Thms can be absorbed through skin or inhaled by breathing water vapour when showering, bathing, etc. Boiling water for one minute can reduce trihalomethane concentration by up to 75%. Understand how these disinfection byproducts arise, their health relevance, and steps for safer water.
These documents and the analyses contained therein provide estimates of the levels of contaminants in drinking water that would pose no significant health risk to individuals. Trihalomethanes are a group of volatile and potentially toxic chemical compounds formed when water is treated with chlorine, which then reacts with organic matter in water. Recognition of public health consequences of chemical contamination of drinking water is essential for people and concerned authorities.
As thms are volatile in drinking water, and maybe released into the air during showering and through a range of household activities; Boiling water can also significantly reduce thm concentrations due to their volatile nature. The potential human health effects. Lifetime exposure to disinfection byproducts (dbps) in municipal water may pose risks to human health.
Adequate indoor ventilation helps to reduce inhalation. Drinking water standards are called maximum contaminant levels (mcls). Current approaches of exposure assessments use.
