Reproductive effect and developmental effect of phthalate were reported in peers’ studies. The widespread uses of PAEs result in multiple routes of human exposures, such as ingestion, inhalation, skin absorption or medical contact. The aims of the study were to quantify the extractable masses of six phthalates, dimethyl phthalate (DMP), diethyl phthalate (DEP), benzyl butyl phthalat (BBP), dibutyl phtalate (DBP), di-iso-butyl phthalate (DIBP), and di(2-ethylhexyl) phthalate (DEHP) in different disposable glove materials and the leached out amounts if the glove materials contacted disinfectants. Method: The disposable gloves, polyvinylchloride gloves (PVC), disposable natural rubber latex gloves (NRL), disposable polyethylene gloves (PE), nitrile medical examination gloves, were investigated. The round shape glove sample with a diameter of 25.4 mm was immersed into 10 mL n-hexane and ultrasoniced at 60nC for 3 hours. The removed extracted solutions was concentrated to 0.2 mL under a nitrogen stream and the 摘 amount of 0.8 mL acetonitrile was added into the concentrated solution for HPLC analyses. The leaching test was performed by immersing the glove sample into 5-mL disinfectant (75% ethanol aqueous solution, 2.5% glutaraldehyde aqueous solution, or 1,000 ppm NaDCC aqueous solution) at 25nC, the room temperature. The 要 immersion solution was transferred to a flask and replenished another fresh 5-mL (英 disinfectant solution every 30 min. This procedure was repeated for 120 min. The ) removed 5-mL disinfectant solutions were extracted followed the liquid-liquid phase extraction procedure as mentioned previously. Each experiment condition was proceeded triplicate. All samples were analyzed by HPLC-UV with the gradient elution system (acetonitrile/water) and UV detection wavelength 225 nm. Results: The HPLC-UV linear dynamic range was 2–20 ng/μL for DMP, DEP, BBP, DBP, DIBP, and DEHP with a coefficient of determination (R2) greater than 0.995. The nhexane at 60nC resulted in the best recovery rates and highest amounts of phthalates. The recovery rates (%) were 89.33±2.11 for DMP, 61.75±1.48 for DEP, 95.52±2.32 for BBP, 92.16±1.74 for DBP, 93.15±0.99 for DIBP, and 97.05±4.28 for DEHP. DEHP was extracted in PVC, PE, and nitrile gloves at concentrations of 100.24–114.53 (mg/g PVC glove), 0.87–1.11 (mg/g PE glove) and ND–4.64×103 (mg/g NRL glove), respectively. Six phthalate were detected in NRL glove in a range from 0.79×10-3 to 2.91×10-3 (mg/g NRL glove). DEHP in PVC, NRL and nitrile gloves were able to be leached by 75% ethanol aqueous solution. The dissolved masses were 2.45±0.09 μg for PVC glove, 0.028±0.002 μg for NRL glove and 0.061±0.005 μg for Nitrile glove at 30 min. Conclusions: The result demonstrated gloves did contain the investigated phthalates. More attention should be paid to the medical care personnel to avoid exposure of phthalates through the glove materials. 論 文 目 次 參 考 文 獻 摘要 Ⅰ Abstract Ⅳ Table of contents Ⅶ List of Tables Ⅸ List of Figures Ⅹ Chapter one Introduction 1 Chapter two Literature Reviews 4 2.1 Physicochemical properties of phthalates 4 2.2 PAEs in environment 6 2.3 Routes of exposure to PAEs 8 2.3.1 Ingestion 8 2.3.2 Inhalation 10 2.3.3 Medical contact 10 2.3.4 Skin absorption 12 2.4 Health hazards of PAEs 14 2.4.1 Animal Studies 14 2.4.2 Human health risk of PAEs 17 2.4.3 Risk levels of human health 19 Chapter Three Materials and Methods 21 3.1 Materials 21 3.1.1Chemicals and reagents 21 3.1.2 Apparatus 22 3.1.3 Gloves 23 3.2 Optimization the HPLC-UV condition 24 3.2.1 Selection of eluents 24 3.2.2 UV wavelength selection 24 3.3 Liquid-liquid phase extraction 25 3.4 Leaching test by medical disinfectant 27 3.5 The quality control of sample analysis 29 3.5.1 Blank 29 3.5.2 Standard solutions 29 3.5.3 Calibration curves 29 3.5.4 Recovery rates 29 3.5.5 Procedures for clean up 30 3.5.6 Statistics 30 Chapter Four Results 31 4.1 HPLC conditions 31 4.1.1 Composition of eluents 31 4.1.2 Detector wavelength 32 4.1.3 Calibration Curves 34 4.2 Extraction trial 36 4.2.1 Extraction temperature 36 4.2.2 Extraction solution 36 4.2.3 Recovery rate 37 4.2.4 Extraction trial of three different gloves 39 4.3 Leaching test by medical disinfectant 42 4.4 Glove physical change 46 Chapter Five Discussion 48 5.1 Liquid-liquid phase extraction trial 48 5.2 PAEs content in plastic products 52 5.3 Investigation of leaching test 55 5.4 Limitation 57 Chapter Six Recommendations and Conclusions 58 Chapter Six Recommendations and Conclusions 58 References 60 Abb M, Heinrich T, Sorkau E, Lorenz W.
