Samples of two crop seeds (c and sesame) grown ondifferent contaminated soil sources, were collected and preparedfor neutron activation analysis. Soil contamination sources wereorganic waste compost applied to soil amendments namely, sewagesludge(Bs) and municipal solid waste (MSW) at different 4%, 6% and8%. The non destructive NAA technique was used to determine sometrace elements accumulation in plant seeds.Results revealed that increasing rate of tested organic wasteresulted in dramatic increase in tested heavy metals levels inseeds(i.e., Fe, Zn, Co, Cr, Sc and Hg). Sesame seeds showed higheraffinity to accumulate trace elements than c grains in mosttested elements. Moreover, MSW addition enhanced the accumulationof tested metals in seeds more than Bs compost.
