New Delhi: Pollution occurs when pollutants contaminate the natural environs; which brings about changes that affect our normal lifestyles unfavorably. Pollutants are the key rudiments or mechanism of pollution which are generally waste materials of dissimilar forms. Pollution disturbs our ecosystem and the balance in the environment. With transformation and development in our lives pollution has reached its crest; giving rise to global warming and human illness.
Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal and light. Every form of pollution has two sources of occurrence; the point and the non-point sources. The point sources are easy to identify, monitor and control, whereas the non-point sources are hard to control. But over the past few years pollution is increasing continuously. Industries and traffic are the main cause of it. The PM 2.5 value at 8.32 pm was 184 micro gram per cubic metre, approximately four times the national acceptable limits, calculated by an air monitoring instrument of the Gujarat Pollution Control Board(GPCB) reserved a solitary floor building of the Ahmadabad Municipal Corporation (AMC). Our daily use of vehicles giving rise to various gases like NOx, SOx, ozone, benzene carbon monoxide, toluene and xylene.We daily inhale these gases and these are very much hazardous to our health as these gases enter into blood lungs and various parts and ultimately harms us.
Air monitoring system shows that even the monthly average of particulate matter pollution exceeds perilously both annual and daily allowable limits. However, monitoring data may not be enough for Ahmedabad to embark upon pollution.
Some deadly gases are Ozone, Nitrogen Dioxide, Carbon Monoxide, Sulphur Dioxide etc.
Effects of Pollution:
Environment Degradation: The increase in the amount of CO2 in the atmosphere leads to pollution which can restrict sunlight from reaching the earth. Thus, preventing plants in the process of photosynthesis. Gases like Sulfur dioxide and nitrogen oxide can cause acid rain. Water pollution in terms of Oil spill may lead to death of several wildlife species.
Human Health: The decrease in class of air leads to several respiratory problems including asthma or lung cancer. Chest pain, congestion, throat inflammation, cardiovascular disease, respiratory disease are some of diseases that can be causes by air pollution. Water pollution occurs due to contagion of water and may cause skin related problems.
Infertile Land: Due to constant use of insecticides and pesticides, the soil may become infertile. Plants may not be able to grow properly. Various forms of chemicals produced from industrial waste is released into the flowing water which also affects the quality of soil.
Global Warming: The release of greenhouse gases chiefly CO2 is foremost to global warming. Every other day new industries are being set up, new vehicles approach on roads and trees are cut to make way for new homes. All of them, in direct or indirect way lead to increase in CO2 in the environment. The increase in CO2 leads to melting of polar ice caps which increases the sea level and pose danger for the people living near coastal areas.
