Air pollution in cities is particularly high in autumn and winter, when emissions are highest and the ability of plants to clean the air significantly decreases
Research in Wuhan, China, has shown that shrubs and herbaceous plants effectively remove particulate matter and heavy metals from the air, making them a valuable component of strategies to improve air quality during the winter. In optimizing urban greenery for effective air purification in autumn and winter, consideration of biodiversity should be key, as different plant species differ in their efficiency in collecting different pollutants and in their filtering activity at different times of the year.
