1. Introduction
Air pollution is defined as the presence of any substance in the atmosphere in such a concentration that it may or may tend to be injurious to humans, plants, property and to atmosphere itself. And the substance itself is called air pollutant.
Air pollution occurs due to anthropogenic activities like industrialization, increase in vehicular traffic etc.
Air pollution episodes were rare and highly local with almost no causalities before 1960.
Industrial mishaps are broadly contributing to the air pollutional episodes.
Industrials accidents occur due to lack of safety measures in the industry, poor maintenance of equipment, lack of skilled labour, lack of supervision, negligence etc. The rules for location of industries have to be strictly followed to avoid accidents. The effluents released into the atmosphere from the industries have

The major industrial accidents occur due to gas leakages, mine crash, leakages from nuclear reactors, explosions and fire accidents.
The Bhopal disaster, also known as the ‘Bhopal Gas Tragedy’, was a gas leak incident in India, considered as the world’s worst industrial disaster. This industrial disaster not only causing air pollution, it is also responsible for loss of lives.
On the night of 2-3 December 1984, a poisonous gas named methyl isocyanate leaked from a pesticide plant run by Union Carbide India Ltd., in Bhopal, turning the city into a gas chamber (40 tonnes gas leaked). Thirty years on from the Union Carbide gas leak tragedy, Bhopal is a city defined by the disaster.
On the basis of deaths that took place between 3-6 December 1984 from the leak of MIC gas from the pesticide making factory of Union Carbide India, the State government divided the capital city into two, i.e. area of victims and area not influenced. A total of 62.6% of the population of Bhopal was affected, while the rest was
The facts given in the case of A Cloud in the Midnight Sky raise more questions than they answer. Reviewing this case with the mindset of an administrator, proves to be quite complex. Since I am the acting incident commander, It is my responsibility to declare this situation an external disaster. While the facts in this case study definitely point to catastrophic possibilities, I feel like there are still many pieces of the puzzle that need to be filled. Before I declare a disaster, I need to be in close communication with the local authorities. I will need to assess the entire situation and gather as much information about the incident as possible. Two of the most important pieces of information I would need is what chemical agents if any, have the patients been exposed to and
Rachel Carson was a zoologist, writer, and an ecologist. She recognized the issues which would prove to have deleterious long-term effects. On 27th September 1962, a book which changed the course of the 'environmental movement' was published. It was lauded by supporters who had witnessed the ill-effects of biocides and those who had amassed similar scientific proof. Both Rachel Carson and her publishers had expected a backlash of criticism which unsurprisingly came from chemical industries like Dupont and American Cyanamid. Soon after the book was published, a Dupont initiative 'Union Carbide' single handedly caused the biggest industrial chemical disaster in Bhopal. Major companies like Monsanto led colorful defaming campaigns against the author. The campaign seemed to backfire as the publicity led to increased book sales, and the public awareness rose proportionally. The overwhelming public response had forced the U.S Senate to pay heed to Rachel Carson's views. She presented the scientific data accumulated for the book to President John F. Kennedy and his sub-committee. Their agenda was to formulate policies to counteract the pollution caused by
Chernobyl was the greatest nuclear disaster of the 20th century. On April 26th, 1986, one of four nuclear reactors located in the Soviet Union melted down and contaminated a vast area of Eastern Europe. The meltdown, a result of human error, lapsed safety precautions, and lack of a containment vessel, was barely contained by dropping sand and releasing huge amounts of deadly radioactive isotopes into the atmosphere. The resulting contamination killed or injured hundreds of thousands of people and devastated the environment. The affects of this accident are still being felt today and will be felt for generations to come.
As the Industrial Revolution began, many factories were constructed and along with that, bad air to the environment. Pollution came about and filled up the entire sky with black smoke, as shown on document seven. While the factories produced not only materials but also pollution many people, especially factory workers, got sick and eventually died. Many factory workers got sick due to the enclosed areas that they worked in. Not only that many of the workers were surrounded by massive and dangerous
The other reason is that there are not enough environmental inspectors to cover so many plants in India. Besides, those inspectors have a record of loose enforcement. Consequently, danger emerged just as the saying goes, “Nothing comes of nothing”. As for the management of Union Carbides Bhopal plant, some steps needed to be improved. Let us take a look at the whole process of the gas leak and see what actions can be taken to improve it.
There are many kinds of air pollution. The ones I want to talk about are the ozone, acid rain, carbon monoxide and toxic air contaminants. Ozone is formed when hydrocarbons and nitrogen oxide react in sunlight. Therefore, ozone is at its peak during hot summer days. Exposure to high levels of ozone can have serious consequences on your health. It can cause respiratory disease, loss of pulmonary elasticity, and premature aging of our lungs. Next, is acid rain, which occurs in the atmosphere in the form of sulfur and nitrogen oxide. These pollutants can have serious damaging affects on aquatic, forest and wildlife ecosystems, as well as deterioration of buildings. Carbon monoxide is another form of pollution. It reduces the blood?s ability to carry oxygen. If a human is exposed to higher levels, it can cause chest pains, angina attacks or even death.
During the winter of 1952-1953, London came face to face with the “heaviest winter smog episode known to men.” (Environmental disasters) During the weeks leading to this even London had been experiencing colder than usual weather. Because of the cold weather, households were burning more coal to keep their families warm. This caused “additional coal combustion and many people travelled only by car, which caused the occurrence of a combination of black soot, sticky particles of tar and gaseous sulphur dioxide.” (Environmental disasters) During this event the numbers of deaths per day increased to a nine times the normal number in some cities. The smog approximately killed 12,000 people. Most of the victims were children and elderly people.
The accidents involving machinery kill and/or hurt more coal miners in a year than any other mining accident. The machinery in mines are located in cramped spaces with little light, causing miners to have two times the chance of accidents. The accidents involving roof and rib failures can usually be averted if a mining company has a roof support plan. For a roof support plan to be made, information like entry widths, mine geometry, the number of pillars that must be left up right, and the number of bolts that must be used are needed (Cobb 3 of 5) Accumulations of gases in underground coal mines is another very serious hazard. If certain gases like methane and carbon monoxide are at or above 5% in the air they can cause violent explosions. Blasting in coal mines are the main cause for such dangerous levels of carbon monoxide.
Until 10 years ago, air pollution was thought to be just an urban or local problem until it was discovered that the pollutants could move across continents and oceans. Air pollution is the fundamental factor that causes greenhouse gases, hence climate change and global warming. Air pollutants are the waste products generated from industrial and other processes. They usually come in gases, though aerosols (particles suspended in air, emitted as or formed by transformatio...
Every year, more than sixty-six million tons of poisonous gas is emptied into the air,
Air pollution according to the Wikipedia << is the introduction of particulates, biological materials, or other harmful materials into the Earth’s atmosphere, possibly causing disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment>>. Therefore, human being should be aware of the facts that the environment and all living creatures are dying. They need to understand the importance of natural items, the nature, etc…
Air pollution is when a poisonous or harmful substance is released into the air. There are many forms of pollution but air is one of them, it only occurs when dust, harmful gases or smoke enters into the atmosphere and makes it hard for species like plants, animals and humans to live in a difficult situation because of the dirty air. Air Pollution is classified in two sections, invisible air pollution and visible air pollution.. Hence any substance that makes it difficult for the living things that need the atmosphere is air pollution. Humans have been undergoing air pollution ever since the industrial revolution.
Chemical and fire hazards in the workplace cause serious injuries that in most cases are fatal.
Air pollution is a type of pollution that can severely damage our environment as well as the earth’s atmosphere. Air pollution occurs all the time when the air contains many substances ...
In the early 1900s industrial accidents were commonplace in this country; for example, in 1907 over 3,200 people were killed in mining accidents. At this time legislation and public opinion all favored management. There were few protections for the worker's safety. Today's industrial employees are better off than their colleagues in the past. Their chances of being killed in an industrial accident are less than half of that of their predecessors of 60 years ago. According to National safety Council (NSC), the current death rate from work-related injuries is approximately 4 per 100,000, or less than a third of the rate of 50 years ago. Improvements in safety up to now have been the result of pressure for legislation to promote health and safety, the steadily increasing cost associated with accidents and injuries, and the professionalization of safety as an occupation. When the industrial sector began to grow in the United States, hazardous working conditions were commonplace. Following the Civil War, the seeds of the safety movement were sown in this country. Factory inspection was introduced in Massachusetts in 1867. In 1868 the first barrier safeguard was patented. In 1869 the Pennsylvania legislature passed a mine safety law requiring two exits from all mines. The Bureau of Labor Statistics (BLS) was established in 1869 to study industrial accidents and report pertinent information about hose accidents. The following decade saw little progress in the safety movement until 1877, when the Massachusetts legislature passed a law requiring safeguards for hazardous machinery. In 1877 the Employers' Liability Law was passed. In 1892, the first safety program was established in a steel plant in Illinois, in response to the explosion of a flywheel in that company.
