Different Growth and Physiological Responses to Cadmium of ...

Miscanthus has been proposed as a promising crop for phytoremediation due to its high biomass yield and remarkable adaptability to different environments. However, little is known about the resistance of Miscanthus spp. to cadmium (Cd). To determine any differences in resistance of Miscanthus to Cd, we examined plant growth, net photosynthetic rate (Pn), activities of anti-oxidant and C4 ...

Cadmium in China - WHO

Since the ore dressing plants began operations in 1960, it can reasonably be assumed that cadmium pollution started from that time in Dayu County since the wastewater from the plants is a major source of the element; a lower level of pollution may, however, have been present even before 1960.

A 4-year field experiment was conducted to study the transfer of Cd, Pb, and Zn from soil contaminated by smelter flue-dust to crop plants grown in a rotation. The soil was amended with Pb Zn smelter flue-dust (2–66.8 kg per 10 m 2 plot) to simulate the long-term effect that the smelting of non-ferrous metal ore has on arable soils. The ...

Cadmium - Wikipedia

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific ...

Cadmium in Soils and Plants | SpringerLink

Abstract. Cadmium can be a potential threat to a wide range of biota because (i) it is non-essential and non-metabolic, (ii) it is toxic to humans at concentrations lower than those toxic to plants, (iii) it is more mobile and bioavailable than other metals, and (iv) its effects on humans are cumulative.
