Determination of Lead Contamination of Guava Fruits collected from Khartoum State

Abstract

The aim of the present study is to estimate and evaluate lead concentrations in guava fruit (Psidium guajava L.) in Khartoum State. Fruit samples were collected in June 2017 from (Khartoum, Khartoum North and Omdurman)covering the central markets and near traffic main stations and from 2 fruit orchards (Alkadaro and Algreif West)Eight samples with three replicates were digested and analyzed using atomic absorption spectrophotometer. The results showed that lead in guava fruits in all tested areas, was significantly (p<0.05) higher than the permissible limits set by FAO /WHO (0.3mg/kg).The mean values 0fPb content ranged between 0.76-1.9533 mykg. The difference in mean values between studied areas was not significant. Lead concentrations in Omdurman central market and near traffic station were lower than the concentrations of lead in samples from other studied areas.
