Abstract

Laboratory (n = 30) and field (n = 89) experiments were conducted using the water surface sampler (WSS) to investigate the air-water exchange of formaldehyde (HCHO). Average gas-phase overall mass transfer coefficients (K,) calculated using concurrently measured gas-phase fluxes and air concentrations were 0.58 +/- 0.21 and 0.25 +/- 0.12 cm s(-1) for laboratory and field experiments, respectively.
