“…Heavy metals present a risk for primary and secondary consumers and ultimately humans [5].Though some metals, e.g., Mn, Cu, Zn, Mo, and Ni are essential or beneficial micronutrients for microorganisms, plants, and animals, at high concentrations all metals have strong toxic effects and are environmental treat. Previous studies have showed that Hg, Zn, Cd, Co, Pb, Cu, As, Al, Cr, and Ni reduce the germination of many kinds of seeds [6][7][8][9][10][11][12].…”

The ecotoxicological effects of Zn2+ on germination and early seedling growth of six pulses were investigated. Seeds of these plants were exposed to seven different concentrations of Zn (0, 0.2, 0.4, 0.8, 1.6, 3.2, and 6.4 mM). The results indicated that root growth and shoot elongation of six pulse plants were more sensitive than seed germination and dry weight for measurement of the toxic of Zn2+ pollutions. Different species show different levels of tolerance to Zn2+ pollution. Vigna radiate and Lathyrus odoratus are the most sensitive to Zn2+, their germination percentage, root growth, shoot elongation and dry weight were significantly lower than other tested species, by contrast, Glycine max and Dumasia villosa are the most resist species, their germination and seedling growth almost were not influenced by Zn2+ pollution significantly comparing the control. There were significantly negatively correlations between seedling growth and increasing concentration of Zn2+ for Glycine max, Lathyrus odoratus and Dumasia villosa. The significantly negative correlations between germination and increasing concentration of Zn2+ were show for Lathyrus odoratus.

“…Bio-indicator are those plants which are more sensitive to pollutants and shows visible symptoms of contamination on the leaf and other plant systems, these plants are generally used as pollution marker, whereas bio-accumulator plants have built resistance against these pollutants; they can store pollutants without any visible damage on their morphology and physiology (Radnai, 1997). Burhan et al (2001) suggested that there are about 50 metals which are of special interest with respect to the toxicological importance to human health, plants and animals. Essential elements such as Fe, Zn and Cu are useful to plants at low concentration but playing a detrimental role in plant development at higher levels.…”

This study was conducted to determine the degree of heavy metal contaminations in the soils around the perimeter of an industrial park located in the city of Sta. Rosa, Laguna, Philippines that houses light-tomedium scale manufacturing industries, through accumulation of heavy metals in two plant systems viz. Bougainvillea spectabilis (bougainvillea) and Leucaena lecocephala (ipil-ipil). Results of study revealed that the soil samples collected from the study site contained higher concentrations of Cu and Zn compared to a residential site as non-polluted source, some amount of nonessential mineral like Cd and Pb was also found from the sample collected from the study area. Findings of the study suggested that Cu is an immobile element, was highly accumulated in the roots of B. spectabilis, while highest concentration of Zn was accumulated in the leaves. Moreover, the leaves of L. leucocephala collected from the study site accumulated significantly higher concentrations of both Cu and Zn as compared to the leaves of the same plant species collected in a residential site. The non-essential metals, Cd and Pb, exhibit no significant difference in their accumulation and distribution to different plant parts and between the industrial and residential sites.
