Everyone knows that plants help nature and the environment, the forests they are the lung of the world but not everyone imagines that simple bushes and ivy can be the salvation for the inhabitants and the cities. A new report published by the magazine ACS Environmental Science and Technology has highlighted how trees and bushes can help reduce the levels of the majors atmospheric pollutants. Doesn't it seem like anything new? It has been shown that the efficiency of plants is eight times higher than previously thought.
With high levels of air pollution, even just walking through the windows of the city becomes harmful. Exposure toair pollution it has dire consequences on human health. If neighborhoods were designed to facilitate pedestrian activities, the world would be a better place.
The study published on the ACS was funded by the Department of Engineering and Physical Sciences of the English Research Council. The study focuses on an urban environment program sustainable. To obtain a clean and pedestrian-proof environment, the concentrations of nitrogen dioxide (NO2) and fine dust.
In Italy the limit of fine particles is exceeded in many cities (here the data), therefore that of the pedestrian is not an easy life at all! The addition of plants, trees and green elements such as hedges and bushes could greatly improve the quality of theair in urban areas. The study claims that the effects of plants halve the concentrations of carbon dioxide and microscopic particles of particulate matter.
In particular, nitrogen dioxide would be reduced by 40% and particulate matter by 60%. TO reduce atmospheric pollution it is not so much the trees as the grass, so the idea of giving new life to billboards and the walls of some buildings: climbing ivy is excellent for this purpose.
