background: cigarette butts have been shown to release numerous kinds of chemicals such as heavy metals in water and may be a continual source of aquatic environments contamination after discarding. the objective of the present study was to determine the concentration of cd and pb in cigarette filters of different iranian and non-iranian brands in smoked and non-smoked samples. methods: ten dif...
A Review on the Cadmium Content of Rice, Daily Cadmium Intake, and Accumulation in the Kidneys: Tomoyuki KAWADA, et al. Department of Public Health, Gunma University School of Medicine—The body burden of cadmium primarily depends on the daily intake of the element in food, and thus the geographical differences in cadmium content in foods and the daily intake of cadmium should be studied. There ...
the pollution of soil by heavy metals is considered to be quite a big problem in many areas ofthe world. to limit the accumulation of lead and cadmium from soil in the products, a correct understanding ofthe characteristics and specifications of the translocation of cadmium and lead is necessary. in order to evaluatethe effects of cadmium and lead interaction on zinc and manganese concentration...
Soil pollution and crop contamination by cadmium (Cd) and Arsenic (As) are widely-known and recognized as a global threat to sustainable life and the environment. Various factors contribute to soil pollution, including pollutants factor: sources of pollutants, pollutant pathways, the medium of pollution, and soil factor. Japanese agricultural soils in some region, have been heavily polluted wit...
every year the entrance of factory wastes such as shiraz petrochemical complex, marvdasht sugar cube factory, and charmineh factory, and other industrial units into the kor and sivand rivers and also the entrance of the marvdasht and zarghan city sewer system wastes into the kor river and the use of their water in the cultivation of the rice has caused a significant increase in the lead and cad...
Environmental pollution with the nephrotoxic metal cadmium is considered a potential health risk for the general population. In 1976 it was reported that the cadmium concentration in human kidney cortex in Sweden had increased in parallel with increasing levels in soil and grain during the twentieth century. Since the cadmium concentration in farming lands is still increasing, the present study...
Cadmium is a major environmental toxicant that is released into the atmosphere, water and soil in the form of cadmium oxide, cadmium chloride, or cadmium sulfide via industrial activities, such as the manufacturing of batteries and pigments, metal smelting and refining and municipal waste incineration. In the present study, we investigated the effects of cadmium exposure on sperm quality parame...
The common marine mussel A4yt~lus edulls was used in laboratory-controlled experiments to investigate the effects of exposure to cadmium on immune capability Haemolymph was extracted from mussels exposed for 7 d to 40 and 400 pg 1 ' of cadmium, and assays were carned out to investlgate the potent~al for immune response The assays included total and differential haemocyte counts, the release of ...
Introduction: Arsenic, beryllium, cadmium and nickel have been associated with the prevalence of diabetes mellitus in populations exposed to these elements. However, diabetes mortality has not been evaluated. This ecological study correlated airborne concentrations of these metals with diabetes mortality in North Carolina counties. Methods: County level data were extracted from the 2000 US Cens...
The present paper studies the content of heavy metals: Fe, Mn, Zn, Cu, Pb, Ni and Cd in the foliage of an indicator plant dandelion as collected from the lawns and parks of the Warsaw metroplitan area. The results suggest heavy accumulation of Fe, Zn, Pb and Cd as a consequence of the impact of traffic-born pollution. Keywords! dandelion, indicator plant, zinc, copper, iron, lead, cadmium, poll...
