摘要：Childhood exposure to environmental heavy metals continues to be a major health concern. This study examined heavy metal content within the plastic childrens toys purchased from local markets of different districts of Uttar Pradesh, India. The six different colours of toys; yellow six brands, orange five brands, green three brands, red and blue four brands, grey and purple five brands and pink and purple three brands used in present study for the determination of concentrations of heavy metals as per BIS, IP and other international guidelines by using atomic absorption spectrophotometer (AAS). The results showed that the presence of metals were in the range of 0.219-1.12, 0.005-0.110, 0.251-1.090, 0.119-1.111, 0.219-1.040, 0.000-0.531 and 0.990-1.070 (ppm) for Pb, Cd, Ni, Zn, Cr, Co and Mn respectively. A comparison of the mean concentrations of these metals in the toys analysed showed the pattern as: Pb > Zn > Ni > Mn > Cr > Co > Cd.
