Sampling and physico-chemical analysis of precipitation: a review

Environmental Pollution, 2002
Wet deposition is one of two processes governing the transfer of beneficial and toxic chemicals from the atmosphere on to surfaces. Since the early 1970s, numerous investigators have sampled and analyzed precipitation for their chemical constituents, in the context of "acidic rain" and related atmospheric processes.

Chemical and Statistical Analysis of Precipitation in Singapore

Water, Air, and Soil Pollution, 2001
The results of chemical analyses of precipitation samples collected in Singapore between August 1997 and July 1998 are presented. Major inorganic and organic ions were determined in 169 rain samples collected using an automated wet-only sampler. The daily sample pH values ranged from 3.49 to 6.54 with a volume-weighted mean of 4.50, and about 88% of ...

Chemical Waves and Periodic Precipitation Processes

1988
A nonlinear chemical reaction with sufficiently complex reaction mechanism, maintained far from equilibrium, may show the phenomenon of chemical waves or fronts which are traveling concentration gradients 1,2,3,4 Chemical waves may occur in a variety of systems, including oscillatory reactions or reactions in a stable stationary state with so-called ...
