ENVIRONMENTAL IMPACT OF COAL GASIFICATION 1) Toxic Waste Coal is the dirtiest fossil fuel containing many highly toxic materials. The process for the underground gasification of coal (UGC) involves the partial combustion of coal underground. Even more toxic and carcinogenic hydrocarbons, including benzene, toluene, ethylbenzene and xylene is obtained. 2) Waste Disposal Large volumes of highly contaminated water will be produced and the industry has not publicly addressed what will happen to him. The water used to control the process will emerge with other liquids and particles made with the exhaust.
Pollution can come from many sources; point sources or non-point sources including biological contaminants, chemical contaminants or physical contaminants. Heavy metal contamination that can contaminate the environment from the industrial effluents and discharges are classified under chemical contaminants. Industrial effluents can be defined as liquid waste or wastewater produced by reason of production processes by the industries. Heavy metal contamination released from industrial effluent to the environment can cause many consequences to human beings and other living organisms. Heavy metals refer to any metallic chemical element that has a relatively high density and is toxic or poisonous at low concentrations including Mercury (Hg), Lead (Pb), Cadmium (Cd), Chromium (Cr), Copper (Cu), and Zinc (Zn) (Victor 2013).
Environmental pollution is a wide-reaching problem and it is likely to influence the health of human populations in a great way. The affects of environmental pollution in the perspective of air pollution, water and land/ soil waste pollution on human by diseases and problems, animals and trees/ plants. These kinds of pollutions are not only seriously affecting the human by diseases and problems but also the animals and trees/ plants.  One could claim that air pollution started when humans began burning fuels. In other words, all man-made (anthropogenic) emissions into the air can be called air pollution, because they alter the chemical composition of the natural atmosphere.
3.3 Enviromental 3.3.1Short Term This explosion has released radioactive substance to the atmosphere.This radioactive material, have contaminated many areas, Human being,animals and plants. It became directly exposed to the radiation.The radiation is very hazardous which affected the environmental balance. 3.3.2 Long Term The contaminated land, plants and forest has lost it’s quality.It will take long period of time to gain the better quality. 3.4 Physiological 3.4.1Short
It also results in loss of life and both major and minor injuries. Another problem associated with volcanic eruptions is the fumes that are released into the atmosphere. Most volcanoes release gases such as water vapour, sulphur dioxide and carbon dioxide but there are instances when volcanoes release more toxic vapours. These gases are hazardous for people and animals that are downwind of the volcanic eruption. Volcanic eruptions have the ability of changing the climate.
There are many categories of hazardous wastes, each having a negative impact on the ecosystem, more or less, depending on each type of waste. These hazardous waste categories must be known because pre-collecting them is enforced by the law in force and its transgression has drastic sanctions as consequences for endangering the health of the general population and the environment. Here are the most important categories of hazardous waste: • The explosive wastes, capable, under certain conditions, like a spark or a physical shock, to produce an explosion with lethal potential • The oxidising and corrosive wastes, substances which cause strong reactions on a surface level, with disastrous effects for man and
Air pollution can be defined as the presence of gas, liquid or particles contained in the air until the occurrence of a change affecting life or other materials. Air pollution caused by emissions from vehicle exhaust, industrial discharge smoke or pollutants, and the use of charcoal or wood burning fire control. Air pollution can be divided into two parts: primary and secondary. The primary air pollutants began when production of sulfur monoxide and carbon monoxide resulting from incomplete combustion. This process will result in fine particles suspended in the air and give side effects on human health.
Air pollution is a large problem and it is not a problem of people only, the problem of the world also, through such things as global warming and damage to the ozone layer, it has the possible to affect us all. Therefor definitely what is air pollution, what is the cause of this major environmental issue and what can we do about it? This paper is discussing about air pollution. Air Pollution Air pollution is a gas released in a big enough quantity to harmful the health of people or other animals, and it also kill plants or stop the proper growth of plants , damage or disrupt some other condition of the environment for example making buildings crumble), or cause some other kind of nuisance like reduced visibility, perhaps, or an bad odour. We can measure "harmless" or "pollution."
In era globalization, many of people are often faced with the problem of air pollution. Air pollution can be said of the pollution the biggest impact on the environment. Due to the air pollution that causes global warming which lead to the incurrence to natural disasters that threaten our planet. Air pollution is the presence of solid, liquid or gaseous particles in the atmosphere, which are not generally present, or are present in higher concentration and have no beneficial effect. it can be classified into two parts, primary and secondary pollution.
Pollution is the number one contributor to global warming and global contamination. Pollution is a substance or thing that has a harmful or poisonous effect in the environment. There are sub types of water and air pollution. Many pollutants have deadly effects in the environment. Global warming is one of the factors created by pollution and other variants.
