Daily human intakes

Farm animals are exposed to PCDD/F via the ingestion of contaminated forage, grains and soil. Owing to its high lipophilicity, dioxin readily bioaccumulates in cattle and has been detected in beef, milk and dairy products. Several studies point out that meat and dairy products account for up to 60% of the total daily human intake of PCDD/Fs in industrialized nations.39,46 PCDD/F levels in beef... 

An evaluation of the developmental effects of DEHP by the National Toxicology Program estimated that the no-observed-adverse-effect level (NOAEL) for DEHP in sensitive species to be 44 mg kg day more than 500 times the estimated daily human intake. A more recent estimate found a similar wide disparity between typical oral exposures to DEHP in humans and an NOAEL in rodents of 4-14 mg kg day ... 

Consequently, daily human intake of these compounds from inhalation and ingestion routes remains unknown. Although the intake of dinitrophenols by the general population is expected to be low, studies that evaluate the daily intake would be useful. Since vehicular exhaust contains dinitrophenols (Nojima et al. 1983), it would be helpful to analyze roadside soil to determine whether such soils contain elevated levels of dinitrophenols. 

Vanadium is ubiquitous, so it is not surprising that it is contained in the foods that humans consume. Older data are reported in the mg-range (Schroeder et al.. 1963) recent data show that it is likely that vanadium concentrations in common food do not exceed a few fig/kg (NAS, 1974). Data on meat are of the order of 1 fig/kg (Byrne and Kosta, 1978). Nevertheless, food is the main source of vanadium intake for man. The daily human intake of vanadium from food is in the order of few tens of micrograms (Byrne and Kosta, 1978). In other studies daily intakes of 8.2- 13.2/[Pg.528]

The average daily human intake of flavonoids varies from as low as 25 mg to as high as 1 g [76-80]. After oral ingestion, some of the ingested flavonoids are...
