Heavy metal deposition in Scandinavia
Water, Air, and Soil Pollution, 1973Maps showing the regional differences in the atmospheric deposition of Pb, Cd, Hg, Cr, Ni, Cu, Zn, and Fe have been prepared for Finland, Norway and Sweden from data obtained by means of moss analysis, a method previously shown to be a sensitive and reliable tool in measuring heavy metal deposition.

Monitoring of heavy metal deposition in Northern Italy by moss analysis
Environmental Pollution, 2000A survey of heavy metal deposition in the mountainous territories of Northern Italy was carried out in 1995-96. Moss samples (mainly Hylocomium splendens) were collected in a dense network of sites (about 3.2 sites/1000 km(2)) and the data of metal concentrations in moss tissues were statistically correlated with environmental and climatic factors, as ...

Deposition of heavy metals in biological tissues of workers in metal workshops
Environmental Science and Pollution Research, 2022Welding and cutting of metals produce large amounts of particulate matter (PM), which poses a significant health risk to exposed workers. Appropriate biological markers to estimate exposure are of great interest for occupational health and safety. Here, hair and nail samples from metal workers were analyzed, which appear to be more suitable than blood ...

Heavy Metal Concentrations in Plants in Relation to Atmospheric Heavy Metal Deposition
Journal of Environmental Quality, 1995AbstractZinc, Cu, Pb, and Cd concentrations were examined in several plant species and corresponding organic topsoil collected in forest and on ombrotrophic bogs along a temporal (1982–1992) and a spatial (Southern Norway‐Central Norway) heavy metal deposition gradient.

Solubility of deposited airborne heavy metals
Atmospheric Research, 2008Abstract Toxic effects of heavy metals in water and soil environments are important. Quantifying the heavy metal concentrations and their solubilities in dry and wet deposition samples is part of atmospheric research. Soluble fractions of the deposited air pollutants are important in food chain mechanisms as heavy metals may cause ecotoxic impacts ...

Acid deposition and heavy metal mobilization
Applied Geochemistry, 1996Abstract During the Third International Symposium on Environmental Geochemistry held at Krakow, Poland in September 1994, a Workshop was held on “Acid Deposition and Heavy Metal Mobilization” which was sponsored by the European Environmental Research Organization (EERO).

Heavy metal sulphide deposits and geochemical surveys for heavy metals in New Zealand
Journal of the Royal Society of New Zealand, 1985Abstract The ultimate primary source of heavy metals in the environment is crustal rock and the mineral deposits it contains. Background levels in the earth’s crust of the main “toxic” heavy metals lie in the ranges of: lead, 1–20 ppm; cadmium, 0.01–0.03 ppm; mercury, 0.01–0.09 ppm; and arsenic, 1–13 ppm.

Response of mosses to the heavy metal deposition in Poland — an overview
Environmental Pollution, 2001Concentrations of heavy metals (Cd, Cr, Cu, Fe, Ni, Pb, Zn) in Pleurozium schreberi (Brid.) Mitt., a common moss species, were used to indicate relative levels of atmospheric deposition in Poland in the years 1975-1998. Spatial and temporal differences in the heavy metal concentrations in mosses were found. The highest concentration of heavy metals was

Wet Deposition of Heavy Metals
1989Macroscale and microscale processes of removal of atmospheric metals from the atmosphere by precipitation and fog water deposition are described. Methodologies for measuring wet deposition are critically examined. Finally, pitfalls in using historical measurements of metals deposition and scavenging ratios to estimate removal are discussed.

Atmospheric heavy metal deposition in agro-ecosystems in China
Environmental Science and Pollution Research, 2017Atmospheric deposition has become one of the main sources of heavy metals in crops in developed and industrial zones in China for the past several years. However, lack of data of the agro-ecosystems on the vast areas of China makes it difficult to assess the impacts of air pollution on the heavy metal accumulation in crops.
