Preliminary Study

Soil is a complex matrix and a major reservoir of contamination. It can bind many potential toxicelements such as heavy metals, and they can exist in various forms. The main objective was tocharacterize the soil sample in relation to heavy metal concentrations in the Tanah Merah wastedumping site. Soil samples were taken from three different locations around the waste dumping siteand determined by Atomic Absorption Spectrophotometry (AAS) for Cu, Fe and Zn determination.High concentrations of Fe (9.18 mg/L) as compared to Cu (0.53 mg/L), and Zn (0.49 mg/L) werefound in the soil samples but were lower than previous studies. However, early precautionaryactions need to be implemented since a higher volume of waste disposal in the future might causechanges in heavy metals intensity at the waste dumping site.

This study reports the determination of some heavy metals’ concentration in soil and groundwater around refuse dumpsites in five locations in Ibadan Metropolis, Nigeria. Five samples were collected from each soil and ground water locations and analysed for heavy metals(Cd, Co, Pb, Cr, Zn, Mn and Ni)using Atomic Absorption Spectrophotometry. The soil samples were obtained in triplicates at 25cm depth intervals whereas the water samples were obtained from hand dug wells less than 10 m deep. The range of the values of heavy metal concentrations obtained in water is Co (0.01-0.04), Pb (0.01-0.02), Cr (0.02-0.05), Zn (0.40-0.70), Mn (0.02-0.05) and Ni (0.02-0.05), but Cadmium was not detected. The concentrations of Pb and Ni in ground water obtained from Arapaja, Aleshinloye and Alafara were higher than the World Health Organization (WHO) and Standard Organisation of Nigeria (SON) limits. The results obtained showed that the concentrations of Cd, Co, Pb, Ni and Cr in soil exceeded the WHO and SON permissible limits. However, Zn and Mn were below the limit.

Heavy Metals In Soils

This study attempted to evaluate the efficiency of zeolite and pyrophyllite ore materials in reducing the mobility of heavy metals in soil near the lignite mining dumps, and consequently in their availability for plants. Extraction of pseudo-total and available forms of heavy metals from soil samples was performed by using aqua regia and ethylenediaminetetraacetic acid, respectively. Concentrations of heavy metals in soil and plant samples were determined by atomic absorption spectrophotometry. The results of this study illustrate that application of zeolite and pyrophyllite could be a suitable technique to reduce heavy metals availability in soils. Zeolite treatments have been shown to be significantly effective in reducing cadmium (Cd) mobility, as well as pyrophyllite treatments in reducing lead (Pb) mobility in the studied soil, regardless of applied rates. The accumulation of heavy metals in leaves of maize grown on soil plots treated by zeolite and pyrophyllite, was found to be lower compared to the untreated plots. This finding was to be expected, considering the effects of these treatments on heavy metals mobility in the studied soil.

ABSTRACT The present study aimed to determine heavy metal concentrations in the tree bark of the species Poincianella pluviosa in Volta Redonda municipality, Rio de Janeiro. Four sets of barks of eight trees with three replicates each from sectors 1 (W), 2 (S), 3 (E), and 4 (N) of the Volta Redonda center corresponding to the cardinal points were collected. The samples were digested in a nitroperchloric mixture and the lead (Pb), cadmium (Cd), nickel (Ni), copper (Cu), zinc (Zn), iron (Fe), and manganese (Mn) contents were determined by atomic absorption spectrophotometry. The cluster analysis (CA) formed 12 groups; among them, group 3 (G3) showed the presence of all seven elements in sector 1 and group 8 (G8) showed the presence of Pb, Zn, Fe, Ni, and Mn in sector 2. Kruskal-Wallis and Bonferroni tests showed that all elements presented statistically different values among the four sectors when compared with each other (p > 0.05). Sectors 1, 2, and 3 had the highest concentrations of heavy metals, which are directly associated with vehicle and railroad flow and iron and steel activities that are concentrated in these sectors. Bark can be used as an effective method for the monitoring of air pollution in urban areas.

Abstract This study was carried out to assess the levels of heavy metals, polycyclic aromatic hydrocarbons (PAHs), and antioxidants present in pumpkin leaf (Telfairia occidentalis), catfish (Clarias anguillarus), and African land snail (Archachatina marginata), obtained from Ebubu and Elele-Alimini communities in Rivers State, Nigeria. The heavy metals and PAHs were analyzed using Atomic Absorption Spectrophotometry (AAS) and gas chromatography respectively, while the antioxidants were assayed by conventional methods. Soil samples at Ebubu contained significantly higher Pb, Cr, Cd, and Ni contents than that of Elele-Alimini. The pumpkin leaf from Elele-Alimini contained higher Pb, Zn, Cd, and Fe levels. Cr was undetected in the snails from both locations, while Cd and Ni contents of the snails and catfish at both communities were comparable. For the PAHs, the soil samples from Ebubu contained mostly anthracene (93.37 ppm), benzo[k]fluoranthene (74.36 ppm), fluoranthene (72.64 ppm), and acenaphthylene (47.38 ppm), while those from Elele-Alimini contained more of dibenz[a,h]anthracene (38.65 ppm) and naphthalene (20.55 ppm). Pumpkin leaves from Ebubu were mostly composed of naphthalene, indeno[1,2,3-cd]pyrene, and dibenz[a,h]anthracene, which were undetected in pumpkin leaf samples from Elele-Alimini. In the snail and catfish from Ebubu, acenaphthylene and fluoranthene respectively were the most occurring PAHs, whereas pyrene and phenanthrene respectively had the highest occurrences in snails and catfish from Elele-Alimini. Results for the antioxidant enzymes: catalase and superoxide dismutase in both snails and catfish from Elele-Alimini were significantly higher than those from Ebubu whereas samples from Ebubu contained significantly higher glutathione and malondialdehyde levels. The level of toxicants shown in the foods analyzed in this study is suggestive of potentials to pose significant health risks to the populace when consumed.

The bioaccumulation of the heavy metals Cu, Zn, Fe and Pb was determined in the livers, kidneys and muscles of Oncorhynchus mykiss trout at seven production centers in the province of Yauli, Junín-Peru. The determination and quantification of total heavy metals in water samples collected monthly from the production sites and in 28 trout that averaged 250 g and 27 cm was performed by atomic absorption spectrophotometry, according to the methodology recommended by FAO. Levels of Zn, Fe and Pb were found to exceed the environmental quality standards established by the Peruvian Ministry of the Environment for the rivers of the coast and highlands, as well as the quality standards of the European Union for the cultivation of trout, while levels of Cu conformed with those standards. Concentration of Cu, Zn, Fe and Pb in the livers, kidneys and muscles exceeded the maximum permissible limits established by the European Union for fish meat and by the Mexican official standard, NOM-027-SSA1-1993, for fresh, refrigerated and frozen fishery products, in the case of Pb. The correlation between the concentrations of copper, zinc, iron and lead in the water and the concentrations of these metals in the livers, kidneys and muscles is low and not significant, except for copper, which had a significant correlation.

Abstract The effect of alcohol and sugar concentration on the atomic absorption analysis of copper, zinc, nickel, chromium, lead, cadmium, and cobalt has been investigated. Sugar reduced the sensitivity of analysis but could be compensated for by using the method of additions. Interference from alcohol was avoided by introducing an evaporation stage, and the concentration of the above cations was determined by direct aspiration in 24 native and imported wines.

Various essential and toxic heavy metals (Ca, Mg, Cu, Zn, Fe, Mn, Pb, Cd, Cr, and Ni) contents in various types of dried (infant formulaandpowdered) and fluid (freshandprocessed) cow milk were assessed by atomic absorption spectrophotometry. The milk samples were collected from local markets of different parts of Peshawar city, Pakistan. Heavy metal concentrations varied significantly depending upon the type of milk. The heavy metal concentrations in most of the samples were within normal and permissible ranges. It was observed that the samples contained considerable amounts of calcium, while magnesium levels were well above the required levels. The results also revealed that copper levels were slightly lower than the permissible limits. The concentration of zinc in dried milk samples was greater than the values for the liquid milk types. Infant milk formulae had higher iron levels as compared to other milk samples because of the added constituents. Significant differences were observed in the mean values of manganese and cadmium in different types of milk. The toxic metals were within the acceptable limits and did not show significant levels leading to toxicity.

A significant flux of heavy metals, among other toxins, reaches the lungs through smoking. This study reports Cd, Pb, Cu and Zn contents in tobacco of 11 brands of cigarette commonly sold in Ethiopia. The heavy metals were determined by atomic absorption spectrophotometry after wet digestion of cigarette tobacco using HNO3 and H2O2. The concentration of trace metals in the cigarettes ranged (mean) (μg/g), Cd: 1.3−7.6 (2.48±0.32), Pb: 0.50−12.50 (6.24±2.2), Cu: 2.89−25.35 (13.70±4.12) and Zn: 24.40−62.55 (36.22±7.50) while Ni was not detected in all the eleven brands of cigarettes. Comparable levels of trace metals were obtained in the tobacco of both imported and Ethiopian cigarettes. The average trace metal contents of cigarettes available in Ethiopia were Cd 1.82±0.39, Pb 4.23±0.97, Cu 10.2±3.1 and Zn 28.2±7.8 μg/cigarette and a person who smokes 20 cigarettes per day is estimated to increase his/her daily Cd, Pb, Cu and Zn retention by approximately 0.036, 0.085, 0.204, 0.564 mg/day, respectively. The results indicate that smoking and exposure to cigarette smoke is a serious problem to be taken into account when carrying out epidemiological studies on human exposure to trace metals.
