Soil Infertility Due to The Improper Disposal of Radioactive Waste This article throws light upon the two natural sources of radioactive pollution. The sources are: (i) Extra-Terrestrial Radiations or Solar Radiations, and (ii) Terrestrial or Environmental Radiation. The extra-terrestrial natural radiations come from outer space and hence they are called as cosmic rays or solar radiation. Radioactive material causes radioactive pollution so it is necessary to handle radioactive material with utmost care and concern. Radioactive materials are those materials or elements that emit radiation, thus they are not stable and get transformed into other radioactive or non-radioactive materials. More information: Jinqiang Zhang et al, Deep stratospheric intrusion and Russian wildfire induce enhanced tropospheric ozone pollution over the … A key cause of radioactive pollution is breaches at nuclear power plants, which can result in leakages of radioactive matter into the environment. Another cause is chemical spills. The following is a list of causes of air pollution that is not exhaustive by any means: 1. When the level of these organic and inorganic compound exceeds the level of natural limit due to soil microbial activity, decomposition of organisms and wind activity leads to soil pollution. In fact, some pollution is natural. Killing certain enzymes in the body can simply make you sick. But greenhouse gas is something that is at the top of that list. What Causes Radioactive Pollution? Everything has pros & cons, and thus technology also has its pros & cons. Thermal pollution 6. However, trash and chemicals can get thrown into the ocean and lakes. Radio-isotopes. We need refined oil to run our vehicles. 4. Terrestrial radiation is caused by natural radionuclides in the earth's crust. Air pollution is not a new process but many natural causes like eruption of volcano, mixing of soil particles in the air by strong winds or wildfire have been happening since ancient times. radiation pollution causes and effects pdf ... temperature of a natural body of water which may be.of pollution, their effects on our environment and the various measures that can be taken to control such. Background radiation is emitted from both naturally occurring and man-made sources. Natural sources include cosmic radiation, radon, radiation in the body, solar radiation and external terrestrial radiation. Man-made forms of radiation are used in X-rays, cancer treatment, nuclear facilities and nuclear weapons. Air pollution produced by humans can be due to-• Smoke emanating from vehicles, deforestation, combustion of wood, coal, cow dung … Nuclear weapons testing- Beginning with the Second World War when Japan was subdued after the use of the nuclear bombs on the cities of Hiroshima and Nagasaki, countries have been in the race to develop their own nuclear arms, in the name of defence, but more to threaten rival nations. Lead causes lead poisoning (Lead interferes with a variety of body processes and is toxic to many organs and tissues). Natural crises lead to humanitarian catastrophes all over the world. Excessive Agricultural & Farming ActivitiesThe agricultural industry, yielding into the rising demand for food, increases the use of synthetic fertilisers and… ), the most common ones that can pose moderate to serious health risks include: Radon is naturally in the atmosphere in trace amounts. Natural sources are be dust storms, volcanic eruptions and emissions from plants. It is always a great idea to be informed about water pollution and its sources and causes. Natural disasters are bad enough by themselves. Environmental Pollution not only affects life of flora and fauna but also affects the economy of a country. The radiation pollution is the increase of the amount of radiation in the environment, The sources of radiation pollution are natural sources and artificial sources, Natural sources are represented by natural radioactive materials found on the Earth’s surface (the radioactive elements) and the cosmic radiation that comes from the outer space. However, the sublethal effects of UV-B on developing amphibian embryos in nature are unknown. Milankovitch cycles over the past 1 000 000 years. Check out our article: What is Water Pollution? Bruce Ames and Lois Swirsky Gold have come to similar conclusions, noting that smok-ing causes about a third of all cancers.2 They 2. Indeed, recent evidence suggests that ambient UV-B (280–315 nm) radiation, perhaps linked to stratospheric ozone depletion or pollution ( 8 – 12 ), causes significant embryonic mortality in some amphibian species ( 13 – 15 ). Radiation that produces light in order for photosynthesis to occur is a positive effect that radiation has on plant life 3. Natural causes of climate change. ... Milankovitch proposed that glacial periods began when the three cycles align to favor an extended period of more solar radiation in the winter and less solar radiation in the summer at a latitude of 65°N. It is the type of air pollution sources that is definitely one of the most harmful gases out there. However, the amount of air pollution caused by natural causes is minuscule when compared to the damage done by man-made causes. In particular, a specific type of pollutant called particulate matter, which is in diesel and petrol exhaust fumes (and tobacco smoke), has been shown to increase the risk of cancer, especially lung cancer. Air Pollution Essay: The rising concentration of the corrosive and toxic substances in the fresh air of the environment is generating air pollution. They then eject that water back into the natural resource, which changes the oxygen levels and can have disastrous effects on local ecosystems and communities. Everything you wanted to know about our changing climate but were too afraid to ask. The gases like chlorofluorocarbons, bromine monoxide, chlorine monoxide, halons etc used in the refrigerators, coolers, foam industries, fire extinguishers and other industrial work s deplete the ozone layer. It can mean x-rays, or it can mean microwaves. including UV radiation, temperature, and abrasion, and as a result may take hundreds of years to decompose. Whether it is natural or human made (such as nuclear power stations), radiation causes problems in humans as well as in ecosystems. Since the radiation targets the genetic material therefore the defects caused are transmitted from parents to offspring. You only have to turn on the TV, or search the Internet to see the latest victims of a hurricane or an earthquake. 4 of 10 Humans need water to survive. The majority of background radiation occurs naturally from minerals and a small fraction comes from man-made elements. 4. Examples of Water Pollutants [4 Answers] October 29, 2018. Pollution is a harmful contamination of natural resources.There are predominantly 9 types of pollution like 1. Air Pollution. Air pollution is one of the biggest challenges of present humanity. Most radon exposure occurs inside homes, schools and workplaces. The ozone is primarily created at tropical latitudes large-scale air circulation patterns in the lower stratosphere move ozone toward the poles, where the concentration of the ozone … Natural Causes of Climate Change. Air pollution means the presence of any abnormal material or property in the air that reduce the usefulness of the air resources. Air pollution means … Environmental pollution is defined as "the introduction of contaminated substances in the natural environment", which has harmful or toxic effects and causes adverse changes.
