Contaminants can be physical, chemical, or biological in nature and can be inactivated through various processes. Chemical pollution in water, biological pollution with pathogenic microbes, and the classification of environmental hazards are crucial concepts related to contaminants.
Contaminants can be physical, chemical, or biological in nature. They can be inactivated through various processes such as dilution, photodecomposition, biological degradation, chemical reactions, and absorption into plants or soil.
Chemical pollution in water resources includes toxic metals, organic compounds, and radioactive waste. Biological pollution involves pathogenic bacteria and parasites. Physical pollution comprises sediment, trash, and changes in temperature affecting aquatic fauna.
Environmental hazards are classified into biological, chemical, and physical categories, which can interact and exacerbate each other's effects. Contaminants are present in various environmental settings and can affect food during production, storage, and consumption.
