Halides : understanding the risks and sources of exposure

Abstract

As the world becomes more industrialised, we are constantly exposed to various chemicals in our daily lives. One group of chemicals that have recently come under scrutiny are halides, which are compounds containing halogen elements such as bromide, fluoride, chloride and iodine. Halide ions are a negatively charged, colourless halogen atoms, these are highly soluble in water therefore they are easily found in environmental water bases such as sea, lakes and river. Another unexpected source of halides entails industrial runoffs and running water bedrocks. Halides can be found in a wide range of sources, from everyday household products like cleaning agents and disinfectants to industrial processes like paper production and wastewater treatment. In addition, halides are naturally present in some foods and even in the air we breathe. However, exposure to halides has been linked to a number of health risks, including developmental and reproductive problems, thyroid dysfunction and even cancer. Children and pregnant women are particularly vulnerable to the harmful effects of halides, as their bodies are still developing. It is important for individuals to be aware of the sources of halides in their environment and take steps to minimise their exposure. This can include choosing natural cleaning products, avoiding processed foods with added halides and investing in air and water filtration systems.
