The effects of air pollution on plants
Over the past 5 years, research has been conducted on ozone damage to agricultural products, particularly in the three corn, soybean and cotton crops in the United States. The study estimated that the damage to this gas on agricultural crops is estimated at $ 1.5 billion annually by installing farms at the farm level and controlling the amount of ozone. Increased airborne contaminants lead to reduced flowering, fruiting and ultimately poisoning of trees.
Air pollution damage to plants, trees and crops is a phenomenon that has received less attention and less research in the country has examined the number and figure of economic and environmental damage.
Air pollution and sensitization of plants
Research by environmental experts suggests that ozone pollutants in the air can affect the sensitivity of trees and plants in addition to flowering and fruiting.
According to research, airborne contaminants cause the leaves of the plant to become defensive and close against air pollutants. The type and degree of reaction of the plant leaf depends on the amount of ozone, the degree, intensity and duration of exposure to ozone.
Certain ozone exposure is usually more effective at high humidity than low humidity, because at high humidity the holes are more open and gas exchange is easier. As a result of air pollution, the vegetation of the plant disappears and causes the leaves of the plant to provide the necessary nutrients for the trees and plants; thus, the nutrients of the plant do not reach the trees and plants and no signs of contamination by the plant. The air can be seen in the form of plant decay.
This results in exposure to low concentrations of ozone and long-term air pollution, leading to the plant becoming more susceptible to disease and making the plant vulnerable.
In this way, ozone pollutants can reduce photosynthesis, reduce leaf area, reduce water productivity and reduce flower and fruit in the plant.
Impact of air pollution on the growth of trees
Environmentalists’ research shows that air pollution can also cause trees to shrink. With a 2 percent annual growth decline for trees due to air pollution, a total of 2 percent of a tree’s height is less than when not exposed to air pollution. Decrease in tree growth is mainly due to nitrogen oxide and sulfur dioxide gases that lead to acid rain and disrupt plant and tree growth. More than 5% of the trees on the outskirts of Tehran are semi-arid due to the accumulation of harmful particles on their foliage. As the air pollution increases, the plant species adapted to Tehran’s climate have gradually changed from leaf to leaf conifers.
Change the appearance of plants
Changing compatible species from broadleaf to acorn leaves is another contributor to increased air pollution, as the air-purifying ability of acorns is less than broadleaf.
Studies show that the fog oxidant may cause a yellow stain on the acorn leaves and they fall off early. As a result, there will not be enough leaves to produce plant nutrients and the root system will be damaged, which in turn will damage the plant’s growth and make the plant more susceptible to insects, for example.
According to the above, special attention should be paid to reducing air pollution, and one of the available solutions is to use materials such as Adblow to lower the emissions of diesel engines, plants are undoubtedly the largest land purifiers and We must protect and protect them because of the precious gem.
Pakro is one of the leading companies in the Adblo industry.
