Acceptable daily intake or ADI is a measure of the amount of a specific substance (originally applied for a food additive, later also for a residue of a veterinary drug or pesticide) in food or drinking water that can be ingested (orally) daily over a lifetime without an appreciable health risk. [1]
Estimating or calculating the dietary exposure to a given chemical or contaminant allows a comparison to a relevant health standard such as the acceptable daily intake(ADI), the acute reference dose (ARfD) or a reference dose (RfD), or a level known to cause adverse effects in animal or human health studies. [2]
Tolerable daily intake (TDI) refers to the daily amount of a chemical contaminant that has been assessed safe for human being exposure on long-term basis (usually whole lifetime). [1] TDI specifically occurs to chemicals that humans are exposed to unintentionally or as a contaminant, [ 1 ] where acceptable daily intake refers to chemicals that ...
The EPA then looked at dietary exposure to endosulfan, and found that for the most exposed 0.1 % of children age 1–6, their daily consumption of the endosulfan exceeded this RfD. To remedy this, the EPA revoked the use of endosulfan on the crops that contributed the most to exposure of children: certain beans, peas, spinach, and grapes. [3]
The exposure assessment is initiated by selecting the appropriate exposure limit averaging time and "decision statistic" for the agent. Typically the statistic for deciding acceptable exposure is chosen to be the majority (90%, 95% or 99%) of all exposures to be below the selected occupational exposure limit.
An occupational exposure limit is an upper limit on the acceptable concentration of a hazardous substance in workplace air for a particular material or class of materials. It is typically set by competent national authorities and enforced by legislation to protect occupational safety and health.
Their daily limits range from 10-48 g per day for both men women, and weekly limits range from 27-196 g/week for men and 27-140 g/week for women. The weekly limits are lower than the daily limits, meaning intake on a particular day may be higher than one-seventh of the weekly amount, but consumption on other days of the week should be lower.
The European Food Safety Authority (EFSA) reviewed the safety of caramel colorings in 2011 and revised the previously established Acceptable Daily Intakes for these products for reasons unrelated to 4-MeI exposure. The Administration's review concluded that there is no evidence to show that caramel colors have any adverse effect on human ...
