研究了锌暴露对灰红树林白骨壤叶绿素a荧光的影响。维尔监测光合作用的亚致死变化，通过技术，如荧光，在响应金属胁迫，不仅表明损害光合机构和伴随的光合能力的变化，但也有减少碳同化，生长，生存和繁殖的后果。这种影响可能对红树林的个体和种群产生长期影响。研究结果表明，累积的锌在叶组织中的水平平均3倍低于沉积物金属浓度，这表明排除机制的积累。
The article cites a study on effects of Zinc (Zn) exposure on chlorophyll a fluorescence in the grey mangrove, Avicennia marina (Forsk.) Vierh. Monitoring sub-lethal changes in photosynthesis, via a technique such as fluorescence, in response to metal stress not only indicates damage to the photosynthetic apparatus and accompanying changes in photosynthetic capacity, but also has consequences for reduced carbon assimilation, growth, survival and reproduction. Such effects may have implications for mangrove individuals and populations in the long term. Results of the study revealed that accumulated Zn levels in leaf tissues were on average 3 times lower than sediment metal concentrations, suggesting an exclusion mechanism to accumulation.
