The state of the debate: while scientists agree that some synthetic chemicals can mimic hormones, consensus on a course of action remains elusive

Article Abstract:

Several research studies have indicated that some chemicals can cause sperm count reduction, and increase incidences of breast cancer and prostate cancer. This is because certain chemicals can imitate, hinder and change hormones. Experiences with DDT and the synthetic hormone diethylstilbestrol also demonstrate the negative effects of such hormone disruptors. However, critics maintain that there is still no evidence to indicate that chemicals in the environment are really toxic to humans and that dangerous chemicals such as DDT have already been banned.

Endocrine disruptors and breast cancer

Article Abstract:

The Silent Spring Institute initiated an ongoing research to determine whether estrogenic chemicals commonly found in the environment increase breast cancer risk. Cape Cod as a region has higher incidence of breast cancer compared to other towns. Moreover, the Cape has been known to have been exposed to pesticides. It has also sandy soils over shallow aquifers which indicate the possibility of drinking-water contamination from septic tanks. Human wastes contain excreted pharmaceuticals and endogenous estrogen.

The precautionary approach: as researchers painstakingly explore the exact mechanism of endocrine disruption, we should consider suspect chemicals guilty until proven innocent

Article Abstract:

Research findings on the toxic effects of chemical endocrine disruptors on animals, including humans, suggest that a precautionary approach be taken for industrial chemicals and other environmental pollutants. The traditional principle that a higher dose of a particular chemical would have a greater impact cannot be relied on for endocrine disruptors. Thus, industries must first show that the chemicals they are introducing have no adverse effects before their products are to be allowed to be marketed.
