BACKGROUND AND OBJECTIVES: Urban farming makes a substantial influence on the household economy of the urban poor especially in developing countries. Urban soil the hot spot of urban farming is a natural sink for contaminants especially the trace elements derived mainly from anthropogenic activities. This study’s aim was to quantify the concentrations of selected trace elements...

Public libraries are popular gathering places, so understanding the factors that contribute to colony-forming unit (CFU) concentrations and how minimize them is essential. This study aimed investigate affect CFU in a public library, using air sampling (Bioluminescent ATP-assay) statistical analysis software (SPSS) collect analyze data. The findings indicated concentration library was significan...

concentrations of elements (as, co, cu, ni, mo, pb, v, cd, cr and zn) are studied in the surface sediments of bakhtegan lake, northwest of nyriz city, iran, to assess metal contamination. the average abundance order of trace elements content in bakhtegan lake sediments is cr>ni> v> zn> cu> co> as> pb> mo>cd. the comparison of trace elements concentration in bakhtegan lake sediments with toxicol...
