concentrations of cu, pb, cr, cd, mn, ni, fe and zn were determined in the muscle samplesof sarotherodon melanotheron from the fosu lagoon in cape coast using atomic absorption spectrophotometer. the results showed that, metal concentration in the fish muscle was in the order mn > zn > fe > pb > ni > cd > cu > cr. mean concentrations of pb and cd in the fish exceeded the maximum tolerable limit...

Objective: To investigate the serum concentrations of copper (Cu), zinc (Zn) and copper/zinc ratio (Cu/Zn) in patients with ovarian cancer and benign ovarian lesions. Methodology: The study included 50 patients, with ovarian cancer (malignant group) and 50 patients with benign ovarian lesions (benign group). After overnight fasting, blood samples were collected. The concentrations of Cu and Zn ...

Concentrations of Ni, V, Pb and Cu were determined in bottom sediments and liver, gills and fillet of Euryglossa orientalis and Chirocentrus nudus along the Bahrekan Bay in the Northwest part of the Persian Gulf in Iran. Sediment samples and fish species were collected during winter 2013 and spring 2014. Heavy metal analysis was performed by atomic absorption spectrophotometer. Results showed t...

An attempt was made to unravel further the mechanism by which high dietary concentrations of ascorbic acid influence copper metabolism. The addition of ascorbic acid to the diet of rats caused about a twofold increase in plasma ascorbate concentrations and reduced group mean plasma and tissue concentrations of Cu. The effect of 10 g ascorbic acid/kg diet was greater than that of 1 g/kg. Ascorbi...

Massive amounts of pig manure are produced by intensive pig farm in China, and the composition of pig manure has changed much due to the use of feed additives. However, little is known about the exact Cu (copper) feed as additives or present as contaminants in pig feed and the residues in feces. One hundred and thirty-seven feeds and one hundred and forty-two fecal samples from 48 pig farms wer...

The present study was carried out to investigate contamination of heavy metals in 19 fish species from the Banan section of Chongqing in the Three gorges, yangtze River. The results showed that the mean concentrations of heavy metals were higher in intestine than muscle, except zinc in upper strata. In the fish inhabiting the upper strata, there were significant differences between mean concent...

street dusts are suspended particle matters in the air from different natural and anthropogenic sources that may fall out because of their size and density. forty nine street dust samples were collected from some main streets of eastern and southern parts of tehran. one other sample was also collected from iran university of science and technology central campus for comparisons during summer un...

Concentrations of lead, copper, cadmium, and mercury were determined in sediments and two selected marine organisms (Cynoglossus arel and Panulirus homarus) collected from Jask Port, Darak Port, Pozm Port, Gulf of Chabahar and Gowatr Port in the north coasts of the Oman Sea during pre (spring) and post (autumn) monsoon in 2017. Heavy metals concentrations were determined by atomic absorption sp...
