How can we reduce SOx emissions?
Since sulfur emissions are proportional to the sulfur content of the fuel an effective means of reducing SOx emissions is to burn low-sulfur fuel such as natural gas low-sulfur oil or low-sulfur coal. Natural gas has the added advantage of emitting no particulate matter when burned.
What effects can stratospheric ozone depletion have on the environment?
Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV) radiation that reaches Earth’s surface which increases the rate of skin cancer eye cataracts and genetic and immune system damage.
What effects can stratospheric ozone depletion have on the environment quizlet?
what are the effects of ozone depletion? The Impacts of Ozone Depletion. Stratospheric ozone filters out most of the sun’s potentially harmful shortwave ultraviolet (UV) radiation. If this ozone becomes depleted then more UV rays will reach the earth.
What are hydrochlorofluorocarbons HCFCs?
Hydrochlorofluorocarbons (HCFCs) are chemical compounds commonly used in the foam refrigeration and air conditioning sectors that destroy the protective ozone layer and contribute to climate change. It is essential to reduce and phase out the use of HCFCs in industry practices.
What natural processes contribute to acid rain?
Natural SourcesSee also what is combinational circuit The major natural causal agent for acid rain is volcanic emissions. Volcanoes emit acid-producing gases to create higher than normal amounts of acid rain or any other form of precipitation such as fog and snow to an extent of affecting vegetation cover and health of residents within the surrounding.
What steps can be taken to reduce pollution due to particulate matter from industries?
Answer : There are many ways to control soil pollution due to industries which includes three R’s principles: Reduce Reuse and Recycle. We can also reduce pollution by proper solid waste management and bioremediation.
What factors decrease air pollution?
If you would like to help reduce air pollution you can take the following measures:
- Eliminate tobacco smoke.
- Reduce your use of wood stoves and fireplaces.
- Don’t burn candles leaves garbage plastic or rubber.
- Use HEPA air filters and air cleaners designed to reduce particles.

What are some natural factors that may help to reduce outdoor air pollution?
1. Three natural factors help reduce outdoor air pollution: rain and snow salty sea spray and winds. Each of these factors helps remove pollutants but they are then deposited elsewhere.
What is likely the most effective way to reduce acid deposition?
What is likely the most effective way to reduce acid deposition? … Implement prevention approaches that reduce or eliminate emissions.
Which of the following forms of air pollution is most directly linked to increased incidence of asthma and bronchitis?
Exposure to ambient concentrations of ozone has been associated with the aggravation of respiratory illnesses such as asthma emphysema and bronchitis leading to increased use of medication absences from school doctor and emergency department visits and hospital admissions.
What are the various mechanisms involved in atmospheric SO2 removal?
Processes such as oxidation wet deposition dry deposition absorption by vegetation and by soil dissolution into water and other processes contribute to the removal of SO2 from the atmosphere. … SO2 is therefore removed from the atmosphere either unchanged or in the form of sulphuric acid and sulphates.
What causes tropospheric ozone?
Tropospheric ozone is formed by the interaction of sunlight particularly ultraviolet light with hydrocarbons and nitrogen oxides which are emitted by automobile tailpipes and smokestacks. … To form ozone needs sunshine to fuel the chemical reaction.

What creates tropospheric ozone?
Tropospheric or ground level ozone is not emitted directly into the air but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC).
Is chlorofluorocarbon a criteria pollutant?
The 1970 Clean Air Act in the United States recognized seven air pollutants as being in immediate need of regulatory monitoring. Pollutants can also damage the atmosphere above Earth’s surface. … A well-known example of this damage is that caused by chlorofluorocarbons (CFCs).
How can we reduce particulate matter?
How can we reduce particle pollution?
- Stop smoking if you do smoke do not smoke indoors.
- Mulch garden refuse instead of burning it.
- Limit the use of fireplaces and wood stoves. When using these appliances make sure that wood is burned properly. …
- Switch to cleaner burning appliances. …
- Take action to reduce wildfires.
Determination of Suspended Particulate Matter (SPM) in Ambient Air.
How is good stratospheric ozone formed?
Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The “ozone layer ” approximately 6 through 30 miles above the Earth’s surface reduces the amount of harmful UV radiation reaching the Earth’s surface.
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 is stratospheric ozone?
Stratospheric ozone is a naturally-occurring gas that filters the sun’s ultraviolet (UV) radiation. … A diminished ozone layer allows more radiation to reach the Earth’s surface. Excessive exposure to UV-B at the surface of the earth has been shown to cause harmful effects in plants and animals.
How is particulate matter released?
Some are emitted directly from a source such as construction sites unpaved roads fields smokestacks or fires. Most particles form in the atmosphere as a result of complex reactions of chemicals such as sulfur dioxide and nitrogen oxides which are pollutants emitted from power plants industries and automobiles.
