“…Cd is a toxic and bioaccumulative metal characterized by a long half-life (Barbier et al, 2005; Kumar and Sharma, 2019), and Cd competes in the organism with other essential elements such as Zn, Fe or Cu causing serious damage to the renal system (Rubio et al, 2017b). Cd levels are high in plant products such as tofu and diet is the main Cd exposure for non-smoker population (Kosečková et al, 2020).…”

Potentially toxic elements (PTEs) (V, B, Ba, Li, Sr, Cr, Ni, Al, Pb, Cd) were determined in 130 samples of different tofu types (natural, avoured, smoked and fresh made) by ICP-OES (inductively coupled plasma optical emission spectrometry). Al was the most notable element found with the highest concentration (6.71 mg/kg ww) found in avoured tofu. Ni level (0.38 mg/kg) stands out in smoked tofu. European tofu has higher PTEs levels than Chinese tofu. Organic produced tofu has higher PTEs concentrations than conventional produced tofu. 200 g/day of smoked tofu confers a contribution percentage of 39.6% of its TDI (tolerable daily intake). In addition, 200 g/day of avoured tofu would mean a high Pb contribution with a 23.2% of the BMDL (benchmark dose level) set in 0.63 µg/kg bw/day to the development of nephrotoxicity. Mean consumption would not pose a risk to adults' health. Considering the obtained results, it would be advisable to establish limits for certain metals such as Pb, Al and Ni in this type of product. Furthermore, it is recommendable to set consumer guidelines to some tofu types in order to avoid excessive intake of PTEs.
