A batch experiment was conducted to examine the effects of six low-molecular-weight organic acids on the mobilization of arsenic and trace metals from a range of contaminated soils. The results showed that the organic acids behaved differently when reacting with soil-borne As and trace metals. Oxalic acid and acetic acid had the strongest and weakest capacity to mobilize the investigated elemen...

It is not uncommon for the Foundation Lecturer to gather material from personal archives and this has, to some extent, been the custom of previous lecturers of whom I name but two: our illustrious founder, Dr. Sydney Dyke, and one of my teachers, Dr. J. G. Greenfield. This I shall do relating my findings in some diseases due to trace metals to published work by other investigators. My interest ...

Despite WHO standards, waterborne diseases among the human being are rising alarmingly. It is known that the prolong exposure to contaminated water has major impact on public health. The effect of chemical contaminations in drinking water on human being is found to be chronic rather than acute and hence can be defined "consumption of contaminated drinking water could be a silent killer". As the...

The purpose of this study is to recognize the contamination characteristics of trace metals in soils and apportion their potential sources in Northern China to provide a scientific basis for basic of soil environment management and pollution control. The data set of metals for 12 elements in surface soil samples was collected. The enrichment factor and geoaccumulation index were used to identif...

It is evident that the metabolism of some trace metals is altered in diabetes mellitus and these micronutrients may have specific roles in the pathogenesis and progression of the disease. The aim of this study was to determine the status of trace elements; iron, copper, selenium and lead in obese diabetic patients. The study was carried out on two hundred and four (204) subjects, aged 20-68yrs ...

This study was carried out to find any relative concentrations of the trace metals (Cu, Cd, Zn and Pb) in the liver and the kidney of Acipenser persicus and in the surficial sediments of the west coast of The Southern Caspian Sea. Twenty five samples of the Acipenser persicus (Persian sturgeon) and ten samples of the sediments were taken from five fishing stations in autumn 2001. The tissues we...

Estimating standard-exceeding probabilities of toxic metals in soil is crucial for environmental evaluation. Because soil pH and land use types have strong effects on the bioavailability of trace metals in soil, they were taken into account by some environmental protection agencies in making composite soil environmental quality standards (SEQSs) that contain multiple metal thresholds under diff...
