-
24 samples of different brands of yoghurt were collected from 2 popular Lagos market and Atomic Absorption Spectrophotometer was used for the determination of heavy metals i.e. Lead, Cadmium and Chromium. 100% of the samples were found to have the concentration of heavy metals below the safe limit recommended by world health Organization (WHO). The concentration of Lead, Cadmium and Chromium fall between 0.52ppm – 0.92ppm, 0.14ppm – 0.49ppm and 0.26ppm – 0.75ppm respectively. The group mean of concentration of each elements (Lead, Cadmium and Chromium) in all brands are 0.70ppm, 0.27ppm and 0.41ppm respectively. This findings suggest that the concentration of all the heavy metals in yoghurt falls within the safe limits. The recommended Lead (pb), Cadmium and Chromium are 0.2 – 2.0ppm, 0.5ppm and 1.0ppm respectively according to World Health Organisation, but the relatively increase of Lead (pb) in yoghurt could be attributed to the industrialized status of Lagos State which if not checked might lead to greater value eventually.

CHAPTER ONE - [ Total Page(s): 2 ]The presence
of the most undesirable elements in foods can usually be attributed to
any of the following causes:· Natural occurrence e.g. deposition in the liver of animals.· Sprays used as insecticides during cultivation e.g. Lead arsenate.· Accidental contamination due to confusion of materials of similar appearance.·
Food may dissolve metals from the equipment and containers e.g. from
Tin plate, foils, solders galvani ... Continue reading---
