BIOMAGENTIC MONITORING OF AIR POLLUTION USING DUST PARTICLES OF URBAN TREE LEAVES AT UPPER EGYP
Six common tree species were used to check their suitability to use as magnetic biomonitors for particulate air pollution. The morphology and chemical composition of their leaf dust were identified using SEM/EDX. The results showed that the shape of particles are sphers, ovoid, irregular or grouped into aggregates; they were well within the size range of urban dust, especially hazardous ... إقراء المزيد

Effect of milk processing on the distribution of some trace elements in its products
SUMMARY The effect of some milk processes on the distribution of Fe, Zn, Cd and Pb elements in the resultant products had been investigated. The levels of these elements in raw milk and the obtained products were estimated in ppm. The distribution in respect of these elements during the separation of buffalo's raw whole milk into cream and skim milk ... إقراء المزيد

Isolation and characterization of heavy-metal resistant microbes from roadside soil and phylloplane
Abstract Contamination by heavy metals is one of the major environmental problems in many countries and these contaminants reach from various sources such as traffic cars and other activities. Soil and phylloplane samples were collected from eight traffic and two non-traffic sites in Sohag city, Egypt. Heavy metal contents of Cd2+, Zn2+ and Pb2+ of soil and phylloplane samples were ... إقراء المزيد

Response of Antioxidant Enzymes in Pyrchantha Coccnia as Biomarkers for the Detection of Pb in Urban Atmosphere
The utility of antioxidant enzymes, via superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) and glutathione peroxidase (GPX), as biomarkers of lead pollution in urban atmosphere of Baku was investigated by using the Pyrchantha coccnia. At higher lead concentrations (105.74 ppm), CAT, SOD, APX and GPX exhibited remarkable induction (22.9968, 3.3664, 3.324 and 81.318 unit g-1 FW, respectively) with increasing ... إقراء المزيد
