[Distribution and sources of endocrine-disrupting pesticides in Beijing Guanting reservoir].
Distribution and sources of endocrine-disrupting pesticides in Guanting reservoir were studied. The results show that pesticide values in a few sites are considerately high considering to being used as a drinking water source. The variation in concentration of pesticides among sites was expected to be caused from several pathways such as contaminants through the rivers and drainage of contaminated water from the surrounding agricultural fields. To reduce exposure to these endocrine-disrupting compounds, the abundant current use of the pesticides in the area and the river watersheds should be minimized and further measures need be taken for using as potable water supply.
