Plastic pollution has long been recognized as a major environmental issue, especially in oceans, rivers, and lakes. However, one of its most insidious effects often goes unnoticed— plastic leachates . These are chemical substances that seep from plastics as they degrade in water. While microplastics grab headlines, the leachates they release can silently and severely affect aquatic ecosystems, particularly aquatic plants that are the foundation of many freshwater and marine food chains. Aquatic plants, including algae, seagrasses, and submerged vegetation, play a critical role in maintaining water quality and providing oxygen and habitat. But when exposed to plastic leachates, their physiological functions can be disrupted. Research shows that leachates containing phthalates, bisphenol A (BPA), and other additives can alter photosynthesis, stunt growth, and reduce reproduction in these plants. Even small concentrations of these chemicals may have significant biological effects ov...
