Competitive sorption between 17α-ethinyl estradiol and bisphenol A/4-n-nonylphenol by soils

引用

Journal of Environmental Sciences 2013年第6期25卷 1154-1163页

作者： Jianzhong Li Lu Jiang Xi Xiang Shuang Xu Rou Wen Xiang Liu School of Environment Tsinghua University

The sorption of 17α-ethinyl estradiol （EE2）, bisphenol A （BPA）, and 4-n-nonylphenol （NP） in single systems and the sorption of EE2 with different initial aqueous concentrations of BPA or NP were examined using three soils. Results showed that all sorption isotherms were nonlinear and fit the Freundlich model. The degree of nonlinearity was in the order BPA （0.537-0.686）〉 EE2 （0.705-0.858）〉 NP （0.875-0.0.951） in single systems. The isotherm linearity index of EE2 sorption calculated by the Freundlich model for Loam, Silt Loam and Silt increased from 0.758, 0.705 and 0.858, to 0.889, 0.910 and 0.969, respectively, when BPA concentration increased from 0 to 1000 μg/L, but the effect of NP was comparably minimal. Additionally, EE2 significantly suppressed the sorption of BPA, but insignificantly suppressed that of NE These findings can be attributed to the difference of sorption affinity of EE2, NP and BPA on the hard carbon （e.g., black carbon） of soil organic matter that dominated the sorption in the low equilibrium aqueous concentration range of endocrine-disrupting chemicals （EDCs）. Competitive sorption among EDCs presents new challenges for predicting the transport and fate of EDCs under the influence of co-solutes.

The prostate is an accessory sex gland that develops under precise androgenic control. It is known that hormonal imbalance may disrupt its development predisposing this gland to develop diseases during aging. Although the hypothesis regarding earlier origins of prostate diseases was proposed many years ago, the mechanisms underlying this complex phenomenon are poorly understood. Therefore, the aim of this study was to evaluate the prostates of old male gerbils exposed to testosterone during intrauterine and postnatal life using morphological, biometrical, stereological, Kariometric, immunohistochemical, and immunofluorescence analyses. Our findings demonstrate that prenatal and pubertal exposure to testosterone increases the susceptibility to the development of prostate diseases during aging. The presence of a more proliferative gland associated with foci of adenomatous hyperplasia in animals exposed to testosterone during the prenatal and pubertal phase show that the utero life and the pubertal period are important phases for prostatic morphophysiology establishment, which is a determinant for the health of the gland during aging. Therefore, these findings reinforce the idea that prostate disease may result from hormonal disruptions in early events during prostate development, which imprint permanently on the gland predisposing it to develop lesions in later stages of life.

Distribution patterns of octylphenol and nonylphenol in the aquatic system at Mai Po Marshes Nature Reserve,a subtropical estuarine wetland in Hong Kong

引用

Journal of Environmental Sciences 2007年第6期19卷 657-662页

作者： LI Xiang-li LUAN Tian-gang LIANG Yan WONG Ming-hung LAN Chong-yu Croucher Institute for Environmental Sciences and Department of Biology Hong Kong Baptist UniversityHong Kong China State Key Laboratory of Biocontrol School of life Sciences Sun Yat-Sen （Zhongshan） University Guangzhou 510275 China

Spatial and temporal distribution of octylphenol （OP） and nonylphenol （NP） in Mai Po Marshes, a subtropical estuarine wetland in Hong Kong, were investigated. Surface water samples were collected every month from 11 sites during the period of September- December 2004. Concentrations of OP and NP ranged from 11.3 to 348 ng/L and from 29 to 2591 ng/L, respectively. The high levels of NP and OP were found in November and December than in September and October. The levels of OP and NP have no significant spatial differences except September. Total organic matter in the sediments appeared to be an important factor in controlling the fate of these compounds in the aquatic environment.
