Indirect contamination occurs when harmful substances or microorganisms are transferred to a surface, object, or person through contact with contaminated materials such as hands, clothing, or equipment. This type of contamination does not directly result from contact with the source of contamination but occurs through secondary means.

Direct contamination occurs when harmful substances are introduced directly into a medium, such as water or soil, often through spills or leaks. Indirect contamination, on the other hand, happens when pollutants enter the environment through secondary pathways, such as runoff from contaminated surfaces or through the food chain. While direct contamination poses immediate risks, indirect contamination can lead to more widespread and often delayed effects. Both forms of contamination can significantly impact ecosystems and human health.
Correct, the Chernobyl nuclear power plant did not have secondary containment structures in place to prevent the leakage of radioactive materials in the event of a nuclear accident. This lack of secondary containment contributed to the widespread environmental contamination following the Chernobyl disaster in 1986.
contamination of water resources by excessive inputs of nutrients is called resource contamination
