Abstract
Milk is a complete liquid food source since it contains rich amount of protein, fat and major minerals. Presence of trace amount of toxic metals in milk products by any means make it unfit for human consumption. The aim of this study was to evaluate metals in raw milk of buffalos and cows from different farms of district Quetta. Fifty-six whole raw milk samples from cows and buffalos were collected and analyzed using atomic absorption spectroscopy for metal contents. Levels of metals (mean±SD) such as mercury (1.97±0.49 ppm), antimony (0.37±0.08 ppm) and aluminum (0.49±0.33 ppm) exceeded the maximum permissible concentration whereas, all other studied metals including arsenic, lead, iron, sodium, cobalt and chromium were below the recommended standard values of
期刊介绍：
Pakistan Journal of Zoology (Pakistan J. Zool.) publishes original articles in English on all aspects of animal life. Generally these articles will be in, or related to one of the following subject areas: Physiology, Cell Biology, Molecular Biology, Genetics, Bioinformatics, Toxicology, Forensic Science, Developmental Biology, Entomology, Parasitology, Microbiology, Biotechnology, Pathology, Palaeontology. Taxonomy, Environmental Biology, Wildlife, Fisheries, Vertebrate and Invertebrate Morphology. Additionally, the journal considers research on health and clinical studies. Short communications are regularly considered, however, uninvited review articles, first records/reports of known species, case reports/studies and survey reports are not published in Pakistan Journal of Zoology.
