Water pollution can be caused by a variety of sources, including industrial waste, agricultural runoff, sewage discharge, and other human activities.

Lead is a toxic metal that can cause a range of health problems, including neurological disorders and developmental problems in children.

Diarrhea is the most common waterborne disease worldwide, causing significant morbidity and mortality, especially among children in developing countries.

Trichloroethylene (TCE) is a known carcinogen and can increase the risk of bladder cancer. It is a common industrial solvent that can contaminate drinking water sources.

Water pollution can affect human health through ingestion of contaminated water, skin contact with contaminated water, and inhalation of contaminated water vapors.

Cadmium is a toxic metal that can cause kidney damage and high blood pressure. It can contaminate drinking water sources through industrial activities and mining.

Water pollution can affect aquatic ecosystems through direct toxicity to aquatic organisms, habitat degradation, disruption of food webs, and other mechanisms.

Aflatoxin is a naturally occurring toxin produced by certain fungi that can contaminate water sources. It is known to cause liver damage and cancer.

Agricultural runoff pollution is caused by fertilizers, pesticides, herbicides, and other chemicals used in agricultural practices.

Norovirus is a waterborne disease caused by a virus that can cause severe gastrointestinal symptoms, including vomiting and diarrhea.

Water pollution can affect human health through ingestion by direct toxicity of pollutants, contamination of food and water sources, and disruption of nutrient absorption.
