    Author(s): Hira Yaseen*, S. Bashir, H. Z. Batool, S. Shaheenb and A. Hayat

    Toys of different brands were analyzed by Laser Induced Breakdown Spectroscopy (LIBS) technique employed for the analysis of toxic and nontoxic elements. All samples were irradiated without sample preparation treated under the ambient environment of argon gas. The analysis of emitted spectra reveals the presence of different elements in the samples which was verified by the National Institute of Standard and Technology (NIST) database. Both toxic and non-toxic elements like lead, tin, mercury, potassium and magnesium are found indifferent concentrations. The concentration of heavy metals like lead, mercury and tin in different toys were in the range of 897.2 ppm-320.5 ppm, 88.2 ppm-140.4 ppm and 8.4 ppm-10.2 ppm respectively which is much higher than the permissible value set by US Environmental Protection Agency (US EPA), US Food and Drug Administration (US FDA) and other regulatory ..
