1-bromopropane has lower Ozone Depletion and Global Warming Potential, 1-bromopropane can be also used to clean all types of grease, wax, flux. Therefore, it is often chosen to replace CFC organic solvents. Recent animal studies indicated that 1-bromopropane will damage the neuro- and reproductive systems. For human, the exposure of 1-bromopropane may result in numbness, leg weakness, swallowing and urination difficulty. The National Institute for Occupational Safety and Health suggested that the threshold limit of 1-brmopropane is 0.1 ppm. In Taiwan, Institute of Labor, Occupational Safety and Health, Ministry of Labor suggested that the recommended exposure limit-time weighted average (REL-TWA) is 0.1 ppm as well. In this study, we investigated the application of P&T system on 1-bromopropane . The results showed that this technique can be applied to analyze urinary 1-bromopropane.The detection limit was 0.05 ng/mL. The various amounts of NaCl and CaCl2 we added into samples to evaluate the salting out effects on 1-bromopropane. In result, added salts didn’t increase the recovery. Urinary 1-bromopropane can be well preserved at 4℃ in a glass tube without headspace for at least 14 days. A P&T-GC-FID system can be successfully applied to analyze urinary 1-bromopropane. The technique was feasible, simple and sensitive. For those working in the environment with 1-bromopropane, the exposure scenario can be described by urinary 1-bromopropane determined by purge & trap GC-FID system. Thus, this related adverse health effects can properly be prevented.

In order to understand workers’ exposure to 1-bromopropane, in this study three factories (symbolized by A, B and C) with the usage of 1-bromopropane in their manufacturing processes were recruited to monitor personal air exposure for workers and environmental air for manufacturing areas. The personal exposure sampling was conducted in a typical 8-hour work shift. A partial period (at least 6 hours) single sample measurement was taken for both personal and environmental sampling. The worker was asked to wear a personal sampling pump equipped with an anasorb tube and a stainless steel thermal desorption tube with chromosorb absorbent. A manifold was connected to the sampling pump to simultaneously set up the flow rates of the anasorb tube and the thermal desorption tube at 200 and 180 mL/min, respectively. The sampling tubes were attached to the worker’s collar for breathing zone sampling. These two types of sampling tubes with the inlet placed at a height of 1.5 meters above the floor were also used for environmental sampling. All of the anasorb tubes were analyzed by gas chromatography/mass spectrometry (Agilent 6890N/Agilent 5973N-MSD). The thermal desorption tubes were analyzed by a thermal desorbers PerkinElmer TurboMatrix ATD-50) equipped with gas chromatography (Agilent-6890). The 8-hour time weighted average (8-h TWA) exposure of 1-bromopropane was calculated for both personal and environmental measurements. A total of 39 personal samples and 122 environmental samples were collected for 19 workers in the factories. The mean (± standard deviation) of 8-h TWA exposure was 5.578 (±8.627) ppm for all personal measurements. The means (± standard deviations) of personal measurements for A. B and C factories were 0.046 (±0.010) ppm, 9.551 (±10.253) ppm and 4.283 (±7.662) ppm, respectively. The means (± standard deviations) of environmental measurements for A. B and C factories were 2.399 (±1.724) ppm, 7.690 (±7.295) ppm and 8.925 (±11.587) ppm, respectively. There was no statistically significant correlation between 1-bromopropane measurements taken by anasorb tubes and thermal desorption tubes for both personal and environmental sampling. This indicated that it was not possible to use the thermal desorption tube with chromosorb absorbent to replace the anosorb tube for 1-bromopropane sampling. The 8-h TWA exposures of 1-bromopropane for the workers in A, B and C factories were far below, close to one time, and close to 1/2 times of the recommended occupational exposure limit (10 ppm), respectively. Some workers in certain work environments still needed to have careful control for their exposure to 1-bromopropane to reduce the risk of potential health hazard due to 1-bromopropane exposure.

Background: Hairdressers often have occupational dermatitis on hands due to contact with chemical agents. The highest rate of use in variety of chemicals is perming agents. The frequency, time, and type of glove wearing behavior on hairdressers are inconsistent and may cause that skin is exposed to irritants and allergens. Metal cleaning technology is an important part of industry. Workers in those indistries might contact with large amounts and are exposed to high level concentrations of metal cleaning agents, but they usually don’t wear protective gloves or wear wrong types of gloves while working. These direct dermal contanct might increase the exposure dose of the organic solvents.. Therefore, it is necessary and important to establish a correct approach to selection of protective gloves to prevent occupational disease. Aim: To investigate permeation behaviors of hairdressing and industrial recommended gloves for cumulative exposure to thioglycolic acid and sodium bromate, and single exposure to 1-bromopropane by ASTM F739-12 standard permeation test method. Material and Method: Thioglycolic acid was quantified by high performance liquid chromatography with an UV-Vis detector (HPLC-UV) at wavelengths 214 nm and sodium bromate was quantified by UV-Visible spectrometer at wavelength 440 nm, respectively. 1-Bromopropane was quantified by gas chromatography with a FID detector (GC-FID). The concentrations of test solutions for the permeation tests were thioglycolic acid 11% (w/v), sodium bromate 11.5% (w/v), and 1-bromopropane 99%. The test temperature was 27C. The permeation sample was collected every 15 minutes. The test durations were 4 hours for black natural rubber latex (BNRL) gloves and polyvinylchloride (PVC) gloves for perming agents, and 2 hours for natural rubber latex (NRL) gloves, nitrile gloves, butyl rubber gloves and 4 hours for Silver Shield® in the 1-bromopropae permeation tests. Each identical permeation test was performed triplicate. Wilcoxon sign-rank tests were used to statistically examine the differences of the weight and thickness of the test gloves both before and after the tests. Results: For thioglycolic acid, the average breakthrough times (BTs) were 90 minutes for BNRL glove, 25.0±8.66 (15-30) minutes for PVC glove; the maximum cumulative permeation masses were 228.79 µg for BNRL glove, and 900.61 µg for PVC glove; and the maximum permeation rates were 3.11 µg/cm2/min for BNRL glove, 12.25 µg/cm2/min for PVC glove. For 1-bromopropane, the average breakthrough times (BTs) were 15 minutes for NRL gloves, nitrile gloves and butyl gloves; the maximum permeation masses were 4869.63 mg for NRL glove, 5136.07 mg for nitrile glove, 3490.56 mg for butyl glove; the maximum permeation rates were 8.28 mg/cm2/min for NRL glove, 8.73 mg/cm2/min for nitrile glove, 5.94 mg/cm2/min for butyl glove. No breakthrough was detected for Silver Shield® for the 4-hour tests. Conclusions: BNRL gloves provide the best protection between two tested gloves in perming agents test, but hairdressers should change their gloves frequently and not over 90 minutes. PVC gloves were not recommended to the hairdressers because of the short BTs (15-30 minutes) of thioglycolic acid. The protection of two gloves for sodium bromide was not affected by the breakthrough of thioglycolic acid. NRL gloves, nitrile gloves, and butyl rubber gloves were not recommended to the workers while contacting 1-bromopropane. Only silver shield® gloves can be used to prevent the dermal contact of 1-bromopropane for at least four hours according to the present study.

The of alkenes chemistry on catalyst surfaces (metals and metal oxides) have been the subject of intense studies. In this thesis, the adsorption, thermal reaction, and photochemistry of 3-iodopropene, 2-bromopropene and 1-bromopropene were studied on powdered TiO2 by Fourier-Transformed infrared spectroscopy (FT-IR). 3-Iodopropene was adsorbed dissociatively, forming acrolein species on TiO2, as observed by the IR absorption peaks at 2809 cm-1 (ν=CH2), 1690 cm-1 (ν C=O), 1642 cm-1 (νC=C), 1430 cm-1 (δ CH2), 1366cm-1 (δ CH), 1293 cm-1 (δ CH) and 1160 cm-1 (νC-C). No significant decomposition reaction occurred after extended photooxidation on high temperature heat treatment. 2-Bromopropene also adsorbed dissociatively on TiO2 as indicated by the IR adsorption peaks at 1161 cm-1 (νC-C), 1387 cm-1 (δs CH3), 1441 cm-1 (δas CH3), 1635 cm-1 (νC=C), 2936 cm-1 (νs CH3) and 2979 cm-1 (νas CH3). Upon irradiation, the formation of acetate and formate species on TiO2 were oberserved absorption as indicated by IR at 1560 cm-1 (νas COO), 1442 cm-1 (νs COO), 1350 cm-1 (δs CH3) acetate and at 1560 cm-1 (νas COO)、1378 cm-1 (νs COO) formate observed. The results presented in this thesis can be successfully explained by two literature reported reaction pathways for similar reaction systems.

Organic halides have good photo activity on TiO2. In this thesis, the adsorption and interaction of 1-，2-，3-bromopropene on powdered TiO2 were studied using FTIR(Fourier Infrared) technique. The result shows that 3-bromopropene chemically adsorbed on powdered TiO2 to form aldehyde species as vindicated by the absorption peaks at C-O (1087 cm-1)、CH2 (1392 cm-1)、C-H (1425 cm-1)、CH3 (1451 cm-1) and C=O (1688 cm-1). In the case of 2-bromopropene, only absorption peaks at C=O (1698 cm-1) and CH2 (1242 cm-1) were observed, indicating the formation of carbonyl group on TiO2. As for 1-bromoropene, the peaks are almost identical to gas phase ones, therefore, no chemisorption on TiO2 was concluded. The Br-C bond breaking capability of bromopropene strongly depends on the substituted position of bromine which consequently affect the chemistry of bromopropene on TiO2. After irradiation under the presence of oxygen, all these molecules were decomposed to form carbon dioxide (2352 cm-1). The possible side products and reaction pathway are discussed in the thesis.
