3. Methodology
The sampling campaign was performed using three different types of equipment, according to the kind of environment.
Automated monitors for atmospheric environment were located at least 3 m above the street level. Basically, we used RAMA equipment and canisters were added for the VOC sampling. For the microenvironment measurements, canisters and 3M passive personal monitors were utilised. The 3M monitors were located just beside the corresponding canister. For the personal measurements, 3M passive personal monitors were used. The monitor was carried by the individual near his nose during all the monitoring period.
