Since indoor air pollutants can adversely affect human health, it is important to have real-time indoor air quality assessment/monitoring system that can help not only in the improvement of indoor air quality but also help in detection of leaks, spills in a work environment and boost energy efficiency of buildings by providing real-time ...
The Clean Air Act requires the EPA to set US National Ambient Air Quality Standards (NAAQS) for the six CAPs. [6] The NAAQS are health based and the EPA sets two types of standards: primary and secondary. The primary standards are designed to protect the health of 'sensitive' populations such as asthmatics, children, and the elderly.
Indoor and outdoor air are sampled, and their mold spore concentrations are compared. Indoor mold concentrations should be less than or equal to outdoor concentrations with similar distributions of species. A predominant difference in species or higher indoor concentrations can indicate poor indoor air quality and a possible health hazard. [8]
OSHA hasn’t even decided yet if new rules are necessary. “I think they should do a better job, better ventilation,” Alarcón said. OSHA Still Undecided on Air Quality Rules Amid COVID
1970 – Clean Air Act (Extension). Major rewrite of CAA, setting National Ambient Air Quality Standards (NAAQS), New Source Performance Standards (NSPS) Hazardous Air Pollutant standards, and auto emissions tailpipe standards. 1970 – Williams-Steiger Occupational Safety and Health Act (created OSHA and NIOSH)
The Air Quality Act of 1967 (Pub. L. 90–148) authorized planning grants to state air pollution control agencies, permitted the creation of interstate air pollution control agencies, and required HEW to define air quality regions and develop technical documentation that would allow states to set ambient air quality and pollution control ...
The standards for determining whether an area is in "attainment" (compliance) or "non-attainment" (non-compliance) for six major pollutants are the National Ambient Air Quality Standards (NAAQS). These are required by law to be reviewed every five years, as new scientific information becomes available on the health and property impacts of ...
A distinction may be made between mandatory and aspirational air quality standards. For example, U.S. state governments must work toward achieving NAAQS, but are not forced to meet them. On the other hand, employers may be required immediately to rectify any violation of OSHA workplace air quality standards.
