The concentrations of Cr, Ni, Cu, Zn, As, Cd, Pb, and Al in suspended particles were measured, and temperature, salinity, flow velocity and direction during a tidal cycle were observed before and after Typhoon Fung-wong at six stations in Quanzhou Bay, respectively. The comparison results show that, after the typhoon, the salinity in Quanzhou Bay decreased, whereas the concentrations of heavy metals increased by a factor of between 2 and 10, and the high heavy metal concentration corresponded to the low value of ratio between heavy metals and Al (HMs/Al), suggesting that these increased heavy metals were mainly from natural sources. Instantaneous unit width flux calculations for heavy metals at different stations indicate that sediments are an important source of heavy metals in suspended particles under the influence of typhoon, which has significantly contribution to understanding the impact of typhoons on the heavy metal pollution in the coastal area.
在六个泉州湾站位分别测量了台风“凤凰”前后悬浮颗粒中 Cr、Ni、Cu、Zn、As、Cd、Pb 和 Al 的浓度，并观测了整个潮周期的温度、盐度、流速和流向。结果表明，台风过后，泉州湾盐度降低，而重金属浓度增加了 2 到 10 倍，重金属与 Al（HMs/Al）比值低对应高重金属浓度，表明这些增加的重金属主要来自自然源。不同站位重金属瞬时单位宽度通量计算表明，在台风影响下，沉积物是悬浮颗粒中重金属的一个重要来源，这对了解台风对沿海地区重金属污染的影响有重要意义。
