The objective of this preliminary study was to evaluate the levels of selected heavy metals in hair samples of Holstein dairy cows reared on agricultural soils characterized by grassland subjected to anthropogenic impacts. Ninety Holstein-Friesian cows were enrolled in the study and divided into six groups according to farm origin. From each animal, hair samples were collected in order to determine the content of aluminum, chromium, iron, copper, zinc, arsenic, cadmium, and lead. One-way analysis of variance was applied to assess statistically significant differences in the studied heavy metals among the six groups. A significant effect of groups (p < 0.05) on all tested heavy metals was observed. In this study, the low concentration of heavy metals in the hair of the studied animals led us to think that the cows were subjected to low levels of these compounds, preventing them from bioaccumulating. Although the current study provides only preliminary results, it highlights the importance of investigating the concentration of heavy metals in cow hair to improve the health and welfare of both humans and animals.

River Kabul

The contamination of aquatic systems with heavy metals is affecting the fish population and hence results in a decline of productivity rate. River Kabul is a transcountry river originating at Paghman province in Afghanistan and inters in Khyber Pakhtunkhwa province of Pakistan and it is the major source of irrigation and more than 54 fish species have been reported in the river. Present study aimed at the estimation of heavy metals load in the fish living in River Kabul. Heavy metals including chromium, nickel, copper, zinc, cadmium, and lead were determined through atomic absorption spectrophotometer after tissue digestion by adopting standard procedures. Concentrations of these metals were recorded in muscles and liver of five native fish species, namely,Wallago attu,Aorichthys seenghala,Cyprinus carpio,Labeo dyocheilus, andOmpok bimaculatus. The concentrations of chromium, nickel, copper, zinc, and lead were higher in both of the tissues, whereas the concentration of cadmium was comparatively low. However, the concentration of metals was exceeding the RDA (Recommended Dietary Allowance of USA) limits. Hence, continuous fish consumption may create health problems for the consumers. The results of the present study are alarming and suggest implementing environmental laws and initiation of a biomonitoring program of the river.

Abstract The aim of the research was to assess the level of contamination with heavy metals (manganese, iron, nickel, copper, zinc, cadmium and lead) in two forest areas selected in different places in Poland: the first one in the Swietokrzyskie Province (forests of the Staporkow Forest Division) and the second one in the Opolskie Province (forests of the Kup Forest Division). The degree of contamination of these forest areas with analytes was found using edible large-fruited mushrooms naturally occurring there - the research was carried out using passive biomonitoring method. Heavy metals in mushrooms (separately in stems and hats) as well as in soil samples were determined by atomic absorption spectrometry with excitation in flame (F-AAS). The obtained results were interpreted by assessing the degree of contamination of forest areas on the basis of concentrations of heavy metals in mushrooms. The obtained results indicate an increased accumulation of heavy metals in hats than in mushrooms stems. On the basis of the obtained data, significant contamination of forest areas with selected heavy metals was also found. This is confirmed by the possibility of using mushrooms as biomonitors in passive biomonitoring of forest areas, which are heavy metal accumulators. In the interpretation of the test results, the phytocumuling factor (PF) was also used. The degree of accumulation of heavy metals, from given forest areas - from soil to mushrooms - was assessed on the basis of determined PF coefficients. In addition, good bioavailability of the analysed analytes by mushrooms was found. Additionally, on the basis of the conducted studies, the possibility of mushroom consumption was assessed - they are not suitable for consumption due to the fact that the permissible concentration standards of heavy metals contained in mushrooms were exceeded.

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.

The tentative permissible concentrations and the maximum permissible concentration of heavy metals do not always give a complete adequate assessment of the effect on plants. Plant growth inhibition can be at concentrations below the maximum permissible concentrations and tentative permissible concentrations. We studied the effect of copper, zinc, cadmium, and lead concentrations on plants. The object of the research is the lawn grass, the Agrostis stolonifera used in urban greening. According to the data obtained, Agrostis stolonifera showed a low degree of resistance to copper, lower than the tentative permissible concentration and the maximum permissible concentration. Consequently, the tentative permissible concentration and the maximum permissible concentration do not fully reflect the real phytotoxicity of copper. Plants of Agrostis stolonifera demonstrated a relatively high sensitivity to zinc in comparison with the maximum permissible concentration and the tentative permissible concentration. The content of cadmium and lead corresponding to the tentative permissible concentrations did not have a significant effect on the plants.

Physical, chemical and bacteriological analyses were carried out of water samples from three boreholes located near a landfill, and or soil samples at Akure, Nigeria, to ascertain the effect of the dumpsite on the groundwater and soil quality. The samples from borehole locations with radial distances of 50, 80, and 100 m, respectively, away from the landfill and twelve soil samples collected at distances 0 (dump centre), 10, 20, and 30 m away from the refuse dump were analysed. The parameters determined were the turbidity, temperature, pH, dissolved oxygen (DO), total dissolved solids (TDS), total hardness (TH), total iron, nitrate, nitrite, chloride, calcium and heavy metals like copper, zinc, and lead. Most of these parameters indicated pollution but were below the World Health Organization (WHO) limits for consumption. The pH ranged from 5.7 to 6.8 indicating toxic pollution, the turbidity values were between 1.6 and 6.6 NTU, and the temperature ranged from 26.5&deg;C to 27.5&deg;C. The concentrations of iron, nitrate, nitrite and calcium ranged from 0.9 to 1.4, 30 to 61, 0.7 to 0.9, and 17 to 122 mg/l, respectively. Out of heavy metals, zinc ranged between 3.3 and 5.4 mg/l and lead ranged from 1.1 to 1.2 mg/l. Soil water holding capacity, porosity, pH, organic matter, organic carbon and organic nitrogen ranged from 38 to 54, 44 to 48, 6.9&ndash;7.5, 2.44&ndash;4.27, 1.42&ndash;2.48, and 0.12&ndash;0.21%, respectively. Statistical analyses indicated significant differences at 95% level. The results showed that all the boreholes were not strongly polluted but require treatment before use while the soil is absolutely unsuitable for the crop production. Re-designing of sanitary landfills to prevent leachate from getting to the water table, adoption of clean technology for recycling greenhouse gases and a sustainable land management programme for reclamation are recommended.

The aim of the present study is to investigate the bioaccumulation and translocation of various heavy metals, notably copper, zinc, cadmium and lead, in the different plant organs of Trapa natans L. (the root, stem, and leaf) at nine sampling locations, as well as examining the variability in proline accumulation and chlorophyll content due to these heavy metals. Our analysis shows the existence of a statistically significant positive correlation (r = 0.75; p < 0.05) between the Zn content and the accumulation of proline in the root of the examined species. On the other hand, a statistically significant negative correlation was registered between the content of chlorophyll a and the concentration of Zn in the leaf (r = −0.68; p < 0.05). This indicates that Trapa natans L. can be used in biomonitoring Zn-polluted aquatic ecosystems using proline and chlorophyll as sensitive biomarkers.

Mn co-precipitation method combined with Raman spectroscopy were used to determine trace heavy metals (copper, zinc, cadmium and lead) in water sample. Different concentrations of heavy metals including copper, zinc, cadmium and lead in water samples were separated and enriched by Mn 2+-phen-SCN- ternary complex co-precipitation procedure. The Raman spectra of co-precipitation sediments were collected using confocal micro-Raman spectrometry. Different preprocessing treatments and regression calibration methods were compared. The best models using partial least squares regression (PLS) of copper, zinc, cadmium and lead were built with a correlation coefficient of prediction (Rp) of 0.979, 0.964, 0.956 and 0.972, respectively, and the root mean square error of prediction (RMSEP) of 6.587, 9.046, 9.998 and 7.751 μg/kg, respectively. The co-precipitation procedure combined with Raman spectroscopy method are feasible to detect the amount of heavy metals in water.
