The VOC Solvents Emissions Directive was the main policy instrument for the reduction of industrial emissions of volatile organic compounds (VOCs) in the European Union. It covers a wide range of solvent-using activities, e.g. printing, surface cleaning, vehicle coating, dry cleaning and manufacture of footwear and pharmaceutical products.
Vehicle emissions control is the study of reducing the emissions produced by motor vehicles, especially internal combustion engines. The primary emissions studied include hydrocarbons, volatile organic compounds, carbon monoxide, carbon dioxide, nitrogen oxides, particulate matter, and sulfur oxides. Starting in the 1950s and 1960s, various ...
The VOCs can also undergo transformation at the surface through interaction with ozone. [43] In both cases, these delayed emissions can result in chronic and low-level exposures to VOCs. [51] Several initiatives aim to reduce indoor air contamination by limiting VOC emissions from products.
Zero-emission buses to replace diesel vehicles and reduce emissions in high-traffic areas. Noise barriers and stricter construction regulations to reduce the impact of traffic and development.
The California Air Resources Board (CARB or ARB) is an agency of the government of California that aims to reduce air pollution.Established in 1967 when then-governor Ronald Reagan signed the Mulford-Carrell Act, combining the Bureau of Air Sanitation and the Motor Vehicle Pollution Control Board, CARB is a department within the cabinet-level California Environmental Protection Agency.
These investments, the Justice Department said, would include technology to reduce benzene emissions by approximately 4.34 tons per year, other hazardous air pollutants by 16.26 tons per year and ...
Selective catalytic reduction. CATALYTIC REDUCTION. Selective catalytic reduction (SCR) means of converting nitrogen oxides, also referred to as NO. x with the aid of a catalyst into diatomic nitrogen (N. 2), and water (H. 2O). A reductant, typically anhydrous ammonia (NH. 3), aqueous ammonia (NH. 4OH), or a urea (CO (NH.
A fluidized bed concentrator ( FBC) is an industrial process for the treatment of exhaust air. The system uses a bed of activated carbon beads to adsorb volatile organic compounds (VOCs) from the exhaust gas. Differently from the fixed-bed or carbon rotor concentrators, the FBC system forces the VOC-laden air through several perforated steel ...
