Comparative Analysis of Heavy Metals from Groundwater Sources Situated in Keko and Kigogo Residential Areas, Dar es Salaam

Urban Farm DB summary

This study assessed heavy metal concentrations in 12 groundwater samples from Keko and Kigogo areas in Dar es Salaam, Tanzania, during dry and rainy seasons. While copper and zinc concentrations were low, lead concentrations were detected beyond WHO permissible levels (0.01-0.35mg/l). This high lead presence may be attributed to urban agriculture activities, onsite facilities, and industrial waste discharge around the Msimbazi river.
