Fast fashion clothing can contain high levels of lead, which has been linked to behavioral problems, brain damage, and long-term health issues. Preliminary research from the American Chemical Society has revealed that some fabric used in clothing from discount retailers and fast-fashion brands exceeds lead limits. The research also found that 11 shirts in various colors from four retailers exceeded the US Consumer Product Safety Commission’s allowed limit of 100 parts per million, with brighter colors like red and yellow having higher amounts. The team hopes this will lead to more thorough screening of children’�s apparel and safer alternatives for the dyeing process. However, regulations on lead levels in clothing are difficult due to the high volume of imported goods.
