title: Blood lead levels in NASCAR Nextel Cup teams.
abstract: This pilot study determines whether NASCAR racing teams demonstrate exposure to lead from exhaust by evaluation of blood lead levels (BLL). Participants were stratified by proximity to fuel exhaust or whether they worked on an engine. Each participant completed a self-reported survey recording demographics, lead exposure (occupational or in-home environment), and any physical symptoms of lead toxicity. Blood lead levels were then measured. BLL of 47 individuals ranged from 1-22 microg/dL with a median of 9.4 microg/dL. Nineteen of 47 (40.4%) had BLL > or = 10 microg/dL. Participants exposed to exhaust gas had the highest relative risks (RR) for elevated lead, followed by working on brakes and radiator repair. The RR of having an elevated BLL and self-reported adverse health outcomes or symptoms was increased. This study of NASCAR racing teams demonstrates lead exposure.
