Biomonitoring Atmospheric Pollution of Polycyclic Aromatic Hydrocarbons Using Mosses

Polycyclic aromatic hydrocarbons (PAHs), as the main components of petroleum (PHCs), are carcinogenic organic pollutants that occur widely in atmospheric environment with increasing concentration. Moreover, PAHs widespread all over world due to their high volatility and long-range transport potential. The monitoring is often limited by working conditions, especially around oil field operation areas other industrial areas. Mosses (Bryophyta), most sensitive atmosphere pollution indicators, can be easily collected have been used monitor including PAHs. Thus, characteristics influencing factors mosses’ absorption accumulation were discussed, application mosses biomonitoring summarized. Biomonitoring include Dicranum scoparium, Hypnum cupressiforme, Thamnobryum alopecurum, Thuidium tamariscinum, Hylocomium splendens, Pleurozium scheberi, etc. Currently, methods for chemical analysis method, index purity (IAP) ecological survey Moss-bag technique. using has a relatively wide range prospects.
