Whether emanating from vehicles, houses or work sites, air pollution costs considerable resources to regulate. Growing concerns over the environment, from greenhouse gases to long-term carcinogens in the water table, turn up the wattage on the spotlight already cast on industry. Lower your risk of violating regulations and reduce operating costs by keeping abreast of the latest air-pollution control equipment and technology. The terms below outline the main air-pollutant categories and the major methods you can use to fight them.
Particulate matterThat cloud of black smoke bellowing from a diesel exhaust stack is comprised of particulate particles, one micron or smaller, that float in the air, damaging air quality and causing health problems.
Hazardous air pollutants and volatile organic compoundsAlso called toxic air pollutants or air toxics, hazardous air pollutants (HAP) are chemical compounds known to cause health problems including cancer. Most frequently a byproduct of paint and pharmaceutical industries, volatile organic compounds (VOC) are chemical compounds that, due to their high pressure and low water solubility, can be difficult to remove from the manufacturing process; as such, they commonly infiltrate and contaminate groundwater.
