Endocrine disruptors (ED) are exogenous agents capable of deregulating the normal functioning of the endocrine system in humans and animals. The ED entry routes in the environment highlight the launch of domestic and agricultural wastewater in water bodies. This work aims to evaluate the occurrence, mobility and biosorption attenuation of hormones and antibiotics in soil columns in the application of agricultural and domestic waste and rain simulation. Soil columns, which were filled with soil from an agricultural area, were installed under the conditions of a swine wastewater application (ARS) at a dose of 50 m3/ha with and without the biosorbent effect and human urine at a rate equivalent to nitrogen compared with ARS. The estrogen concentrations were observed by High-performance liquid chromatography coupled with diode array detector (HPLC-DAD), and the mass balance was developed to evaluate the estrogen removal in the soil profile. The occurrence of hormones in all analyses was approximately 20%. Pine bark adsorbent was found to be considerably efficient in removing hormones from liquid matrices. The mass balance of the soil columns with adsorbent exhibited an estrogen recovery in the matrix applied to less than a 1% rate. For comparison, the soil columns without adsorbent obtained a mass transit about 20% of the total applied.

“…Herbicides are chemicals and usually synthetic compounds used to control weeds and increase the productivity of agricultural systems. However, they may be harmful to human and animal life, and may be transported from the soil to waters by surface draining and percolation (Kaufmann et al, 2012).In the state of Rio Grande do Sul, surface water often contain herbicides used in rice paddies (Primel et al, 2005;Sarcinelli, 2005;Bortoluzzi et al, 2006;Fernandes Neto and Sarcinelli, 2009).…”

Unplanned use and occupation of the land without respecting its capacity of assimilation and environmental purification leads to the degradation of the environment and of water used for human consumption. Agricultural areas, industrial plants and urban centres developed without planning and the control of effluent discharges are the main causes of water pollution in river basins that receive all the liquid effluents produced in those places. Over the last decades, environmental management has become part of governmental agendas in search of solutions for the preservation of water quality and the restoration of already degraded resources. This study evaluated the conditions of the main watercourse of the Sinos River basin by monitoring the main physical, chemical and microbiological parameters described in the CONAMA Resolution no. 357/2005.The set of parameters evaluated at five catchment points of water human consumption revealed a river that has different characteristics in each reach, as the upper reach was class 1, whereas the middle and lower reaches of the basin were class 4. Monitoring pointed to households as the main sources of pollutants in those reaches, although metals used in the industrial production of the region were found in the samples analyzed.Keywords: water quality, Sinos River, land usage. Monitoramento de metais, compostos orgânicos e coliforms em pontos de captação de água da bacia hidrográfica do Rio dos Sinos ResumoO uso e ocupação do solo não planejados, sem respeitar sua capacidade de assimilação e de purificação ambiental, levam à degradação do ambiente e da água utilizada para consumo humano. Áreas agrícolas, plantas industriais e centros urbanos desenvolvidos sem planejamento e controle de descargas de efluentes são as principais causas de poluição da água em bacias hidrográficas que recebem todos os efluentes líquidos produzidos naqueles lugares. Nas últimas décadas, gestão ambiental tornou-se parte das agendas governamentais em busca de soluções para a preservação da qualidade da água e a restauração de recursos já degradadas. Este estudo avaliou as condições do curso de água principal da bacia do Rio dos Sinos, monitorando o principal físico, químico e microbiológicos parâmetros descritos na Resolução CONAMA n.º 357/2005. O conjunto de parâmetros avaliados em cinco pontos de captação de água para consumo humano revelou um rio que tem características diferentes em cada alcance, como o superior chegar era classe 1, Considerando que o atinge médio e inferior da bacia foram classe 4. monitoramento apontado famílias como as principais fontes de poluentes naqueles atinge, apesar de metais utilizados na produção industrial da região foram encontrados nas amostras analisadas.Palavras-chave: qualidade da água, Rio dos Sinos, uso do solo.
