PURPOSE: A dynamic alarm issuing method of an organism particle monitoring device is provided to minimize a wrong alarm even though the number of dust and temporal change quantity of dust are high. CONSTITUTION: Particle information is inputted from an organism particle monitoring device(S100). An effective organism particle maximizing value is calculated from the particle information(S200). Whether the effective organism particle maximizing value exceeds concentration alarm criteria or not is determined(S400). When the effective organism particle maximizing value exceeds the concentration alarm criteria, an alarm signal is issued(S500). [Reference numerals] (S100) Acquiring data; (S200) Calculating the maximum value of effective organism particles; (S420) Exceeding an alarm criteria of relative concentration; (S440) Exceeding an alarm criteria of long-term low concentration; (S460) Exceeding an alarm criteria of short-term high concentration; (S520) Issuing the alarm of the relative concentration; (S540) Issuing the alarm of the long-term low concentration; (S560) Issuing the alarm of the short-term concentration
