potential of modified corn cob (zea mays l.) and petailead metal is one type of heavy metal that has high toxicity levels in the aquatic waste environment. the adsorption method is one of the alternatives in reducing heavy metal waste, by utilizing biosorbent. the purpose of this research is to study the process of making new biosorbent and to know the absorption of new biosorbent from corn cob (zea mays l.) and petai hull (parkia hassk) toheavy metal concentration of dumpsite soil andconcentration (53.283 ppm). large disparity was observed between cu (.4 ppm) and pb (.465 ppm) concentrations with zn. cd (0.6 ppm) has the least concentration of all the heavy metals in the dumpsite. however, despite the variations in concentration levels obtained for these metals, the data gathered were still withinzea mays l.) impacted by smelting emissions1 1 allocation and source attribution of lead and cadmium in maize 2 (zea mays l.) impacted by smelting emissions 3 xiangyang bi a, b, xinbin feng a, , yuangen yang a, xiangdong li c, grace p. y. shin 4 c, feili li d, guangle qiu a, guanghui li a, taoze liu a, and zhiyou fu a 5 6 a state key laboratory of environmental geochemistry, institute of geochemistry,remedial ability of maize (zeamays) on lead contaminationremedial ability of maize (zeamays) on lead contamination under potted condition and nonpotted field soil condition author chiwetalu, uche jenice, mbajiorgu, constantine crowner, ogbuagu, nneka juliana source journal of bioresources and bioproducts v.5 no.1 pp. 59 issn 23699698 subjectassessment of the levels of mycotoxins in varietiesan overall order of concentration in the cereals by aflatoxin b 1 was maize > millet > rice > wheat, while by ochratoxin a and fumonisin b 1+b 2 it was maize > rice > millet > wheat. results indicated that the levels of aflatoxin b 1, ochratoxin a, fumonisin b 1 + b 2 and zearalenone were within nigerian and european permissible limits ofheavy metals uptake in maize grains and leaves inthis study aimed at monitoring the levels of heavy metals uptake in maize (zea mays) grains and leaves is within permissible levels. level of heavy metals in maize grains from different ecological zones in ug county had mean concentration of zn 0.2, cd 0.03, cu 0.1, co 0.04, and pb 0.33 mg/kg.health risks assessment diagnosis of toxic chemicalsthe present study investigated the concentration of metals in commonly grown vegetables (luffa acutangula l., zea mays l., solanum melongena l.) irrigated with waste water in district bannu, khyber pakhtunkhwa, pakistan. the ph (5.80)assessment of heavy metal accumulation in wastewaterconcentration of heavy metals in soils, and has an effect on the subsequent accumulation in maize plants. tables are presented which show concentrations of the heavy metals in soils, plant and cob, for both site a and site b. for all the selected heavy metals, mean concentrations were significantly higher (p < 0.05) on site a,permissible concentration of lead for zea mays(the embryos of zea mays l.). maximum permissible concentration lead (pb) 0.1 mg/kg arsenic inquire now; determination of heavy metals in sugar industry . concentration of cd and cr were within the permissible limit of indian by corn (zea mays l for the determination of lead or cadmium concentration. inquire now
