Title : Health risk assessment for peri-urban grown food crops in Kibra slum Kenya

Abstract:

Peri-urban farming in Kibra slum, Nairobi is observed to use contaminated water or growing food crops alongside contaminated water sources. The alarming levels above the European Union limits for elements in kales, amaranthus, arrowroots and spinach from the area have been reported as a concern to human health. The daily intake of metals (DIM), Target hazard quotient (THQ) and incremental lifetime cancer risk (ILCR) were employed as indices for health risk assessment for selected essential (Mn, Mg, Cu, Fe, Zn and Al) and non-essential(Cr and Pb) elements of food crops grown in Kibra slum. A randomized block design was used to obtain samples of arrowroots, amaranthus, kales and spinach from six farms. Analysis of the elements was done using AAS. While only Cr and Pb in the foods were above the EU limits, the DIM of Fe and Mn and THQ for Mn and Fe implied health risk according to FAO/WHO. Consequently the ILCR index for Pb showed 0.043% of Kibra slum populations were likely to develop cancer in a lifetime.
