The meta-analysis of this study found three key findings: the negative effects of acid rain on plant growth-related traits were estimated, and aboveground and belowground parts may respond differently. The acidity of the soil is a significant factor in the negative effects of acid rain on plant growth. Acid rain removes minerals and nutrients from the soil, which are essential for plant growth. Nutrient-fewer leaves become unable to absorb these nutrients, affecting plants’ biochemical, physiological, and cellular processes. It also affects gene expression and increases the chance of alien invasion.
The mechanisms of how acid rain affects plants include leaf photosynthesis (e.g., destruction of leaf chloroplast), enzyme activities, and the overall health of plants. Acid rain generally slows plant growth by generating abnormalities in plant metabolism such as photosynthesis, chlorophyll content, nitrogen, and sulphur metabolism. Over time, the acidic water alters the pH of the soil where plants are growing, binding and dissolving vital minerals and carrying them.
Soil acidification caused by acid rain can damage plant roots, negatively impacting plant health. Acid rain affects plants by regulating plant-associated soil microorganisms and inducing soil acidification and nutrient deficiency. Acid rain application causes reduction in leaf area, which directly impacts root and shoot growth and overall plant growth.
Acid rain also has deleterious effects on the agricultural ecosystem by retarding crop growth and affecting their production. In many regions globally, anthropogenic driven acid gas emissions have caused acid rain, and efforts have been made to assess its effects. Protecting plants from acid rain is crucial for their survival and well-being.

How does acid rain affect plants pdf?
The detrimental effects of acid rain on plant growth are primarily attributed to its capacity to enhance abnormalities in plant metabolism. These abnormalities encompass processes such as sunlight, nitrogen, and sulfate digestion, although there are instances where this is not the case.
What is the effect of acid rain on soil?
The detrimental effects of acid rain on soils and freshwaters are widely acknowledged. The dissolution and subsequent release of toxic aluminum, the leaching of nutrients from soils, and the subsequent lowering of soil fertility are all causes for concern, as they have the potential to harm fish and plants.
How does acidity affect plant growth?
Acidity in soil can decrease the availability of plant nutrients like phosphorus and molybdenum, and increase the availability of toxic elements like aluminium and manganese. Essential plant nutrients can also be leached below the rooting zone. Acidity can degrade the environment for bacteria, earthworms, and other soil organisms, and can inhibit the survival of useful bacteria like rhizobia bacteria that fix nitrogen for legumes.
Soil pH is a measure of acidity or alkalinity, with a pH of 7 being neutral, above 7 being alkaline, and below 7 being acid. It can be measured in water or calcium chloride, with the pH varying depending on the method used.
What are 3 effects of acid rain?
Acid rain has severe environmental impacts, including damage to trees, freshwaters, soils, and aquatic life. It also causes paint peeling, corrosion of steel structures, and weathering of stone buildings and sculptures. It also affects human health. Alternative energy sources like solar and wind power, nuclear power, hydropower, and geothermal energy are being used to reduce acid rain emissions. Acid rain also affects plant health by changing the pH of the land, affecting overall growth, and binding or dissolving essential soil minerals like nitrogen and phosphorus.
What are the five effects of acid rain?
Acid rain is a harmful weather phenomenon that occurs when atmospheric pollutants like nitrogen and sulphur react with rainwater, resulting in highly acidic water droplets. This precipitation is caused by air emissions, particularly disproportionate levels of sulphur and nitrogen emitted by vehicles and manufacturing processes. It can cause damage to trees, freshwaters, soils, and aquatic life-forms, cause paint peeling, corrosion of steel structures, and weathering of stone buildings and sculptures.
Acid rain also impacts human health by causing damage to trees, freshwaters, soils, insects, aquatic life-forms, paint peeling, corrosion of steel structures, and weathering of stone buildings and sculptures.
How does acid rain affect the crops?
Acid rain significantly impacts urban vegetation, causing morphological defects in plants, including deformation of margins, color changes, and brown, spotted necrotic lesions. This slows plant growth by generating abnormalities in plant metabolism, such as photosynthesis, chlorophyll content, nitrogen metabolism, and production of reactive oxygen species. However, there are also exceptional cases of growth promotion.
Anatomically, acid rain can cause alterations in cuticle thickness, cellular deformation, occlusion of stomatal cells, loss of trichomes in the epidermis, cell collapse in the mesophyll, and the formation of scar tissue.
The impact of acid rain on urban ecosystems is complex and requires further understanding. As human populations mainly concentrate in large cities, it is crucial to prioritize measures to characterize the resilience of urban ecosystems and find a balance between human activities and the long-term conservation of natural habitats. Understanding the response of plants within urban environments and their response to pollution episodes is essential for determining suitable sensitive, indicator, or tolerant species for better design biomonitoring plans in cities.
This work aims to describe the damage caused by acid rain at lab-simulated pH values, determining leaf morphological and anatomical changes, as well as chlorophyll content, in two frequent tree species.

How does acid rain affect plants’ growth?
The study aims to investigate the impact of acid rain on soil and crops in India. It will use three different solutions of acidic water, created using pH buffers, to analyze their effects on soil nutrient levels and wheatgrass growth. The buffers will be mixed with spring water to create solutions with pH levels of 4, 5, 6, and 7, or neutral. Acidic rainwater with a pH below 5. 65 is considered acidic. The solutions will be used to water wheatgrass seeds throughout the experiment, and the results will be displayed in various data charts and graphs.
The Clean Air Act, passed in 1970 and amended in 1990, has reduced sulfur dioxide and nitrogen oxides in the atmosphere, making rainwater less acidic. The study aims to provide a more comprehensive understanding of the effects of acid rain on soil and crop growth.
What is the pH of acid rain?
The pH scale measures the acidity of an object, with basic objects being less acidic. Pure water has a pH value of 7, while normal rain has a slightly acidic pH between 5. 0 and 5. 5. Acid rain, produced by power plants and automobiles, has a pH value of 4. 0. A decrease in pH values from 5. 0 to 4. 0 indicates a 10 times greater acidity. High-tech devices, such as litmus paper, are used to measure pH in laboratories. When touched to a substance, the paper changes color to indicate acidity or basicity. Acidic substances turn red, while basic substances turn blue.
Is acid rain harmful to some plants and animals?
Acid rain can significantly impact various animals and plants, affecting the entire food web. For instance, it can lead to the death of phytoplankton in lakes, causing insects to rely on it for food. This results in their demise, which in turn affects other animals like fish, birds, frogs, and salamanders. As a result, the food web becomes less available for these animals, leading to a continuous cycle of food scarcity. Although acid rain may not directly affect specific plant or animal species, it can significantly impact the entire ecosystem.
Which plants are most affected by acid rain?
The impact of acid rain stress on plant species varies. Coniferous trees are more susceptible to this stressor than broad-leaved trees. The findings of studies conducted by the Three-Gorges Reservoir Area Research Station of Beijing Forestry University and the Yunfu State-Owned Forest Farm and Forest Park Management Station substantiate this conclusion.
