Study on Changes of Chlorophyll Content in plant under Indoor Benzene Stress

Benzene, as one of the "three stealth killers" of indoor air pollution, seriously threatens people's life and health. The change of chlorophyll content is one of the important bases for selecting the resistance of indoor plants to benzene pollution. The experiment was carried out using simulated cabin airtight method, changes of chlorophyll content in 8 common indoor plants under different concentrations of benzene pollution, which revealed the resistance of indoor plants to benzene pollution. The results showed that: Among the 8 indoor plants, Sansevieria trifasciata was the most resistant to benzene pollution, followed by Kalanchoe blossfeldiana, and Chlorophytum capense var. Variegatum was the weakest.
