塩害に関する基礎的研究(第二報)巨大海塩粒子連続サンプラーの試作と測定例

Abstract

The design and use of a continuous sampler, a jet impactor of continuous operation, by which giant sea-salt particles may be automatically sampled for 2 or 4 days, are -described. There ~re two models: Model I is for ground use, and Model II is 'forairplane use. An example of the time series data for 2.5 hours provided by the ModelI sampler is presented, and a criterion for distinguishing statistical and real fluctuationsin the number concentration is dis~issed. Also, reinits provided by the Model II samplerare compared with results by simultaneous operation of 1mm-film ribbon exposure method, and the efficiency of sampling is discussed.
