Likewise, all total PBDE concentrations of the individual samples exceed the totals from both 1987 and 1994/95.
When necessary, the number of generations was increased so that the number of discarded samples would not exceed 25% of the total sampled trees.
Of the 11,036 samples, 203 duplicate measures of personal samples were excluded because the number of personal silica samples exceeded the total number of workers who were sampled.
Three of the total samples exceed the permissible limit (300 mg/l) in our study area.
Seven and 19% of the total samples exceeded the WHO guideline for Fe and Mn, respectively.

The WHO guideline value is set at 0.4 mg/l and 19% of the total samples exceeded the WHO guideline.
Cl− levels in the samples ranged from 3.0 to 903 mg/l of which 1% of the total samples exceeded the taste guideline.
Pesticide residues were detected in 50% of the 16 samples, and approximately 19% of the total samples exceeded the MRL level provided by the World Health Organisation (WHO) or Food and Agricultural Organisation (FAO).
A particular multilocus genotype can be declared to be high-risk if the ratio of number of cases to controls exceeds the proportion of cases in the total sample.
