13 The aim of this study is to develope advanced techniques for analysis of 
   toxic substances in polluted soils.  From the point of view of preventing 
   human health and ecosystem from being polluted by toxic substances from 
   industry and anthropogenic pesticides, 25 chemical materials were designated 
   as items requiring surveillance.  The purpose of this project is to advance 
   techniques for analysis of surveillance items solubilized from polluted 
   soils, such as antimony, molybdenum, nickel, boron and so on. 
   This year we present noble analytical techniques for characteristics and 
   determination of antimony solubilized from the artificial synthesized and 
   polluted soils.

13 This study is planned as a five year project started from FY 1995 to elucidate   the more appropriate arrangement of lands to be reclaimed in the bay together 
   with the appropriate redistribution or reduction of existing effluent 
   discharges into the bay by carrying out simulation experiments with hydraulic 
   and numerical models as assessment tools.
   This study also aims to establish effective measures or technologies for the 
   bay to compensate the unfavorable development impacts and to restore or 
   enhance the environmental capacity of the bay itself based on the field 
   survey for substance transport and assimilation processes in the bay and on 
   the simulation experiments with hydraulic and numerical models for tidal 
   flow control measures such as structure construction or topography 
   modification on the bay bottom.  The rational application of ecosystem model 
   is the other task of this study to evaluate the ecological effects of these 
   measures and to round off this study at its final stage.

13 In a semi-enclosed sea such as at Seto Inland Sea, eutrophic level of the 
   water has been progressing by increasing of organic materials that discharged 
   from a land or due to excessive primary production in a sea. In the eutrophic 
   sea, occurrence of red tide or shellfish toxification has frequently done 
   considerable damage to fish and/or shellfish culture. When it blows hard, 
   wind-induced strong mixing occurs in the sea and dense nutrient salts and 
   cysts curl up from bottom layer of the eutrophic sea. Diffusion of these 
   materials often plays important roles of a trigger in occurrence of read 
   tide and shellfish toxification. The purpose of this task is to make clear 
   how the wind-induced mixing of water has the influence on ecosystem in the 
   semi-enclosed sea.
