[O02-P46] Chemical Substances and its components in rainwater
Keywords:meteorology, atmospheric pollution, acid rain
1 : Gather rainwater with “raingoround” (“raingoround“ is a device developed by HORIBA factory which can gather rainwater by 5mm.
2 : Analyze rainwater with ion chromatograph system.
1 : Rainwater on Dec 11 had thick constituent concentration of the sea (Na or Cl).
→Rainwater brought by south wind have more sea water than that brought by north wind.
2 : Through four times experiments (Dec 11, 13, Jan 18, 29) as rain down, the concentration becomes low.
3 : We can find the tendency that the conductance becomes low steadily while pH doesn’t have any clear tendency.
→The rain has a lot of air pollutants in the beginning.
*After this experiments we want to study continuously how weather condition affects substances in rainwater and each amount of them.
