Smog to the south and sand to the east: The fascinating world of China’s hidden exports just got bigger
posted Sunday, 22 May 2005
For many year, Japanese citizens have become resigned to the fact that only two things come from China; cheap goods and verbal abuse, and that while one of these things is desirable, the other is not, however, a recent report by a Japanese Environmental science institute now suggests that there may be another import being carried from China that may prove to be desirable, at least if you sufferer from hay fever.
A recent scientific produced by a team environmental scientist at the Yamanashi Institute of Environmental Science, 甲府市 (Kofu City), 山梨県 (Yamanashi Prefecture), suggests that levels of hay fever causing pollen in Japan are noticeably lower when levels of yellow sand, blown in from China and Mongolia, are higher. The report further noted that the inverse is true, with low levels of Chinese and Mongolian yellow sand corresponding to high levels of pollen. The report also revealed that levels that levels of sand and pollen appeared to follow a distinct cycle, waxing and waning over a 10 year period.
In addition to announcing the apparent link between yellow sand and pollen, Koshimizu Satoshi, the lead scientist involved with the report, suggested that the sand-pollen cycled appears to resemble the cycle of sunspot activity, though Koshimizu added that the apparent similarities in cycles had yet to be investigated by the institute.
Kufu, the home of the Yamanashi Institute, is twinned with the city of成都 Chengdu in Sichuan province, China
