A laboratory incubation experiment was conducted to study the influence of cadmium (Cd), lead (Pb)and zinc (Zn) on the size of the microbial biomass in red soil. All the three metals were applied, separately,at five different levels that were: Cd at 5, 15, 30, 60 and 100 μg g-1; Pb at 100, 200, 300, 450 and 600 μg g-1 and Zn at 50, 100, 150, 200 and 250 μg g-1 soil.

Since 2015, reasonably increasing the application of straw has been encouraged to increase organic matter in agricultural soils and reduce the application amounts of chemical fertilizer.

The molecular and petrographic characteristics of organic matter in internal sediments from the Mississippi Valley-type lead-zinc deposits in southern Poland reveal immature and well-preserved organic matter. Huminite reflectance values of organic matter in all internal sediments are low, with a mean value of 0.29%, corresponding to a lignite ...

lead, zinc, or both is fed, in some cases after sin-tering, into a primary smelter. Lead concentra-tions can be 50–70%, and the sulfur content of sulfidic ores is in the range of 15–20%. Zinc con-centration is in the range of 40–60%, with sulfur content in sulfidic ores in the range of 26–34%. Ores with a mixture of lead and zinc ...

A dull, silvery-grey metal. It is soft and easily worked into sheets. This easily worked and corrosion-resistant metal has been used for pipes, pewter and paint since Roman times. It has also been used in lead glazes for pottery and, in this century, insecticides, hair dyes and as an anti-knocking additive for petrol.

Sewage sludge (SS) or sewage sludge compost (SSC) were applied to soil under controlled conditions, at rates of 0 or 200 Mg ha−1, to investigate changes in dissolved organic matter (DOM), humic acids (HA), and Pb and Zn sorption in the soil. Infrared spectroscopy, visible spectrophotometry, and sorption isotherms (mono-metal and competitive sorption …

In order to understand the size distribution and the main kind of heavy metals in particulate matter on the lead and zinc smelting affected area, particulate matter (PM) and the source samples were collected in Zhuzhou, Hunan Province from December 2011 to January 2012 and the results were discussed and interpreted.

A shortage of zinc in the diet can lead to delayed healing, skin irritation and loss of the sense of taste, and encourages many chronic illnesses. With zinc also appearing in anti-dandruff shampoos in the form of zinc pyrithione and in underarm deodorants as zinc chloride, this is an element that even makes us more attractive to the opposite ...

Only a small amount of new lead is required to compensate for the losses during its use. Within EU, the total consumption of lead for Zinc production is about 6,000 tonnes/year. Lead anodes are essential to create zinc. Zinc is essential to protect steel against corrosion, which is key element for solar panels and wind turbines.

Therefore, at present, a common phenomenon is that many lead-zinc deposits in the world are closely paragenetic or spatially associated with oil and gas reservoirs (Kesler et al., 1994;Lin, 1995 ...

The practice represents a soil, sand, organic matter, and vegetation-based storage and infiltration facility used in parking lots and on individual lots to treat runoff. ... bioretention systems and two existing bioretention facilities documented their effectiveness at removing low levels of lead, copper, and zinc from synthetic stormwater ...

K 2 HPO 4-modified biochar (PBC) was produced and used in a 90-days immobilization experiment with soil collected from a typic lead-zinc (Pb–Zn) mining soil. Incubation experiments showed that PBC enhanced the transformation of Cd, Pb, Zn and Cu from exchangeable (Ex-) and/or carbonate-bound forms (Car-) to organic matter …

At present, the pollution of arsenic (As) and lead (Pb) is becoming increasingly serious. The pollution caused by the release of As and Pb from lead–zinc mines has seriously affected the water and soil environment and threatened human health. It is necessary to reveal the release characteristics of As and Pb. The actual scene of …

The results obtained in the determination of Ba, Cd, Cr, Mn, Pb and Zn in samples of atmospheric particulate matter by ICP-AES method agree well with the corresponding values obtained by both FAAS and dc arc-AES methods (Table 8).
