Table 4: Chronic exposure
Chronic exposure to sum of T-2 and HT-2 from processed barley, oats combined (combination of processed oat grains and unprocessed oat grains with reduction factor) (RPC) and processed wheat based on DNSYIC and NDNS years 1-11 consumption data and occurrence data collected from the FSA call for evidence (µg/kg bw/day; LB-UB).

*Estimates have been rounded to 2 significant figures.
++ Oats combined - combination of processed oat grains and unprocessed oat grains with reduction factor (identical to “Oats combined” from Table 4 above).
LB - Lower bound: values below the limit of quantification (LOQ) are treated as zero; UB - Upper bound: values below the LOQ are treated as at the LOQ.
