Deciduous plants which clean the atmosphere
The deciduous trees that tend to lose their leaves absorb a greater amount of chemical components of polluting of others plants and researchers have shown in particular more effective in cleaning the air by volatile organic compounds that are released into the atmosphere by human activities such as vehicles and building materials. To be able to metabolize this type of chemical components the deciduous plants produce larger quantities of enzymes that make these substances less toxic, in addition, the plants normally to protect against insects and various irritants tend to produce greater amounts of lymph for fight infections, but the mechanism in the case of polluting chemicals can also be harmful to the plants. To note also that climate change and frequent droughts change the absorption (in negative) of carbon dioxide.
