In March 1993 we investigated the distribution of level SPM (Suspended Particulate Matter) inside and outside the homes closely located along the major arterial Roads in Tokyo. We surveyed 50 homes a week, a total of 150 homes for three weeks. Coarse(≥ 2.5㎛) and fine (≤ 2.5㎛) particles were separately collected by using portable aerosol samplers. Average levels of air pollutant had means of 23.6㎍/㎥ (indoor coarse particle), 35.4㎍/㎥ (indoor fine particle). Indoor smoking and the use of unvented heaters apparently increased level of fine particle. Indoor climate was found to be also influenced by the house structure. The increase of this pollutant level due to smoking or heating were observed in reinforced concrete because of the air tightness. By excluding the effects of smoking and heating, indoor fine particle was found higher in Homes which were closely (within 20m) located along the roads. The present result indicate a possible association between the distance from the roads and the level of fine particle.

Water to provide for human use will be critical problem we face for next century and should be major branch of an earth science. It has been anticipated that consumption of water in Korea will have outstripped available resources before 2006. Already water shortage was reported in a tributary of the Nakdong river. Water supplies from downstream area of this river such as Pusan and Kyung-Nam, we heard, have become severely contaminated by human and industrial waste products. To solve these problem and make preparations for a waterway, we propose 58 dams located upstreams, whose storage of water amount to 1.4 billion tons. By these dams, fresh water can be obtained with small submerged area compared to the dams planned by government.
