摘要

研究了蝉体内7种有机磷酯(OPEs)和9种多环芳烃(PAHs)的浓度水平及其栖息地对蝉污染的影响因素。在日本对成年蝉、若虫外骨骼、土壤和汁液进行了取样。蝉体中7种OPEs和9种PAHs的总浓度分别为107 ~ 8940 ng/g-dw和58.9 ~ 1580 ng/g-dw。在成年蝉的头部、胸部和腹部检测到部分OPEs和PAHs。头部的浓度高于其他部位。土壤和蝉体内OPEs与多环芳烃呈显著正相关。对于某些有机酸和多环芳烃,随着蝉体内有机酸和多环芳烃浓度的增加,树液中的有机酸和多环芳烃浓度趋于升高。这些趋势表明,蝉从被这些污染物污染的土壤和汁液中摄取OPEs和PAHs。OPEs和PAHs的浓度随大气沉积的增加而增加。这可能说明大气沉积物中的OPEs和PAHs污染了土壤,蝉从被污染的土壤和土壤中摄取污染物。

Influence of Habitat Pollution on Organophosphate Esters and Polycyclic Aromatic Hydrocarbons in Cicadas
The present study examines the concentration levels of seven organophosphate esters (OPEs) and nine polycyclic aromatic hydrocarbons (PAHs) in cicadas and the influence factors of their habitats on the contamination of cicadas. Adult cicadas, nymphal exoskeletons, soils, and saps were sampled in Japan. The total concentrations of seven OPEs and nine PAHs for the adult cicadas ranged from 107 to 8940 ng/g-dw and from 58.9 to 1580 ng/g-dw, respectively. Some OPEs and PAHs were detected in heads, thoraxes, and abdomens of the adult cicadas. The concentrations were higher in the heads than in the other parts. The relationship between OPEs and PAHs in soils and those in cicadas was considerably positive. For some OPEs and PAHs, the concentrations in the saps tend to be higher as those in the cicadas increase. These tendencies indicate that cicadas intake OPEs and PAHs from soils and saps contaminated with these pollutants. The concentrations of OPEs and PAHs tend to increase with those in the atmospheric depositions. This probably shows that OPEs and PAHs in atmospheric depositions pollute soils, and cicadas intake the pollutants from the contaminated soils and saps.
