To eliminate serious with each passing day air pollution, except clutch processing of pair of air pollution source, reduce what as a result removes matter of certain air pollution to discharge as far as possible besides, still should pass other the government that a series of measure had done pair of air mass works, include formulate and implement policy of policy of executive environmental protection, establish plan of perfect law of environmental protection through legislative measure, strengthen environmental protection management to wait. Standard of formulate air environment is compasses of executive law of environmental protection, the scientific basis that executive air environment manages and method.

　　 (one) the sort of atmosphere environment standard and action

Atmosphere environment standard can divide by its utility for: Content of standard of atmosphere environment quality, air pollution discharges standard, air pollution to control technical standard and standard of air pollution alarm. By its suitable scope can divide for: National level, place standard and occupation standard.

1. Standard of atmosphere environment quality: Standard of atmosphere environment quality is it is main goal in order to ensure human body health and normal living conditions, of some of some main contaminant in providing an atmosphere environment highest allow chroma. It is to undertake air pollution is evaluated, program of prevention and cure of formulate air pollution and air pollution content discharge standard basis, it is the basis that undertakes atmosphere environment manages.

2. Air pollution content discharges a standard: This is with realizing atmosphere environment quality the standard is a target, concessional to polluting a source to emit into atmospheric contaminant content makes limitation, it is the discharge capacity that controls air pollution content and the basis that undertake purifying device is designed, also be environmental management department at the same time execute the law according to. Air pollution content discharges a standard to be able to be divided for national level, place standard and occupation standard.

3. Air pollution controls technical standard: This is a kind of when air pollution content discharges a standard auxiliary regulation. It discharges standard requirement according to air pollution content, use standard of characteristic of combinative production technology, fuel, raw material, purifying device chooses standard, chimney height standard and sanitation to defend take a standard to wait, it is the specific technology provision that achieve pollutant discharge standard to assure and makes from some respect, the purpose is to make production, design and administrator easy master and carry out.

4. Alarm standard: This is atmosphere environment pollution does not send aggravation or develop a tendency according to air pollution, prevent the limiting value of the contaminant content that produce contamination accident and provides. Alarm happens when exceeding this one limiting value, so that take necessary step. The formulate of alarm standard, basically build bear in healthy to human body influence and biology over the integrated research foundation of limit.
