  • Title: Non-carcinogenic health risk assessment and source apportionment of selected metals in source freshwater Khanpur Lake, Pakistan.
    Author: Iqbal J, Tirmizi SA, Shah MH.
    Journal: Bull Environ Contam Toxicol; 2012 Feb; 88(2):177-81. PubMed ID: 22120698.
    Abstract:
    Selected metals (calcium, cadmium, cobalt, chromium, copper, iron, potassium, lithium, magnesium, manganese, sodium, lead, strontium and zinc) were measured in water samples from a source freshwater Lake. Average levels of cadmium, cobalt, chromium and lead in the waters were significantly higher than the guideline values. Health risk assessment was then carried out to determine health risk via oral route and dermal contact. Hazard quotient (via ingestion) levels of cadmium, cobalt, chromium and lead were higher than unity; suggesting potential adverse effects on local residents. Principal component analysis revealed considerable anthropogenic contributions of the metals in the water reservoir.
