Exposure Calculator

Estimate your personal microplastic exposure across food, water, air, and lifestyle.

Scene 1 of 6 · The Basics

A few facts to set the scale. Body size changes the dose per kilogram, so the same exposure lands differently on different people.

Age

Answering for someone else? Use their age.

Infants and children take in more particles per kilogram of body weight, and cumulative exposure keeps climbing with age, so each range carries its own weight in the model. How this is scored

An infant (under 2) A child (2 to 17) An adult, 18 to 30 An adult, 31 to 45 An adult, 46 to 60 61 to 75 76 or older

Biological sex

Some studies report different microplastic concentrations in male and female tissue samples, though evidence for different intake is limited. The model applies a small weight graded as emerging evidence. How this is scored

Male Female Prefer not to say

Body weight

Exposure is scored per kilogram of body weight, so this sets the scale.

The same daily particle intake lands harder on a smaller body, so the model scales exposure by weight. A range is enough; precision beyond the band does not change the score. How this is scored

Under 88 lb (40 kg) 88 to 110 lb (40 to 50 kg) 110 to 132 lb (50 to 60 kg) 132 to 154 lb (60 to 70 kg) 154 to 176 lb (70 to 80 kg) 176 to 198 lb (80 to 90 kg) 198 to 231 lb (90 to 105 kg) 231 to 265 lb (105 to 120 kg) Over 265 lb (120 kg)
