中国地表饮用水水源地有机类内分泌干扰物污染现况分析 总被引:2,自引:0,他引:2
有机类内分泌干扰物(EDCs)是一类对人类和生物内分泌系统产生干扰,并可造成其紊乱的特殊外来物质,对人类和生物健康有极大的危害.以与人类生活密切相关的地表饮用水水源地中的有机类EDCs为研究重点,对中国目前地表饮用水水源地EDCs污染状况、污染物种类及其来源及可能的污染途径进行了评述.目前,中国各地区地表饮用水水源地均有有机类EDCs检出.其中以有机氯农药六六六及其异构体、DDT及其代谢产物和多氯联苯检出率最高,且某些地区检测浓度相当高,主要来源是农药使用和污水排放.国内外对地表饮用水水源地EDCs突发污染事件的研究均较少,应引起高度重视. 相似文献

采用固相萃取-气相色谱法研究了邯郸某污水处理系统污水和污泥中内分泌干扰物的存在水平,在污水和污泥中均检测出多氯联苯类、多环芳烃类、邻苯二甲酸酯类、酚类和有机氯农药五大类内分泌干扰物,除多氯联苯浓度在μg水平外,其他4种内分泌干扰物的浓度均在ng水平。污水处理系统进水以及污泥中它们的平均浓度分别在19.43 ng/L~60.82μg/L和43.94 ng/g~167.45μg/g之间,污水经过处理后,平均去除率在16.6%~77.9%之间。在污水处理过程中,多氯联苯、多环芳烃和有机氯农药主要通过污泥吸附去除,而邻苯二甲酸酯和酚类则主要通过生物降解作用去除。 相似文献

邻苯二甲酸酯(PAEs)作为环境中广泛存在的一类内分泌干扰物,其污染问题已经引起广泛关注。针对土壤中PAEs的检测方法、分布特征、环境来源和风险评价等方面进行综述。土壤样品前处理及分析测试过程中环境、试剂等存在痕量的目标化合物会影响最终检测结果的准确性,排除此环节中的污染干扰尤为重要,色谱—质谱联用技术是精准分析此类化合物的发展方向。中国土壤中PAEs普遍检出,PAEs含量与人类活动和生产方式密切相关,其控制标准和风险评价大多采用国外标准,一定程度上影响了中国不同类型及功能区划土壤质量评价的科学性和客观性。环境友好分析测试技术的开发应用、风险评价体系的建立健全及环境溯源技术的发展将是今后土壤中PAEs研究的主要方向。 相似文献

The aim of this study was to test a specific method for the detection of Vitellogenin (Vtg) and Zona Radiata Proteins (Zrp) in plasma from peregrine falcon (Falco peregrinus) as specific biomarkers for the evaluation of the effects of endocrine disruptors. The method was assayed with different peregrine falcon individuals (including mature and immature birds of both sexes) from a Spanish population being studied in terms of their contamination with organochlorine compounds with endocrine disrupting properties. This study shows that mouse anti bird Vtg monoclonal antibody ND3C3 (Biosense) seems to be the most specific antibody in binding plasmatic lipoproteins in peregrine falcon when compared to other anti Vtg antibodies. Rabbit anti salmon Zrp polyclonal antibodies O146 (Biosense) show cross-reactivity with Zrp in the samples studied. These preliminary results confirm the applicability of both of these diagnostic tools assayed (induction of Vtg and Zrp) in detecting exposure to Endocrine Disrupting Chemicals (EDCs) in this species. The increase of Vtg and Zrp detected in male specimens suggest a potential hazard to EDCs in the peregrine falcon which represents a species still affected by organochlorine compounds, and in particular those with estrogenic activity. 相似文献

Experimentally nonylphenol-polluted diet induces the expression of silent genes VTG and ERα in the liver of male lizard Podarcis sicula 总被引:1,自引:0,他引:1

Endocrine Disruptor Chemicals (EDCs) with estrogen-like properties i.e nonylphenol (NP) induce vitellogenin (VTG) synthesis in males of aquatic and semi-aquatic specie. In the oviparous species VTG is a female-specific oestrogen dependent protein. Males are unable to synthesize VTG except after E2 treatment.This study aimed to verify if NP, administered via food and water, is able to induce the expression of VTG even in males of vertebrates with a terrestrial habitat such as the lizard Podarcis. By means of ICC, ISH, W/B and ELISA we demonstrated that NP induces the presence of VTG in the plasma and its expression in the liver. VTG, undetectable in untreated males, reaches the value of 4.34 μg/μl in the experimental ones. Expression analysis and ISH in the liver showed that an NP-polluted diet also elicits the expression of ERα in the liver which is known to be related to VTG synthesis in Podarcis. 相似文献

Endocrine disrupting chemicals (EDCs) can alter endocrine function in exposed animals. Such critical effects, combined with the ubiquity of EDCs in sewage effluent and potentially in tapwater, have led to concerns that they could be major physiological disruptors for wildlife and more controversially for humans. Although sewage effluent is known to be a rich source of EDCs, there is as yet no evidence for EDC uptake by invertebrates that live within the sewage treatment system. Here, we describe the use of an extraction method and GC-MS for the first time to determine levels of EDCs (e.g., dibutylphthalate, dioctylphthalate, bisphenol-A and 17beta-estradiol) in tissue samples from earthworms (Eisenia fetida) living in sewage percolating filter beds and garden soil. To the best of our knowledge, this is the first such use of these techniques to determine EDCs in tissue samples in any organism. We found significantly higher concentrations of these chemicals in the animals from sewage percolating filter beds. Our data suggest that earthworms can be used as bioindicators for EDCs in these substrates and that the animals accumulate these compounds to levels well above those reported for waste water. The potential transfer into the terrestrial food chain and effects on wildlife are discussed. 相似文献

Broad range analysis of endocrine disruptors and pharmaceuticals using gas chromatography and liquid chromatography tandem mass spectrometry 总被引:3,自引:0,他引:3
Endocrine disrupting compounds (EDCs) and pharmaceuticals and personal care products (PPCPs) have been globally detected in impacted natural waters. The detection of trace quantities of EDCs and PPCPs in the environment is of great concern since some of these compounds have known physiological responses at low concentrations. EDCs can have a wide range of polarities, acidic and basic moieties, and exist in trace quantities, which often requires numerous complex extractions, large sample collection volumes, and multiple instrumental analyses. A comprehensive method has been developed allowing for the analysis of 58 potential EDCs in various water matrices using a single solid-phase extraction (SPE) of a 1 L sample with subsequent analyses using both gas chromatography and liquid chromatography, each coupled with tandem mass spectrometry (GC–MS/MS and LC–MS/MS). Instrument detection limits ranged between 0.12–7.5 pg with corresponding method reporting limits of 1–10 ng l−1 in water. Recoveries for most compounds were between 50% and 112% with good reproducibility (RSD 6–22%). 相似文献

An inter-laboratory comparison exercise was organized among European laboratories, under the aegis of EU COST Action 636: “Xenobiotics in Urban Water Cycle”. The objective was to evaluate the performance of testing laboratories determining “Endocrine Disrupting Compounds” (EDC) in various aqueous matrices. As the main task three steroid estrogens: 17α-ethinylestradiol, 17β-estradiol and estrone were determined in four spiked aqueous matrices: tap water, river water and wastewater treatment plant influent and effluent using GC-MS and LC-MS/MS. Results were compared and discussed according to the analytical techniques applied, the accuracy and reproducibility of the analytical methods and the nature of the sample matrices. Overall, the results obtained in this inter-laboratory exercise reveal a high level of competence among the participating laboratories for the detection of steroid estrogens in water samples indicating that GC-MS as well as LC-MS/MS can equally be employed for the analysis of natural and synthetic hormones. 相似文献
