Environmental chemistry delves into the study of chemical reactions transpiring in aquatic, atmospheric, terrestrial, and biological domains, coupled with an exploration of the repercussions induced by human interventions. It encompasses realms like astrochemistry, atmospheric chemistry, environmental modeling, geochemistry, marine chemistry, and strategies for pollution mitigation. This discipline stands distinct from green chemistry, which centers on eradicating pollution at its origin.
At its core, environmental chemistry initiates with comprehending the functioning of unpolluted ecosystems, along with the identification of naturally occurring chemicals, their concentrations, and subsequent impacts. This foundational understanding is imperative for assessing the ramifications of human-induced chemical discharges into the environment.
Within the realm of environmental engineering, pollution control emerges as a collective term for an array of techniques devised to curtail environmental harm stemming from the release of hazardous substances and energies. The aim here is not to cease productive human activities outright, but rather to reconfigure them in a manner where their advantages outweigh their detrimental aftermath.
