New cards

Dose

How much of a particular contaminant are you exposed to?

4
New cards

Duration

For how long are you exposed?

  • acute = < 14 days

  • Intermediate = anything in between (14-364 days)

  • Chronic = 1+ year

New cards

Half life

The amount of time it takes for half of the chemical to either be excreted or metabolized

  • short half-life = Body gets rid of it quickly

  • Long half-life = It stays in our system for a long time

Bioaccumulation

Is when the amount of a chemical increases in the living organism overtime
