１９８８～１９８９年对闽江一带８个蚬埕的蚬仔、水质、基质进行铅（Ｐｂ）、镉（Ｃｄ）、锌（Ｚｎ）、铜（Ｃｕ）、汞（Ｈｇ）的污染程度调查。３６份蚬仔样品各项指标中有３份Ｈｇ超标，其他均符合有关标准。闽江上游采集的蚬体中Ｐｂ、Ｃｄ、Ｈｇ的含量比下游高，而Ｃｕ、Ｚｎ则反之。黄色蚬仔Ｃｄ污染程度比黑色蚬仔高。大蚬仔Ｃｕ含量比小蚬仔高。蚬仔的污染程度与水体、基质中重金属含量无相关关系。
From 1988 to 1989, the contamination levels of Pb, Cd, Zn, Cu and Hg in eight 蚬 埕 埕,, water quality and matrix of Minjiang River were investigated. Thirty-six samples of Zaizi samples had Hg exceeded the standard, others were in accordance with the relevant standards. The contents of Pb, Cd and Hg collected in the upper reaches of Minjiang River are higher than those in the lower reaches, while Cu and Zn are the opposite. Yellow 蚬 Tsai Cd pollution levels higher than black 蚬. Tai Chi Tsai Cu content than small Chi Tsai high. Aberdeen pollution levels and water, matrix no correlation between heavy metal content.
