※About negative measurements
When microparticulate matter concentration is very low, it may be in negative value, but, by errors of measuring machine, one hour value decides to treat negative value as the same value including verge calculating the daily mean. As for the detailed explanation, please see page of Ministry of the Environment.
※We can read data in portable site.
◎Of PM2.5 pass, and, as for the daily fluctuations graph, please see this.
With microparticulate matter (PM2.5), diameter of particle (particle size) is defined as very small particles less than 2.5 micrometers of (μm) (0.0025mm) among existing particulate matters in the atmosphere. It is easy to get deep into the lungs, and it is told respiratory systems to cause disease.
Environmental standards (established in Environmental Basic Law Article 16 with "standard that it is desirable to be maintained in we protect health of person and keeping living environment in good condition".) are as follows.
(1) Yearly average levels being less than 15 micrograms/cubic meter of (μg/m3).
(2) The day means being less than 35 micrograms/cubic meter of (μg/m3).
In addition, when the excess days of the day mean are from 0 days to seven days and, as for what is judged to have adapted to environmental standard, yearly average levels are less than 15 micrograms/cubic meter of (μg/m3). When we satisfy these two conditions at the same time, we are judged "to have adapted to environmental standard". Detailed glossaries such as environmental standards, please refer to this.
