Chlorine is the most common chemical disinfectant applied in food production facilities to reduce the transmission and occurrence of foodborne infectious diseases . Disinfection by-products (DBPs) have emerged as a toxicity problem associated with the use of disinfectants in water treatment and food production. More than 800 DBPs have been identified in drinking water , which form when disinfectants react with naturally occurring organic matter (NOM), anthropogenic contaminants, and brominated and iodinated compounds present in source water . Emerging organic micropollutants (EOMPs) are abundant in water systems and include synthetic and naturally occurring chemicals, e.g., pharmaceuticals, personal care products, pesticides, and industrial chemicals, which pose a toxicological risk to human and environmental ecosystems . The formation of DBPs, specifically trihalomethanes (THMs), i.e., trichloromethane (CHCl 3 ), tribromomethane (CHBr 3 ), bromodichloromethane (CHCl 2 Br), and dibromochloromethane (CHCl 2 Br), chloroform, and bromoform, occurs when chlorine reacts with NOM present in water sources. Other DBPs formed by water chlorination include haloacetic acids (HAAs) and nitrogen-containing DBPs, including haloacetonitriles (HANs), haloacetamides (HAcAs), and dimethylnitrosamine (NDMA), and halogenated aldehydes (HAs) (Table 1).
The identification of chlorine disinfection byproducts in water supplies and dairy products is of significant concern due to their cytotoxic, genotoxic, mutagenic, teratogenic, and endocrine-disrupting potential. The association between trihalomethanes (THMs) and haloacetic acids (HAAs) and tumor formation is documented and has led to the implementation of maximum contaminant levels imposed by the European Union. Furthermore, chlorine resistance in bacterial species is associated with multidrug resistance in clinically relevant pathogens, where antibiotic and biocide resistance genes are also environmental contaminants. Chlorine reacts with organic matter in water to produce approximately 800 disinfection byproducts. Epidemiological studies have demonstrated a correlation between exposure to chlorinated water through ingestion and inhalation and bladder, colon, and rectal cancer, among other health risks. Many of chlorine's disinfection byproducts (DBPs) are potential mutagens and carcinogens in humans and are associated with developmental and reproductive problems, including infertility. The presence of chlorine and DBP residues in dairy products is also concerning, as dairy production relies heavily on chlorine to ensure effective disinfection of food production equipment and facilities. For example, the dairy industry has a high water consumption, with approximately 5,000 L of water used to produce 1 kg of cheese, and cleaning-in-place (CIP) processes rely on chlorinated water supplies. Furthermore, research increasingly highlights the relationship between biocide resistance, AMR, and environmental contamination with ARGs.
The local towns use chlorine, along with fluoride, to 'purify' the water. It would seem those two would likely interact in ways we would not like. Also, it may be likely to use the blue UV light to kill off pathogens and then use filters would be a better way to go.
A very positive proposal, Just. Fluoride is a very reactive ion and can interact with chlorine under certain conditions. For example, in the presence of moisture, chlorine gas can react with fluoride ions to form chlorine fluoride (ClF), a pale yellow, highly reactive, and toxic gas. We know that both chlorine and fluoride can be dangerous.
Chlorine trifluoride is a colorless, toxic, corrosive, and extremely reactive gas used in industrial cleaning and stripping operations in the semiconductor industry, in nuclear reactor fuel processing, and other industrial operations. Reactions with various metals give chlorides and fluorides; with phosphorus, it produces phosphorus trichloride (PCl3) and phosphorus pentafluoride (PF5); and with sulfur, it gives sulfur dichloride (SCl2) and sulfur tetrafluoride (SF4). ClF also reacts explosively with water, oxidizing it to form oxygen or, in controlled amounts, oxygen difluoride (OF), as well as hydrogen fluoride and hydrogen chloride. Metal oxides react to form metal halides and oxygen or oxygen difluoride.
Hypochlorite (ClO₂) is commonly found in treated water. In swimming pools, it is usually introduced as solid calcium hypochlorite. After slowly dissolving in water, it releases a solution containing calcium₂ ions and hypochlorite anions (ClO₂). The anions are oxidizing agents that react with any oxidizable substances present in the water, such as ammonia, bacteria, and pigments. Household bleach is usually a dilute aqueous solution of sodium hypochlorite.
Chlorine can also react with organic matter in the water and form byproducts such as trihalomethanes (THMs) and haloacetic acids (HAAs). Inhaling or ingesting these byproducts can cause respiratory problems, especially in people with preexisting conditions.
Some research has suggested a possible link between prolonged exposure to high levels of THMs and a slightly increased risk of bladder cancer. However, the evidence is still inconclusive, and the risk is considered low.
Reverse osmosis filters are one of the best tools for removing chlorine and fluoride from water.
After filtration, your home's water supply will be free of lead, nitrates, chemicals like chlorine and fluoride, bacteria, radium, volatile organic compounds (VOCs), and others.
