PM2.5

Abstract

PM 2.5 or Particulate Matters smaller than 2.5 micron that cause health problems as we just have heard about nowadays actually exist and gradually accumulated from several years ago up until now. This condition occurs every year but it seems to be very tough this year. That’s because it happens sooner than usual, early January instead of mid-February. The lengthier period the more trouble it causes. Those who have respiratory syndrome, heart diseases or vascular diseases are at risk of getting worse thus should avoid the areas where PM 2.5 level are over the standard. If it is necessary to enter the polluted areas, proper mask must be worn. This article also points out meteorological factors that contribute to this condition which will be beneficial for monitoring and may lead to finding sustainable solutions in the future.
