If urban pollution is to be reduced, plant mixed species of trees

Sweden: A study found that different people should clear a space of a tree of native species. This is because each tree values ​​different types of emotions.

According to experts from the University of Katenburg in Switzerland, cypress (conifer) trees are better at absorbing polluted air than broad-leaved trees. This means that each type is capable of absorbing various denominations.

Scientists say that the tree's pointed thorns and leaves not only clean the air better but also reduce the number of toxic materials in the air. However, experts were also interested in determining which tree might be the best. In this regard, eleven distinct plant species have been studied by researchers in Gothenburg.

The same conditions and environment were maintained for each tree. The trees were sprayed with 32 different kinds of pollutants, including various gases and particles of varying sizes. Polycyclic aromatic hydrocarbons (PAHs) are also included.

It was discovered that cypress trees absorb more pollutants, including PAHs. In the winter, when there is a lot of fog and pollution, these trees also filter the air. After that, it was discovered that the tree's pointed ridges, thorns, and stalks also absorb more of the atmosphere. However, broad-leaved trees are also pollutant capturers due to their large surface area and similar characteristics.

According to the same study, chlorophyll in plants does not decrease as a result of any kind of pollution. This is the motivation behind why various sorts of trees can clean the quality of the city in a superior manner.

However, experts have stated that randomly planting trees in narrow streets may be detrimental rather than beneficial. Although there will be a reduction in pollution absorption as a result of this, dirty air may remain trapped there for an extended period due to the interruption of air circulation.
