Measurements were carried out in the Salvador area, Bahia, 13°S, 38 ° W) both at the seaside and 500 m away from it as well as at 270 km inland, in a rural area, during March-April 1988. Gaseous H20 2 was collected by cryogenic and rain by wet only sampling. Analyses were performed with the peroxyoxalate chemiluminescence method, employing a compact field apparatus. The measured gas phase concentrations ranged from 0.2 to 3.9 ppbv compared to 0.01-0.6 ppbv obtained from measurements with similar methodology in Dortmund (51°30'N, 7°30'E), F.R.G, during summer. The corresponding concentration ranges in rainwater are 0.9-6.8 ppmw (Bahia) and 0.1-2.2 ppmw (Dortmund, summertime). Gas/liquid H202 equilibrium during rain events is only attained at precipitation rates below 1 mmh -1.Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2012-01-12T16:05:48Z No. of bitstreams: 1 s2.0-0960168690901176-main.pdf: 480546 bytes, checksum: ba3ab45891046d05f39037932944d234 (MD5)Made available in DSpace on 2012-01-12T16:05:48Z (GMT).
