摘要:
Japanese cedar (Cryptomeria japonica) pollinosis (JCP), affecting more than a quarter of the Japanese population, is a significant public health problem, due to its negative impact on daily activity. JCP patients have used the four-stage daily pollen deposition information based on the pollen monitoring over 20 years. However, the procedure for monitoring pollen was recently changed dramatically, to hourly average pollen concentration monitoring. In that type of monitoring, JCP patients cannot identify pollen exposure level because the relationship between hourly average pollen concentration and daily pollen deposition is unclear. Based on the parallel monitoring of concentration and deposition counts that we performed in Niigata prefecture, Eastern Japan, we found that the relationship between the daily pollen deposition (pollen cm(-2) day(-1)) and the daily-average pollen concentration (pollen m(-3)) calculated from hourly average pollen concentration was not only statistically significant but also consistent with the aerodynamic properties of pollen. Using the relationship, we proposed new range criteria of hourly average pollen concentrations corresponding to the four stages of pollen deposition. Additionally, the conversion of pollen deposition to pollen concentration made the long-term trend analysis of the daily-average pollen concentration possible in this study area, and an increasing trend was identified at one site.
