a total number of 67 workers of teheran battery workshops were investigated for probable lead absorption due to the working with lead storage batteries. twenty workers with other occupations were selected as control group. blood and urine analysis were carried out for both groups. lead content of the urine in about 95.5% of the subjects was below 10 μg/100 ml. two subjects showed higher concent...
Geogenic and anthropogenic activities introduce certain metals into the environment which tend to deteriorate the quality of both surface and groundwater in the Bosomtwe Crater Lake and its surroundings. In this study spatio-temporal variations in concentrations and risk assessment of selected trace metals (As, Fe, Pb, Zn, Cr, Cd and Ni) were investigated during the wet and dry seasons for surf...
The aims of this study were to determine Cd and Pb contents in wild mushrooms from the eastern region of the “Green Lungs” of Poland (GLP), compare them to Cd and Pb contents in some popular species of cultivated mushrooms, and evaluate mushroom contribution to the daily intake of Cd and Pb. Trace elements were determined in 21 species of edible mushrooms: 18 species of wild mushrooms and 3 spe...
OBJECTIVE We determined which children should be tested for elevated blood lead levels (BLLs) in the face of financial and practical barriers to universal screening efforts and within 2009 Centers for Disease Control and Prevention recommendations allowing health departments to develop BLL screening strategies. METHODS We used the Michigan database of BLL tests from 1998 through 2005, which c...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
The investigation of the anthropogenic contamination by heavy metals of soils is very important for environmental planning and monitoring in urban areas. In the present study, surface soils (0 20 cm) samples from 167 sampling sites in Xuzhou (China) were collected in 2010 and analyzed for heavy metals including Zn, Pb, Fe, Mn, Cu, Cd, Sr, Ba Cr, Ni and Mo via inductively coupled plasma/mass spe...
a survey on lead intoxication in lead mine workers was carried out among khanehsorme, lead miners in najafaabad and also in ab-bagh lead miners in shahreza, both located in district of esfahan, iran. the studies were carried out on 62 miners out of 82 employees in khanehsorme, 25 miners out of 27 employees in ab-bagh lead miners and 47 rural inhabitants in the surroundings of mines were selecte...
lead poisoning associated to residuals of batteries recycling was diagnosed in a small herd of holstein cattle. in this outbreak, 10 animals showed clinical signs of lead poisoning, 5 dead and others saved after chelating therapy with cana2edta.mean blood lead level of clinically intoxicated cattle was 0.624 ± 0.388 ppm and the levels varied between 0.320 and 1.300 ppm. blood and milk lead leve...
The aVR is often neglected lead. It is an unipolar lead facing the right superior surface. As all the depolarisations are going away from lead aVR, all waves are negative in aVR (P, QRS, T) in normal sinus rhythm. In dextrocardia, (True and technical) the p is upright in aVR. The lead aVR is a very important lead in localisation of Coronary Artery Disease. In the presence of anterior ST elevati...
