Lead, Nickel and Cadmium in the coating of children’s toys effects and influencing factors

Abstract

The paint covering the toy contains a high percentage of heavy metal, which is a cumulatively toxic source despite the limitations set by organizations such as WHO standard. This study is concerned about measuring the amount of Lead, Cadmium, and Nickel in the children’s toys. Thirty-two samples of plastic toys were collected, in different colors i.e. black, red, and yellow that are used for all age groups 3-12 months, 1-3 years and finally 3-6 years. The samples were analyzed using SPSS program. From the results it was found that the concentration of Lead between (8.0625-12.1875 mg / kg), Nickel (7.125-12.8125 mg / kg), and Cadmium, (2.96875-4.0625 mg / kg), provided that all results were lower from that recommended by the standard of (ISO-8124-3) and US EPA. The black color toys have high concentration of heavy metal, from the SPSS program analysis show high correlation between concentration of heavy metal with different parameter, except the correlation between lead with prices and Nickel with color.
