It's Springtime. Clean Out Your Closet, Especially the Clothes with LEAD in Them.

Parents Beware: Fast Fashion Could Harm Your Kids

Spring cleaning? Good. While you're at it, check the tags on your kids’ shirts because researchers just revealed something wild.

At a recent meeting of the American Chemical Society (ACS), undergraduate researchers from Marian University presented findings that many kids clothes contains an unwanted, toxic ingredient: lead.

They tested fabric from children’s fast fashion shirts sold by multiple retailers and found that every single sample exceeded U.S. federal regulatory limits for lead. Every. Single. One.

Let me say that again. Not some of them. All of them.

The researchers also estimate that even briefly chewing on these fabrics (which young children tend to do) could expose them to dangerous lead levels.

The U.S. Consumer Product Safety Commission sets a lead limit of 100 parts per million for children’s products which includes toys, clothing, and more. These shirts blew past that.

Unfortunately a good wash doesn’t get the lead out. The metal binds with dyes and fibers in a way that a typical washing machine cycle cannot eliminate.

And here’s the thing: we already know what lead does to children. Lead exposure at any level can cause behavior problems, brain and central nervous system damage, and a host of other devastating health effects. Children under 6 are considered the most vulnerable.

So why is it in their clothes?

Some manufacturers use lead(II) acetate as a cheap way to make dyes stick to fabric and keep colors bright and long-lasting. Cheap for them. Not so cheap for your kid’s developing brain.

The researchers didn’t stop at measuring lead levels. They simulated stomach digestion to calculate what a child could actually absorb, modeling the kind of mouthing behavior that young children do every day, like sucking, holding, or chewing on fabric.

Their findings suggest that this kind of exposure could exceed the daily lead ingestion limit set by the FDA. Kids chew on their shirts. We all know this. And apparently the industry has been betting that no one was paying attention.

Brightly colored items, especially reds and yellows, showed the highest lead levels, though no color was completely off the hook.

Now here’s what really gets me. Safer alternatives already exist such as natural mordants from plants like oak bark, pomegranate peel, and rosemary, which are environmentally safe. But switching costs money. And without pressure from consumers or policymakers, the industry has zero incentive to change.

This is the same story I’ve seen my entire life. The harm is known. The alternatives exist. But until someone forces the issue, nothing moves.

The good news? This research was driven by a principal investigator who got into this work after her own daughter showed elevated blood lead levels, along with undergraduate students on pre-medicine tracks who saw an overlooked health issue and decided to act. That’s how change starts. Regular people who refuse to look away.

So here’s what I’m asking you to do: share this. Talk about it. Ask the retailers where your kids’ clothes come from and how they’re dyed. Demand answers. Because as one of the student researchers said, “Everything that we’re doing is only important and helpful if we talk about it.”

She’s right. So let’s talk.

What To Do Now

Listen, I know a lot of parents need budget-friendly options for fast-growing kiddos. I’ve been there! So here’s a few alternatives to consider.

Buy secondhand first. Thrift stores, consignment shops, Facebook Marketplace, ThredUp, and Poshmark are goldmines for kids’ clothes. Since children outgrow things so fast, secondhand items are often barely worn. You can frequently find name-brand, better-quality pieces for a fraction of the price.

Organize or join a clothing swap. Many communities, schools, and parent groups host kids’ clothing swaps where families trade outgrown items. It costs nothing and you walk away with a new wardrobe.

Shop end-of-season sales at quality retailers. Stores like Land’s End, L.L. Bean, and similar brands run deep discounts (50–70% off) at the end of each season. Buy the next size up in coats, boots, and basics for next year. These items are built to last and often hand-me-down well.

Embrace hand-me-down networks. If you have friends or family with slightly older kids, get yourself on the hand-me-down list. Offer to return the favor when your child grows out of them.

Focus spending on quality basics, not trends. Kids don’t need trendy pieces. They need sturdy everyday basics. Spend a little more on well-made jeans, a good coat, and durable shoes, then fill in the rest secondhand. Trendy tops are exactly what fast fashion does worst from a safety and durability standpoint.

Stick to neutral and muted colors when buying new. Based on the research in the article, brightly colored items, reds and yellows especially, showed the highest lead levels. Choosing more muted tones when buying new clothing adds a small layer of caution while the industry catches up.

Wash new clothes before wearing them. This is a good general rule regardless of brand. It won’t eliminate lead if it’s embedded in the fibers, but it can reduce surface-level chemical residues from manufacturing and shipping.

Look for OEKO-TEX certified clothing. The OEKO-TEX Standard 100 certification means a fabric has been tested for harmful substances including heavy metals. It’s not a guarantee, but it’s a meaningful signal that a brand is paying attention to what’s in their textiles.

The bottom line is that kids’ clothes don’t need to be new to be safe, and often the older, more durable pieces from quality brands that end up at thrift stores are better than what’s being manufactured cheaply today.
