CHAPTER 6 . ENVIRONMENTAL IMPACT ANALYSIS 6.1. Impacts of Environmental pollution: Various impacts of environmental pollutions are listed below. a. Emissions from natural gas combustion and raw cement burning can cause negative effects on public health and lead to degradation of the surrounding environment.
We should promote such a farming where there is no harm to the environment. Today, in most industrial agriculture, there is excessive use of chemical fertilizer and insecticides. Though many types of pollutants are responsible for destroying the fertility of the land, excessive use of chemical fertilizers is one of the main reasons. In chemical fertilizers, phosphate, nitrogen and other chemicals are polluting the environment and groundwater resources of land. The most dangerous pollutants are bioactive chemicals, due to which the micro-organisms of climate and soil are being destroyed resulting in decreased quality of soil.
air pollution is dangerous to the way we live because it’s harmful chemicals that are oils gasses and other chemicals. air pollution is controversial because people believe that it’s still out there harming the way we live and harming the planet. Industrialized countries have worked to reduce levels of sulfur dioxide, smog, and smoke in order to improve people's health. Volcanic eruptions from volcanos is also endangering the life style by balking the sun and putting out ash and smoke. Pollution released into the air damages the ozone layer in Earth’s atmosphere.
1 INTRODUCTION Environmental pollution is one of the worldwide growing threats to human health and natural resources. One major cause of environmental degradation is air pollution due to natural and manmade sources. The main impacts of air contaminants include ground- level ozone, acid rains, greenhouse effect, climate change, ozone layer depletion and adverse health hazards. Benzene and toluene are organic compounds found in indoor air as a result of emissions from burning coal and oil, some household products which contain petroleum based chemicals like glues, paints, etc. Outdoor sources are like gasoline vapors at gasoline service stations, motor vehicle exhaust, emissions from industrial sources utilizing benzene and toluene, etc.
Primary pollutants are particles that are pumped into the air making it filthy and unclean. In the other hand, secondary pollutants are when pollutants get mixed up in a chemical reaction in the air. Forming a more hazardous chemical. An example of a secondary pollutant is a photochemical smog. Air pollution mainly happens when gases unload from industry and vehicles.
The problem of soil pollution arises due to mixing of toxic, and polluted materials in the soil. Illegal dumping is the biggest reason for soil pollution, which adversely affects the quality of soil and the health of people living on it. Soil pollution also spreads through polluted water absorbed by the soil. Chemical compost used in agricultural work also badly pollutes the soil. Litter and dirt also pollute the soil.
For example, the excess greenhouse gas traps heat resulting in global warming, in turn, impacting the environment and humans breathing in the pollution causes health problems such as lung cancer or asthma. Air pollution proves to be a serious problem, one in which humans created but refuse to acknowledge, forcing us to deal with the consequences if not taken care of. We, as a global society, must conscientiously control the amount of fossil fuels burned to protect the atmosphere because it affects the rest of the world. No matter where the pollution is created or what caused it, society must monitor toxic emissions because the contamination affects the globe as a whole in the form of climate change. If one country creates pollution the effects are felt around the world due to the rising temperatures of global warming.
Our world becoming ugly because of environmental pollution. Pollution can also cause various health problems and other affects living creatures. If the pollution increases, animal species will be reduced even going extinct. We have to find solution this problem for our children. Firstly, air pollution is caused by the emission of toxic gases from cars, factories and open burning.
Sulphur dioxide that makes air toxic is produced by the burning of coal in everyday normal activities that make the smoke produced by factories, cars and of burning wood. Abnormalities like global warming and acid rain are caused by the release of carbon dioxide and other harmful gases to the air. This is not only causing environmental degradation but it also has a huge effect of the human health. It can cause a noticeable increase in respiratory problems like asthma and lung cancer. By breathing contaminated air,
TOXICOLOGY OF AIR POLLUTION Effects of air pollutants on living organism will not only be limited to the human and animal health but also include the whole environment. Different geographical conditions, global climate changes, and the environmental variations affect the human health and the environment including the animal life. ENVIRONMENTAL DAMAGES Ecologically, air pollution can cause serious environmental damages to the groundwater, soil, and air. It is also a serious threat to the diversity of life. Studies on the relationship between air pollution and reducing species diversity clearly show the detrimental effects of environmental contaminants on the extinction of animals and plants species.
