title: [Study on the environmental pollution of PCBs].
abstract: 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. It was random and stated to extract samples of piped water, farmland rice and eggs. Then, the exceed-mark-quantity detecting methods were used to detect the PCBs and TEOs level in these samples.
  
  
  RESULTS
  The content of PCBs in the samples was different except for piped water. Thediversity of the PCBs level in the hen's eggs was the most significant, duck's eggs took second place and farmland was the least. The order of PCBs level in the samples was: hen' s eggs > duck's eggs > farmland > rice > river water ( stream) > piped water.
  
  
  CONCLUSIONS
  The content of PCBs in each sample from Town F was higher than town P and town DXG on different levels. So the industry of taking the disused transformer apart had caused pollution of local environment.
