Abstract
The paper reports on the results of a survey of trace elements in common potatoes, sweet potatoes, cassava, yam and taro. The levels of aluminum, chromium, manganese, nickel, cobalt, molybdenum and cadmium in common potatoes, sweet potatoes, cassava, yam and taro consumed in Mato Grosso do Sul state, Brazil were evaluated. The concentrations were measured using a Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES, iCap 6000- Thermo Scientific, USA). It was shown that the levels of biometals in tu bers, with the exception of aluminum and chromium, vary in a broad range, but do not exceed the limits established by the Brazilian and International legislation when available. No major concerns were identified for the health of consumers. The concentrations of aluminum in all tubers (1.53 - 2.9 mg/kg) and chromium in taro (0.41 mg/kg) are higher, possibly reflecting the local soil characteristics or contamination and needing geochemical information.
