What common contaminants are associated with industrial discharges?

• A. Food waste, detergents, and pathogens
• B. Heavy metals, organic chemicals, and acids
• C. Carbon monoxide, nitrogen oxides, and ozone
• D. Fertilizers, pesticides, and herbicides

Answer: (B)

Heavy metals, organic chemicals, and acids are indeed common contaminants associated with industrial discharges. These pollutants arise from various industrial processes, which may include manufacturing, mining, and chemical production. Heavy metals like lead, mercury, and cadmium can enter water bodies through runoff or wastewater discharges. These metals are particularly hazardous due to their toxicity and potential for bioaccumulation in aquatic environments, leading to detrimental effects on both wildlife and human health. Organic chemicals, which can include solvents, hydrocarbons, and synthetic organic compounds, often result from industrial activities such as refining, manufacturing, and chemical processing. Many of these substances are toxic, persistent in the environment, and can cause significant ecological harm. Acids, such as sulfuric acid or hydrochloric acid, are frequently generated in industrial processes and pose severe risks to natural water bodies when discharged without adequate treatment. These acids can lead to the acidification of water, negatively affecting aquatic life and altering the chemical composition of ecosystems. The other options mention contaminants that are typically associated with other sources. For example, food waste and pathogens are more relevant to wastewater from food processing or municipal sources, whereas carbon monoxide and nitrogen oxides are mainly emissions from combustion processes, not discharges.
