The source of most
sulfur dioxide
is high-sulfur coal burned in power plants. Controlling this source of sulfur dioxide production can have a major impact on acid rain in Pennsylvania and other regions of the Northeast.
Which energy source occurs natural in bedrock and leads to the formation of radon?
Radon gas is formed naturally when
uranium-238 undergoes radioactive decay
, producing energy and several radioactive products such as radon-222 and thorium-232. (The thorium later decays to emit energy and radon-220.)
Which of the following would be the most likely effect of acid deposition on the northern forest?
which of the following would be the most likely effect of acid deposition on a northern forest?
acid rain deposition actually rids the soil of very
important nutrients trees need to survive, like magnesium and calcium.
What is the majority of atmospheric mercury produced by?
The main primary anthropogenic sources of atmospheric mercury are
coal burning, mining for various metals, and industrial activities that process ores or produce cement
. In most of these activities, mercury is released as a (by-product) pollutant.
Is primarily responsible for acid rain?
Power plants release the majority of
sulfur dioxide
and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.
Carbon monoxide
does not react with water to form an acid. So, it would not contribute to acid rain. The last one is carbon dioxide: Carbon dioxide reacts with water to form carbonic acid thus contributing to acid rain.
Is acid rain still a problem in 2020?
The quick version: Yes, acid rain is still around, and
yes it’s still a problem
. … Rain is naturally slightly acidic, since picks up carbon dioxide in the air, producing carbonic acid. But when it starts absorbing industrial pollutants like sulfur dioxide and nitrogen oxide, the acidity becomes troublesome.
Dr. Ulrich believes that acid deposition is
the. primary (but not only) cause of forest decline and death
. … The continuing input of acids causes the soils to become more acidic over time, with a lowering of the soil pH.
Why forests are more likely to be damaged by acid rain if they are near cities?
Exhausts from cars cause the formation of nitrogen oxides in the air
. From these gases, airborne sulfuric acid (H
2
SO
4
) and nitric acid (HNO
3
) can be formed and be dissolved in the water vapor in the air. … That is why forests and lakes in the countryside can be harmed by acid rain that originates in cities.
What part of the world is most affected by acid rain?
Affected areas
Places significantly impacted by acid rain around the globe include most of
eastern Europe from Poland northward into Scandinavia
, the eastern third of the United States, and southeastern Canada. Other affected areas include the southeastern coast of China and Taiwan.
Does bedrock cause radon?
Hypothesis: Houses
above sedimentary bedrock will have higher levels of radon than
houses above igneous bedrock. This hypothesis was derived from the fact that sedimentary rocks have higher porosity and permeability than igneous rocks, therefore sedimentary bedrock will allow more radon gas to seep into houses.
Do all rocks emit radon?
Radon formation
Just as
uranium is present in all rocks and soils
, so are radon and radium because they are daughter products formed by the radioactive decay of uranium.
Do rocks emit radiation?
The natural radiation of soil and rock depends
upon mineralogical composition
. Rocks composed of minerals with relatively high concentrations of uranium, thorium, and potassium have relatively high natural radioactivity. Soils typically reflect the radioelement concentrations of their parent rock.
What is the biggest source of mercury contamination?
Mercury occurs naturally in the earth’s crust, but human activities,
such as mining and fossil fuel combustion
, have led to widespread global mercury pollution. Mercury emitted into the air eventually settles into water or onto land where it can be washed into water.
What are two major sources of mercury pollution?
Two major sources of mercury pollution includes
coal burning power plants, as well as waste incinerators
. One means of controlling mercury pollution is finding alternative energy sources, such as utilizing renewable energy sources.
Which disease is caused due to mercury contamination?
Minamata disease, sometimes
referred to as Chisso-Minamata disease, is a neurological disease caused by severe mercury poisoning. Signs and symptoms include ataxia, numbness in the hands and feet, general muscle weakness, loss of peripheral vision, and damage to hearing and speech.
