Anatomical changes observed in a mangrove plant, Avicenna marina, were studied with special reference to heavy metal pollution at Visakhapatnam Meghadrigedda creek area. The pollution in the region was very well reported to have been caused by the port activities and also by several major industries abutting the Meghadrigedda creek area. The concentrations of heavy metals, namely copper, chromium, cadmium, manganese, zinc, and lead, were determined using ICP-MS techniques. The heavy metal concentrations are more in sediments than in the native soils, whereas when focused on the role of mangroves, especially in Avicenna marina species, plants, exposed to higher concentrations, exhibited anatomical variations in the xylem of the stem and leaves also. The stem internal structure showed a xerophytic adaptation, with a thick cuticle, thick-walled cortex with an appearance as stone cells. The mainly noticeable characteristics are moist leaves, with expanded mesophyll area, thick cuticle with wax deposition shown on the epidermis. At lower concentrations, these changes did not exist. Bioconcentration factor (BCF) and translocation factor (TF) had been calculated to estimate the efficiency of a plant to accumulate heavy metals from sediment to its roots and translocate the heavy metals from its roots to its stems and leaves, in observed anatomical changes at higher concentrated area plants.

在红树植物，观察到的解剖结构变化 阿维森纳码头，进行了研究以在维萨卡帕特Meghadrigedda小溪区域特别提到的重金属污染。据报道，该地区的污染是由港口活动以及毗邻梅格哈德里格达河地区的几个主要工业造成的。使用ICP-MS技术测定重金属的浓度，即铜，铬，镉，锰，锌和铅。沉积物中的重金属浓度比本地土壤中的重金属浓度高，而当重点关注红树林的作用时，尤其是在 阿维森纳滨海地区 暴露于较高浓度下的物种，植物在茎和叶的木质部中也表现出解剖学变化。茎的内部结构表现为旱生适应性，表皮较厚，皮层较厚，外观呈石细胞状。主要的显着特征是潮湿的叶子，叶肉面积扩大，表皮上厚厚的表皮上有蜡沉积。在较低浓度下，这些变化不存在。已计算出生物浓缩因子（BCF）和转运因子（TF），以估计植物在较高的解剖学变化下从沉积物向根部积累重金属并将其从根部转移至茎和叶的效率。集中地区的植物。
