Heavy metals (Pb, Cd and Zn) levels in roadside soils in

Nairobi County

Urban areas pollution is one of the environmental

institutions concern since there is increase in the

population of people in the urban towns. Pollution

in Nairobi town is mainly from man induced

activities including municipal waste, sewage

sludge, road traffics gas exhausts, atmospheric

deposits and agrochemicals such as fertilizers and

pesticides.

Atmospheric emissions tend to be of great concern,

because of the quantity, wide spread dispersion,

potential and their impacts on both biotic and abiotic

environment. The chemical analysis and accurate

determinations of concentrations of harmful and

toxic

elements is important for the development of

environmental risk assessment and monitoring.

Soil samples will be collected on road sides of

A104 and A109, then analyzed and results shared

upon completion of the project

Key words: Environmental pollution,
