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 ...

Atmospheric heavy metal deposition in the Copenhagen area
Environmental Pollution (1970), 1978Abstract Atmospheric dry and wet deposition (bulk precipitation) of the heavy metals Cu, Pb, Zn, Ni, V and Fe over the Copenhagen area was measured by sampling in plastic funnels from 17 stations during a twelve-month period. Epigeic bryophytes from 100 stations in the area were analysed for the heavy metals Cu, Pb, Cd, Zn, Ni, V, Cr and Fe.

Heavy metals in atmospheric surrogate dry deposition
Chemosphere, 1999This paper describes a methodological approach for the assessment of the amount of surrogate dry deposition of several toxic heavy metals (Cd, Cr, Cu, Ni, Pb, V, Zn) associated with atmospheric particulate matter at ground level. The objectives of the study were twofold: i) the evaluation of several techniques for the digestion of dry deposition ...

Modelling the Concentration and Deposition of Heavy Metals in the UK
2014A relatively simple Lagrangian atmospheric transport model (FRAME) was adapted to simulate the concentration and deposition of nine heavy metals (As, Cd, Cr, Cu, Pb, Ni, Se, V and Zn) in the UK. The modelled data was compared with annually averaged measured wet deposition of metals and concentrations in air.

Deposition of Heavy Metals and Their Distribution on Needles and Bark
1988Three compartments of a tree: the surface layer on leaves or needles, the inner part of them, and the corresponding segments of the bark were investigated for the contents of some elements by XRFA (S, K, Ca, Ti, Mn, Fe, Ni, Cu, Zn, Br, Sr, Rb, Pb) and by INAA (Fe, Zn, Cr, Sb, Se, Co).

Heavy Metal Atmospheric Deposition Study in Moscow Region, Russia
Bulletin of Environmental Contamination and Toxicology, 2019The air quality in north-eastern part of Moscow region was evaluated by trace metals atmospheric deposition using moss Pleurozium schreberi as bioindicator. Thirty six elements were determined in analyzed samples by Neutron activation analysis and Atomic absorption spectrometry.

Effects of heavy metal deposition on soil fertility
2000Bulk deposition was collected in the vicinity of the Harjavalta smelter from 1993 to 1996 in open areas close to the Scots pine study stands using 5 rainfall collectors (O = 20 cm) during the snowfree period or 2 snow collectors (O = 36 cm) during the winter. Stand throughfall was collected using 20 rainfall collectors located systematically on the 30 ×

Equipment for heavy-metal deposition and salt dewatering
Metallurgist, 2007The composition of waste water and the requirements established for the methods used to purify it serve as the starting point in any design of water treatment facilities. As an example, the author proposes the use of a unit whose stationary drum is supplied with pre-dried sediment.

Concentrations of Heavy Metals in the Upper Volga Bottom Deposits
Water Resources, 2001The distribution of heavy metals in the Volga bottom deposits is studied. According to the degree of pollution with heavy metals, three stretches are singled out within the river reach under consideration. A drastic increase in Cu and Cd concentrations in bottom deposits is established. A close statistical correlation between Cu and Pb accumulation and
