Tropospheric pollution

What causes tropospheric ozone? Is pollution in the troposphere? How does ozone cause air pollution? How to reduce ground level ozone? Pollution is the introduction of contaminants into the natural environment that cause adverse change.

Pollution can take the form of chemical substances or energy, such as noise, heat or light. Tropospheric air pollution has impacts on scales ranging from local to global. Ozone is least concentrated in the ground layer (or planetary boundary layer) of the troposphere.

Ground level or tropospheric ozone is created by chemical reactions between oxides of nitrogen (NOx gases) and volatile organic compounds (VOCs). The combination of these chemicals in the presence of sunlight form ozone. Oxides of sulphur, nitrogen, carbon, and hydrocarbons are the major gaseous pollutants.

These oxides react with water in the presence of atmospheric oxygen to form nitric acid (HNO3) and sulphuric acid (H2SO4), which leads to the formation of. The major gaseous and particulate pollutants present in the troposphere are (i) Gaseous air pollutants: These are oxides of sulphur, nitrogen and carbon, hydrogen sulphide, hydrocarbons, ozone and other oxidants. Known as tropospheric or ground-level ozone, this gas is harmful to human heath and the environment.

Since it forms from emissions of volatile organic compounds (VOCs) and nitrogen oxides (NOx), these pollutants are regulated under air quality standards. In the US, plants that are easily affected by ozone air pollution include black cherry, white pine, and red alder. Ozone can interfere with the process of photosynthesis and damage leaves hence plants cannot produce and store food. Europe, show a marked increase in tropospheric ozone in the northern hemisphere.

Stratospheric Pollution. The upper stratosphere consists of considerable amount of ozone (O ), which protects us from the harmful ultraviolet (UV) radiations coming from the sun. These radiations cause skin cancer in humans.

In urban areas, high ozone levels usually occur during warm summer months. NOx and VOCs are called ozone precursors. Motor vehicle exhaust, industrial emissions,.

Automobile exhaust and industrial emissions release a family of nitrogen oxide gases (NOx) and volatile organic compounds (VOC), by-products of burning gasoline and coal. NASA satellite sensor to keep tabs on pollution NOx is a product of fuel combustion that contributes to the formation of smog, acid rain, and tropospheric ozone, which is commonly known as bad ozone. NOx reacts with ammonia, moisture, and other compounds to form nitric acid and related particles. Human health concerns include effects on breathing and the respiratory system, damage to lung tissue, and premature death. Troposheric, or ground-level ozone, is the major ingredient in smog and continues to pose a health risk to many Americans.

As a direct greenhouse gas, it is thought to have caused around one third of all the direct greenhouse gas induced warming seen since the industrial revolution. Waste dumping and burning top polluting activities’ The major polluting activity in the city is open waste dumping and it is also the major polluting source identified in NCR, along with open burning of waste. Given these uncertainties, projections suggest that climate change will increase concentrations of tropospheric ozone,.

Ozone (O ) in troposphere is the most critical secondary air pollutant, and being phytotoxic causes substantial losses to agricultural productivity.
