Your question: What chemicals are used in environmental chemistry?

Environmental chemistry also deals with synthetic chemicals that have been manufactured by humans and dispersed into the environment, such as pesticides, polychlorinated biphenyls (PCBs), dioxins, furans , and many others.

What are included in environmental chemistry?

Environmental chemistry is the study of chemical processes that occur in water, air, terrestrial and living environments, and the effects of human activity on them. It includes topics such as astrochemistry, atmospheric chemistry, environmental modelling, geochemistry, marine chemistry and pollution remediation.

What is environmental chemistry used for?

Environmental chemists assess the long-term risks of contaminants in soil and groundwater, both to ecological and human health. They apply for environmental permits to undertake corrective strategies, classify contaminated soils as hazardous waste, manage their disposal, and supervise on-site remediation.

What is the major environmental chemical pollutants?

The main pollutants emitted by these sources are CO2, organic volatiles (VOCs), nitrogen oxides (NOx) and particles of heavy metals such as lead or mercury. The main immobile sources of atmospheric pollution are certain kinds of industrial plant, and power stations or heaters that burn fossil fuels.
