Fish Accumulate Human Drugs

Waste flowing from sewage-treatment plants is ending up in fish. The highest levels were in the fish's brains and livers. Fortunately, the muscles commonly eaten in fish fillets had much lower levels. In the United States water-quality standards do not regulate pharmaceuticals in reclaimed wastewater. With water reclamation becoming increasingly important in the country's arid western states, drug compounds could become more widespread in rivers and streams. This study only looked at antidepressants, but previous studies show that the entire range of human drugs are in the water supply. Just another reason you want to make sure you are drinking clean water.
