Abstract

In order to preserve the World Heritage sites, it is important to focus not only on naturaldestruction of rivers and vegetation, but also on pollution from the atmosphere. We analyzed theseasonal variation of ozone concentration and intensively observed NO3 - concentration in the UruiRiver and Shiba River systems in Fujinomiya City and its vicinity, where Shiraito Falls, a propatyof the World Cultural Heritage, is located. The three-year average of the one-hour ozoneconcentration was 28.6 ppb, which was almost the same as that of Tokyo Tower. Seasonalvariations were classified by the 24 solar terms, and compared to Tokyo Tower, the seasonalvariations tended to be higher from August 7 to 22. The average NO3 - concentration in the riversof the Juni River and Shibakawa River systems was 101 μmol/L. The NO3 - concentration in therivers was higher at lower elevations, but was relatively high at Shiraito Falls, at 146 μmol/L,despite its higher elevation. Shiraitono Falls, a World Cultural Heritage site, is considered to beestablished based on the site's favorable natural resources. However, it is also considered thatexamining whether the natural resources meet certain environmental standards, the atmosphericenvironment including dry deposition and water quality, and passing them on to future generationsas clean water will also help protect the World Cultural Heritage.
