Explanation
The Kyshtym accident occurred in plutonium production site in Russia on 29 September 1957. It occurred due to uncontrolled heating of the radioactive liquid waste. Windscale fire accident occurred in 1957 in England in the nuclear reactor facility. The graphite reactor lost its coolant and as a result, the adjacent uranium cartridge started heating up. The leakage of the radioactive waves caused a massive fire incident that took almost 16 hours to control.
A. Windscale accident occurred on 10 October 1957.
B. The Church Rock Uranium mill accident occurred in 1979.
C. The Three Mile accident occurred in 1979.
D. The Kyshtym accident occurred on 29 September 1957
Svante Arrhenius, a Swedish scientist, in 1896 gave the theory related to the effects of the combustion-released carbon dioxide. He depicted the relation between the concentration of the carbon dioxide and the increase in temperature due to it. The greenhouse effect refers to the trapping of the infra-red rays reflected by the earth’s surface by the gases present in the troposphere. It is a natural process and is responsible for maintaining the survivable temperature in earth. However, anthropogenic release of the greenhouse gases has caused the events of global warming. Hence, the correct answer is 'Svante Arrhenius'.
Air pollution is caused by the release of harmful oxides of nitrogen, sulphur and carbon from the vehicular exhausts and industrial emissions primarily. Using precipitators allow the removal of dust from these emissions. Keeping the air clean by minimizing the combustion of fossil fuels, less use of vehicles, use of catalytic converters can help in reducing the air pollution. Reusing waste allows the minimal production of non-degradable waste. Hence, the correct answer is 'Reusing wastes'.
