About Environmental Chemistry
Atmospheric pollution includes smog, acid rain, greenhouse gases, ozone depletion and the effects of carbon monoxide, sulfur oxides, nitrogen oxides and particulate matter. Water pollution covers sewage, industrial waste, eutrophication and treatment stages, while green chemistry focuses on reducing hazardous substances, waste and energy use through safer, more efficient processes.
