Little information is available about the toxicity of toluene, ethylbenzene and xylene acting on macrophytes, and their toxicity data are rarely used in regulation and criteria decisions. The results extended the knowledge on toxic effects of toluene, ethylbenzene and xylene on aquatic plants. The responses of Hydrilla verticillata to these pollutants were investigated. Chlorophyll levels, lipid peroxidation,...
Effects of toluene, ethylbenzene and xylene on the contents of chlorophylls (a and b) were investigated in Hydrilla verticillata and Vallisneria spiralis. Hydrilla verticillata exhibited increases at lowest concentrations, while the loss in chlorophyll contents at higher chemicals concentrations occurred. Linear regression analyses were performed. IC10 values were 7.30mg/L, 1.15mg/L and 2.36mg/L for...
