The presence of heavy metals in the environment can be detrimental to a variety of living species including human. River crabs are sensitive to heavy metals .The concentrations of cadmium, copper, lead and zinc were analyzed in muscles, hepatopancreas, gills and exoskeletons using ICP-MS . Zinc was greater in muscles and hepatopancreas, whereas copper was greater in muscles and gills. Cadmium and lead were within the range of limits for hazardous substance about the pollution-free food. Then river crab can be an effective bioindicator for assessing metal levels in environment.

Rate Of Accumulation

The accumulation of cadmium, copper; lead and zinc in tissues of M.e.planulatus was examined at a number of metal concentrations in seawater. In every case, a linear relationship was found, in some cases after exposure to the metal for up to 86 days. The relationship between rate of accumulation of a metal over a 40- day period and its concentration in seawater was determined for each metal. From the results of field trials, it was concluded that the rate of accumulation could be used as a sensitive method of estimating concentrations of metals in seawater, with greater convenience than methods involving direct analysis. A monitoring program, in which M.e. planulatus is used to quantify levels of heavy metals in seawater; is proposed with certain limitations. The effects of extraneous parameters, both biological and physicochemical, on the accumulation of the metals were examined in relation to the ways in which they might limit the usefulness of this mussel in such a monitoring program.

The influence of heavy metals (copper, lead and zinc) associated with urban runoff, on assemblages of macrofauna in intertidal soft sediments was studied in two estuaries in the Sydney region. The patterns of distribution and abundance of fauna and assemblages was found to vary significantly at several spatial scales: within bays in an estuary, between bays within an estuary and between bays from different estuaries. Significant differences were found in concentrations of heavy metals in sediments, but there was very little difference among bays in other environmental variables: grain-size characteristics and organic matter content of sediments. Bays polluted by heavy metals had significantly different assemblages to unpolluted bays, were generally less diverse and were characterized by an order-of-magnitude greater abundance of capitellids, spionids, nereids and bivalves. Unpolluted bays had greater abundance of crustaceans and several polychaete families, including paraonids and nephtyids and were generally more diverse. There was a significant correlation between patterns of assemblages and concentrations of heavy metals, but not with other environmental variables.

Abstract. In August and September 2002, concentrations of heavy metals (copper, lead, and zinc) were 21-74% more than in previous years in Lithuanian rivers. Such a sudden increase in heavy metal pollution reduces the value of any water body for fishing or recreation and poses a potential risk to the environment and to human health. Droughts in the summer of 2002 led to forest and peat bog fires all over Lithuania and may have caused the increase in concentrations of heavy metals detected in Lithuanian rivers in August 2002. The fires could have changed the pH in the top layers of the soil, overcome geochemical barriers in the soil and enabled heavy metals to migrate from the soil to the groundwater and from river bottom sediments to the surface water.

Heavy metals in contaminated soils have benefited from a considerable attention due to the possible risks for the human body. The current study has investigated the accumulation and transfer coefficient for three heavy metals (Cu, Pb, Zn) found in the contaminated soil with three concentrations (c1=1.5%, c2=3.0%, c3=4.5%, c4=6.0%), obtained by mixing the three metals, in the tomato fruit. The highest accumulation in the tomato fruits was recorded for zinc, then copper and the smallest for lead, for all four concentrations used. The transfer coefficient decreases as the concentration of heavy metals increases, so that for high heavy metals concentrations, the values of the transfer coefficient are very low, and for small heavy metals concentrations in the soil, the values for the transfer coefficient are higher. The assessment of accumulation and transfer of heavy metals in the fruits of tomatoes grown in the contaminated soil has concluded that all concentrations of the copper, lead and zinc mix have shown a low risk for human consumption.

ABSTRACT: Angiosperms are recognized as appropriate genetic models to detect heavy metal based environmental mutagens and are used in monitoring studies. Allium cepa (onion) has been used to evaluate DNA damages like chromosome aberrations and abnormalities in the mitotic cycle. The aim of the present study is to analyze the cytotoxic effects of chromium, copper, lead and zinc in A. cepa root tip squash mitotic cell divisions. The root tips were treated with three concentrations, viz. 5, 10 and 20 mg/100 ml of chromium, copper, lead and zinc at room temperature for 24 h. Mitotic indices and chromosomal abnormalities were calculated. It was observed that these heavy metals induced different types of chromosomal abnormalities comprising of Chromosome break, Chromosome bridge, C-mitosis, Vagrant, Delayed Anaphase and Vagrant, Chromosome Loss, Polyploidy and Chromosome Bridge, Chromosome Loss and Loculated Nucles, Stickiness, Multipolarity and Polyploid prophase along with the increasing doses. The effect of chromium and lead at 20 mg/100 ml concentration was found to be more toxic rather than copper and zinc to the root meristem of A. cepa. The ranking of cytotoxic potentials was in the descending order: lead > chromium > copper > zinc.

Road runoff, a representative non-point source pollution, is known to seriously deteriorate the river water quality. In order to prevent river contamination due to road runoff, road runoff is infiltrated into the soil along the river. However, road runoff containing high concentrations of heavy metals and total petroleum hydrocarbons (TPH) can cause soil pollution. In this study, soil samples were collected at the point where road runoff flows, and the concentrations of heavy metals, such as cadmium, lead, and zinc, and TPH in them were compared with that in uncontaminated soil. Consequently, the concentration of heavy metals in the soil into which the road runoff flows was up to 21 times higher than that of the nearby uncontaminated soil. In conclusion, the discharge of road runoff into the soil seriously pollutes the soil. Therefore, direct discharge of road runoff to soil should be prevented to prevent soil pollution.

Total number of 104 canned soft drinks collected from several regions in Turkey were analysed. The purpose of this study was to determine the levels of heavy metals in the drinks commonly consumed in Turkey. Quantitative determination of heavy metals: arsenic, copper, zinc, cadmium, and lead in all samples was carried out by ICP-OES (Inductively Coupled Plasma-Optical Emission Spectrometry) method. The mean levels (± SE) of arsenic, copper, zinc, cadmium, and lead were found to be 0.037 ± 0.002 mg/kg, 0.070 ± 0.009 mg/kg, 0.143 ± 0.012 mg/kg, 0.005 ± 0.0003 mg/kg, and 0.029 ± 0.002 mg/kg, respectively, in soft drinks. Our data revealed that arsenic, copper, zinc, cadmium, and lead mean levels found in all soft drinks, collected from several regions in Turkey, were within the Turkish Food Codex (TFC) values.

Vertical profiles of trace metal levels in the water column for 16 oceanographic stations around Tasmania were determined using anodic stripping voltammetry (ASV) at a mercury-coated graphite electrode (MCGE), a rotating disc glassy carbon electrode (RDGCE) and atomic absorption spectrophotometry (AAS). Cadmium, copper, lead, and zinc were determined by ASV, and iron and nickel were determined by AAS. Variation occurred between MCGE and RDGCE results in the samples analysed for cadmium, copper, lead, and zinc. Statistical analyses of the concentrations found indicated that variations were more likely to be due to procedural blank fluctuations than to change in concentration with depth. For the AAS analyses of nickel, some variation in concentration with depth was apparent after consideration of procedural blanks. However, this variation follows a random scatter pattern.

In the present study, the occurrence of some heavy metals was determined in muscle, liver and kidney tissues of cattle in Burdur, Turkey. The samples were analyzed for cadmium, lead, arsenics and mercury using Inductively Coupled Plasma-Optical Emission Spectrometry in 50 samples. Concentrations of Cd exceed the permissible limits in 2 samples of muscle tissues (0.05 mg/kg), while the concentrations of Cd in the liver and kidney tissues were below the allowed limits (0.5 mg/kg for liver; 1.0 mg/kg for kidney). One sample in muscle tissue contained Pb above the allowed limit (0.1 mg/kg). Arsenic was detected in one sample of muscle, liver and kidney tissues. Hg was not detected in any of the samples. A high proportion of samples did not contain detectable level of the heavy metals. Except for Cd and Pb in muscle tissue, concentrations of other metals were below the permissible limits.

This review gives insights into the levels of metals in urban dust, their determination methods, and risk assessment. Urban dust harbors a number of pollutants, including heavy metals. There are various methods used for the sampling of urban dust for heavy-metal analysis and source-apportionment purposes, with the predominant one being the use of plastic sampling materials to avoid prior contamination. There are also various methods for the determination of metals, which include: atomic absorption spectroscopy (AAS) and inductively coupled plasma-mass spectrometry (ICP-MS), among others. Studies have shown that pollutants in urban dust are mainly derived from industrial activities and coal combustion, whereas traffic emissions are also an important, but not a predominant source of pollution. The varying particle-size distribution of urban dust and its large surface area makes it easier for the deposition and transport of heavy metals. Risk-assessment studies have shown that metals in urban dust could cause such problems as human pulmonary toxicity and reduction of invertebrate populations. The risk levels seem to be higher in children than adults, as some studies have shown. It is therefore important that studies on metals in urban dust should always incorporate risk assessment as one of the main issues.
