What actions could we take to decrease so2 and NOX?
Reducing Pollution
Scientists have found different ways to reduce the amount of sulfur dioxide released from coal-burning power plants. One option is to use coal that contains less sulfur. Another option is to “wash” the coal to remove some of the sulfur.
What factors that are causing sea level to rise Choose all that apply?
Sea level rise at specific locations may be more or less than the global average due to many local factors: subsidence upstream flood control erosion regional ocean currents variations in land height and whether the land is still rebounding from the compressive weight of Ice Age glaciers.

Which method is used to remove particulate matter present in exhaust of thermal power plant?
What led to the Clean Air Act of 1970?
Dense visible smog in many of the nation’s cities and industrial centers helped to prompt passage of the 1970 legislation at the height of the national environmental movement.
What was the major improvement to air quality contributed by the 1990 amendments to the Clean Air Act?
Clean Air Act programs have lowered levels of six common pollutants — particles ozone lead carbon monoxide nitrogen dioxide and sulfur dioxide — as well as numerous toxic pollutants. Between 1970 and 2020 the combined emissions of the six common pollutants (PM2.
Which factor is a major contributor to outdoor air pollution?
The common sources of outdoor air pollution are emissions caused by combustion processes from motor vehicles solid fuel burning and industry. Other pollution sources include smoke from bushfires windblown dust and biogenic emissions from vegetation (pollen and mould spores).
Who pushed for the Clean Air Act?
The Clean Air Act was signed by President Richard Nixon on December 31 1970 to foster the growth of a strong American economy and industry while improving human health and the environment.
Why was the Clean Air Act 1963 created?
What are the six criteria pollutants in the original Clean Air Act Why were they chosen?
1) Sulfur Dioxide 2) Nitrogen Oxides 3) Carbon Monoxide 4) Ozone (and its precursor volatile organic compounds) 5) Lead 6) Particulate Matter These six are referred to as conventional or criteria pollutants and they were addressed first because they contributed to the largest volume of air quality degradation and are …
