Dust fall jar which is recommended by ASTM (America Society for Testing and Materials) for collecting dust in month period whereas high volume sampler is recommended by Unites States Environmental Protection Agency and National Environment.Board is normally used for 24-hour sampling period. The goal of research is to study the trend of collected by high volume sampler and dust for jar and relation of dust and calcium, Which is the major component in cement powder collected by the two apparatus with distance and direction in Southwest monsoon and Northeast monsoon. Monthly sampling by dust fall jar was done for one year while short. Period of 24-hour sampling by high volume sampler was done in February and March during Southwest monsoon and in December during Northeast monsoon.
