Lipid Peroxidation in Workers Exposed to Al,Ga,In,As,and Sb in Optoelectronic Industry
An observational study of Urine, run by Kaohsiung Medical University Chung-Ho Memorial Hospital at 1 site in Taiwan.
Trial summary
To investigate whether exposure to Al, Ga, In, As, and Sb induces lipid peroxidation in humans. Whole blood and urine levels of 170 workers were analysed by use of ICP-MS. MDA, the product of lipid peroxidation was determined by HPLC Read more about this study
