POLLUTANTSThis work presents a year-long integral study of air quality parameters in Ciudad Real, a small city in the center of Spain, and its influence on the nearby national park, Las Tablas de Daimiel. The study covers meteorological parameters and criteria pollutants such as O3, NO, NO2...
(O3). DEFRA reports air quality levels combining these different pollutants using a specific UK air quality index, called the ‘Daily Air Quality Index’ (DAQI). The DAQI bands air quality levels along a scale of 1-10, which corresponds to different health hazard warning related to air ...

Interestingly, not all criteria pollutants showed decrease to same extent and rather some still stayed above the National Ambient Air Quality Standard (NAAQS) values over New Delhi, the national capital of India. As the restrictions eased out in LD 3 and LD 4, pollution levels started increasing...
Environmental Protection Agency (EPA) as “criteria” pollutants—criteria meaning that the concentrations of these pollutants in the atmosphere are useful as indicators of overall air quality. The sources, acceptable concentrations, and effects of the criteria pollutants are summarized in the table. ...
Standards for the six criteria air pollutants were established by the U.S. Environmental Protection Agency (EPA) to protect public health and the environment. The pollutants are sulfur dioxide, nitrogen dioxide, particulate matter, carbon monoxide, ozone
Environmental effects of air pollution: Implications for air quality criteria, air quality standards and emission standardsA review is given of the effects of air pollution on the environment, and of the influence of environmental factors on concentrations of air pollutants. The emphasis is on ...
Many different types of gases, solid particulates, and liquid droplets can mix with the air and affect air quality. These pollutants can come from both natural and synthetic sources. Monitoring Air Quality in Homes and Workshops "This air monitor is part of a larger effort by the United States...
EPA's roll in the quality assurance of monitoring data is to assist monitoring agencies by providing those quality-assurance services or functions that (1) are common to most monitoring agencies and would be uneconomical to duplicate in each agency's program, (2) are too costly for individual ...
Of the six criteria pollutants for which National Ambient Air Quality Standards (NAAQS) have been established in the U.S., ozone has been the most difficul... TY Chang,DP Chock,RH Hammerle,... - 《C R C Critical Reviews in Environmental Control》 被引量: 33发表: 1992年 Energy and a...
