Abstract
Air pollution in cities is increasingly
intensifying, exerting inevitable impacts on all living organisms, including
trees. Urban trees are vital for cities because the improve air quality and
regulate the climate: in metropolitan areas, the predominant inorganic
atmospheric pollutants include Nitrogen oxide (NOx), Sulphur oxide (SOx),
Carbon oxides (COx), Ozone (O3), and suspended Particulate matter
(PM2.5 and PM10). Each of these contaminants poses
significant risks to public health, while simultaneously including a range of
physiological and structural alterations in urban tree species and plants also
can indicate the level of pollution in the respective areas. Vegetation
captures gases, particulates and aerosols from the atmospheric more effectively
than other land surfaces. Particulate matter deposition in different plants not
only depends upon the sources and amount of pollutants in the environment but
also depends on morphological characteristics of plants like leaf size and
surfaces, texture, hair, wax, length of petiole, weather condition and wind
direction. Hence plants can be used as bio monitors and bio indicators of air
pollution. Dust interception capacities of plants can be exploit to use them as
sinks for atmospheric particulate pollutants. Literature available on these
aspects are reviewed and the highlights are depicted in this review paper.
