Effectiveness of lime and peat applications ... - SpringerLink

Jan 12, 2016 · Abstract. In paddy soils, amendments and moisture play important role in the immobilization of cadmium (Cd). The effects of applying lime, peat, and a combination of both on soil Eh, pH, and Cd availability in contaminated soils were investigated under wetted (80 ± 5 % of water holding capacity) and flooded (completely submerged) conditions.

Impact of Long-Term Diesel Contamination on Soil Microbial ...

When each soil matrix type (fill, peat, clay, and sand) was considered separately, only fill and peat samples showed a significant difference in microbial diversity between clean and contaminated samples (P < 0.05). The clay group was too small to assess the significance of observed differences in diversity.

Adsorption of Polycyclic Aromatic Hydrocarbons (PAH) on ...

In this project Sphagnum peat moss adsorption of polycyclic aromatic hydrocarbons (PAH) to peat, has been studied for the potential use as filter material for treatment of contaminated waters and remediation of contaminated soils. The adsorption of PAH to peat, and the adsorption of PAH to peat when cadmium is present was investigated.

Soil contamination - Wikipedia

Soil contamination or soil pollution as part of land degradation is caused by the presence of xenobiotics (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste.

Remediation of diesel-oil-contaminated soil using peat ...

The authors investigated a remediation process for diesel-contaminated soil, in which water was used to remove the diesel from the soil and peat was used to absorb the diesel layer formed on the surface of the water. The percolation of water through the soil was uniform. The time required for water ...

Peat soils as a source of lead contamination to upland ...

Contaminated peat soils of the catchment are a significant source of lead to the fluvial system. This study has demonstrated strong coupling between the physical process of erosion and the mobilization of lead into the fluvial system. The process of peat erosion should therefore be considered when estimating lead outputs from peatland ...

Determination of oil content of oil contaminated soil ...

The effectiveness of methylene chloride as an extractant to measure the oil content of oil-contaminated soils was examined. Soil preparation and pretreatment requirements were also studied. The results indicate that methylene chloride extracts topped crude oil efficiently from both mineral and organic soils.

Acid sulfate soil - Wikipedia

Acid sulfate soils are naturally occurring soils, sediments or organic substrates (e.g. peat) that are formed under waterlogged conditions.These soils contain iron sulfide minerals (predominantly as the mineral pyrite) or their oxidation products. In an undisturbed state below the water table, acid sulfate soils are benign. However, if the soils are drained, excavated or exposed to air by a ...

Soil Science Society of America Journal Abstract - Heavy ...

Heavy metal contamination of soils may reduce yields as well as the suitability for consumption of crop growth (Keeney et al., 1977; Leeper, 1978). In an effort to find possible ways to counter this danger, the effect of lime, chelating agents, and peat applied to Zn-, Cu-and Pb-contaminated soils on the uptake of metal ions were studied.

There have been contradictory viewpoints whether soil amendments immobilize or mobilize heavy metals. Therefore, this study evaluated the mobility and bioavailability of Pb, Cu, and Cd in contaminated soil (1218 mg Pb per kg, 63.2 mg Cu per kg, 2.8 mg Cd per kg) amended with peat moss (0.22, 0.43, and 1.29%

Effect of sawdust treatment at diesel oil contaminated soil

adsorbents such as muck, peat, sawdust and PEAT S, that is commercial products for adsorbing oil, were treated at diesel oil contaminated paddy soil. As the results, sawdust and PEAT S showed better effect for diesel oil removal from the contaminated soil than muck and peat. Removal rate of diesel oil was higher than 95% with sawdust treatment
