“…3 Different local legislation usually defines the acceptable levels for total content of potentially toxic metals. [4][5][6] This type of information is of limited value, because the actual environmental impact of the elements would depend on the mobility, bioavailability and toxicity of their specific physicochemical forms in compost. Furthermore, the low availability of heavy metals for soils and plants have been observed 7 and even the application of compost to the remediation of metal-contaminated soils was suggested.…”

In this work, the speciation of elements in compost was studied with emphasis on their binding to humic substances. In order to assess the distribution of As, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb, U, Th and Zn among molecular weight fractions of humic substances, the compost extract (extracted by 0.1 mol l(-1) sodium pyrophosphate) was analyzed by size exclusion chromatography coupled on-line with UV-Vis spectrophotometric and ICP-MS detection. Similar chromatograms were obtained for standard humic acid (Fluka) and for compost extract (254 nm, 400 nm) and three size fractions were operationally defined that corresponded to the apparent molecular weight ranges > 15 kDa, 1-15 kDa and < 1 kDa. The percentage of total element content in compost that was leached to the extract ranged from 30% up to 100% for different elements. The elution profiles of Co, Cr, Cu, Ni and Pb (ICP-MS) followed that of humic substances, while for other elements the bulk elution peak matched the retention time observed for the element in the absence of compost extract. Spiking experiments were carried out to confirm elements' binding and to estimate the affinity of individual elements for humic substances derived from compost. The results obtained indicated the following order of decreasing affinity: Cu > Ni > Co > Pb > Cd > (Cr, U, Th) >> (As, Mn, Mo, Zn). After standard addition, further binding of Cu, Ni and Co with the two molecular weight fractions of humic substances was observed, indicating that humic substances derived from compost were not saturated with these elements.

“…The occurrence, fate and distribution of elements in compost have been reported only in few studies. 3,4,32 Different sequential extraction schemes were used to assess the extractability of heavy metals at different stages of the composting process. 5,15 The effect of clay amendment on element binding in compost has also been investigated.…”

“…Rather surprisingly, little attention has been paid to the VOCs from compost heaps, and studies have focused on the production of gases such as CH 4 , CO 2 , NH 3 , N 2 O, and H 2 S. 22±24 The possible presence of metals in the compost has been acknowledged, 25,26 but VOMC emission has not been considered.…”

Landfill gas, cryotrapped on a loop fashioned from a length of a capillary gas chromatography (GC) column, was examined for volatile organometallic compounds (VOMCs) and for volatile organic compounds (VOCs) by using GC±mass spectrometry (MS). A large number of organic components were present and many were identified, but the only VOMCs present in high enough concentrations to be detected were trimethylstibine and tetramethyltin. The use of inductively coupled plasma (ICP)-MS as an element-specific detector allowed the identification of a number of other organometallic species in the landfill gas, including trimethylarsine and trimethylbismuth, and, for the first time, butyltrimethyltin and dibutyldimethyltin. The presence of molybdenum hexacarbonyl was confirmed. Gas from a large-scale compost heap and from compost incubated in the laboratory contained iodomethane but no common VOMCs (GC±ICP-MS). Only VOCs were present in forest air (GC±MS).

“…Estimation of environmental mobility of heavy metals using a sequential leaching of particulate material emitted from an opencast chrome mine complex leaching procedures has been used in many environmental studies for the determination of metals in a range of sample types such as contaminated soils near an old copper smelter [11], mercury-mining area [12], sediments [13], coal ash disposal [14], municipal [15] and mine waste waters [16].…”

A four-stage sequential leaching procedure was applied to assess the bioavailability and environmental mobility of heavy metals (Cr, Fe, Cu, Ni and Cd) in total suspended particulate (TSP) material emitted from an opencast chrome mine complex (Kemi, Northern Finland). TSP material was collected on glass fibre filters by a high-volume sampler, and a sequential leaching procedure was used to determine the distribution of heavy metals between the water-soluble fraction (H2O), environmentally mobile fraction (CH3COONH4), the fraction bound to carbonate and oxides (HONH3Cl + CH3COOH), and the fraction bound to silicates and organic matter, that is the environmentally immobile fraction (HNO3 + HF + HCl). The sequential leaching procedure was also applied to the certified reference materials VKI (QC Loam Soil A) and PACS-2 (Marine Sediment) to evaluate the accuracy and reproducibility of the leaching procedure. The heavy metals were determined by graphite furnace atomic absorption spectrometry (GFAAS) and flame atomic absorption spectrometry (FAAS). The concentrations of metals in the water-soluble fraction (H2O) decreased in the order Fe >Cu >Cr >Ni >Cd, and in the environmentally mobile fraction (CH3COONH4) in the order Cu >Fe >Ni >Cr >Cd.
