Xenobiotics in the Environment

Xenobiotics are synthetic substances that have found their way into the natural environment in micropollutants and high concentrations. These molecules find widespread use in agriculture, industry, and homes. Their impact on people and the planet is substantial. They can have poisonous, mutagenic, or teratogenic consequences with prolonged exposure to even low quantities. Wastewater treatment plants that do not effectively minimize the discharge of xenobiotics are significant contributors to their presence in the environment. The introduction of these chemicals into the environment can affect both human and animal populations. Creating new synthetic chemicals that align with the naturally occurring catabolic capabilities of microbes could prove to be a more cost-effective strategy, as outlined in this chapter. This approach may help mitigate the future environmental impact of xenobiotics and facilitate the use of chemically modified microbes instead of traditional end-of-pipe technologies.
