Heavy metals have been widely reported in cassava mill effluents [6-10]. Typically, heavy metals are naturally occurring metals that have a high atomic weight and a density at least 5 times greater than that of water [11-14]. Heavy metals are typically classified into essen-

Extensive irrigation by the effluents released from a paper mill near Nanjangud have led to the accumulation of heavy metals in the soil and different parts of the paddy crops. In this paper, the physicochemical characteristics of paper mill effluents and the accumulation of heavy metals (Cu, Zn, Pb, Co, Cd, Cr, and Ni) in the soil and different parts (root, leaf, and seed) of the …

2005. A. Mill scale consists primarily of magnetite, Fe 3 O 4, of characteristic blue-gray "steely" color. An extremely thin outer film of hematite, Fe 2 O 3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO (see below), which contribute to the roughness of descaled metal.

Acidic waste streams, for example, olive mill waste, cause soil-borne heavy metals leaching. • Morphological characteristics of the disposal areas define contamination dispersion. • Metals' fate also depends on soil properties and disposal practices. • Local particularities should be considered for the estimation of risk indices.

Certain plants have the ability to accumulate heavy metals such as Pb, Cr, Cd and Zn. At present, phytoremediation of metals may be approaching commercialization. Hence, possibility can be explored to remove heavy metal load, present even in low concentration, in waste water of paper mill effluent soil by using Croton sparsiflorus.

Most heavy metals (HMs) were more concentrated in the L. esculentum roots than in any other tissue. Most HM levels in L. esculentum tissues correlate significantly with HM levels in soil. L. esculentum was documented by a bioconcentration factor > 1.0 for most HMs. The translocation of HMs by L. esculentum was below 1 for most examined HMs.
