Investigation of off-site airborne transport of lead from a superfund removal action site using lead isotope ratios and concentrations

•Measured Pb concentrations to trace Pb migration in an urban environment.•Measured Pb isotope ratios to trace Pb migration in an urban environment.•Off-site Pb concentrations and isotope ratios in the Staten Island area were similar to previously reported data.•Results indicated minimal off-site migration of Pb.
