Dining out may boost exposure to certain potentially toxic pollutants, a new study finds. Researchers measured higher levels of these phthalates (THAAL-ayts) in the bodies of people who recently dined out than in those who had been eating only foods that had been cooked at home.

Explainer: What is a hormone?

Phthalates are found in many products, notably cosmetics, floor tiles and certain types of plastics. These chemicals also are used in food packaging. Many studies over the past few decades have shown phthalates can mimic the action of certain hormones. (Such pollutants are known as endocrine disruptors.) Hormones are important chemicals that help direct the activity of cells throughout the body. The effects of phthalates on hormones may alter how reproductive organs develop in infants and children. These chemicals might even impact the timing of puberty, animal studies have shown. That’s why environmental scientists recommend limiting exposures to phthalates.

Yet doing that isn’t easy. Why? Phthalates are everywhere — in the air, water and soils. They are the most common industrial pollutant in the environment. People inhale and ingest tiny quantities every day. These pollutants can even enter the body through the skin.

Ami Zota is an environmental health scientist at George Washington University in Washington, D.C. She studies how pollutants can affect health. And her team knew that food packaging can be a notable source of exposure to some phthalates.

Explainer: What are endocrine disruptors?

“We all know that certain foods are more nutritious than others. But there are other ways that food choices can affect health,” says Zota — and in a potentially negative way. That’s why her team wanted to look for any trends between where people get their food and the amounts of phthalates in their bodies. Such information could be important, she says, in guiding the behaviors of people who want to limit their exposure to phthalates.

To find out where people were eating, the researchers tapped into results from a large national survey. Known as the National Health and Nutrition Examination Survey, it included data collected between 2005 and 2014 from more than 10,000 U.S. children, teens and adults. It asked each person what they had eaten in the past 24 hours. Each participant also provided a urine sample.

At least six in every 10 of these people (61 percent) reported dining out at least once in the past day. Such meals might have been purchased in a cafeteria, from a fast-food place or in a sit-down restaurant. Children and teens ate out more than adults did. Teens were more likely to eat fast food. Younger children were more likely to eat cafeteria food. Adults over age 60 were most likely to report having eaten at home only.

The researchers compared such data to levels of phthalates found in someone’s urine. People who reported eating out in the past day had 35 percent more phthalates in their urine compared with people who ate only food purchased at a grocery store. Among teens, phthalate levels in those who dined out were 55 percent higher than in teens who had eaten only food from home.

The new study’s findings are concerning, Zota’s team says. People are dining out more than ever. That could mean ever higher exposures to these pollutants.

The researchers reported their findings March 29, 2018 in the journal Environment International.

The study is the first to assess the link between phthalate exposure and thyroid function in children over time. Results appear the journal Environment International.

Understanding Diethyl Phthalate: Uses, Safety, and Environmental Impact

Chemical ingredients play a huge role in our everyday lives, often without us realizing it. One such ingredient is Diethyl Phthalate (DEP)—a clear, oily liquid commonly used in a wide range of consumer and industrial products. While it rarely gets public attention, DEP is a substance worth understanding, especially as conversations around chemical safety and environmental impact continue to grow.

What is Diethyl Phthalate?

Diethyl Phthalate is an organic compound belonging to a family of chemicals known as phthalates. These chemicals are typically used to make plastics more flexible, though DEP is a bit different. Instead of softening plastic, it is mostly used as a solvent and fragrance carrier.

Common Uses of DEP

DEP appears in many everyday items, though usually in very small amounts. Some common uses include:

Fragrance carrier in perfumes, cosmetics, and personal care products

Solvent in inks, dyes, and certain types of coating

Plasticizer in some cellulose-based plastics

Component in mosquito repellents

Additive in household and industrial formulations that require stability and uniformity

Because of its ability to dissolve and stabilize other substances, DEP has become widely used across multiple industries.

Is Diethyl Phthalate Safe?

Safety concerns around phthalates often raise questions about DEP. However, it is important to note that not all phthalates behave the same way.

Current scientific evaluations generally classify DEP as low toxicity, especially compared to other phthalates. It does not appear to strongly disrupt hormones, and studies suggest it has a lower potential for bioaccumulation.

That said, certain considerations remain:

Skin exposure from personal care products is common but typically minimal.

Ingesting or inhaling high levels—mostly relevant in industrial settings—may cause irritation or discomfort.

Regulations in many regions continue to monitor DEP usage, encouraging safer practices and limiting exposure where unnecessary.

For everyday consumers, typical exposure levels from cosmetics, fragrances, or household products are generally considered low risk.

Environmental Impact

Once released into the environment, DEP can break down relatively faster than many other phthalates. It dissolves in water more easily and tends to degrade through natural processes such as sunlight and microbial activity.

However:

High concentrations may affect aquatic life.

Continuous release into waterways—from industrial or large-scale product disposal—remains a concern.

Waste management and responsible disposal practices help reduce long-term environmental impact.

Why Is DEP Still Used?

DEP remains popular because it is:

Effective as a solvent and fragrance carrier

Stable and resistant to degradation in products

Less harmful compared to many traditional phthalates

Versatile, allowing manufacturers to maintain product performance

At the same time, increasing awareness around chemical safety is pushing for more transparency and research into all phthalates, including DEP.

Conclusion

Diethyl Phthalate is one of those behind-the-scenes chemicals that quietly supports the stability and performance of many everyday products. While it belongs to a class of chemicals that often raises concerns, current evidence suggests that DEP itself is relatively low in toxicity and manageable in terms of environmental impact. Still, ongoing research, responsible usage, and consumer awareness remain important.
