“…The concentrations of endocrine disrupting chemicals (EDCs) were determined in accordance with the method reported by Zhao et al (2009) using gas chromatography-mass spectrometry under negative chemical ionization mode (GC-NCI-MS: Agilent 6890 N gas chromatograph connected to an Agilent 5975B mass spectrometer with a chemical ionization source). Polycyclic aromatic hydrocarbons (PAHs) in the effluents were determined using the method recommended by Barco-Bonilla et al (2009). Identification and quantification of the dioxins (PCDD/Fs), polychlorinated benzophenyls (PCBs) and polybrominated diphenylethers (PBDEs) were carried out using a GC/MS (Agilent 6890 N-5975B, Agilent Ltd., USA) according to the methods reported by Moon et al (2008).…”

“…Eles podem ser monoaromáticos: possuem um anel aromático, também conhecidos como BTEX (benzeno, tolueno, etilbenzeno e xilenos -isômeros: orto-, meta-e para-xileno); e poliaromáticos (HPA): possuem dois ou mais anéis aromáticos. Os HPA são altamente hidrofóbicos e são menos solúveis à medida que possuem mais anéis aromáticos, sendo geralmente encontrados adsorvidos a partículas do solo (BONILLA et al, 2009). A Agência de Proteção Ambiental dos Estados Unidos (USEPA) considera 16 HPA como Poluentes Orgânicos Persistentes (POP), podendo ser carcinogênicos e mutagênicos devido a sua capacidade de reagir com o DNA.…”

O ecossistema manguezal é um dos mais produtivos do planeta e possui relevante importância ecológica. Ele oferece diversos serviços como a proteção da região costeira, imobilização de contaminantes, e é fonte de alimento e refúgio para diversos organismos. No entanto, os manguezais encontram-se frequentemente ameaçados por atividades antrópicas. Os derrames de petróleo em áreas próximas a manguezais, por exemplo, são fontes potenciais para entrada de contaminantes como metais pesados e hidrocarbonetos. Dentre outras fontes, podem-se citar os resíduos industriais e de esgotos, a mineração e o uso de fertilizantes. Esses contaminantes alcançam os manguezais, podendo causar diversos efeitos negativos e afetar seu equilíbrio.

Wastewaters from various industries are a main source of the contaminants in aquatic environments. The authors evaluated the hormonal activities (estrogenic/anti‐estrogenic activities, androgenic/anti‐androgenic activities) and genotoxicity of various effluents from textile and dyeing plants, electronic and electroplate factories, pulp and paper mills, fine chemical factories, and municipal wastewater treatment plants in the Pearl River Delta region by using in vitro bioassays (yeast estrogen screen [YES]; yeast androgen screen [YAS]; and genotoxicity assay [umu/SOS]) combined with chemical analysis. The results demonstrated the presence of estrogenic, anti‐estrogenic, and anti‐androgenic activity in most industrial effluents, whereas no androgenic activities were detected in all of the effluents. The measured estrogenic activities expressed as estradiol equivalent concentrations (EEQs) ranged from below detection (3 of 26 samples) to 40.7 ng/L, with a mean of 7.33 ng/L in all effluents. A good linear relationship was found between the EEQs measured by YES bioassay and the EEQs calculated from chemical concentrations. These detected estrogenic compounds, such as 4‐nonylphenol and estrone, were responsible for the estrogenic activities in the effluents. The genotoxic effects expressed as benzo[a]pyrene equivalent concentrations (BaP EQs) varied between below detection and 88.2 µg/L, with a mean of 8.76 µg/L in all effluents. The target polycyclic aromatic hydrocarbons were minor contributors to the genotoxicity in the effluents, and some nontarget compounds in the effluents were responsible for the measured genotoxicity. In terms of estrogenic activities and genotoxicity, discharge of these effluents could pose high risks to aquatic organisms in the receiving environments. Environ. Toxicol.
