Urban Farm DB summary
A study in Nairobi's eastern zone assessed heavy metal occurrence in urban farm inputs and food crops (tomatoes, arrowroots, kales). Cadmium, manganese, lead, and zinc concentrations were analyzed in soil, water, and crop samples. The study found that heavy metal contents, particularly cadmium, manganese, lead, and zinc, were above allowable limits in several crops, and based on FAO/WHO standards, were high for health concern.
