UN Expert: Pharma Drugs in Water Sources Affecting Human Reproductive System.

The aquatic and human health consequences of pharmaceutical drugs entering the environment through wastewater treatment plants is not yet well understood.

As the world’s population expands and we become wealthier, drugs and chemical-based care products become more prevalent. While pharmaceuticals are essential for human health and well-being, less is known on the effects they have on the freshwater sources on which we depend for our existence, and their impact on human health and biota.

The occurrence of pharmaceutical substances in the environment is of global concern. According to a study published in June 2018 in the United States of America – Pharmaceutical manufacturing facility discharges can substantially increase the pharmaceutical load to U.S. wastewaters  drug manufacturing facilities are an important source of environmental pollution. Wastewater treatment plants are unable to filter out chemical compounds used to manufacture personal care products and drugs, so these chemicals seep into freshwater systems and into the oceans.

For some time, evidence has been mounting that chemical pollution may be entering the food chain and altering the sex functions of fish. But these effects may not be limited to fish. Research suggests that exposure to pharmaceuticals and other chemicals in drinking water may affect human reproductive systems too.
A 2017 UNESCO study titled Pharmaceuticals in the aquatic environment of the Baltic Sea region found that the chemicals’ main pathway into the freshwater and marine environment was via the discharges of effluents from municipal wastewater treatment plants.
“Only nine out of 118 assessed pharmaceuticals were removed from wastewater during the treatment processes with an efficiency of over 95 per cent, and nearly half of the compounds were removed only partially with an efficiency of less than 50 per cent,” says the report.

Water, despite the built-up infrastructure and technology around it, is ultimately an environmental good that comes from and returns to nature. Pollution of water-related ecosystems directly threatens people’s health and livelihoods, as well as economic, political and security developments within countries and in their relations with other countries.
