<p>PROBLEM TO BE SOLVED: To provide a multidirectional airborne salt collector and a multidirectional airborne salt survey method, in which a survey of an airborne salt amount from multi-direction is possible, and further, an effective airborne salt survey is possible without installing a large number of airborne salt collectors, and furthermore, an airborne salt amount according to the direction can be estimated precisely.SOLUTION: A multidirectional airborne salt collector 100 is configured to collect airborne salt according to airborne directions, and includes a hollow casing 200 constituted of side surfaces 210 and a bottom surface, and a roof material 300. In the inside of the casing, partition walls 220 are provided, and several compartments 230 partitioned with the partition walls 220 are formed. Collection windows are provided in the side surfaces constituting the compartments 230, and collection cloths 240 for collecting the airborne salt are installed in the collection windows. Alternatively, in the bottom surface constituting the compartments, vent holes are provided in the respective compartments. Further, several collection cloths 240 installed in the several compartments are respectively disposed facing in different directions.</p> |
