Brake wear emissions are a major source of non-exhaust particulate matter, yet occupational exposure in brake pad standard laboratories remains significantly underexplored. Workers in these laboratories are exposed to high concentrations of airborne particles, including PM10, PM2.5, ultrafine particles, and toxic metals such as copper, iron, and antimony. These emissions can penetrate deep into the respiratory system, potentially leading to respiratory, cardiovascular, and systemic health issues. Despite growing environmental awareness, the specific risks faced by laboratory personnel are not sufficiently addressed in current occupational health standards. This letter underscores the urgent need for dedicated research and regulatory attention to this overlooked exposure pathway. Effective mitigation strategies such as local exhaust ventilation, high-efficiency filtration, use of personal protective equipment, and safer brake materials should be implemented to reduce health risks. By raising awareness of this issue, we aim to initiate informed discussion among researchers, industry professionals, and policymakers to enhance worker safety in brake wear testing environments.
