Risk of human exposure to arsenic and other toxic elements from geophagy: trace element analysis of baked clay using inductively coupled plasma mass spectrometry

Table 4 Percentage of permitted maximum tolerable daily intake (PMTDI) for different elements (median values were used) associated with consumption of sikor.

Element	PMTDI (μg kg^-1-bw day^-1)^a	PMTDI (μg day^-1)^a	Percentage of PMTDI from 50 g of sikor
As	2.1	126	293
Cd	1.0	60	28.3
Mn	200	12000	13.4
Pb	3.5	210	588

^a The numerical values shown are the tolerable daily intake for a 60 kg person derived from PMTDIs recommended by the Joint FAO/WHO Expert Committee on Food Additives (JECFA)¹⁴
