Effects of air pollution on plants

Human industrial production and commercial activities lead to air pollution, which will bring short-term and long-term damage to plants As many countries have targeted restrictions and controls, the air pollution level in most developing countries is reducing, but it is still an important issue worthy of attention Ammonia, nitrogen dioxide, sulfur dioxide and ozone are some of the air pollutants that have the greatest impact on plants Direct chemical damage from sulfur and nitrogen emissions from heavy industry can damage plants, including large forests Sulfur dioxide and nitrogen dioxide damage plants by destroying cell membranes, inhibiting respiration and photosynthesis This leads to stunting, leaf shedding and damage, and is more susceptible to insect damage Plants damaged by sulfur dioxide look pale, like they have been bleached Ozone pollution is also the air pollution that will bring negative effects to plants The accumulation of tropospheric ozone will have a significant impact on plants This kind of gas blocks the stomata of plants, hinders the respiration and reduces the photosynthesis rate of plants, and therefore weakens or even kills plants Ozone entering plants through stomata also destroys plant cells In turn, the thinning of the ozone layer in the atmosphere caused by chemical pollution can also damage plants by exposing them to too much ultraviolet light Particle damage is caused by small particle air pollution from coal or cement dust, which will form a film on the leaves of plants, reduce the brightness of leaves and reduce the photosynthesis rate of plants Toxic dusts such as cement contain chemicals that dissolve plant leaf tissue Particulate pollution that falls on the ground can also cause damage to plants, because the roots of plants absorb toxic substances from the soil Acid rain is formed by the combination of acid chemicals in air pollution and water in the atmosphere These acids can seriously damage plants Acid rain destroys plant leaves and penetrates into the soil, making it difficult for plant seeds to germinate and grow In addition, acid rain can also affect agriculture and lead to reduced food production.
