Objective: To study correlations of polychlorinated biphenyls (PCBs), DIOXIN, and polybrominated diphenyl ethers (PBDE) with thyroid stimulating hormone(TSH) in children, and assess the impact on children's health.
Methods: Three hundred and sixty nine children aged from 6 to 8, including 195 from Luqiao, the computer E-waste recycling area, and 174 from Longyou, the control area, were selected for this investigation to elucidate the correlation of PCBs, DIOXIN, and PBDE with TSH in children's blood samples. The children had a physical examination and their blood levels of PCBs, DIOXIN, PBDE, and TSH were detected after sample collection.
Objective: To Study the health-related effects of PCBs pollution to women and children living near the dismantling factories of disused transformers.
Methods: 49 couples which include a pair of preschool child(8 - 10 years old) and his/her mother were matched as the objects from the central junior school of F neighborhood where the study was progressing. Fasting Venous blood was collected from the objects, in which the content of PCBs (including 13 isomers) was determined by ultrasonic trace analyses methods as well as blood and urine were subjected to biochemical test while investigation by questionnaire and physical examination were also required.
Objective: To investigate the environmental pollution of PCBs from the place where the disused transformers were taken apart.
Methods: Take town F as the high exposed district for investigating and the town P which 100 kilometres is away from the town F as the low exposed district. At the same time, take town DXG which is 500 kilometres away from town F as the district for contrast.
