In regions with high livestock densities, the usage of antibiotics and metals for veterinary purposes or as growth promoters poses a risk in manured soils. We investigated to which degree the concentrations and depth distributions of Cu, Zn, Cr and As could be used as a tracer to discover contaminations with sulfonamides, tetracyclines and fluoroquinolones. Besides, we estimated the potential vertical translocation of antibiotics and compared the results to measured data. In the peri-urban region of Beijing, China, soil was sampled from agricultural fields and a dry riverbed contaminated by organic waste disposal. The antibiotic concentrations reached 110 μg kg?1 sulfamethazine, 111 μg kg?1 chlortetracycline and 62 μg kg?1 enrofloxacin in the topsoil of agricultural fields. Intriguingly, total concentrations of Cu, Zn, Cr and As were smaller than 65, 130, 36 and 10 mg kg?1 in surface soil, respectively, therewith fulfilling Chinese quality standards. Correlations between sulfamethazine concentrations and Cu or Zn suggest that in regions with high manure applications, one might use the frequently existing monitoring data for metals to identify potential pollution hotspots for antibiotics in topsoils. In the subsoils, we found sulfamethazine down to ≥2 m depth on agricultural sites and down to ≥4 m depth in the riverbed. As no translocation of metals was observed, subsoil antibiotic contamination could not be predicted from metal data. Nevertheless, sulfonamide stocks in the subsoil could be estimated with an accuracy of 35–200 % from fertilisation data and potential leaching rates. While this may not be sufficient for precise prediction of antibiotic exposure, it may very well be useful for the pre-identification of risk hotspots for subsequent in-depth assessment studies. 相似文献

The farming community is today faced with requests by various interest groups to implement environmental management systems (EMS). The series of items shows principle theoretical questions of the method and the advantages of EMS (part I and II), presents the practical outcome (part III) and give a recommendation for potential users of EMS in agricultural systems (part IV). The study conducted outlines the method of the implementing an EMS according to the Environmental Management and Audit System (EMAS) and ISO 14001. Further advantages and disadvantages for the agricultural industry are addressed. Even though terms such as site can not easily be defined or problems with open material cycles and structural particularity of agricultural farms there appears to be a benefit to implement. The transparency and documentation of the material flow as well as the economical benefits of an optimized organization count towards the EMS. Further EMS can be a means to strengthen the argumentative position for example with the public, authorities, banks or insurance. This concurs with minimizing company liabilities and obtaining governmental privileges (deregulation). 相似文献
