Emerging technologies can detect, convert, and reduce the pollutants produced and released into the air. The following solutions counter air pollution:
Multi-pollutant monitoring device: Multi-pollutant monitoring device does not remove pollutants or reduce carbon emissions but is an important tool in air pollution management. It detects the presence of more than one pollutant, which enables regulatory bodies' compliance with emission limits for many different pollutants. It also reduces the cost and time required by other ambient monitoring devices.
Catalytic converters: According to government regulations, gasoline and diesel-powered vehicles are equipped with catalytic converters. The resultant pollutants are much less polluting than the original vehicular exhaust.
Scrubbers: Scrubbers remove air pollutants like sulfur dioxide, chlorine, hydrogen sulfide, and hydrogen chloride from industrial exhaust. A scrubber can be either wet or dry. Wet scrubbers absorb gases and particles. Dry scrubbers spray dry reagents into the flue stream that neutralizes the gases before they can enter the atmosphere.
Chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) substitute Products like solvents, propellants, and refrigerants primarily contain these chemicals. The chlorine in CFC and HCFC and its release into the environment depletes the ozone layer. Industries are substituting CFC and HCFC with hydrofluorocarbons (HFC) which lack chlorine.
Stoves and heaters: Stoves and heaters are responsible for 3.8 million deaths due to indoor pollution. Emerging stove designs and alternative fuels reduce the amount of particulate matter in households. Biomass stoves are a better alternative in low- and middle-income countries with high population growth rates. Biomass stoves have secondary combustions, fans, and insulated combustion chambers that burn off unused fuel.
