2024年7月5日 · Trihalomethanes are a type of chemical disinfection byproduct (DBP) that occur in disinfected drinking water supplies. 💡 There are several kinds of THMs in water: chloroform, bromodichloromethane, bromoform, and dibromochloromethane.

2022年12月16日 · Total trihalomethanes (TTHM) are a group of disinfection byproducts that form when water disinfectants such as chlorine or ozone react with other naturally occurring chemicals in the water. They are colorless and will evaporate out of the water into the air. There are four significant TTHM potentially found in disinfected drinking water

For each chemical contaminant or substance considered, a lead institution prepared a health criteria document evaluating the risks for human health from exposure to the particular chemical in drinking-water.

Trihalomethanes are a group of chemicals that can form when organic matter in water is treated with halogen disinfectants such as chlorine. The most common of these chemicals is

People may be exposed to TTHM in drinking water from ingestion (i.e., drinking the water and ingesting it in foods and/or ice prepared with the water). In addition, TTHM vaporize readily into the air so inhalation

Trihalomethanes (THMs) have been proven to be potentially genotoxic and mutagenic for human. The aim of this study was to characterize the THMs spatiotemporal distribution and its carcinogenic risk potential in Ardabil water distribution system.

Trihalomethanes (THMs) are a group of compounds that can sometimes be found in chlorinated water that is drawn from a source with high levels of organic materials. THMs are by-products of the process of disinfecting water (i.e. the addition of chlorine to water systems).

2006年5月26日 · Our vision and mission are the attainment by all peoples of the lowest possible burden of water and sanitation-related disease through primary prevention. Trihalomethanes are considered in the WHO Guidelines for Drinking-water Quality (GDWQ).

2022年5月18日 · Chapter 12 of the Guidelines for drinking-water Quality (GDWQ) includes fact sheets on chemical contaminants, based on comprehensive review documents published by WHO.

The primary trihalomethanes of concern in drinking water are chloroform, bromodichloromethane, dibromochloromethane, and bromoform. What are the Health Risks for Trihalomethanes?
