Table 4

Calculated tolerable intake of heavy metals.

	TWI,; (g/kg b.w.)	TWI (70); (mg/person)	MaxWI (47); (mg/person)	MaxWI (84.9); (mg/person)
Cd	2.5	0.175	0.059	0.106
Pb	25.0	1.750	0.208	0.376
Ni		1.372	0.532	0.962

Notes: TWI: tolerable weekly intake [52, 53]; TDI: tolerable daily intake [54]; b.w.: body weight; MaxWI: maximum weekly intake, calculated according to the highest value of Cd (Pb, Ni) content determined in potatoes in regard to consumption 47 (84.9) kg potatoes per year:   (),   (),   (), (70, in kg) – default body weight used as default for the European adult population (aged above 18 years) [55]; (47, in kg/person/year): average consumption of potatoes [51]; (84.9, in kg/person/year): maximum in available interval of rational consumption of potatoes [51].
