A Startling Estimate

Researchers estimate that over an average lifetime of 79 years, a person may ingest up to 20 kilograms of plastic — roughly the equivalent of two green garbage bins. While research on microplastics is still evolving, scientists have developed this estimate by breaking down average intake over time.

How Researchers Calculated This

Studies suggest that microplastics are consumed regularly through food, water, and air. Based on current findings, estimated intake includes:

• Per week: About 5 grams — roughly the weight of a credit card
• Per month: About 21 grams — similar to half a bowl of rice
• Per year: About 250 grams — equivalent to a full dinner plate
• Per decade: About 2.5 kilograms — about the size of a standard life buoy
• Over 79 years: About 20 kilograms — comparable to two green recycling bins

These estimates help illustrate how small, repeated exposures can accumulate over time.

Call to Action

The question is no longer if we are exposed — but how much and what we can do about it.
