A Method forDetermining Source ReductionRequired to Meet Air Quality Standards

Rational establishment of air quality standards.

This paper attempts to apply two principles of rationality--efficiency and equity--to the establishment of air quality standards for total suspended particulates in the USA. It is argued that standard setting should embrace either the use of some cost-benefit-risk criterion, or some concept of equity whereby risks are not reduced below levels judged to be acceptable elsewhere. There is often a ...

a threshold autoregressive asymmetric stochastic volatility strategy to alert of violations of the air quality standards

air quality is a topic of crucial importance, because air pollution is one of the most important pollution problems in the world. in particular, predicting or detecting a future extreme air pollution episode or predicting the violation of an air quality standard, is of crucial interest in the field of pollution control. there have been a variety of attempts to reach this purpose both from the p...

Using SWAT to enhance watershed-based plans to meet numeric water quality standards

The number of states that have adopted numeric nutrient water-quality standards has increased to 23, up from ten in 1998. One state with both stream and reservoir phosphorus (P) numeric water-quality standards is Oklahoma. There were two primary objectives of this research: (1) determine if Oklahoma was meeting the stream and reservoir numeric water-quality standards in the Illinois River and E...

Controlled clinical studies of air pollutant exposure: evaluating scientific information in relation to air quality standards.

In controlled clinical studies, volunteers are deliberately exposed to specific air pollutants under conditions simulating ambient exposures, and health-related responses are documented. Studies of the health risks of air pollution need to be scientifically rigorous and clearly relevant to "real-world" pollution exposures. Their results should be confirmed by independent replication if they are...
