ResumoDevido à localização estratégica em relação às rodovias federais e estaduais e aos incentivos fiscais, o município de Feira de Santana, na Bahia, sempre atraiu indústrias, tornando-se importante polo industrial. Instalado na região de nascente até a foz da bacia do rio Subaé, ele conta com um ramo diversificado de indústrias (alimentícias, agroindustriais, celulose, ração, metalúrgicas, entre outras), além do adensamento populacional no entorno dessas instalações, e de pequenas e médias propriedades rurais. A presente pesquisa quantificou os metais pesados totais: Cd, Cr, Cu, Ni, Mn, Pb e Zn nas águas superficiais ao longo do curso do rio Subaé em período de estiagem e analisou a correlação das concentrações encontradas de cada metal pesado com os parâmetros físico-químicos da água. Foram realizadas 3 amostragens em 13 Pontos de monitoramento, definidos em função do uso e ocupação do solo. Os resultados indicam o comprometimento da qualidade da água do rio Subaé -particularmente no alto curso, área urbana de Feira de Santanaprincipalmente pelas altas concentrações de Cu, Mn, Pb e Zn, oriundas provavelmente de atividades industriais, as quais se apresentam acima dos limites estabelecidos pelas resoluções do Conselho Nacional de Meio Ambiente 357/05 (Classe 2), que trata das águas superficiais. Palavras-chave: qualidade de água, rio Subaé, metais pesados. (food, agribusiness, pulp, food, metallurgical and others), beyond the population density around these facilities and small and medium farms. This research quantified the total heavy metals: Cd, Cr, Cu, Ni, Mn, Pb and Zn in Abstract Due to its strategic location in relation to federal and state highways, and tax incentives, the city of Feira de Santana, in Bahia, attracted industries making it important industrial center. This pole is installed in the region of the source to the mouth of the river basin and Subaé has a diversified industrial sector

“…Also, since most growth promoters contain metals, their use in animal production may elevate concentrations of these elements in manure (Nahm 2002). Raven and Loeppert (1997) suggested that the potential environmental hazard of toxic levels of trace elements in organic amendments depended on the elemental composition of the material, the fraction of the constituent element that is released, the mobility and toxicity of the released elements in the environment and the ease of incorporation of toxic elements into the biota. Further, they felt that the total elemental composition of a material (as measured in our study) can give a preliminary view of its potential for environmental contamination, and when composition and application rates are taken into account, an estimate of the maximum possible pollution caused through the use of a material can be determined.…”

Interest in composting as a means of handling the large volumes of manure generated by southern Alberta beef cattle feedlots has increased in recent years. We measured concentrations of 19 elements (C, N, P, Na, Ca, Mg, K, S, Al, Fe, Mn, Zn, Cu, Cr, Ni, P b , Co, Mo and Cd) in fresh manure, interim-composted manure and finished compost, at four commercial feedlots. Thirteen elements showed increased concentrations (by 26–73%) with composting, while four (C, Cr, Ni and Mo) showed concentration declines. Of the remaining two, the trend in N concentration was feedlot dependent, while Pb was largely unaffected. Total mass loss during composting averaged 54%, which represents a substantial decrease in haulage requirements. Overall average C losses were 61% and N losses 33%. On an equivalent wet weight basis ("as-is"), composting allowed haulage of 56% more N, 84% more P, 91% more Zn, and 76% more Cu than fresh manure, which is advantageous in terms of moving nutrients and trace elements from high to low-loading areas. Our study quantifies nutrient and trace element behaviour during composting, provides comparative data with fresh manure, and helps tailor end-use decisions (e.g., haulage distance, application rate) on the compost product. Key words: Manure, compost, beef cattle feedlots, nutrients, trace elements

Environmental toxicity due to cadmium (Cd) pollution in croplands causes critical problems worldwide. Rice (Oryza sativa L.) is an important crop in Asia, including South Korea, and numerous studies have evaluated the relationship between Cd and antioxidants to alleviate Cd uptake from the soil into plants. However, information about the relationship between phosphorus (P) and antioxidants in rice seedlings is still limited with regard to Cd phytotoxicity. We therefore investigated the physiological responses of rice (Oryza sativa L. cv 'Dongjin') seedlings to Cd toxicity and the effect of P application on reactive oxygen species (ROS) and antioxidant changes. The exposure of rice seedlings to 30 µM Cd inhibited plant growth; increased the contents of superoxide, hydrogen peroxide, and malondialdehyde; and induced Cd uptake by the roots and leaves. Application of P to Cd-exposed seedlings decreased Cd-induced oxidative stress by enhancing the capacity of ascorbate (AsA) production and ROS-scavenging, and decreased Cd transfer from the roots to the leaves. These results suggest that P application alleviated Cd-induced growth inhibition and oxidative damage by restricting Cd translocation from the roots to the leaves and maintaining sufficient levels of AsA.Keywords: Antioxidant, Cadmium, Phosphorus, Reactive oxygen species (ROS), Rice ) in roots (A, C) and leaves (B, D) of rice plants grown in the 30 µM Cd-treated hydroponics with or without 6 mM phosphorus (P) application at the four-leaf stage after 14 days.Ⓒ The Korean Society of Soil Science and Fertilizer.
