Here's how it works.

Five screenshots from the live calculator, walking through the flow you'll see when you launch it.

Select options that reflect your daily diet, and we will calculate the total lead intake you are receiving in micrograms of lead per day (\(\mu g/\text{day}\)).


We used sources like ConsumerReports.com and the FDA's Total Diet Study to bring you the most accurate and wide-ranging list of foods that have been tested for lead - and we're always adding more!

A product's parts per billion (PPB) is a lab number; your real risk tracks with the (\(\mu g/\text{day}\)) that you ingest. This number gives you a true measure of the total amount of lead you are getting from the food you consume.

Use this handy chart to get a visual representation of your exposure, and even compare against historical averages.

We add the real drivers.
For many people, non-food sources (dishes, dust, paint, soil) dominate BLL. Layer those in and watch the BLL change immediately.
