"Becomes contaminated" refers to the process or state of an object, substance, or environment becoming impure, unclean, or tainted by the presence of harmful or unwanted elements. Contamination can occur in various forms, including physical, chemical, biological, or radiological contamination.
In physical contamination, an object or substance becomes polluted or soiled due to the presence of foreign matter such as dust, dirt, or debris. Chemical contamination refers to the introduction of unwanted or harmful chemicals or substances that can alter the purity, composition, or characteristics of a substance or environment. This can happen through accidental spills, leaks, or improper disposal of hazardous materials.
Biological contamination involves the presence of living organisms, such as bacteria, viruses, fungi, or parasites, which may pose health risks and cause illnesses or infections. Examples include contaminated food or water sources leading to foodborne illnesses.
Radiological contamination relates to the presence or accumulation of radioactive materials in an area or object, often resulting from nuclear accidents or improper handling of radioactive substances.
Contamination can have adverse effects on human health, ecosystems, and overall quality of life. It may require remediation efforts such as cleaning, sterilization, purifying, or decontamination to restore the object, substance, or environment to a safe and desirable state. Prevention and proper management practices are critical in minimizing the risks of becoming contaminated and preserving the integrity and safety of various systems or substances.
