  • A Critical Evaluation of the South African Air Quality Offsets Guideline

    There is wide recognition in South Africa to the link between the quality of life and quality of the air we breathe. The Department of Environmental Affairs (DEA) attempts to improve air quality through two key regulatory tools; emission limits, which regulate the maximum concentration of certain pollutants permissible within certain, ‘listed’ industrial stacks or vents, and ambient ...

  • In the queue for clean air

    The National Emissions Ceilings Directive (NECD), adopted in 2001, defines the maximum emissions on a national level for four major air pollutants that have a high impact on human health and the environment. These are: sulphur dioxide, nitrogen oxides, volatile organic compounds and ammonia. The Directive will undergo revision in 2008, which would set new interim air quality targets and related ...

  • Technology: clean air’s unsung hero

    Last year, we celebrated the 40th anniversary of the U.S. Clean Air Act (CAA) and the 20th anniversary of the 1990 Amendments to the CAA. The CAA has been a huge success. From 1990 to 2008, emissions of six common pollutants were down 41%, while gross domestic product grew 64%. Emissions of volatile organic compounds dropped 31%, carbon monoxide dropped 46%, and sulfur dioxide dropped 51%. Lead ...

  • Particle reduction plans in Europe - Implementation of the first daughter directive on ambient air quality in Europe

    This publication analyses the quality of national implementation of the first Air Quality Daughter Directive (1999/30/EC). The report is based on information from 15 NGOs (members of the EEB’s Clean Air Working Group), who provided data for PM10 concentrations in ambient air as well as information about air quality management plans from 30 cities in Europe. The air pollution challenge Air ...

  • Cleaning & maintenance management

    Mercury is a known neurotoxin that is extremely toxic even in small amounts. It directly affects the central nervous and renal systems, causing developmental delays, motor and brain problems like those associated with autism. Mercury’s hidden danger also lies in when at room temperature and exposed, it vaporizes readily. Once it has become an aerosol, it is absorbed into the lungs and ...

  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...

  • Vinyl Chloride Attenuation By Direct Injection of Time-Release Magnesium Peroxide.

    ABSTRACT: This case study shows that there is potential to remediate dissolved vinyl chloride by oxygenation in the field. Residual vinyl chloride concentrations have been remediated in the field at a mid-western site with a phosphate-intercalated peroxygen (ORC®, a proprietary formulation of magnesium peroxide that releases oxygen slowly). The site was formerly operated as an aluminum coating ...
