Halomethanes are a group of chemical compounds that have drawn a lot of interest because of how common they are in the environment and because of the potential harm they could do to human health and the environment. One or more halogen atoms, such as chlorine, bromine, or iodine, linked to the methane (CH4) backbone describe these compounds, which are what they are made of. Chloromethane (CH3Cl), bromomethane (CH3Br), and iodomethane (CH3I) are the three most typical halomethanes, while there are many additional varieties with different numbers and kinds of halogen substituents. Halomethanes are produced naturally by marine creatures like seaweed and some forms of algae, which is one of the main sources of halomethanes in the environment. The use of chlorinated solvents in industrial processes, the disinfection of drinking water and wastewater, and the burning of fossil fuels are other anthropogenic activities that might result in the formation of halomethanes. Halomethanes are thus present in a range of environmental media, such as the air, water, soil, and sediments. Halomethanes may be present in nature, but their high levels in the environment can have negative impacts. For instance, bromomethane and chloromethane in particular are known to contribute to the thinning of the ozone layer in the high atmosphere. Increased amounts of harmful ultraviolet (UV) radiation that reach the Earth's surface as a result of this ozone hole could have an impact on ecosystem stability and human health. Additionally, some halomethanes, especially those containing chlorine, have the ability to linger in the atmosphere for long periods of time and travel great distances, creating the possibility of worldwide distribution and environmental buildup. By changing the chemistry of the water and interfering with aquatic species' metabolic activities, these substances have an effect on aquatic life in aquatic systems. Halomethanes are a varied class of chemical compounds that have both anthropogenic and natural sources. Their existence in the environment prompts worries about their possible negative effects on the environment and human health, including ozone depletion and long-term health risks. To address these issues and reduce halomethane exposure while protecting ecosystems and human health, a multidisciplinary strategy encompassing environmental research, chemistry, toxicology, and public policy is necessary
