A National Academy of Sciences NASS) panel has issued a final report on the health implications of perchlorate ingestion, recommending a reference dose of 0.0007 milligrams per kilogram (mg/kg) body weight.
The relative bioavailability of folate following meal A exceeded significantly the suggested value of 50% for food folates by taking the dose-normalized area under the curve (AUC) following ingestion of meal B as reference.
Potential non-carcinogenic risks due to exposure of heavy metals were determined by comparing the calculated contaminant exposures from each exposure route (ingestion and dermal) with the reference dose (RfD) [31] using Eq. 3 in order to develop hazard quotient (HQ) toxicity potential of an average daily intake to reference dose for an individual via the two pathways using Eq. 4.
A reference to Litveneko's ingestion of Polonium at a sushi bar.
In the United States, the current U.S. Environmental Protection Agency EPAA) maximum acceptable "reference" dose for chronic BPA ingestion is 50 μg/kg /day, calculated as 0.1% of the lowest observed adverse effect level (LOAEL) determined from toxicity studies (U.S. EPA 1993).
We calculated the HQ as the ratio of the child's potential daily toxicant intake at home via non-dietary ingestion (mg/kg/day) to the specific toxicant chronic reference dose, RfD, (mg/kg/day).
The most notable references were to the oral ingestion of laxative mixture, perceived as directly intrusive as the actual endoscopic procedure.

Serum/plasma concentrations of ethylene glycol, propylene glycol, methanol, isopropanol, and acetone were measured by GC (Agilent 6850 with 7683 injector, Agilent Technologies, Santa Clara, CA, USA), which served as the gold standard (reference) technique for diagnosis of toxic alcohol ingestion.
The median gastric antral cross-sectional areas were significantly larger after ingestion of the meal including vinegar than after the reference meal at 90 min. This difference could be due to delayed gastric emptying and therefore increased amount of gastric juices and saliva in the stomach.
