In this study, content changes nutrients four organic wastes, namely household waste, sewage sludge, chicken manure, cow/sheep were analyzed during composting, quality products was assessed view their impact on environment. objective study dete...

objective high concentration of iron and other trace elements could restrict bacterial growth and modify their metabolic pattern as well. however, this study aimed to find out the influence of iron, chromium, cadmium and synergism or antagonism between these elements on the growth of a gram positive bacterium. materials and methods in a series of experiments, bucillus cereus was cultured in a n...

the study of regional variations and the anthropogenic contamination by trace toxic elements of soils is very important for environmental planning and monitoring in urban areas. soil, sediment and rocks of urban areas of kerman studied to assess the degree of pollution by trace elements as a consequence of anthropogenic sources. 37 samples were collected and analyzed by icp-ms for 29 elements. ...
