Weekly-fortnightly ozone (O 3 ) concentrations measured by passive sampling at 81 forest monitoring plots in France, Italy, Spain and Switzerland over the period 2000–2002 were used to estimate the cumulative exposure index AOT40. The estimation method is based on a deterministic model which describes the O 3 daily profile as a function of relative altitude (the difference between...
Passive sampling of dissolved pollutants in water has been gaining acceptance for environmental monitoring. Previously, an integrative passive sampler consisting of a C 18 Empore ® disk receiving phase saturated with n-octanol and fitted with low density polyethylene membrane, was developed and calibrated for the measurement of time weighted average (TWA) concentrations of hydrophobic...
