Abstract:
The potential risk that heavy metals cause during the early stages of childhood
development makes it a global health concern. Main aim of this study is to determine
the concentration of cadmium, chromium, nickel copper, and chromium (VI) to carry
out dose response assessment, evaluating questionnaire responses given by children’s
parents in Lahore, Pakistan and calculating hazard quotient (HQ) in order to evaluate
whether concentrations are above or below permissible limit.
