AbstractCommon carp (Cyprinus carpio) is one of the most important cultured fish species in Poland. The aims of our study were to determine the concentration of essential minerals in the muscle tissue of carp obtained from a pond culture and to compare the content of these minerals with the physiological norms of nutrition for the Polish population, Recommended Dietary Allowances (RDA), and Estimated Average Requirements (EAR). The non-carcinogenic and carcinogenic risk by assessment of the Estimated target hazard quotients (THQ), total target hazard quotients (ΣTHQ), and carcinogenic risk were also studied. The muscle tissue of the carp was rich in macroelements. The pattern significance gradation of element concentrations was as follows: Na > K > Ca > P > Mg > Al > Zn > Fe > Cu > Mn > Cr > Se > Co. The concentration of toxic heavy metals in the samples was lower than the maximum allowable level of metals in food products. The risk of consumption of toxicants by an adult at a daily intake of 100 g of fish was 1.45% for Pb, 0.1% for Hg, 0.02% for Cd, and 0.02% for As, compared to the allowable daily intake for each toxicant. The value of the target hazard quotients of each metal was less than 1, indicating that the intake of a single metal through the consumption of carp meat does not pose a considerable health hazard. The total value of the target hazard quotients was also less than 1, indicating the safety of the combined effects of the chemicals. The major risk contributor was Pb with 82.9%, followed by Hg (9.38%), As (6.43%), and Cd (1.29%).

Zone Of Influence

There are described an algorithm and methods for collecting the evidential base for causing hazard to the health of the population of Zakamensk (the Republic of Buryatia) in the zone of influence of the waste of the past activities of the Dzhidinsky tungsten-molybdenum combine. The source of danger is lying sands, containing a complex of toxic heavy metals - lead, cadmium, manganese, nickel, chromium, etc. The algorithm for the formation of the evidential base included: a general analysis of the sanitary and hygienic situation; assessment in the dynamics of the quality of atmospheric air, drinking water, soil, food; assessment of the risk to the health of the population; epidemiological studies; in-depth clinical surveys of a representative group of city residents (280 people). In the blood of the examinees, heavy metals were identified as biological markers of the exposure. There was evaluated a complex of the response (effect) adequate to effects of laboratory markers. By methods of mathematical statistics there was established the presence of reliable relationships in the system “source of hazard - the quality of the environment - exposure to risk factors - health status.” The hazard to the health of a citizen, due to the negative impact of the factor, was considered to be proven if it was possible to build a continuous step-by-step logical chain of relationships between the source of the harmful effect, the quality of the habitat and the establishment of the fact of the disease. The quality of the habitat of the population of Zakamensk was shown to give rise in unacceptable risks to the health of residents. The main influencing factor is the pollution of atmospheric air, local food products and drinking water from public and private wells. Risks are realized in terms of a level of the primary morbidity rate of the population of the respiratory diseases, endocrine system, digestive organs that is relatively high compared to the matched area. The relationship between health hazard and environmental factors has been fully proved in 14% of the surveyed persons. At the same time, the territory was shown not be characterized as a zone of “ecological disaster” or “an emergency environmental situation”.

AbstractHeavy metals are present in low concentrations in reservoirs, but seasonal anthropogenic activities usually elevate the concentrations to a level that could become a health hazard. The dry season concentrations of cadmium, copper, iron, lead, mercury, nickel and zinc were assessed from three sites for 12 weeks in Oyun reservoir, Offa, Nigeria. Triplicate surface water samples were collected and analysed using atomic absorption spectrophotometry. The trend in the level of concentrations in the three sites is site C > B > A, while the trend in the levels of the concentrations in the reservoir is Ni > Fe > Zn > Pb > Cd > Cu > Hg. Ni, Cd, Pb and Hg were found to be higher than the WHO guidelines for the metals in drinking water. The high concentration of these metals was from anthropogenic watershed run-off of industrial effluents, domestic sewages and agricultural materials into the reservoir coming from several human activities such as washing, bathing, fish smoking, especially in site C. The health effects of high concentration of these metals in the reservoir were highlighted. Methods for the treatment and removal of the heavy metals from the reservoir during water purification such as active carbon adsorption, coagulation-flocculation, oxidation-filtration, softening treatment and reverse osmosis process were highlighted. Other methods that could be used include phytoremediation, rhizofiltration, bisorption and bioremediation. Watershed best management practices (BMP) remains the best solution to reduce the intrusion of the heavy metals from the watershed into the reservoir.

The presence of high level of heavy metals involves a human healthy risk that could induce chronic diseases. This work reports on the metal contamination due to heaps of steel-slag accumulated during more than 40 years in allotments and industrial areas in the southern part of Madrid (Spain). Several slag and soil samples were collected in an area of 10 km² and characterized by different conventional (XRD and XRF) and no so common methods (ESEM, thermoluminescence and EDS-WDS). The analysis reveal the presence of: (i) important amounts of Fe (43%), Mg (26%), Cr (1.1%), Mn (4.6%), S (6.5%) in the form of Fe-rich slag phases (wustite, magnetite...), Si and Ca-rich phases (larnite, ghelenite...), Cr (chromite), Mn (bustamite) and graphite, (ii) traces of some other contaminants such as Cr (7700 ppm), Zn (3500 ppm), Ba (3000 ppm), Pb (700 ppm) or Cu (500 ppm) on pathway soil samples that come from the steel slag, and (iii) Co (13 ppm), Pb (78 ppm) and V (54 ppm) in farmland soil samples. Although the existing heavy metals content is not appropriate for the current use, the extremely high metal contamination of the surrounding areas is more worrying. The properties of the soil farmlands (pH circa 7, 13% of clay, mainly illite, and 1-4% of organic matter content) show suitable conditions for the retention of cationic metals, but further studies on the movilization of these elements have to be performed to determine the possibility of severe human health risks. This sort of study can provide useful information for the politicians regarding the appropriate use of the territory to prevent possible health hazard for the population.

Low Levels

Environmental and occupational exposure to heavy metals should be considered an important health hazard, even more so since evidence has been provided in recent literature for toxic effects occurring even at low levels. The kidney is highly vulnerable to metal toxicity and the extent of renal damage depends on the nature, dose, route, and duration of exposure. Both acute and chronic intoxication have been demonstrated to cause kidney injury, with various levels of severity, ranging from tubular dysfunctions to severe chronic kidney disease. The epidemiology of heavy metals poisoning, their renal handling, pathophysiological mechanisms of renal toxicity, diagnosis, and monitoring, as well as therapeutic aspects are dealt with. The metals discussed include lead, cadmium, mercury, uranium, arsenic, and chromium.

Purpose: Data are available that indicate there is an elaborate elemental constitution of petroleum products, with identified elements contained in the many products being additive (e.g. Ca, Zn and P) as well as wear metals (e.g. Ag, Al, Ba, Cd, Cr, Cu, Fe, Mg, Mo, Na, Ni, Pb and Sn). In addition, incessant deliberate exposure of engine oil to both human beings and farm animals for therapeutic reason has been reported. Therefore the objective of this study is to evaluate the levels of heavy metals in serum of engine oil-exposed rats. Materials & Methods: Thirty adult female rats were divided equally into 5 groups. The first and second groups were treated with engine oil by oral route (as contaminant of feed) at dosage levels of 0.5 and 1.0 mL/kg body weight respectively. The third and forth groups received the test agent through the dermal route at dosage levels of 0.5 and 1.0 mL/kg body weight while the fifth group served as the control. The duration of the study was 30 days, after which blood was obtained from each rat, centrifuged and the resultant serum used for the analysis of heavy metals by employing Atomic Absorption Spectrometry (AAS). Data were analyzed using analysis of variance (ANOVA), p≤0.05 was considered significant. Results: Data obtained showed that there were significant differences in the levels of aluminium, silicon, cadmium, lead, arsenic, vanadium, and nickel. Conclusions: These increases suggest that incessant exposure to engine oil may be dangerous and therefore constitute health hazard.
