Oct 08, 2012 · The first major cause of air pollution is car exhausts which lead to about 45 to 50 % of the total air pollution. It's formed due to the production of unburned fuel in the form of oxides of Nitrogen and hydrocarbons. These black gases produced by unfiltered car exhaust may cause many health problems such as asthma or in extreme causes, could eventually lead to difficulty …
AIR POLLUTION It can be defined as a combination of solid particles and gases in the air. Car emissions, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in the cities. When ozone forms, it is also called air pollution. Air pollution is also referred to as release of pollutants into the air that cause harmful effects to human health and …
Contributors A major contributor to air pollution is us humans. We produce gases that are released into the atmosphere harming it. • Burning of Fossil Fuels; this can vary from burning oils, natural gas, and coal. • Deforestation; this means cleaning out and destroying forest, which messes with the process of cleaning air.
Air pollution continued to be a significant problem up through the middle of the 20th century. In late October of 1948, 20 people were asphyxiated and more than 7,000 became seriously ill as the result of severe air pollution over Donora, Pennsylvania.
But it was in the 1990s that Indian cities started turning into a toxic hell. This deterioration took place despite a spate of strong legislation on pollution control during the 1980s. These include the Air (Prevention and Control of Pollution) Act, 1981 and the Environment (Protection) Act, 1986.Nov 4, 2019
From smog hanging over cities to smoke inside the home, air pollution poses a major threat to health and climate. Ambient air pollution accounts for an estimated 4.2 million deaths per year due to stroke, heart disease, lung cancer, lung cancer, acute and chronic respiratory diseases.
In 1963, the U.S. Congress enacted the first Clean Air Act. Two years later, national emissions standards for cars were set. But it wasn't until the 1970 Clean Air Act that Congress set the framework for air pollution regulation tied to public health.Jan 11, 2016
the London smog3. Which was the first major disaster of air pollution? Explanation: Air pollution became a serious problem in London during the Industrial Revolution. The earliest recorded major disaster was the London smog that occurred in 1952, which resulted in more than 4000 deaths.
The Quelccaya core first records evidence of pollution from Inca metallurgy around 1480 in the form of trace amounts of bismuth, likely released into the atmosphere during the creation of bismuth bronze, an alloy which has been recovered from the Inca citadel at Machu Picchu.Feb 11, 2015
Air pollution and climate change. Burning of fossil fuels, deforestation for agriculture, and industrial activities have pushed up atmospheric CO2 concentrations from 280 parts per million (ppm) 200 years ago, to about 400 ppm today. That's an unprecedented rise, in both size and speed.Oct 11, 2016
The contamination of the natural air with different pollutants, such as fumes and chemicals. Air pollution can cause a range of harmful effects, including increased rain acidity, a plethora of health conditions and a significant contribution to global warming.
Pollution can take many forms: the air we breathe, the water we drink, the soil we use to grow our food, the lit-up skies and even the increasing noise we hear every day can all contribute to health problems and a lower quality of life with major disruptions and effects on wildlife and ecosystems.
The law was amended in 1990 in which modifications and improvements were made to the Clean Air Act. There was the need to reduce acid rain, toxic emissions which could deplete the ozone layer and cause varying respiratory illnesses in humans and to increase visibility.Apr 23, 2021
GO! Air Pollution Analyst (also called Air Quality Field Technician) is a professional scientist that collects, organizes, and examines data from polluted air.
Pollution began to draw major public attention in the United States between the mid-1950s and early 1970s, when Congress passed the Noise Control Act, the Clean Air Act, the Clean Water Act, and the National Environmental Policy Act.

Because a few prominent aspects of indoor air pollution, notably environmental tobacco smoke and "sick building syndrome," have been brought to public attention, individuals may volunteer suggestions of a connection between respiratory or other symptoms and conditions in the home or, especially, the workplace.
The locations of highest concern are those involving prolonged, continuing exposure - that is, the home, school, and workplace. The lung is the most common site of injury by airborne pollutants.
Sources include outdoor air and human occupants who shed viruses and bacteria, animal occupants (insects and other arthropods, mammals) that shed allergens, and indoor surfaces and water reservoirs where fungi and bacteria can grow, such as humidifiers 23. A number of factors allow biological agents to grow and be released into the air. Especially important is high relative humidity, which encourages house dust mite populations to increase and allows fungal growth on damp surfaces. Mite and fungus contamination can be caused by flooding, continually damp carpet (which may occur when carpet is installed on poorly ventilated concrete floors), inadequate exhaust of bathrooms, or kitchen-generated moisture 24. Appliances such as humidifiers, dehumidifiers, air conditioners, and drip pans under cooling coils (as in refrigerators), support the growth of bacteria and fungi.
According to the American Academy of Pediatrics, an estimated three to four million children in the U.S. under age six have blood lead levels that could cause impaired development, and an additional 400,000 fetuses are at similar risk 49.
Wet-mop and wipe furniture frequently to control lead dust. Have professional remove or encapsulate lead containing paint; individuals involved in this and other high exposure activities should use appropriate protective gear and work in well-ventilated areas. Do not burn painted or treated wood.
It is vital that the individual and the health care professional comprise a cooperative diagnostic team in analyzing diurnal and other patterns that may provide clues to a complaint's link with indoor air pollution. A diary or log of symptoms correlated with time and place may prove helpful. If an association between symptoms and events or conditions in the home or workplace is not volunteered by the individual, answers to the following questions may be useful, together with the medical history.
For assistance and guidance in dealing with known or suspected adverse effects of indoor air pollution, contact EPA regional offices, state and local departments of health and environmental quality, and your local American Lung Association Exit (1-800-LUNG-USA).
