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.
ISO 22000 is the most popular voluntary food safety international standard in the food industry with 51,535 total number of sites (as per the ISO Survey 2022).The ISO 22000 family are international voluntary consensus standards which align to Good Standardization Practices (GSP) [3] and the World Trade Organization (WTO) Principles for the Development of International Standards.

NSF International, originally named the National Sanitation Foundation (NSF), was founded in 1944 by the University of Michigan School of Public Health, in an attempt to standardize requirements around sanitation and food safety. [1] The first standards developed by the NSF set sanitation requirements on soda fountain and luncheonette equipment.
As an example, the United States Environmental Protection Agency has developed the National Ambient Air Quality Standards (NAAQS) [6] NAAQS set attainment thresholds for sulfur dioxide, particulate matter (PM 10 and PM 2.5), carbon monoxide, ozone, nitrogen oxides NO x, and lead (Pb) in outdoor air throughout the United States.
For sulfur dioxide (SO 2), the guidelines stipulate concentrations not exceeding 40 μg/m 3 24-hour mean. [2] For carbon monoxide concentrations not exceeding 4 mg/m 3 24-hour mean. [2] Up to 30 % of Europeans living in cities are exposed to air pollutant levels exceeding EU air quality standards.
The standards have been updated several times since 1970. [3] The six criteria pollutants in particular are tracked due to their known harmful effects on human health and the environment. [ 1 ] An area with outdoor air exceeding the limit for a given pollutant is considered a non-attainment area for that pollutant.
Sanitation scores and their corresponding letter grades are used in North Carolina to assess restaurants’ adherence to rules and standards intended to mitigate and prevent the spread of ...
The gas used is usually inert, or of a nature that protects the integrity of the packaged goods, inhibiting unwanted chemical reactions such as food spoilage or oxidation. Some may also serve as a propellant for aerosol sprays like cans of whipped cream. For packaging food, the use of various gases is approved by regulatory organisations. [1]
