Pollution control aims to minimize the release of pollutants into the air, water, and land, thereby protecting human health and the environment.

Primary pollutants are emitted directly from sources such as vehicles, factories, and power plants. Carbon monoxide is a primary pollutant produced by the incomplete combustion of fossil fuels.

Recycling involves the collection and processing of waste materials to transform them into new materials and objects.

Incineration is a waste treatment process that involves burning waste materials at high temperatures to reduce their volume and destroy harmful substances.

Catalytic converters are devices installed in vehicles to convert harmful pollutants, such as nitrogen oxides, into less harmful substances before they are released into the atmosphere.

Reverse osmosis, activated sludge process, and chlorination are all commonly used methods for treating wastewater to remove contaminants and make it suitable for discharge or reuse.

Bioremediation involves the use of microorganisms to break down and remove contaminants from soil and groundwater.

Carbon dioxide is a greenhouse gas that traps heat in the Earth's atmosphere, contributing to the greenhouse effect and global warming.

Waste reduction involves measures taken to minimize the generation of waste at the source, such as using reusable products, reducing packaging, and designing products for durability.

Solar energy, wind energy, and hydropower are all renewable energy sources that do not produce greenhouse gases when generating electricity.

Composting involves the controlled decomposition of organic waste materials, such as food scraps and yard waste, to produce a nutrient-rich soil amendment.

Non-point source pollution comes from diffuse sources, such as agricultural runoff, stormwater runoff, and leaking septic tanks.

Air pollution control involves measures taken to reduce the emission of harmful substances into the air, such as installing pollution control devices on industrial facilities and promoting the use of cleaner energy sources.

Catalytic converters, particulate filters, and oxygen sensors are all devices used in vehicles to reduce emissions of harmful pollutants, such as nitrogen oxides, particulate matter, and carbon monoxide.

Hazardous waste management involves the proper handling, storage, transportation, and disposal of hazardous waste to minimize risks to human health and the environment.
