| Abstract | A set of human pharmaceuticals enables identification of groundwater that is influenced by sewage and provides information on the time of recharge. As the consumption rates of the investigated pharmaceuticals have changed over time, so too has the composition of the sewage. At the study area, south of Berlin (Germany), irrigation was performed as a method of wastewater clean-up at sewage irrigation farms until the early 1990s. Today, treated wastewater is discharged into the surface-water-stream Nuthegraben. Groundwater and surface-water samples were analyzed for the pharmaceutical substances clofibric acid, bezafibrate, diclofenac, carbamazepine and primidone, the main ions and organic carbon. The pharmaceutical substances were detected at concentrations up to microgram-per-liter level in groundwater and surface-water samples from the Nuthegraben Lowland area and from the former irrigation farms. Concentrations detected in groundwater are generally much lower than in surface water and there is significant variation in the distribution of pharmaceutical concentrations in groundwater. Groundwater influenced by the irrigation of sewage water shows higher primidone and clofibric-acid concentrations. Groundwater influenced by recent discharge of treated sewage water into the surface water shows high carbamazepine concentrations while concentrations of primidone and clofibric acid are low.La présence de substances médicamenteuses dans une eau de nappe influencée par vidange permet son identification et fournit une information sur son temps de recharge. Les taux de consommation humaine des substances relevées changeant avec le temps, il en est de même de la composition de l’eau de vidange. Dans la zone d’étude au Sud de Berlin (Allemagne), l’épandage a été pratiqué pour épurer l’eau jusqu’au début des années 1990. Aujourd’hui, l’eau est déversée après épuration dans le cours d’eau Nuthegraben. Des échantillons d’eau de nappe et d’eau de surface ont été analysés pour l’acide clofibrique, bezafibrate, diclofénac, carbamazépine, primidone, les ions principaux et le carbone organique. Les substances ont été détectées à des taux atteignant le microgramme par litre dans les échantillons d’eau de nappe et d’eau de surface de la zone des basses terres du Nuthegraben et des zones d’épandage. Les concentrations dans l’eau de nappe sont généralement beaucoup plus basses que dans l’eau de surface et il y a une variation significative de la distribution des concentrations dans l’eau de nappe. L’eau de nappe influencée par épandage montre des concentrations plus élevées en primidone et acide clorofibrique. L’eau de nappe influencée par le déversement récent d’eau épurée dans l’eau de surface, montre des concentrations de carbamazepine élevées, tandis que les concentrations en primidone et acide chlorofibrique sont basses.Un conjunto de productos farmacéuticos humanos permite la identificación de agua subterránea que está influenciada por aguas residuales y provee información sobre el tiempo de recarga. Como las tasas de consumo de los productos farmacéuticos investigados han cambiado con el transcurso del tiempo, de la misma manera lo ha hecho la composición de las aguas residuales. En el área de estudio, sur de Berlín (Alemania), se llevó a cabo un método de limpieza de las granjas de irrigación con aguas residuales hasta el principio de la década del 90. En la actualidad, el agua residual tratada se descarga en la corriente de agua superficial Nuthegraben. Se analizaron muestras de agua superficial y agua subterránea para investigar las sustancias farmacéuticas ácido clofíbrico, bezafibrato, diclofenaco, carbamazepina y primidona, los iones principales y el carbono orgánico. Las sustancias farmacéuticas fueron detectadas en concentraciones hasta el nivel de microgramos por litro en las muestras de aguas superficial y subterránea provenientes de las tierras bajas del área de Nuthegraben y de las antiguas granjas de irrigación. Las concentraciones detectadas en agua subterránea son generalmente mucho menores que en el agua superficial y hay en el agua subterránea una variación significativa en la distribución de las concentraciones de los productos farmacéuticos. El agua subterránea influenciada por la irrigación de las aguas residuales muestra concentraciones más altas de primidona y ácido clofíbrico. El agua subterránea influenciada por recientes descargas de aguas residuales tratadas en el agua superficial muestra altas concentraciones de carbamazepina mientras que las concentraciones de primidona y ácido clofíbrico son bajas.一些人用药物能够证明地下水受生活污水的影响并提供关于补给时间的信息。所调查药品的消耗量随时间变化,生活污水的组成也发生相应变化。在研究区,即德国柏林的南部,在二十世纪九十年代早期之前,用生活污水灌溉是处理污水的方法。如今,生活污水在处理过后排入Nuthegraben河。本文分析了地下水和地表水样药用物质降固醇酸、苯扎贝特、双氯高灭酸、氨甲酰氮草和普里米酮,以及主要离子和有机碳。从Nuthegraben Lowland 地区和以前的灌溉农场的地下水和地表水样中,药用物质测试的浓度高达每公升微克的水平。地下水中检测的浓度比地表水低很多,而且地下水中的药物浓度分布有显著差异。受生活污水灌溉影响的地下水显示高浓度的普里米酮和降固醇酸。受最近经过处理的生活污水补给 地下水显示高氨甲酰氮草浓度,而普里米酮和降固醇酸浓度偏低。Um conjunto de fármacos humanos permite identificar água subterrânea que é influenciada por água residual doméstica e fornece informação acerca do tempo de recarga. Uma vez que as taxas de consumo dos fármacos investigados têm sofrido alterações ao longo do tempo, a composição da água residual doméstica também tem sido modificada. Na área de estudo, a sul de Berlim (Alemanha), a rega foi desenvolvida como um método de depuração de água residual doméstica em terrenos selecionados para este tipo de rega até ao início dos anos 90. Atualmente, a água residual doméstica tratada é descarregada na água superficial do rio Nuthegraben. Foram analisadas amostras de água subterrânea e água superficial para as substâncias farmacêuticas ácido clofíbrico, bezafibrato, diclofenaco, carbamazepina e primidona, iões principais e carbono orgânico. As substâncias farmacêuticas foram detetadas com concentrações até ao nível do micrograma por litro nas amostras de água subterrânea e água superficial da área do Baixo Nuthegraben e dos antigos terrenos de rega. As concentrações detetadas na água subterrânea são geralmente muito mais baixas do que na água superficial e existe uma variação significativa na distribuição das concentrações dos fármacos na água subterrânea. A água subterrânea influenciada pela rega com água residual doméstica revela concentrações mais elevadas de primidona e ácido clofíbrico. A água subterrânea influenciada pela descarga recente de água residual doméstica na água superficial revela concentrações elevadas de carbamazepina, enquanto as concentrações de primidona e ácido clofríbrico são baixas. |
