Monitoring of the Deposition of PAHs and Metals Produced by a Steel Plant in Taranto (Italy)

Table 2

Bulk deposition flux ng m⁻² d⁻¹ and the measurement uncertainty (SD) of each PAH for the urban background site. The sum of the PAHs detected ( PAHs) during sampling periods is listed in the last column.
