Frequent Photochemical Smog and China's Air Pollution Countermeasures - July 20, 2007

**Frequent Photochemical Smog and China's Air Pollution Countermeasures - July 20, 2007**

Photochemical smog alerts have been frequently issued in the Kyushu and Yamaguchi regions, with 2007 seeing the first such alerts in a decade for Nagasaki, Kumamoto, Fukuoka, Oita, and Yamaguchi prefectures. The National Institute for Environmental Studies and other organizations have pointed out that polluted air from the coastal areas of China has significantly impacted the region.

In response to this issue, Fukuoka Governor Wataru Aso met with Foreign Minister Taro Aso to request immediate countermeasures. Since pollutants from China are directly affecting Japan's air quality, prompt action is necessary.

Photochemical smog occurs when nitrogen oxides and volatile organic compounds in the lower atmosphere undergo chemical reactions under sunlight, generating ozone. This can lead to respiratory problems and other health issues.

Moreover, the pollution situation in this region has worsened due to increased industrial activity and maritime traffic following the economic recovery, as well as stricter enforcement measures. According to the 2006 Marine Environmental Report, the number of confirmed pollution cases involving oil and waste was nearly double that of the previous year, with oil pollution and illegal waste dumping posing significant challenges.

Given this situation, cooperation between local governments and the national government is essential, and concrete countermeasures must be urgently implemented. Protecting the health of local residents requires swift and effective responses to photochemical smog and other environmental pollution issues.

This issue is not only a concern for Japan but also attracts international attention in the context of environmental protection. Strengthening cooperation with China will be a key challenge moving forward.
