Acid rain can be extremely harmful to forests. Acid rain that seeps into the ground can dissolve nutrients, such as magnesium and calcium, that trees need to be healthy. Acid rain also causes aluminum to be released into the soil, which makes it difficult for trees to take up water.
Acid rain and fog also damage forests, especially those at higher elevations. The acid deposits rob the soil of essential nutrients such as calcium and cause aluminum to be released in the soil, which makes it hard for trees to take up water. Trees’ leaves and needles are also harmed by acids.
The acid rain caused massive devastation to trees, soils, rivers and lakes. By 1984 almost half of the trees in the nearby Black Forest showed signs of damage and images of blackened skeletal trees helped fuel the environmental movement.
Acid rain leaches aluminum from the soil. … Acid rain also removes minerals and nutrients from the soil that trees need to grow. At high elevations, acidic fog and clouds might strip nutrients from trees’ foliage, leaving them with brown or dead leaves and needles.
Acid rain caused by industrial and vehicle emissions damages the leaves of trees, and causes them to produce smaller and fewer seeds. It also reduces the trees’ resistance to disease, pests, and frost. Clear cutting of forests is also a threat to this biome.
— In Poland, 7 percent of forest land is known to be affected, although environmentalists estimate the real level might be as high as 40 percent. Areas of Czechoslovakia have been reduced to acidified wastelands, and acid-rain damage is reported in Yugoslavia, Romania and Hungary.
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. … In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.
Conifers are most effected because the needles are bathed in acid droplets all year around. Other trees drop their leaves.
and (4) may cause harmful effects on soil, forests, streams, and lakes. Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids.
Because carbonic acid is a relatively weak acid, the ability of carbon dioxide alone to generate true “acid rain” is very limited. Acid rain is caused by industrial emissions of sulfur dioxide and nitrogen oxides (which form much stronger acids when equilibrated in rainwater).
Acid rain is responsible for severe environmental destruction across the world and occurs most commonly in the North Eastern United States, Eastern Europe and increasingly in parts of China and India.
Acid rain has ruined nearly half of the Black Forest in southwestern Germany. It has damaged the soil and the trees growing in it. … Acid rain pollutes rivers, like the Danube and the Rhine, and kills the wildlife living there. Germany has been working on the problem of acid rain.
Solution(By Examveda Team)
Poland has maximum damage to the forest been caused by acid rain.
If water is too acidic, calcium, magnesium and potassium levels are reduced. Calcium is required for cell growth, magnesium for chlorophyll formation and potassium for synthesizing proteins. If water is too alkaline, calcium builds up, effectively cutting off the flow of nutrients to plants’ roots.
Effects of acid rain: (1) Acid rain causes direct damage to leaves of plants. (2) Acid rain causes damage to fresh water life which decreases the fish population in lakes. (4) Acid rain removes basic nutrients such as calcium from the soil.
Acid rain pollution is a serious environmental problem in the world. … In general, the catalase, acid phosphatase, and urease activities increased with the SAR pH levels. However, the maximum amylase activity was found at pH 4.0 and decreased as the SAR pH increased from 4.0 to 5.0 or decreased from 4.0 to 2.5.
Acid rain at pH 4.0 or less decreased leaf water content, destroyed chloroplast structure, inhibited the expression of six chloroplast ATP synthase subunits, decreased chloroplast ATP synthase activity, and reduced photosynthesis and plant growth.
The results of this experiment showed that flowers given acid rainwater will die quicker. Both plants receive the same amount of water but different pH levels. By the fourth day the experimental group lost five flowers while the control group gained three flowers.
Explanation: If acid rain falls on the ground, it will damage soil and organisms that live in the soil. If it falls on plants, it may kill them. If it falls into lakes, it will lower the pH of the water, killing all aquatic organisms.
Acid rain indirectly affects other animals, such as mammals, which depend on animals like fish for food sources. The EPA reports that acid rain causes a reduction of population numbers and sometimes eliminates species entirely, which in turn decreases biodiversity.
A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power. Renewable energy sources help reduce acid rain because they produce much less pollution.
i. Acid rain may lead to the corrosion of buildings, monuments, bridges etc. ii. It increases acidity in the soil leading to its reduced fertility and affects the lives of aquatic animals.
The aquatic life is affected badly due to acid rain. … Further, the acid rain contains nitric acid which has nitrogen. The incorporation of nitrogen in water results in nitrogen pollution. This may result in a decrease in population of fishes and other small aquatic animals.
Acid rain decreases the pH of the soil, causing its acidity to increase, which decreases the level of important nutrients found in the soil. … The buffers will be mixed with spring water to create solutions with pH of 4, 5, 6, and 7, or neutral.
