The intake of leafy vegetables in daily diet is very important to meet our nutritional needs. Vegetables provide the essential
elements which are necessary and recommended for human growth. However, due to rapid industrialization and urbanization our
environment becomes polluted and this affects the normal growth of agricultural products and composition of environmental
species. The elemental concentrations present in the environmental samples are good indicators to assess the toxicological
levels due to pollution affects. In the present work we have analysed several vegetable plant samples by instrumental neutron
activation analysis to determine the elemental concentrations at major, minor and trace levels. The leafy vegetables like
spinach, red leafy veagetable, pui, gourd leaf, lettuce and katoua were chosen as these are extensively consumed by local
peple in eastern part of India. We have determined 15 elements in the above mentioned vegetable samples and some of these
are essential elements and some are toxic elements. It was found that Na and K were present as major elements, Fe and Zn as
minor elements and As, Ce, Cr, Co, La, Mo, Rb, Sc, Sm, Sr as trace elements. The concentration level of Cr was found to be
higher than that of recommended value certified by WHO and National environment quality control for human consumption. The
validation of our analytical results have been performed by the Z-score tests through the determination of concentrations of the elements of interest in certified reference materials.
Variations in concentration of elements with different washing methods of hair-EDTA Method and Acetone Method-and different lead work employees (lead processing workers and lead glass-making workers) were studied by nondestructive neutron activation analysis. The EDTA Method removed not only the external, elements bound by surface adhesion but also the internal elements, such as Mg and Ca, existing in hair. With the Acetone Method, Zn, As and Sb concentrations in hair of lead processing workers show very high values (>2) and Cd and Co concentrations in hair of both groups show high values (1<<2), except for Pb. This suggests the effect of environmental pollution in that factory.
k0-Based instrumental neutron activation analysis (k0 INAA) was used to determine the concentrations of Cr, Fe, Co, Zn, Se, Sb and Hg in the vascular plantsCistus salvifolius andInula viscosa and in the lichenParmelia sulcata. The samples were collected in the neighbourhood of industrial complexes. The elemental accumulation in the vascular plants and the lichen are compared to optimize the choice of the bioaccumulator. It is concluded thatP. sulcata seems to be the best accumulator of the three species for the elements studied;Cistus salvifolius is sensitive to the contents of Zn, Fe, Cr and Sb in the air;Inula viscosa seems to accumulate Fe, Sb, Co, Cr and Zn. Nevertheless, it is concluded that lichen is a good air pollution indicator, while the vascular plants are not due to the large seasonal variations found in the elemental concentrations.
