6. Errors in data
Similar misrepresentation of the reported data was present in the biosolid derived and manure derived sections. Dry weight concentrations are always higher than the fresh weight hence the PPCP intake to exceed ADI T-5224 considerably underestimated. Furthermore, the data do not always accurately reflect the worst case scenario. The difference between values of concentration and index calculated for dry and fresh plant weight can dramatically change the worst case scenario for different crops with varied PPCP concentrations and water content.
The “adult intake to exceed ADI (g/day)” was estimated using concentrations calculated for dry weight rather than fresh weight. The ADI should present fresh weight values because people buy and consume fresh vegetables and fruits. The “ADI” values (Table 1; Prosser and Sibley, 2015) are incorrect and should be calculated for the fresh weight of plants.
The relevance of the estimated daily intake (EDI) values is also questionable. This index should be calculated based on consumption data available for adults and toddlers separately. The use of the value 2.8 cups per day ignores different consumption habits by adults (2.9 cups/day) versus toddlers (1.45 cup/day) ( National Cancer Institute, 2005). The EDI was calculated assuming that all people consume 2.8 cups of a single vegetable per day, which does not represent a realistic scenario. Furthermore, the value presented in arrector pili review acquired from the U.S. based National Cancer Institute is only valid for the United States whereas different countries have different dietary consumption habits of fruits and vegetables. Generally, the relevance of the data, discussion and conclusions of this review are highly questionable.
