Chemical pollutants are rife across the world’s oceans

A recent study has found that synthetic chemicals, like those used in plastics and personal-care products, are present in all types of marine environments. These chemicals make up about 20% of the dissolved organic matter in coastal waters. The study also discovered high levels of pesticides and pharmaceutical chemicals in these waters. This is important because it shows how human-made pollution is affecting our oceans, which can harm marine life and potentially impact human health. Understanding the extent of this pollution can help us find ways to reduce it and protect our environment. QUESTION: How might the presence of synthetic chemicals in the ocean affect the food chain and, ultimately, human health?
