The river water flows through from the Aizu region to the Sea of Japan. In the aga river basin, the bioaccumulation of fish are well recognized.
Then the median of omnivorous Cyprinidae shows about 1. The box plots indicate inter-quartile ranges of these data. Bars are into the each box indicate the each median. To the south west of Fukushima prefecture, there lies the Kanto region which as well as containing the metropolitan prefecture of Tokyo also comprises Ibaraki prefecture, Tochigi prefecture, Gunma prefecture, Saitama prefecture, and Chiba prefecture.
Therefore, there are not only many source points of water springs and many rivers and streams but also high density water network systems of irrigation canals and urban water systems. Freshwater fish inhabit all types of water systems. As a result, the level of freshwater contamination can be taken as an index of the environmental contamination of the freshwater ecosystem. The isogram map Fig. Each isogram center points are each prefecture's capital city.
We found a relation between the distance from the power plant and the quasi-Cs contamination level of freshwater fish. Therefore, it is estimated that contamination of freshwater fish is extended to all prefectures in eastern Japan. The Japanese freshwater system is very high density as developed rice water paddy field, irrigation canal, urban water-system network.
Therefore, we have to think that the contamination of freshwater fish is widespread not only in river basins but also all over the ground included all types of water-systems, for example, agricultural and urban water systems. The isogram map shows the contamination tendency quite well. The contamination levels of the freshwater fish provide insufficient data and the knowledge of the path about bioaccumulation.
So, we will have to survey a more wide spread area and monitor bioaccumulation in each species level. In this paper we show the relation between distance and contamination levels by inverse regression analysis. The results indicate the effects of quasi radioactive cesium by the Fukushima accident look like less serious than those of the Chernobyl accident.co.organiccrap.com/147893.php

However, contamination levels are possibly higher than the Chernobyl as the cesium is concentrated by the water systems in limitation region. Water paddy field look like shallow pond saved mud included cesium Moreover, the cesium will distribute and concentrate by high density irrigation canal and urban water-system.
Therefore we must carefully and continuously monitor the contamination to the freshwater ecosystem and human health. Data of radioactive cesium of freshwater fish was analyzed by each local government according to the emergency food survey manual of radioactive substance The purpose of this manual is they avoid feeding high contaminated food it was defined by food security of emergency condition. Therefore, it is not aimed at collecting accurate data.
As a result, this data did not distinguish between cesium and cesium Therefore, the analysis of this paper calculated by quasi-Cs included Cs They used germanium semiconductor machine when they measured the radioactive cesium contamination of freshwater fish. The calibration is only Cs in per week. The range of radioactive cesium applied only Cs regression equation. The result, when the case included Cs is relatively much, the numerical value become over estimation.
The sample of freshwater fish was collected by each prefectural government by emergency policy of food security. The measure is using wet condition fish. Ayu and small fish was measured hole body, while big fish measured the part of food portion.
