“…Pinho et al (2004) show that presence of atrazine in the water of overland flow isn't constant, but contamination peaks coincide with the first rains after herbicide is applied to the soil. To summarize, atrazine contamination level in this case depends on chemical, physical, and biological properties of herbicide, type and location of soil on the landscape, tillage practices, frequency of use of the herbicide and occurrence of rain after application (GERECKE et al, 2002).…”

Atrazine is still being used in no-till corn production in Brazil. This herbicide can be moved by overland flow and leached in the soil profile. In both ways, it can pollute water, either by reaching the groundwater or lakes and streams close to the crop field. This study evaluated the presence of atrazine in a dystrophic Yellow-Red Argisol and a dystrophic Melanic Gleisol in a corn field, where atrazine has been applied for 11 years. Overland flow was the main process of atrazine transport on hillslope and leaching was the most important process in the floodplain. Frequency and location of atrazine application in the landscape define this herbicide contamination process.Index terms: Herbicide, overland flow, maize. RESUMOAtrazina ainda é empregada em áreas sob plantio direto para a produção de milho no Brasil. Esse herbicida pode ser transportado por escoamento superficial ou pela lixiviação no perfil do solo. De uma forma ou de outra, ele pode contaminar a água do subsolo ou de lagos e cursos d'agua próximos à área de plantio. Este estudo avaliou a presença de atrazina em um Argissolo Vermelho-Amarelo distrófico e em um Gleissolo Melânico distrófico em uma área de cultivo de milho, onde a atrazina tem sido utilizada há 11 anos. O escoamento superficial foi o principal processo de transporte de atrazina na encosta e a lixiviação foi o predominante na várzea. A frequência e a localização da aplicação de atrazina na paisagem definem o processo de contaminação deste herbicida.Termos para indexação: Herbicida, escoamento superficial, milho.

“…The racemization was biologically mediated and led to residues of MCPP and DCPP in these waters, which were enriched in the (S)-enantiomers. Gerecke et al also reported ER of MCPP [125]. MCPP is used in a racemic ratio (R/S-MCPP) in urban areas for protection and conservation of materials, whereas only (R)-MCPP is used in all other applications as agriculture.…”

Abstract:In recent decades, the presence of micropollutants in the environment has been extensively studied due to their high frequency of occurrence, persistence and possible adverse effects to exposed organisms. Concerning chiral micropollutants in the environment, enantiomers are frequently ignored and enantiomeric composition often neglected. However, enantioselective toxicity is well recognized, highlighting the need to include enantioselectivity in environmental risk assessment. Additionally, the information about enantiomeric fraction (EF) is crucial since it gives insights about: (i) environmental fate (i.e., occurrence, distribution, removal processes and (bio)degradation); (ii) illicit discharges; (iii) consumption pattern (e.g., illicit drugs, pharmaceuticals used as recreational drugs, illicit use of pesticides); and (iv) enantioselective toxicological effects. Thus, the purpose of this paper is to provide a comprehensive review about the enantioselective occurrence of chiral bioactive compounds in aquatic environmental matrices. These include pharmaceuticals, illicit drugs, pesticides, polychlorinated biphenyls (PCBs) and polycyclic musks (PCMs). Most frequently analytical methods used for separation of enantiomers were liquid chromatography and gas chromatography methodologies using both indirect (enantiomerically pure derivatizing reagents) and direct methods (chiral stationary phases). The occurrence of these chiral micropollutants in the environment is reviewed and future challenges are outlined.

“…Les perturbateurs endocriniens (PE) sont à l'origine de nombreuses perturbations de la faune aquatique et constituent un risque pour la santé humaine (ESPLUGAS et al, 2007;GERECKE et al, 2002;TIXIER et al, 2003). Ils échappent, pour la plupart, au traitement classique des eaux usées.…”

Les effluents issus des stations d’épuration des eaux usées industrielles et municipales contiennent des quantités non négligeables de polluants organiques, inorganiques et microbiens, qui sont rejetés dans l’environnement par voie directe, ou en suivant la filière de réutilisation (irrigation ou arrosage, etc.). Ces eaux résiduaires constituent l’une des principales sources de contamination des eaux de surface et souterraines (augmentation de la demande chimique en oxygène (DCO), coloration et eutrophisation des cours d’eau, etc.). Dans l’optique de palier le déficit croissant des ressources en eau destinées à la consommation humaine, ces eaux résiduaires sont de plus en plus soumises à des traitements poussés en vue d’une réutilisation. Cette réutilisation doit toujours être réalisée dans l’objectif de fournir une eau présentant, en continu, une qualité spécifique liée à l’usage attendu (eau de production, eau de lavage, eau de refroidissement, eau d’irrigation ou d’arrosage, etc.). Les procédés conventionnels peuvent s’avérer non adaptés, notamment par leur manque de fiabilité dans la qualité des eaux traitées et le risque encouru de contamination microbiologique. Pour faire face à cette importante problématique, les techniques membranaires, notamment les bioréacteurs à membrane (BRM), peuvent constituer une avenue potentielle de traitement et de réutilisation de ces effluents. L’intérêt de ces procédés réside dans leur aspect non polluant, leur facilité d’automatisation et leur capacité à éliminer simultanément les différents polluants en une seule étape de traitement. Ces technologies offrent la possibilité de clarifier et de désinfecter simultanément les eaux sans risque de formation de composés organo-halogénés. Dans cet article, les BRM sont situés par rapport aux techniques conventionnelles de traitement biologique d’effluents. Par la suite, un accent particulier est mis sur la présentation des connaissances actuelles concernant les principes de base des BRM, les critères d’application et les conditions d’opération qui influencent les performances de ces technologies. Les développements récents portant sur la modélisation mathématique de fonctionnement et de colmatage de ces modules sont également présentés. Finalement, les applications industrielles et les coûts d’implantation et d’opération de ces technologies sont brièvement discutés.Effluents from urban and industrial wastewater treatment plants contain organic (e.g., COD, BOD, total suspended solids, endocrine disrupting compounds), inorganic (e.g., phosphorus, ammonia nitrogen, nitrites and nitrates, metals) and microbial pollutants (e.g., bacteria, viruses, parasites), which are either directly discharged into the environment or reused for agricultural purposes. These wastewaters are often responsible for pollution of surface and groundwater (increasing the COD, colour and eutrophication of water, for example). In the context of finding solutions for water shortages, wastewaters are more and more frequently subjected to tertiary treatment for wate...
