A biocide is a substance that can kill or control harmful organisms, such as bacteria, fungi, and viruses. These chemicals are commonly used in various products, including disinfectants, preservatives, and pesticides, to protect human health and the environment. Biocides work by disrupting the biological processes of the targeted organisms, preventing their growth or reproduction. Biocides are regulated by government agencies to ensure their safety and effectiveness. They are essential in many industries, including healthcare, agriculture, and water treatment, where maintaining hygiene and preventing contamination is crucial. Proper use and disposal of biocides are important to minimize potential risks to humans and wildlife.
