Current Approaches for National Ambient Water-Quality Criteria for Aquatic Life Protection in the NetherlandsApproachesCriteriaNetherlandsThis section presents a summary of the methodology to derive national AWQC and in the Netherlands. In the first section, the terminology and framework arepresented. In ...
The EPA Office of Air Quality Planning and Standards (OAQPS) has set National Ambient Air Quality Standards for six principal pollutants, which are called criteria pollutants. They are listed below. Units of measure for the standards are parts per million (ppm) by volume, parts per billion (...

Achievement of national climate targets and the corresponding costs would entirely depend on regional actions within the country. However, because of substantial inequalities and heterogeneities among regions, especially in developing economies, aggressi
The dominant type was baseline water, which had low TDS, low CO2, and an ambient temperature typical of shallow groundwater, along with short flow paths from topographically driven local flow systems in crystalline bedrocks. Alkaline mineral water occurred in carbonate rocks and to a lesser ...
Secondly, the decision to establish high-tech zones is primarily based on local economic development or industrial restructuring considerations, not directly linked to urban air quality, meeting the criteria for selecting instrumental variables. The regression results using instrumental variables, presented ...
(2035 or 2050). As a benchmark, the US Environmental Protection Agency’s National Ambient Air Quality Standard for annual average secondary PM2.5concentration is 15 µg/m[3 45. While the levels in our simulation (around 1 µg/m3) are lower than this standard, we note that ...
The U.S. air quality management system is a cyclical process driven by the goals of meeting national ambient air quality standards (NAAQS) (Bachmann, 2007; NRC, 2004). NAAQS are set by the U.S. Environmental Protection Agency (EPA) for six criteria pollutants, including fine particulate matt...
