The current study focused on quantifying hazardous heavy metals (As, Cd, Cr, Pb, Ni, and Zn) in soil-rice systems near the Buriganga River Bangladesh to assess their impact human health environment. mean concentrations of As, Zn soil exceeded FAO/WHO acceptable limits, metal pollution index (MPI) indicated that all samples collected from rice fields were severely polluted (MPI?30) than water gr...

Pot experiments were carried out during the two successive summer seasons of 2010 and 2011 in the greenhouse of Crops Physiology Research Department, Field Crops Research Institute, Agricultural Research Center, Giza, Egypt to investigate the effect of pollution with cadmium at concentrations of 50, 100 and 200 ppm on vegetative growth, leaf anatomy, yield and certain physiological aspects of s...

Surface sediments contamination to heavy metals was evaluated in eight creeks of Mahshahr coastal waters (north-west of the Persian Gulf) from October. 2005 to November 2006. Sediments were collected seasonally by Peterson grab and the concentrations of heavy metals were measured using voltammetry and polarography methods. The range and the mean concentrations obtained in mg/kg were 15.03-35.16...

Background & Aims of the Study: Industrial wastewater sludges must be disposed in a safe way because they have hazardous effects on the human and environment. The aim of this study is to investigate the physicochemical characteristics and disposal options of sludges from oil-water separator (OWS) and dissolved air flotation (DAF) clarifier of a Refinery wastewater treatment plant. Material...

The status of metal concentrations including Pb, Cd, Cu, Ni, Zn and Fe in six species of Padina were determined in polluted (Nayband Bay) and unpolluted (Bostaneh port) areas on the Coast of the Persian Gulf. The mean concentrations of metals in the sediment of two locations were: Pb (12.64), Cd (3.59), Cu (21.74), Ni (17.00), Zn (32.00) and Fe (677.53) µg g-1 dry weight, respectively. In ...

Spirometric data from 86 primary school children living in an area of air pollution resulting from wire reclamation incineration were analysed and compared with 92 non-exposed schoolchildren. There were lower values for forced vital capacity and forced expiratory volume and thus a higher incidence of pulmonary function abnormalities in the children in the polluted area than those in a non-pollu...

this work studies the biosurfactants production which enables the diesel biodegradation byusing mixed microbial consortia from polluted sites. it was carried out by culturing three microbial consortia(named as xa, xb and xc) obtained from polluted soils, and enriched in diesel as sole carbon source.batchexperiments were done to study the effects of three variables (temperature,hydrocarbon conce...

This work presents the first results from winter field campaigns focusing on trace metals and metalloid chemistry in the snow cover from an urbanized region in central Poland. Samples were collected between January and March 2013 and trace element concentrations were determined using GF-AAS. A large inter-seasonal variability depending on anthropogenic emission, depositional processes, and mete...
