ABSTRACT The anaerobic bacterium Dehalococcoides ethenogenes is the only known organism that can completely dechlorinate tetrachloroethene or trichloroethene (TCE) to ethene via dehalorespiration. One of two corrinoid-containing enzymes responsible for this pathway, TCE reductive dehalogenase (TCE-RDase) catalyzes the dechlorination of TCE to ethene. TCE-RDase dehalogenated 1,2-dichloroethane and 1,2-dibromoethane to ethene at rates of 7.5 and 30 μmol/min/mg, respectively, similar to the rates for TCE,cis-dichloroethene (DCE), and 1,1-DCE. A variety of other haloalkanes and haloalkenes containing three to five carbon atoms were dehalogenated at lower rates. The gene encoding TCE-RDase,tceA, was cloned and sequenced via an inverse PCR approach. Sequence comparisons of tceA to proteins in the public databases revealed weak sequence similarity confined to the C-terminal region, which contains the eight-iron ferredoxin cluster binding motif, (CXXCXXCXXXCP)2. Direct N-terminal sequencing of the mature enzyme indicated that the first 42 amino acids constitute a signal sequence containing the twin-arginine motif, RRXFXK, associated with the Sec-independent membrane translocation system. This information coupled with membrane localization studies indicated that TCE-RDase is located on the exterior of the cytoplasmic membrane. Like the case for the two other RDases that have been cloned and sequenced, a small open reading frame, tceB, is proposed to be involved with membrane association of TCE-RDase and is predicted to be cotranscribed with tceA.

The application of calcium peroxide (CaO2) activated with ferrous ion chelate sodium citrate （TCD）to stimulate the degradation of trichloroethylene (TCE) was investigated. The experimental results show that the removal efficiency of TCE increases first and then decreases with the increase of CaO2 and Na2S2O8 dosage; the chelation ratio of Fe(II)/TCD, too much or too little, will affect the removal efficiency of TCE; when the molar ratio of CaO2/ Fe(II)/ TCD/ TCE is 18/6/6/1, the removal efficiency of TCE is the highest, reaching 97.99% within 200Min. The results demonstrated that the technique of CaO2 activated with ferrous ion is a highly promising technique in in situ chemical oxidation (ISCO) remediation in TCE contaminated sites.

Abstract Abstract 227 It is well established that the use of a donor matched for 9–10/10 alleles at HLA-A,-B,-C,-DRB1,-DQB1 significantly improves overall survival (OS) after unrelated donor (UD) haematopoietic stem cell transplantation (HSCT). Whilst the matching status for HLA-DPB1 alleles has been shown to influence transplant complications (relapse and graft-versus-host disease (GVHD), its impact on survival has not been well defined. The current unmet need in clinical practice is an approach to stratify selection criteria when a clinician is confronted with the choice between several 10/10 or 9/10 matched unrelated donors. There is now considerable interest in exploring different types of matching criteria to define permissive HLA-DPB1 mismatches which may be associated with an improved outcome. We have previously shown that HLA-DPB1 permissiveness can be functionally defined by the characterization of shared T cell epitopes (TCE) recognized by alloreactive T cells. In this model, allelic HLA mismatches are classified as permissive if they do not involve TCE disparities, and as non-permissive if they do. Using this concept, we developed two overlapping algorithms of permissivity for allelic HLA-DPB1 mismatches, on the basis of 3 (TCE3) or 4 (TCE4) groups of DPB1 alleles encoding immunogenic TCE. Data from relatively small prospective studies has shown a worse outcome to be associated with non-permissive DPB1 TCE disparities. Here, we present outcomes in 9123 UD-HSCT pairs, collected through the International Histocompatibility Working Group (IHWG). The cohort was comprised of 5809 10/10 matched transplant pairs and 3314 9/10 matched pairs. Within the 10/10 and 9/10 matched pairs three groups of patients were identified: 1. Zero DPB1 mismatches (i.e. allele matched), 2. Permissive DPB1 mismatch, 3. Non-permissive DPB1 mismatch. The model was adjusted for disease severity, source of stem cells, conditioning regimen, use of T-cell depletion, patient/donor gender and patient age. In line with DPB1 allele frequencies in worldwide populations, the number of transplants scored as permissive was higher for TCE3 (4398/7270 [60.4%]) than for TCE4 (2577/7270 [35.4%]). Using the DPB1 permissive mismatch transplants as the reference group (either 10/10 or 9/10 matched), we showed that DPB1 allelic matches resulted in similar survivals to DPB1 permissive mismatches, both in the 10/10 (HR 0.96, p=0.498 for TCE3 and HR 0.99, p=0.85 for TCE4) and the 9/10 setting (HR 0.97, p=0.70 for TCE3 and HR 0.99, p=0.96 for TCE4). In contrast, survival was significantly worse in the presence of a non-permissive TCE3 or TCE4 mismatch, both in the 10/10 (HR 1.15, p=0.0005 for TCE3 and HR 1.13, p=0.0035 for TCE4) and in the 9/10 matched setting (HR 1.13, p=0.0140 for TCE3 and HR 1.11, p=0.0448 for TCE4). The survival detriment appeared to be due to a significantly increased non-relapse mortality (TCE3: 10/10 HR 1.27, p<0.001 and 9/10 HR 1.21, p=0.0001; TCE4: 10/10 HR 1.24, p<0.001 and 9/10 HR 1.13, p=0.0514), as well as an increase in grades II-IV acute GVHD (TCE3: 10/10 HR 1.17, p<0.001 and 9/10 HR 1.29, p<0.001; TCE4: 10/10 HR 1.12, p=0.0035 and 9/10 HR 1.19, p<0.0001). There was no significant difference in disease relapse between permissive and non-permissive mismatched pairs. Finally, using the 10/10 DPB1 permissive mismatched group as a reference, we found survival to be similar for 10/10 DPB1 non-permissive (HR 1.15) and 9/10 DPB1 permissive (HR 1.20) or DPB1 allele matched (HR 1.17) transplants. In conclusion, our results suggest that extending donor selection to include HLA-DPB1 both allelic and functional TCE matching may result in better prediction of survival for patients. These findings provide an attractive new algorithm to stratify donor choice when several well-matched UD are identified. Disclosures: No relevant conflicts of interest to declare.

Nine families of bread wheat (TC5, TC6, TC7, TC8, TC9, TC10, TC14, 5395-(243AA), and 5395) with resistance to barley yellow dwarf virus and containing putative translocations between wheat and a group 7 chromosome of Agropyron intermedium (L1 disomic addition line, 7Ai#1 chromosome) induced by homoeologous pairing or tissue culture were analyzed. C-banding, genomic in situ hybridization (GISH), and restriction fragment length polymorphism (RFLP) in combination with repetitive Agropyron-specific sequences and deletion mapping in wheat were used to determine the relative locations of the translocation breakpoints and the size of the transferred alien chromatin segments in hexaploid wheat–Agropyron translocation lines. All homoeologous compensating lines had complete 7Ai#1 or translocated 7Ai#1–7D chromosomes that substitute for chromosome 7D. Two complete 7Ai#1 (7D) substitution lines (5395-(243AA) and 5395), one T1BS–7Ai#1S∙7Ai#1L addition line (TC7), and two different translocation types, T7DS–7Ai#1S∙7Ai#1L (TC5, TC6, TC8, TC9, and TC10) and T7DS∙7DL–7Ai#1L (TC14), substituting for chromosome 7D were identified. The substitution line 5395-(243AA) had a reciprocal T1BS∙1BL–4BS/T1BL–4BS∙4BL translocation. TC14 has a 6G (6B) substitution. The RFLP data from deletion mapping studies in wheat using 37 group 7 clones provided 10 molecular tagged chromosome regions for homoeologous and syntenic group 7 wheat or Agropyron chromosomes. Together with GISH we identified three different sizes of the transferred Agropyron chromosome segments with approximate breakpoints at fraction length (FL) 0.33 in the short arm of chromosome T7DS–7Ai#1S∙7Ai#1L (TC5, TC6, TC8, TC9, and TC10) and another at FL 0.37 of the nonhomoeologous translocated chromosome T1BS–7Ai#1S∙7Ai#1L (TC7). One breakpoint was identified in the long arm of chromosome T7DS∙7DL–7Ai#1L (TC14) at FL 0.56. We detected some nonreciprocal translocations for the most proximal region of the chromosome arm of 7DL, which resulted in small duplications. Key words : C-banding, genomic in situ hybridization (GISH), physical mapping, translocation mapping, RFLP analysis.

Trichloroethylene (TCE), trichloroacetic acid (TCA), and dichloroacetic acid (DCA) are commonly found as groundwater contaminants in many regions of the United States. Cardiac birth defects in children have been associated with TCE, and laboratory studies with rodents report an increased incidence of fetal cardiac malformations resulting from maternal exposures to TCE, TCA, and DCA. The objective of this study was to orally treat pregnant CDR(CD) Sprague-Dawley rats with large bolus doses of either TCE (500 mg/kg), TCA (300 mg/kg), or DCA (300 mg/kg) once per day on days 6 through 15 of gestation to determine the effectiveness of these materials to induce cardiac defects in the fetus. All- trans retinoic acid (RA) dissolved in soybean oil was used as a positive control. Soybean oil is commonly used as a dosing vehicle for RA teratology studies and was also used in this study as a dosing vehicle for TCE. Water was used as the dosing vehicle for TCA and DCA. Fetal hearts were examined on gestation day (GD) 21 by an initial in situ, cardiovascular stereomicroscope examination, and then followed by a microscopic dissection and examination of the formalin-fixed heart. The doses selected for TCA and DCA resulted in a modest decrease in maternal weight gain during gestation (3% to 8%). The fetal weights on GD 21 in the TCA and DCA treatment groups were decreased 8% and 9%, respectively, compared to the water control group and 21% in the RA treatment group compared to soybean oil control group. The heart malformation incidence for fetuses from the TCE-, TCA-, and DCA-treated dams did not differ from control values on a per fetus or per litter basis. The rate of heart malformations, on a per fetus basis, ranged from 3% to 5% for TCE, TCA, and DCA treatment groups compared to 6.5% and 2.9% for soybean oil and water control groups. The RA treatment group was significantly higher with 33% of the fetuses displaying heart defects. For TCE, TCA, and DCA treatment groups 42% to 60% of the litters contained at least one fetus with a heart malformation, compared to 52% and 37% of the Utters in the soybean oil and water control groups. For the RA treatment group, 11 of 12 litters contained at least one fetus with a heart malformation. Further research is needed to quantify the spontaneous rates of heart defects for vehicle control rats and to explain the disparity between findings in the present study and other reported findings on the fetal cardiac teratogenicity of TCE, TCA, and DCA.

A 58-year-old man fell into a trichloroethylene reservoir bath head first, during a maintenance degreasing bath and accidentally ingested the solvent. Although he showed deep coma, chemical burns and pneumonia on admission, these symptoms gradually subsided. The concentrations of trichloroethylene (TRI) and its metabolites, trichloroethanol (TCE) and trichloroacetic acid (TCA) in blood and urine were measured during hospitalization. Eight hours after the accident, the concentrations ofTRI and its metabolites in serum were 31.4 μ g/ml TRI, 16.5 μg/ ml TCE and 79.5 μg/ml TCA. The serum TRI concentration decreased to 4.3 μg/ml on the following day. Elimination of TCE and TCA from serum occurred biphasically, the estimated half-lives of each metabolites being about 52.6 and 50.4 h in an initial fast phase and 268.3 and 277.2 h in a subsequent slow phase, respectively. Urinary TRI excretion persisted for the first 2 days. The urinary TCE and TCA excretions were longer than that of TRI with a biphasic decrease and the total amount of TCE excreted during the first 2 days was about two times that of TCA. The half-life of urinary TCE excretion (t½ 25.7 h) was shorter than that of TCA (t½ 52.1 h) in the fast phase but did no difference during the slow phase, with each half-time being about 166.3 h. The kinetics of TRI metabolites in blood and urine in this case were in slight agreement with the results following inhalation exposure previously reported in the literature.

In this study, we aimed to investigate disulfide/thiol homeostasis in trichloroethylene (TCE) exposure. The study was carried out in 30 nonsmoker TCE-exposed workers with a variety of occupations. Additionally, 30 healthy nonsmoker volunteers were recruited as the control group. TCE exposure was determined by measuring urinary trichloroacetic acid (TCA) concentration. Median urinary TCA levels of exposed workers (20.5 mg/L) were significantly higher than control subjects (5 mg/L). Thiol and disulfide concentrations were determined using a novel automated method. Disulfide/thiol ratio was significantly higher in the exposed group ( p < 0.001). Thiol/disulfide homeostasis was found to be disturbed in TCE-exposed workers. We predict that in TCE-exposed workers this disturbance can be a therapeutic target, and the efficiency of the treatment can easily be monitored by the novel method we used.

ABSTRACT Reductive dehalogenase (RD) gene transcript levels in Dehalococcoides ethenogenes strain 195 were investigated using reverse transcriptase quantitative PCR during growth and reductive dechlorination of tetrachloroethene (PCE), trichloroethene (TCE), or 2,3-dichlorophenol (2,3-DCP). Cells grown with PCE or TCE had high transcript levels (greater than that for rpoB) for tceA, which encodes the TCE RD, pceA, which encodes the PCE RD, and DET0162, which contains a predicted stop codon and is considered nonfunctional. In cells grown with 2,3-DCP, tceA mRNA was less than 1% of that for rpoB, indicating that its transcription was regulated. pceA and DET0162 were the only RD genes with high transcript levels in cells grown with 2,3-DCP. Proteomic analysis of PCE-grown cells detected both PceA and TceA with high peptide coverage but not DET0162, and analysis of 2,3-DCP-grown cells detected PceA with high coverage but not TceA, DET0162, or any other potential RD. Cells grown with PCE or 2,3-DCP were tested for the ability to dechlorinate PCE, TCE, or 2,3-DCP with H2 as the electron donor. 2,3-DCP-grown cells were unable to dechlorinate TCE but dechlorinated PCE to TCE without a lag, and PCE-grown cells dechlorinated 2,3-DCP without a lag. These results show that 2,3-DCP-grown cells do not produce TceA and that DET0162 is transcribed but its translation product is not detectable in cells and are consistent with PceA's being bifunctional, also serving as the 2,3-DCP RD. Chlorophenols naturally occur in soils and are good candidates for the original substrates for PceA.

Objectivo/tema: Os Traumatismos Crânio Encefálicos são uma das causas de alterações de fala. Podem provocar vários tipos de lesões, entre as quais se encontram as perturbações motoras da fala. Dentro destas lesões temos a disartria, definida como um distúrbio da expressão verbal causada por alteração do controle muscular dos mecanismos da fala, nomeadamente dos órgãos fono-articulatórios. Na disartria existem alterações na produção do discurso, que podem ser analisadas, acusticamente, por diferentes parâmetros. Método: Foi realizada uma análise acústica de vários parâmetros (taxa de elocução, taxa de articulação, velocidade de leitura, diadococinésia e VOT) em produções de 2 pacientes, de géneros diferentes, com disartria póstraumatismo crânio-encefálico. Resultados: Como principais resultados, verificaram-se, de uma forma geral, uma lentificação na fala de ambos os sujeitos, com uma diminuição dos parâmetros analisados, à excepção das taxas de elocução e articulação para o sujeito masculino. Estes parâmetros para este sujeito encontram-se próximos dos valores normais, devido a este paciente se encontrar em fase final de tratamento. Discussão: Os resultados obtidos neste trabalho vêm ao encontro de muitos estudos (para outras línguas) consultados na revisão bibliográfica realizada, tendo-se verificado uma relação entre a severidade da disartria e as alterações de fala verificadas. Será importante, para estudos futuros, aumentar o número e a variabilidade de pacientes a analisar. ABSTRACT: Objective / theme: Traumatic brain injuries are one of the causes of changes in speech. They can cause various types of problems, among which are the motor disorders of speech. Within these we have dysarthria, defined as a verbal expression disorder caused by change on the control of the mechanisms of speech, particularly the phono-articulation organs. Method: Acoustic analysis of various parameters (speaking rate, articulation rate, speed reading, diadochokinesis and VOT) of productions of one male and one female patients with dysarthria due to traumatic brain injury. Results: The main result was the slower speech for both subjects, reflected on the alterations of several measured parameters, with the exception of speaking and articulation rates to the male subject. These parameters for the male subject, at the final stage of treatment, were close to normal. A relation between the severity of dysarthria and changes of recorded speech was found. Discussion: The results of this study are in agreement to the results reported for other languages. The use of only two subjects prevents generalization of the results, increasing the number and variety of patients should be a priority in future studies.

Objectivos: Conhecer valores de análises acústicas de voz para os parâmetros F0, jitter, shimmer e HNR de pessoas com disartria atáxica, por TCE, e contribuir para uma caracterização objectiva do tipo de voz destas pessoas. Métodos: Criou-se um corpus e efectuou-se a gravação de voz de duas pessoas de género diferente, ambas com disartria atáxica por TCE. Realizou-se a anotação de vogais, a extracção dos parâmetros acústicos referidos e, posteriormente, a análise acústica. Resultados: Os valores obtidos foram distintos entre informantes. O informante masculino, com severidade ligeira, obteve resultados próximos dos valores considerados para a normalidade. A informante feminina, com severidade moderada, apresentou resultados significativamente desviantes da normalidade, na maioria dos parâmetros. Para ambos, a F0 foi o parâmetro com valores médios mais próximos do dito normal. Jitter e, principalmente, shimmer apresentaram os valores mais desviantes da normalidade. Conclusão: Foram obtidos valores para a análise acústica de voz de pessoas com disartria atáxica, por TCE, para F0, jitter, shimmer e HNR. Os valores foram diferenciados para as duas fases evolução presentes neste estudo: severidade ligeira e moderada. ABSTRACT: Objectives: Find values of acoustics voice analyses for the parameters F0, jitter, shimmer and HNR of people with ataxic dysarthria, for TBI and contribute for an objective characterization of the type of voice of this people. Methods: It was created a corpus and it was effectuated the record of voice of two people of different genre, both with ataxic dysarthria for TBI. It was made the annotation of vowels, the extraction of the cited parameters and, afterward, the acoustic analysis. Results: The obtained values were distinct between the informers. The masculine informer, with mild severity, had average results near to values considered for normality. The feminine informer, with moderate severity, presented results significantly out of normality, in the majority of the parameters. For both, F0 was the parameter nearer to normal. Jitter and, mainly, shimmer, had values more distant from normality. Conclusions: There were achieved values for acoustic analysis of people with ataxic dysarthria, for TBI, for F0, jitter, shimmer and HNR. The values had been differentiated for the two phases of evolution on this study: mild and moderate severity.

O objetivo deste estudo é levantar a influência da criação da Escola de Consta e Gestão do Tribunal de Contas do Estado do Rio de Janeiro na mudança da percepção da imagem da marca coorporativa do Tribunal de Contas do Estado do Rio de Janeiro segundo a percepção dos servidores. O estudo foi feito sob o enfoque da fenomenologia, sendo dado tratamento de categorias filosóficas para a percepção e para a imagem. O conceito de marca foi analisado sob o enfoque do marketing. A pesquisa de campo foi feita por meio de entrevistas semi-estruturadas e desenhos elaborados pelos respondentes. Chegou-se à conclusão que a criação da ECG influenciou a percepção de mudança na imagem do TCE, embora tal influência não tenha sido notada na percepção da missão institucional da organização.

Streszczenie:
Chloroform and trichloroethene (TCE) are two organic contaminants commonly encountered in ground water. TCE, formerly a common cleaning solvent, is usually associated with contaminated aquifers. Chloroform is usually associated with the chlorination of municipal water. The remediation level for TCE in aquifers is typically 5 ppb, therefore, the analytical method employed for monitoring these analytes must be capable of detecting and quantifying the analytes in the low ppb concentration range. The most common analytical methodology for the determination of TCE or chloroform in water is a purge and trap technique for sample introduction into a gas chromatographic system equipped with electroconductivity or mass spectroscopy detector. The instrumentation has a method limit of detection (LOD) of less than 0.5 ppb for TCE and chloroform, however, the expense, size and complexity of the gas chromatographic techniques limit its use outside the laboratory environment. An alternative to the gas chromatographic method for the analysis of select volatile chlorinated compounds in the low concentration range is an analytical instrument based on a halocarbon-specific optrode. The principle of detection is a quantitative, irreversible chemical reaction (modified Fujiwara reaction) that forms visible light-absorbing products. The operational basis of the optrode is the measure of the time history of the development of the colored (red) product formed by the reaction of the target analytes. The optrode has the selectivity and sensitivity for monitoring TCE and chloroform at the low ppb concentration range in the presence of other volatile chlorinated contaminants. The low-power requirements and simplicity of design make it a good choice for remote operations. This paper presents the analytical results (January 2002, to December 2002) of a panel-mounted instrument used to monitor the influent and effluent water of a TCE treatment facility located in Scottsdale, Arizona, and the analytical results of a well-mounted instrument used to monitor ground water (May 2002, to August 2002) at Edwards Air Force Base, California.

Na última década, os laboratórios de inovação têm se tornado cada vez mais frequentes e importantes para alavancar a inovação em todas as esferas e áreas de atuação do setor público brasileiro. No entanto, os relatos sobre o processo de desenvolvimento desses laboratórios ainda são escassos e superficiais. Neste artigo, apresentamos um estudo de caso descritivo do Prisma Lab, laboratório de inovação do Tribunal de Contas do Estado de Pernambuco (TCE-PE). Através de uma cooperação técnica com a academia, o TCE-PE pôde estruturar a o seu laboratório, que adota um modelo de inovação aberta para enfrentar os variados desafios da instituição, ampliar os seus resultados e legitimar sua relevância para a sociedade.

Streszczenie:
Most recent implementations of the Atkinson cycle are not optimal from the point of view of Thermal Conversion Efficiency (TCE). For example, Toyota has put in its Prius II a gasoline engine which should achieve high efficiency by using a modified Atkinson cycle based on variable intake valve timing management. Firstly, this implementation of the Atkinson cycle is not the optimal solution because some of the air is first sucked from the intake manifold into the cylinder and subsequently returned back there. As a consequence, the oscillating air stream considerably reduces the thermal conversion efficiency of this cycle. Secondly, this implementation of the Atkinson cycle reaches only low levels of Indicated Mean Pressure (IMEP) and, thirdly, it is not suitable for part load Engine Operating Points (EOP) because of the lower TCE. For these reasons, this implementation of the Atkinson cycle is suitable only for hybrid vehicles, where the engine — because it is not directly linked mechanically to the wheels — works only in its best EOP. In this paper the losses in TCE of Internal Combustion Engine (ICE), especially for the Atkinson cycles, are analyzed in detail and a proposal is made for their reduction for aspirated and especially for high pressure supercharged engines.

Trichloroethylene (TCE) releases from leaks and spills next to a large government building occurred over several decades with the most recent event occurring 20 years ago. In response to a perceived conventional vapor intrusion (VI) issue a sub-slab depressurization system (SSDS) was installed 6 years ago. The SSDS is operating within design limits and has achieved building TCE vapor concentration reductions. However, subsequent periodic TCE vapor spikes based on daily HAPSITE™ measurements indicate additional source(s). Two rounds of smoke tests conducted in 2017 and 2018 involved introduction of smoke into a sanitary sewer and storm drain manholes located on effluent lines coming from the building until smoke was observed exiting system vents on the roof. Smoke testing revealed many leaks in both the storm sewer and sanitary sewer systems within the building. Sleuthing of the VI source term using a portable HAPSITE™ indicate elevated vapor TCE levels correspond with observed smoke emanation from utility lines. Sleuthing activities also found building roof materials explain some of the elevated TCE levels on the 2nd floor. Installation of an external blower in the roof truss space has greatly reduced TCE levels. Preferential VI pathways and unexpected source terms may be overlooked mechanisms as compared to conventional VI.

Sleuthing of the VI source term using a portable HAPSITE™ indicate elevated vapor TCE levels correspond with observed smoke emanation from utility lines. In some instances, smoke odors were perceived but no leak or suspect pipe was identified suggesting the odor originates from an unidentified pipe located behind or enclosed in a wall. Sleuthing activities also found building roof materials explain some of the elevated TCE levels on the 2nd floor. A relationship was found between TCE concentrations in the roof truss area, plenum space above 2nd floor offices, and breathing zone of 2nd floor offices. Installation of an external blower in the roof truss space has greatly reduced TCE levels in the plenum and office spaces. Preferential VI pathways and unexpected source terms may be overlooked mechanisms as compared to conventional VI.
