In general, wild mushrooms are considered are an excellent source of valuable nutritional compounds but can exerttoxic potential due to the accumulation of heavy metals. In the present study the basic physicochemical composition (fat, protein, and moisture) and heavy metal content profile (Pb, Cd, Cs) of two popular edible wild mushrooms of the species Boletus edulis and Cantharellus cibarius harvested from the forests of Vatra Dorna, Romania were determined. Both investigated mushrooms samples demonstrated a good protein source with the means ranged from 1.58-2.91. In addition,analyzed mushrooms showed a low-fat content presenting values of 0.41- 0.45. Inductively coupled plasma massspectrometry technique (ICP-MS) presents heavy metal content from B. edulis and C. cibarius samples ranged from 0.9 - 0.12 for Pb and 0.16 - 0.25 for Cd, respectively

A high content of heavy metals in the soil and plants of a magnesite mining area might cause serious damage to the environment and can be a threat to the health of the surrounding population. This paper presents the results of research that focused on analyzing the heavy metal content in soil and plants in the dumping grounds of the magnesite mining factory Jelšava-Lubeník (Slovakia). The analysis focused on the content of heavy metals in soil (X-ray fluorescence spectrometry, atomic absorption spectrometry), in plants (inductively coupled plasma mass spectrometry, inductively coupled plasma atomic emission spectrometry), and pH (1M KCl solution). The results showed that the soil in the study area was slightly acidic to strongly alkaline and the content of Cr, As, Mn, and Mg exceeded by several times the limit values for the Slovak Republic. The results of the hierarchical cluster analysis and the correlation analysis show that the grouped metals come from the same sources of pollution. The content of heavy metals in plants was high and the highest concentration was found in the roots of Elytrigia repens > Agrostis stolonifera > Phragmites australis and flowers of Phragmites australis. The findings confirmed the suitability of the used plants in the process of phytoextraction and phytostabilization. The acquired knowledge can help in planning and realization remediation measures and improve the state of the environment in areas exposed to magnesite mining.

Waste wood collected at the Vancouver landfill has been sorted based on the visibility of coatings, paints, and the green colorization of wood typically associated with wood preservatives. The sorted material was then ground and tested with an inductively coupled plasma mass spectrometry (ICP–MS) for heavy metal elements that are toxic or harmful to humans and (or) the environment. Results indicated that wood preservatives were not visually detectable but paints and coatings were. Therefore, the study demonstrated that visual sorting is not sufficiently accurate to distinguish between treated and clean or untreated waste wood.

Background: Hazardous materials, such as used batteries contain heavy metals and enter the solid waste stream, ending up in landfills. The present study was done to determine the amount of used batteries in Iran and their heavy metal contents in the batteries entering the landfill site in Tabriz. Methods: A questionnaire was applied to assess the current management condition of the used batteries in Tabriz and Ardabil as the representative cities of the entire country. The heavy metal content of 15 AA-sized batteries was determined by inductively coupled plasma. Results: Our findings showed that 14.7% of the used batteries in Iran have been imported, and approximately 76% and 24% of the batteries analyzed at the landfill site were AA-sized and cellphone batteries, respectively. In 60% of the studied batteries, the total heavy metal content was less than 100 mg/kg. Conclusion: The results of this study could be a useful reference for global and local policymakers in developing effective regulations for the use of cleaner materials in the battery industry and controlling the used batteries from their generation to the end of the battery life

The metal contents of 19 tea leave samples, Camellia sinensis L., from Yen Bai and Tuyen Quang provinces were determined using inductively coupled plasma optical emission spectrometry (ICP-OES) and atomic absorption spectrometry (AAS). Total 18 elements in tea leaves were determined including macroelement such as Al, Ca, K, Mg, Mn; trace element such as Na, Ba, Fe, Cu, Sn, Zn, Se, Ni, B and heavy metal (Pb, Hg, Cd and metalloid As). The results show that, K content was the highest among the macroelement, followed by Mg, Ca, Mn and Al. There was a wide variation of the trace metal content among the tea leaves coming from different province. The levels of heavy metal content in most of the samples were not detectable or below the acceptable level as required by Ministry of Health.

Heavy metal contaminants in fish are of particular interest because of the potential risk to humans who consume them. The edible muscles of eight different species of fishes were analyzed by ICP-MS (Inductively Coupled Plasma Mass Spectroscopy) for heavy metals, collected from Market in Gwangju, Korea during April-May in 2008. The concentrations of Hg, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn varied between 0.24±0.007 - 0.01±0.001, 44.54±5.69 - 1.23±0.20, 0.13±0.05 – ND (not detected), 1.32±0.47 - 0.09± 0.02, 3.13±2.53 - 0.63±0.06, 107.17±28.02 - 11.27±1.56, 12.38±1.23 - 0.25±0.02, 1.025±1.41 - 0.12±0.09, 0.74±0.28 - 0.05±0.03 and 80.30±17.09 - 22.35±6.89 mg/kg, respectively. The concentrations of arsenic and nickel exceeded the maximum allowable intake level. Keywords: Heavy metals; Marine fish; Korea. © 2010 JSR Publications. ISSN: 2070-0237 (Print); 2070-0245 (Online).
