Percentages of samples of cooked gamebirds and chicken estimated from fitted lognormal models to have exceeded each of three threshold values of lead concentration (100, 1000 and 10000 ppb wet weight).

All samples are from the WWT study. Estimates with and without an adjustment to allow for within-bird variation in concentration among aliquots of meat are shown. The adjusted values approximate what would have been expected if the measurements of concentration in the whole meal derived from each bird had been available. The raw values are equivalent to the modelled values in Table 3, but data for acid and non-acid cooking methods have been pooled for each species.
