الملخص EN

This research is a first attempt to examine some heavy metals in plastic toys available in some of Aden Governorate markets-Yemen and to evaluate the toxicity effects on kids’ health.

To achieve this goal, we examined ten plastic toys as samples randomly.

These toys were purchased from toy shops and stalls in Aden Governorate.

The toys were assembled and classified by type, colour, and playing method: by mouth only, by hand only, or by both (which are the typical playing methods by children between 1-6 years old).

The samples were prepared then analyzed at the National Research Center-Egypt.

Toxicity Characteristic Leaching Procedure (TCLP) was used for the samples and then followed by the ICP-OES technique to determine heavy metals concentration namely: arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), Iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn).

Using TCLP in this study showed that all heavy metals levels were less than previous studies and if available, they are within the local and international acceptable levels.
