One of the primary challenges associated with inorganic wastewater is its toxicity. Heavy metals such as lead, cadmium, mercury, and arsenic are often found in significant concentrations in industrial effluents. These metals can accumulate in the food chain, leading to severe health issues in humans and wildlife, including neurological disorders, developmental problems, and cancer. Additionally, high salinity levels can adversely affect aquatic life, disrupting ecosystems and biodiversity.
