《向阳红九号》调查船的空气微生物

Correlation of Nutrent Salts and Microelements to Huanghua Red Tide

本文对《向阳红九号》调查船做了空气微生物的监测，结果表明：平均全船舱内空气微生物总量、空气真菌含量、空气真菌量占空气微生物总量的百分数分别是３７３０．９ＣＦＵｍ－３，１６８．１ＣＦＵｍ－３和１５．３×１０－２。尚未超过国家对客船规定的卫生标准，但有２１×１０－２的测定结果已超标。两次测定间的差异主要由空气扰动状况所致；层间及舱室间的差异是因人员工作生活习惯等造成的。结果还表明，较好条件的上层乃至全船舱室大有改善环境卫生条件的必要。

Through a study on monitoring water quality along the coast of Huanghua City, Hebei Province during the red tide period from in 1989 to 1992, this paper discussed the relation of the contents of nutrient salts and microelements to the occurrence of red tide. The results show overabundance of nutrient salts has brought about the multiplication of red tide algae and an excess of microelements (Fe and Mn) has been an inducing factor of the formation of red tide along the coast of Huanghua.
