National Ambient Air Quality Standards (NAAQS) gets set up by the EPA by the Clean Air Act. The six principle pollutants entail the photochemical oxidants, lead, carbon monoxide, ground-level ozone, sulfur oxides as well as nitrogen oxides. Regulation of surface level ozone reduces the impact and other pollution damages on crops. Likewise, photochemical oxidants prompted particular action from the commission under NAAQS to develop standards that controlled coarse and fine atmospheric particles in the air.
Also, the oxidants had the ability to poison agricultural foods just like lead. Therefore, the optimal level for lead is now at 1.5 mew-grams per cubic meters. Such an environment is fresher compared to the period before the NAAQS. The need to also control the average level of carbon monoxide emission created a new level of environmental standards in 1971. The hazardous Carbon Monoxide decreased by 82% in 1980. However, the outstanding results were as a result of close follow up and keen implementation of the standards. Finally, in the list of the select committee for taking care of the air had to include Sulfur Oxides and Nitrogen Oxides. The two gasses mix with rain water to form corrosive acid rain. However, at regulated quantities, the destructive rain effect is minimal.
