Studying Heavy Metal Assessment of Some Soft Plastic Toys Imported into Sudan from China and Taiwan

Abstract

China and Taiwan made toys were analyzed to determine the levels of heavy metals (Pb, Cd, Hg, Ni, Cu, Zn, Cr, Co and Mn) in the products. Twenty one Toy samples were randomly selected from products available in the shops at Khartoum. The toy samples were tested for PVC before analysis. Concentrations of the selected heavy metals were determined ppm and 3sigma. Samples tested positive for PVC. Concentrations of heavy metals in the toys ranged from for Pb, Cd, Ni, Cu, Zn, Cr, Co and Mn respectively. Both PVC and non-PVC toys contain. Heavy metals but the concentration of these metals in non-PVC toys is generally less than that of PVC toys. The present study reveals that most samples in agreement with standard concentration except two elements vacillates of the toy samples show high concentration (above USFDA limit) of Hg, Cr and other metals determined; this poses a threat to children exposed to such toys.
