Microplastics and nanoplastics have been detected in drinking water, food, household dust, human blood, lungs, reproductive organs, arteries, and even brain tissue.

While scientists continue studying their long-term health effects, reducing unnecessary exposure is considered a sensible precaution.

The Microplastics Exposure Assessment examines common sources of exposure and everyday habits that may increase your contact with microplastics and nanoplastics.

This assessment estimates your potential exposure based on your daily habits. It is not a medical diagnosis and cannot measure the actual amount of plastic in your body.

For current scientific information about microplastics and nanoplastics in food and human exposure, see the U.S. Food and Drug Administration’s overview.

Drinking Water

Microplastics have been detected in bottled water, tap water, and many beverages. Your source of drinking water, how beverages are packaged, and whether you use water filtration can all influence your potential exposure.

Answer the following questions based on your typical habits during the past year.

There are no right or wrong answers. Choose the response that best reflects your usual daily habits.

Food

Food is considered one of the largest potential sources of microplastic exposure. Packaging, food storage, food preparation, canned foods, and highly processed foods may all contribute to exposure.

Consider your normal eating habits rather than occasional events.

Think about what you normally eat over the course of a typical week, not just today.

Household Exposure

Microplastics can accumulate inside homes as dust released from carpets, furniture, clothing, and household products. Cleaning habits and indoor air quality may influence the amount of plastic particles present in your environment.

Answer based on your primary residence.

If you spend most of your time in one home, answer using that location.

Personal Habits

Some everyday habits can increase contact with plastics through food, beverages, clothing, and other consumer products. This section focuses on behaviors that may contribute to long-term exposure.

Answer honestly based on your normal routine.

Choose the answer that best describes your typical behavior over the past year.

Cooking Practices

Heating plastics can increase the release of microscopic plastic particles into food and beverages. Your cookware, food containers, utensils, and beverage containers may all influence exposure.

Consider how you usually prepare meals at home.

Think about your regular cooking habits rather than occasional situations.

Lifestyle

Lifestyle choices, workplace activities, and everyday purchasing habits can affect your overall exposure to microplastics. This final section looks at broader behaviors that may contribute to cumulative exposure.

Answer each question based on your current lifestyle.

Your answers will help estimate your overall exposure pattern across multiple areas of daily life.
