You were introduced to wastes and pollutants in Study Session 1, where we discussed the interactions between humans and our environment. Pollution was defined as the introduction into the environment of substances liable to cause harm to humans and other living organisms. Many human activities pollute our environment, adversely affecting the water we drink, the air we breathe, and the soil in which we grow food.

This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge.
NCBI Bookshelf. Disease Control Priorities in Developing Countries. Environmental pollution has many facets, and the resultant health risks include diseases in almost all organ systems. Thus, a chapter on air and water pollution control links with chapters on, for instance, diarrheal diseases chapter 19 , respiratory diseases in children and adults chapters 25 and 35 , cancers chapter 29 , neurological disorders chapter 32 , and cardiovascular disease chapter 33 , as well as with a number of chapters dealing with health care issues. Each pollutant has its own health risk profile, which makes summarizing all relevant information into a short chapter difficult.
Pollution , also called environmental pollution , the addition of any substance solid , liquid , or gas or any form of energy such as heat , sound, or radioactivity to the environment at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. The major kinds of pollution, usually classified by environment, are air pollution , water pollution , and land pollution. Modern society is also concerned about specific types of pollutants, such as noise pollution , light pollution , and plastic pollution. Pollution of all kinds can have negative effects on the environment and wildlife and often impacts human health and well-being. Pollution occurs when an amount of any substance or any form of energy is put into the environment at a rate faster than it can be dispersed or safely stored. The term pollution can refer to both artificial and natural materials that are created, consumed, and discarded in an unsustainable manner. Air pollution , water pollution , and land pollution are three major forms of environmental pollution.
What is Air Pollution?
Sikkim is a small Indian State known for its clean and green image. Amidst several economic and infrastructural developments taking place in the State, Sikkim has amicably sustained its natural resources with hosts of environment amelioration initatives. The Government of Sikkim has imposed ban on use of firecrackers, prohibited burning of agricultural waste, banned the use of styrofoam products, banned burning of tyres, banned use of polythene carrybags and chemical fertilizers. Sikkim has hosts of flagship programmes like State Green Mission, Ten Minutes to Earth, Smritivan and Paryavaran Mahotsav programmes which has greatly mobilised the entire state's populace in plantation and cleanliness activities throughout the State. Sikkim is now known as one the cleanest State of the country and boast of Gangtok, its capital town being declared as the Cleanest Hill Station and Cleanest Town of the country. For the clean and green image, Sikkim has also been rated as amongst the top tourist destinations of the World. Notifications [ PDF].
Air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. Read here more about 40 facts of air pollution. Another way of looking at air pollution could be any substance that holds the potential to hinder the atmosphere or the well being of the living beings surviving in it. The sustainment of all things living is due to a combination of gases that collectively form the atmosphere; the imbalance caused by the increase or decrease in the percentage of these gases can be harmful to survival. Global warming , a direct result of the increased imbalance of gases in the atmosphere, has come to be known as the biggest threat and challenge that the contemporary world has to overcome in a bid for survival.
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution is often classed as point source or nonpoint source pollution. In , pollution killed 9 million people worldwide. Major forms of pollution include air pollution , light pollution , litter , noise pollution , plastic pollution , soil contamination , radioactive contamination , thermal pollution , visual pollution , and water pollution. Air pollution has always accompanied civilizations. Pollution started from prehistoric times , when man created the first fires. According to a article in the journal Science, " soot " found on ceilings of prehistoric caves provides ample evidence of the high levels of pollution that was associated with inadequate ventilation of open fires.
Study Session 7 Pollution: Types, Sources and Characteristics
The planet keeps nudging us with increasingly extreme droughts, reminding us that water is life. It is an essential resource upon which all living beings depend and it is crucial to all social and economic development, as well as energy production and adaptation to climate change. Nevertheless, we are now facing a gigantic challenge.
Давайте же, ребята.
