This phenomenon arises from the high electronegativity of halogens, which enhances chemical stability and, as a result, increases resistance to degradation. Organic compounds that contain halogens exhibit greater hydrophobicity and are often more toxic.
When compared to hydrogen, chlorine atoms form stronger and more stable bonds with carbon. Replacing hydrogen with chlorine in organic compounds results in the creation of more resilient carbon-chlorine bonds, making the molecules less reactive and more stable. The increased stability of these bonds reduces the vulnerability of chlorinated organic compounds to environmental degradation.
Chlorinated organic compounds typically show lower reactivity when exposed to common environmental factors such as oxygen, sunlight, and various reactive chemical species (Nikel et al., 2013). This diminished reactivity protects chlorinated compounds from chemical transformations and degradation, contributing to their persistence in the environment. Many microorganisms that usually break down chlorinated compounds struggle to cleave carbon-chlorine bonds, which further limits the biodegradability of these compounds and extends their duration in natural ecosystems.
Chlorination processes can produce stable and persistent chlorinated by-products that hinder their own breakdown, thus reinforcing the stability and longevity of the chlorinated compounds. The accumulation of such by-products further enhances the environmental resistance of these organic substances. While this stability can be beneficial in certain industrial applications, it also contributes to their extended presence in the environment and raises potential risks to ecological and human health, especially when chlorinated compounds are released into the surroundings.
