For hazardous air pollutants, environmental monitoring is required for grasping hazardous air pollutants as
to whether they are detected in the environment and grasping the environmental concentration level aroundthe general environment and the emission source, but few cases of atmospheric monitoring of mostsubstances. Since it is necessary to continuously monitor and obtain measured values. We studied thedevelopment of AIQS-DB (fully automatic identification / quantitative database system), analyze
multicomponent substances efficiently, of VOCs targeted for hazardous air pollutants of Air Pollution
Control Law, and 59 substances AIQS - DB was developed.

established. Therefore, we aimed to obtain new density index using the traces of digging up by wild boar
and to elucidate the preference of the local environment of wild boars. As a result, the density index using
the traces and Catch Per Unit Effort obtained by camera trap had a positive correlation. Therefore thedensity of the traces of digging per unit distance can be reliable as the density index of wild boar. And thetraces of digging were found in high probability at sites where the planting rate on the ground was not toohigh and where many ferns and forb were found.

Millipede feeds litter mainly, but their abundance is small to amount of food resource in field. In this study,
I considered method that can collect millipede more efficiently and recommended combination of pit-falltrap and hay trap. In addition, I observed interspecific difference in feed preference due to thedecomposition stage of litter by feed preference experiment. It was suggested that abundance of millipede
was influenced by amount of actual food resource which is different from apparent.

I mixed citric acid and calcium carbonate and left it. I analyzed it after that. A result that removal rate fell ina mixed system of silicon and calcium was provided in the study. It was also confirmed by the removal withthe citric acid that produced precipitate was different with time.
In addition, I defined the pollution cloth as the cloth which attached calcium, silicon and phosphate. I
washed the pollution cloth, examined removal performance.

surfactants by the fine bubbles shown when the mechanical power of the washing machine is weak. And it
was found that the fine bubbles are effective for raising the removal rate of the surfactants.

In 2016, we developed a LUR model for nitrogen dioxide (NO2) in Yokohama,Japan based on the annual mean of NO2 concentrations from April 2005 to March 2006, but we found thatit should be necessary to check whether the predicted values at the unmeasured areas are correct or not.
This study presents the results of validation study of the developed LUR model, and discusses theapplicability of the model to air pollution epidemiologic study in Japan.

Improvement of decontamination
efficiency of radiocesium byreplacing wood chipon the forest floor. To increase decontamination efficiency, it is necessary to increase fungi. We conducted
experiments to improve the decontamination efficiency by replacing the wood chips. As a result,decontamination efficiency was improved by replacing, and about 1.5% of radiocesium in the soil could beremoved. It was thought that the supply of carbon by replacing resulted in improvement of decontamination
efficiency.

Examples of unregulated substances whose toxicity rises due to degradation in the environment have beenreported, and GC/MS simultaneous analysis method for the PRTR Law compounds and its
photolysis/hydrolysis products has been developed by the past research.

In this study, the reaction rate ofphotolysis of parent substance in water was determined, and the relationship between parent - childsubstance detection in river and degradability was investigated. As a result, the detection rate of childsubstances tended to be higher for substances with higher degradability of parent substances, and it wasthought that child substances were derived from parent substances.
