Effects on Animals and Plants: The impact of air pollution on animals is more or less similar to that on man. Ozone (O3) and peroxyacetylnitrate (PAN) produced in these complex reactions can become injurious to plants and other life forms, depending on concentration and duration of exposure. There is more pollution during acceleration and deceleration than during constant speed. Other times, it can harm or kill plants by changing growing conditions, such as by raising or lowering the environment’s acidity. Decomposition of organic matter under anaerobic conditions produces methane which on being oxidised in the atmosphere produces carbon monoxide. The burning of hydrocarbons in motor vehicle engines gives rise to CO2, CO, SO2 (sulfur dioxide), NOx (NO [nitrogen monoxide]) and NO2 in varying proportions—and C2H4 (ethylene), as well as a variety of other hydrocarbons. In urban areas these polluting gases may be present in such high concentrations that they cannot be detoxified rapidly enough to avoid injury. Unpolluted rain is slightly acidic, with a pH close to 5.6, because the CO2 dissolved in it produces the weak acid, H2CO3. All kinds of plants; ranging from our food crops to millions of … Plants and animals are harmed by air pollution. Humans are also regularly harmed by pollution. The effects of air pollution on plants develop over time and can’t be undone. There are many sources of air pollution such as car exhausts, smoke from a factory, or release of gases from paint or plastic production. Tall chimney stacks may be used to carry gases and particles to a high altitude and thus avoid local pollution, but the pollutants return to Earth, sometimes hundreds of kilometers from the original source. The toxic substances released from the soil also poisons the plants. The ozone layer in the atmosphere protects both plant and … The resulting acidic rain is harmful to trees, fish, animals and other organisms. Burning of coal produces a lot of smoke and dust whereas burning of petrol mainly produces sulphur dioxide. Plants pull carbon dioxide from the air into leaves and stems as part of photosynthesis. Decomposition of these matter also produces foul smelling gases. Long-term exposure to air pollution, for example, can lead to chronic respiratory disease, lung cancer and other diseases. For example, when plants are exposed to air containing NOx, lesions on leaves appear at an NOx concentration of 5 mL L–1, but photosynthesis starts to be inhibited at a concentration of only 0.1 mL L–1. Dilute acidic solution can remove mineral nutrients from leaves, depending on the age of the leaf and the integrity of the cuticle and surface waxes. Volcanic eruptions release oxides of nitrogen that pollute the atmosphere. When we pollute our air, we are also polluting the precipitation that falls into water bodies and soils. Pollution is the introduction of harmful contaminants into air, water or soil. Scientists believe that acidic water dissolves the nutrients and helpful minerals in the soil and then washes them away before the trees and other plants can use them to grow. When harmful particulates enter the air, pollution ensues. Automobiles: Petrol on combustion produces carbon monoxide, hydrocarbons, nitrogen oxides, aldehydes, sulphur compounds, organic acids and ammonia and carbon particles. Air pollutants have a negative impact on plant growth, primarily through interfering with resource accumulation. When sulfur dioxide and nitrogen oxides combine with water in the atmosphere, they form acid rain, which intoxicates the soil and waters where it falls, causing damage to plants. In soils that lack free calcium carbonate, and therefore are not strongly buffered, such additions of acid can be harmful to plants. Sometimes it is the pollutants themselves that cause damage. The three key plant parameters that govern these interactions – recognition, nutritional qualities and defence systems – will be affected with varying degrees of consequences. Ultraviolet radiation harms the wildlife and damages plants. Effect of air pollution on vegetation is a serious issue these days. Environmental extremes may either accelerate the production of reactive oxygen species or impair the normal defense mechanisms that protect cells from reactive oxygen species. When acid rain falls to Earth, it damages plants by changing soil composition; degrades water quality in rivers, lakes and streams; damages crops; and can cause buildings and monuments to decay.
