How does urban vegetation impact air pollution levels ?
Urban vegetation, including trees, shrubs, and grasses in urban areas, plays a crucial role in mitigating air pollution. It improves air quality by reducing pollutants such as carbon dioxide (CO2), nitrogen oxides (NOx), and particulate matter (PM). Plants absorb CO2 from the atmosphere during photosynthesis, which helps to reduce the concentration of this primary greenhouse gas contributing to global warming. Trees also store carbon in their biomass, effectively removing it from the atmosphere through a process known as carbon sequestration. The large leaf surface area of urban vegetation helps to capture and reduce nitrogen oxides (NOx) in the air. When NOx comes into contact with plant leaves, it reacts with the stomata to form nitrates, which are then absorbed by the plant. Soil microorganisms play a vital role in breaking down organic matter and converting it into nutrients that plants can use. These microorganisms also help to reduce NOx levels by converting them into harmless compounds such as nitrogen gas. Urban vegetation can trap particulate matter (PM) through its leaves and bark, preventing it from being inhaled by humans and animals. This helps to reduce the health risks associated with PM exposure, such as respiratory problems and cardiovascular diseases. Trees act as wind breaks, reducing wind speed and preventing PM from becoming airborne, which helps to keep PM levels low in urban areas and improve overall air quality. In conclusion, promoting urban green spaces and encouraging the planting of more trees and shrubs in cities is essential to mitigate the negative effects of air pollution.
