Hi Everyone!

Is there a way to calculate safe harbor limits of a chemical that is listed on the prop 65 list but does not have a NSRL or MADL limit?

Also is there a way to convert µg/serving to µg/day? How can we estimate how much of any given product the customer is going to consume in one day?

There is a ton of research available on peoples eating habits, I would start by just googling

"how much XXX do people consume in a month/day/year" and use that as your guide

which chemical specifically?

Because we always have is never an appropriate response!

I expect you can make a good case if you sell a breakfast food that one serving a day is the expected intake.

If it is a snack, then take the largest nutrient that would exceed RDI if double or tripled, 4x etc.; at which point you could say the calories or fat will get them before the metal????

A little tongue in cheek but it might help.
