United Kingdom: A recent study conducted along the southern coast of England has uncovered alarming levels of potentially harmful chemicals, including recreational drugs and antidepressants, in water pollution.
Scientists involved in the research have expressed concerns about the negative impact of human drugs on marine life. The researchers have presented evidence showing that estrogen found in the water can cause biological changes that feminize male fish.
The study was coordinated by the Clean Harbour Partnership (CHP), an organization co-founded by Ms. Bianca Carr. Ms. Carr emphasized the need to move beyond discussing general water contamination issues and focus on the specific chemicals present in human waste. She further highlighted the importance of investigating the effects of drugs like cocaine on the water and the food chain. This calls for a broader investigation to be conducted throughout the United Kingdom.
In collaboration with Portsmouth and Brunel University London, campaigners in Hampshire and Sussex analyzed hundreds of water samples from Chichester and Langstone harbours. The research has so far detected more than 50 compounds across 22 sites in over 288 samples. These compounds include pharmaceuticals, diabetes medications, and a chemical produced by the liver after cocaine use. The study also uncovered the presence of banned pesticides in the water.
Furthermore, the researchers discovered high levels of E. coli bacteria, with one post-storm seawater sample near a sewage treatment plant showing readings 760 times higher than the safe levels set by the European bathing water directive.
These findings contribute to the growing efforts along England’s coast to raise awareness about the dangers of water pollution. Rob Bailey, co-founder of CHP, emphasized the significance of community funding in gaining insights into the mixture of chemicals polluting seawater and their sources. The long-lasting presence of certain pesticides and the presence of partially digested antidepressants, diabetes drugs, and bladder infection medications raise concerns about their impact on marine life, as so little is known about it.
