Nanomaterials can enter aquatic systems through various pathways:
Industrial Effluents: Factories and manufacturing plants often discharge nanomaterials directly into water bodies. Wastewater Treatment Plants: These facilities are not always equipped to filter out nanomaterials completely. Agricultural Runoff: Pesticides and fertilizers containing nanomaterials can wash into rivers and lakes. Consumer Products: Personal care products, paints, and textiles can release nanomaterials during use and disposal.
