Some fast fashion and low-cost clothing items for children may contain excessive quantities of lead, according to preliminary research presented by researchers from Marian University in Indianapolis at the ACS Spring 2026 conference of the American Chemical Society
“Fast fashion, i.e. the production of low-cost clothing items that rapidly follow fashion trends, has raised concern in recent years due to inconsistent quality controls and potential health risks,” the authors explain in the presentation of the work. “Among these risks, lead contamination in clothing is particularly alarming, especially for children. However, regulations on lead levels in clothing are difficult to enforce due to the high volume of imported goods.”
The team tested 11 children’s T-shirts purchased from four retailers active in the US market. The researchers reported that all samples analyzed exceeded the U.S. federal limit of 100 parts per million (ppm) total lead for accessible components of children’s products.
The colors most at risk
“We saw that the T-shirts we tested were all over the allowed limit of 100 ppm,” said one of the authors, Priscila Espinoza. Regardless of brand, fabrics in brighter colors, such as red and yellow, tended to show higher amounts of total lead than those in more muted tones.
The researchers also simulated gastric digestion in the laboratory and modeled the possible transfer of lead if the tissue is sucked or chewed, a behavior considered plausible in younger children. According to the authors, the results suggest that repeated exposure could exceed the daily limit indicated as a safety reference and, over time, make clinical monitoring appropriate. However, this is a modeling estimate and not the measurement of real levels in the blood of exposed children.
Exposure to lead is considered particularly risky for young children. The Centers for Disease Control and Prevention reminds us that there is no safe level of lead in children’s blood, while the EPA reports that children under six years of age are the most vulnerable also due to their frequent hand-to-mouth and object-to-mouth behaviors.
