This paper analyses manganese content in the air, in the soil and in the vegetative parts of seven tree species at seven localities. Soil and plants contaminated by heavy metals can cause environmental risk and cause health problems. Heavy metals are substances which signalize environmental pollution. Within the study of other heavy metals (lead, nickel, zinc and iron), manganese content was analyzed in some tree species depending on the concentrations of manganese in the soil and air in the National Park "Fruska Gora", along the road M-21.

Background: The present study investigated the concentrations of lead, nickel, copper, zinc, their toxicity potential, and their ecological hazard in surface soils of Hamedan City, Iran. Also, using the Bio-concentration Factor (BCF), concentration Comprehensive Bio-concentration Index (CBCI), and Metal Accumulation Index (MAI), was evaluated the ability of some tree and shrub species to absorb heavy metals in soil and air. Methods: Sampling of leaves of nine tree species and shrubs (plane, acacia, elm, willow, mulberry, ash, redbud, pine, and cypress) was performed in six stations. After preparation and acid digestion of the samples, the concentrations of heavy metals were determined using an atomic absorption spectrometer. Results: The trend of changes in soil heavy Mean±SD metal concentrations was in the order of nickel> zinc> copper> lead in the amounts of 61.41±11.34˃ 43.04±14.4˃ 42.87±8.36˃ 18.77±6.51 mg/kg. Evaluation of acute toxicity potential indicators and ecological risk of heavy metals indicated low soil pollution status. Findings of BCF, CBCI, and MAI ndices in the leaves of the species showed that the highest levels of BCF of heavy metals, i.e., zinc, copper, lead, and nickel, were in willow, elm, cypress, and pine species, respectively. Results show that heavy metal accumulation in different species. Conclusion: Depends on soil type, tree species, climatic conditions, type of pollutant source, species age, and other factors. In this study, elm and acacia have the highest ability to absorb heavy metals from soil and air.

The aim of this study was to determine the effect of the age of trees, daily sap volume as well as the term of tapping birch sap collected in the forest environment on the content of selected minerals (zinc, copper and manganese) and heavy metals (lead, nickel, chromium and cadmium). The study was performed on material taken from two stands (aged 34 and 84 years) in a moist broadleaved forest habitat with a dominant share of silver birch (Betula pendula Roth). The research results confirmed the presence of both nutritional essential minerals and hazardous heavy metals in the birch sap. At the same time, the content of minerals and heavy metals was found to be very variable and the differences between their concentrations, recorded on the same day of collecting in several trees of the same age group, can be even several dozen times higher. Depending on the examined elements, the factors influencing their content vary. The age of the trees determines only the manganese content; daily sap volume significantly affects the content of manganese and copper, and date of collection differentiates the content of zinc, lead, nickel and cadmium. The results may be interesting in the context of developing procedures for collecting birch sap for the purpose of obtaining raw material with beneficial nutritional values and a high level of health safety. For this reason, our recommendation for guaranteeing the health safety and high nutritional value of birch sap is to combine batches of raw material taken from as many trees as possible, and at the same time to publicize the fact that collecting birch sap from just one single tree may result in a raw material that is both dangerous and has no nutritional benefits.

We conducted a preliminary field study that examines the accumulation of Pb, Cd, Zn, Mn, and Cu in plants and soil along a roadway in Zion National Park. The study is designed to determine the effects of motor traffic on the accumulation of these heavy metals in various plant species and soil during 1 year and to determine if these accumulations decrease as you move away from the roadway. Preliminary results indicate that the amount of Pb, Cd, Zn, Mn, and Cu concentrations found are a function of the number of vehicles passing during a year and the distance from the roadway. Higher concentrations of these heavy metals are found in areas close to the road and in areas where traffic is moving slowly or even stopped. The heavy metal concentrations decreased as the distance from the roadway increased, and the speed of passing vehicles increased.

Heavy metals contamination in groundwater often occurs in various industrial processes. Stud-ies have confirmed that polysulfide could reduce hexavalent chromium to trivalent chromium, achieving the effect of in-situ stabilization. For other heavy metals contamination in groundwa-ter, whether polysulfide also had a stabilizing ability to achieve in-situ remediation. This re-search focused on heavy metals except for chromium that often contaminated in groundwater, including lead, nickel, zinc, copper, and cadmium to explore the feasibility of using calcium polysulfide (CaSx) as an in-situ stabilization technology for these heavy metals contamination groundwater. Results showed that CaSx had a great removal efficiency for heavy metals lead, nickel, zinc, copper, and cadmium. However, for nickel, zinc, copper and cadmium, when CaSx was added excessively, complexes would be formed, causing the result of re-dissolve and this would also reduce the removal efficiency. Since it is difficult to accurately control the dosage of agents for in-situ groundwater remediation, the concentration of re-dissolved nickel, zinc, cop-per, and cadmium may not be able to meet the groundwater control standards. CaSx had high lead removal efficiency, and it would not cause re-dissolution due to excessive CaSx dosing. CaSx can be used as an in-situ stabilization technique for lead contaminated groundwater.

Abstract. Roe deer Capreolus capreolus has often been mentioned in the literature as a good bioindicator of environmental pollution. To find out the levels of heavy metals (Cd, Pb, Hg, As, Zn) in roe deer tissues, this research project was begun near metallurgic and electricity generating centres of Slovenia in 1997. The results of the first sampling year reveal that metal burdens are the highest in the Koroška region, an industrial area in the northern part of Slovenia with a centuries-old tradition of mining and processing of lead ore. Levels (expressed on a wet weight basis) of Cd (2.91 ± 2.92, 7.13 ± 4.43 and 22.7 ± 8.92 mg kg−1 for fawns, yearlings and adults, respectively), As (0.23 ± 0.03 mg kg−1) and Zn (47.1 ± 8.26 mg kg−1) in kidneys as well as levels of Pb (0.71 ± 0.65 mg kg−1) in liver of animals shot in the Koroška region significantly exceed the levels measured in other Slovenian regions. On the contrary, metal levels in viscera of roe deer from the Šalek Valley (where the major Slovene power plant of Šoštanj is located) are low (0.14 ± 0.01, 38.2 ± 4.39 and 0.02 ± 0.03 mg kg−1 for As, Zn and Hg in kidney; 0.21 ± 0.04 mg kg−1 for Pb in liver, respectively). Relatively high levels of Hg (0.23 ± 0.09 mg kg−1; six- to tenfold higher compared to other areas of interest) in kidneys and Pb (0.55 ± 0.13 mg kg−1) in liver of animals shot in the control area of the Triglav National Park, which represents the area without any local emission sources, demonstrate the possibility that animals are being exposed to contaminants that we would not have expected from other data. Consequently, the value of roe deer as an accumulative bioindicator of environmental pollution with heavy metals is clearly confirmed.

The Impact

This paper discusses the derivation of environmental quality standards for coastal waters and the difficulties of using such standards for controlling industrial discharges. Attention is focused on the common List II substances, copper, chromium, lead, nickel, zinc and arsenic - and their effects on marine life. The adequacy of existing toxicity data is discussed and it is concluded that long exposure tests are required to provide information on sublethal effects. Such data are currently limited. It is also important that consideration be given to the effects that reducing salinities and increasing temperatures have in increasing the toxicity of these substances. The complexity of interpreting the results of laboratory toxicity data to coastal waters is discussed with reference to a study of the impact of an industrial discharge.

AbstractThis study was undertaken to examine changes in the content of pigments and accumulation of metals from vehicular pollution in selected species of roadside trees under vehicular pollution. A major arterial road with heavy vehicle emissions in the Kumasi Metropolis was designated as the polluted site, while Kwame Nkrumah University of Science and Technology Campus was designated as the control site. Four tree species (Terminalia catappa, Mangifera indica, Ficus platyphylla and Polyalthia longifolia) selected for the study were well distributed and abundant in the polluted and control sites. Photosynthetic pigments and levels of heavy metals (Pb, Cu, Cd and zinc) were assessed in their leaves. Chlorophyll and carotenoid contents were determined by absorption spectrometry, while the metal accumulation index (MAI) was used to determine the total metal accumulation capacity of the tree species. We observed a reduction in photosynthetic pigments in the leaf samples from the polluted site. Ficus platyphylla had the maximum reduction in total chlorophyll (49.34%), whereas Terminalia catappa recorded the lowest reduction (33.88%). Similarly, the largest decrease (31.58%) of carotenoid content was found in Terminalia catappa trees and the lowest in Polyalthia longifolia (16.67%). The Polyalthia longifolia, Ficus platyphylla and Terminalia catappa leaf samples collected at the polluted site recorded a higher ratio of chlorophyll a/b. Heavy metal (Cu, Pb, Zn and Cd) accumulation in leaf samples was higher in the polluted site than in the control, as expected. The highest metal MAI value was recorded in Mangifera indica (5.35) followed by Polyalthia longifolia with 4.30. The findings from this study specifically demonstrate that air contamination induced by vehicles decreases the level of photosynthetic pigments in trees subjected to roadside emissions. It is clear that both chlorophyll a/b and chlorophyll/carotenoid ratios will act as very useful stress-level markers. Elevated heavy metal levels in the tree species along arterial roadsides indicate that they serve as heavy metals sink. The change in MAI resulting from different pollution burden is an indication that the removal capabilities of the tree species differ from each other. We therefore suggest M. indica and P. longifolia as potential species to be used in air pollution reduction plans in the city.
