But what can be done against this pollution? There are some very efficient plants that are crazy about these pollutants.
Plants “breathe” through a phenomenon called photosynthesis which allows them to naturally reduce CO2. But in addition to this known mechanism, certain plants and flowers purify the surrounding air. This is called “bio-purification” or “purification by the living”.
Plants that can do this purify the air by storing toxic chemicals in their cells or by transforming them. Scientists then use the term phytoremédiation, from the Greek phyto which means plant and remediation which means rehabilitation.
Which plants to choose?
