Assessment of Heavy Metals in NPK-Treated and Untreated Sugarcane Juice Cultivated in Papalanto, Ogun State, Nigeria

Abstract

There is a lot of public health concern about food contaminated with heavy metals. Most of human exposure to harmful heavy metals is via intake of contaminated food.In this research work, the NPK-treated (fertilizers added) and untreated (no fertilizers added) sugarcane samples were collected from major farms in Papalanto, Ogun State, Nigeria. The result clearly shows that both samples contain some heavy metals such as lead, copper and cobalt. The levels of lead and copper were higher in the NPK-treated sugar cane while cobalt level was higher in the untreated sugar cane.
