Geochemistry of surface hyporheic stream sediments, multivariate statistics and GIS database proved successful tools for assessing toxic element contamination in East Attica region. The objectives of this study were to assess the degree of contamination and to describe the surface hyporheic stream sediment geochemical variations in relation to geology, lithology and anthropogenic activities of ...

Background & Aims of the Study: Due to the rapid industrial development in Khuzestan province of Iran during recent years, this study was performed to analyze the variation of metals concentrations (Mg, Mn, Ni, and Sn) in soil samples of Ahvaz II Industrial estate during the spring season of 2013. Materials & Methods: In this experimental study, 27 topsoil samples were co...

Within 20 min after intraperitoneal injection of Salmonella enteritidis endotoxin in rats, blood platelet-activating factor (PAF) increased from 4.3 +/- 1.3 to 13.7 +/- 2.0 ng/ml (P less than 0.01) and lung PAF from 32.3 +/- 4.9 to 312.3 +/- 19.6 ng (P less than 0.01), but not lung lavage PAF. We tested the effect of PAF receptor antagonists, CV 3988 and SRI 63-441, on endotoxin-induced hemodyn...

The pharmacokinetics of trimethoprim-sulfamethoxazole were studied in 12 healthy adult subjects receiving trimethoprim at 20 mg/kg of body weight per day and sulfamethoxazole at 100 mg/kg/day, which is the conventional dose for treating Pneumocystis carinii pneumonia (PCP). Daily doses were evenly divided and orally administered every 6 h for 3 days. Trimethoprim, sulfamethoxazole, and N4-acety...

The aim of the research is to determine macro (Ca, Mg, P and K), micro (Fe, Mn, Cu, Zn Be) element heavy metal (Al, Cr, Ni, Se Cd) contents some Astragalus taxa collected from nature. Nine (Astragalus gummifer, A. compactus, lineatus var. longidens, aureus, onobrychis, declinatus, lineatus, oocephalus subsp. stachyophorus, inereus) natural areas Bingöl province were used as plant material resea...

Abstract The geochemical distribution of heavy metals in peat soil profile and estimation water table patterns peatland oil palm plantation were carried out the Klias Peninsular West Coast Sabah. geological setting mainly consists Crocker Formation Quaternary Alluvium which composed soil. from 10 sites collected for analysis. geophysical surveys performed to measure table, influenced concentrat...

An area near the city of Chihuahua has been traditionally irrigated with wastewater to grow forage crops. It has been hypothesized that metal levels could be found in these soils high enough to cause potential health problems to the population. The objective of this study was to determine heavy metal concentrations in different soils due to irrigation practices. Four soil types were evaluated; ...
