Municipal solid waste（MSW） is an important destination for abandoned plastics. During the waste disposal process, large plastic debris is broken down into microplastics（MPs） and released into the ***, current research only focuses on landfill leachates, and the occurrence of MPs in other leachates has not been studied. Therefore, herein, the abundance and characteristics of MPs in three types of leachates, namely, landfill leachate, residual waste leachate, and household food waste leachate, were studied, all leachates were collected from the largest waste disposal center in China. The results showed that the average MP abundances in the different types of leachates ranged from（129 ± 54） to（1288 ± 184） MP particles per liter(particles.L-1) and the household food waste leachate exhibited the highest MP abundance（p 80%） of small MPs（20–100 μm） in landfill leachates compared to other leachates. To the best of our knowledge, this is the first study discussing the sources of MPs in different leachates, which is important for MP pollution control during MSW disposal.

Assessing the estrogenic potency in a Portuguese wastewater treatment plant using an integrated approach

引用

Journal of Environmental Sciences 2010年第10期22卷 1613-1622页

作者： Mário S.Diniz Rita Maurício Mira Petrovic Maria J.López De Alda Leonor Amaral Isabel Peres damiá barceló Fernando Santana Universidade Nova de Lisboa Faculdade de Ciencias e TecnologiaREQUIMTEDep.de Quimica Universidade Nova de Lisboa Faculdade de Ciencias e TecnologiaDep.de Ciencias e Engenharia do Ambiente Department of Environmental Chemistry-IIQAB-CSIC c/Jordi Girona

The estrogenic potency of a wastewater treatment plant （WWTP） was evaluated using chemical and biological analyses, which showed that after the station treatment processes some of the selected endocrine disruptor compounds （EDCs） were still present in the treated effluent （e.g., bisphenol A, alkylphenols, estrone）. Thus, the most common endocrine EDCs were identified and quantified and the overall estrogenicity of the treated effluent assessed by integrating the results. Male goldfish （Carassius auratus） were used as biological indicators in a 28-day experiment. Vitellogenin （Vtg）, gonadosomatic and hepatosomatic indices, steroids （17β-estradiol and 11-ketotestosterone） and histopathology were biomarkers used in fish to evaluate WWTP treated effluent estrogenicity, in combination with instrumental analyses. The results showed a significant increase （P 〈 0.01） in plasma and liver Vtg, which were significantly correlated （r = 0.66; P 〈 0.01）. The gonadosmatic index was significantly （P 〈 0.01） reduced in exposed fish. The steroid analyses revealed significant elevations in 17β-estradiol and depressed 11-ketotestosterone concentrations. The histological examinations show changes in exposed fish gonads, such as regressed testes and in some cases （43% to 75%） the development of ovo-testis in fish exposed to 50% and 100% treated effluent.
