Heavy metal toxicity

Other papers in the Symposium deal with the antioxidant and hypolipidemic effects of IP6, its chelating effects in heavy metal toxicity, inhibition of renal stones and other beneficial effects such as inhibition of platelet aggregation, inhibition of inflammatory responses (Shamsuddin, 1998). The lipid lowering effect and anti-neoplastic effect of 1P6 were extensively reviewed (Jariwalla, 1999). Hence, 1P6 is a valuable component of rice bran in preventing disease and maintaining health. 1P6 is present at 1.8-2% in rice bran.

Heavy metals, toxic organics and other pollntants have often freqnently been added to wetlands both accidentally and on pnrpose, exploiting their buffering and storage capacities. The chemistry of snbmerged soils and sediments is such that pollutants may be effectively removed from the percolating water in redox, sorption and precipitation reactions. But the effects of long-term accumulation of pollutants on nutrient cycles and other wetland functions are not well understood.

The MetPAD test kit (Group 206 Technologies, Gainesville, Florida) has been developed for the detection of heavy metal toxicity. It has been used to determine the toxicity of sewage water and sludge, sediments, and soil [41]. The test is based on the inhibition of (3-galactosidase activity in an Escherichia coli mutant strain. Performance of the test does not require expensive equipment and it is therefore easily applied as a field test.

Inorganic cations, although probably isolated by ion exchange, should not be soluble in the dichloromethane extract of the aqueous eluents and should probably remain therein. The experiment with lead(II) nitrate, which yielded <0.2 of the spiked Pb ion, supported this expectation. Therefore, heavy metal toxicity to bioassay systems should not be a problem for testing organic residues. Conversely, when inclusion of inorganics in a test residue is desirable, other recovery techniques should be considered.

Heavy metal toxicity in plants is infrequent (143). In many cases, metal concentrations in plant parts show poor correlation with soil concentrations of the element (147). Plants tend to exclude certain elements and readily accept or concentrate others. Lisk (148) reported natural plant soil concentration ratios of 0.05 or less for As, Be, Cr, Ga, Hg, Ni, and V. Cadmium appears to be actively concentrated and selenium appears to be easily exchangeable. Indicator plants are capable of markedly concentrating specific elements, e.g., Astragalus spp. for selenium (138) and Hybanthus floribundus for nickel (149). Plants growing on mine wastes have been shown to evolve populations which exhibit metal-specific tolerances (150).
