- Total peroxides and sulfate in rainwater in the Mexican eastern Pacific Ocean during the Climatic Experiment in the Americas Warm Water Pools A. Báez H. Padilla M. C. Torres R. Belmont R. García Biología sulfates rainwater Total peroxides Total peroxides were analyzed in 26 rainwater samples collected on board of the R/V El Puma of the NationalAutonomous University of México (UNAM) during the Climatic Experiment in the Americas Warm WaterPools (ECAC-1) over the eastern Pacific Ocean between 12 and 14° N, and between 98 and 100° W, fromMay 23 to 25, 2001. The volume weighted mean concentration of total peroxides was 13.1 ± 1.94 μM. Also,sulfate ion was analyzed. The volume weighted mean concentrations for sulfate and sea-salt sulfate were 0.76± 0.59 and 0.04 ± 0.06 mg L-1, respectively. Excess sulfate (non-sea-salt sulfate) represented 95% of the totalsulfate. The total peroxides concentration in rainwater correlated significantly with total sulfate and excess sulfate(0.560 and 0.586 at a p < 0.05, respectively) possibly because most of the excess sulfate and hydrogen peroxide,observed in the Mexican eastern Pacific Ocean, could have been produced from the oxidation of biogenic Total peroxides were analyzed in 26 rainwater samples collected on board of the R/V El Puma of the NationalAutonomous University of México (UNAM) during the Climatic Experiment in the Americas Warm WaterPools (ECAC-1) over the eastern Pacific Ocean between 12 and 14° N, and between 98 and 100° W, fromMay 23 to 25, 2001.
