Mangroves are a group of plants growing in estuarine region. These species survive well in saline environment with some adaptations in them. The members of family Avicenniaceae and Sonneratiaceae are of accumulating in nature and may bio-accumulate the pollutants from sediments and water. In order to improve the comprehensive understanding of heavy metal tolerance, the sediments and plant material (leaves) of mangroves were analyzed for heavy metals concentration from different creeks and estuaries of Maharashtra coast using atomic absorption spectrophotometer. The mangrove sediments were analyzed for indices such as enrichment factor, pollution load index, geo-accumulation index etc. to understand the level of pollutants. The bioaccumulation factor was also estimated to understand the bioaccumulation potential mangrove species i.e. Avicennia marina and Sonneratia apetala. The former species is commonly known as pollution tolerate, while the latter is pioneer in mangrove succession. The objectives of the study were to understand the potential of S. apetala in phytoremediation of heavy metals from both sediments and waste water. The mangrove sites like Kandalwada and Uran are on the borderline of pollution and needs proper protection and management.

使用统计指标评估印度马哈拉施特拉邦沿海红树林的生物富集潜力

红树林是在河口地区生长的一组植物。这些物种在盐环境中可以很好地生存，并且在其中具有一定的适应性。Avicenniaceae科和Sonneratiaceae科的成员在自然界中不断积聚，并可能从沉积物和水中生物积聚污染物。为了增进对重金属耐受性的全面了解，使用原子吸收分光光度计对红树林的沉积物和植物材料（叶片）进行了分析，分析了马哈拉施特拉邦沿河和不同河口的重金属含量。分析了红树林沉积物的富集系数，污染负荷指数，地积累指数等指标，以了解污染物的水平。还估计了生物积累因子以了解潜在的红树林物种的积累，即Avicennia码头和Sonneratia apetala。前者通常被认为是耐污染的，而后者是红树林演替的先驱。该研究的目的是了解S. apetala在植物修复沉积物和废水中的重金属方面的潜力。像坎达瓦达和乌兰这样的红树林地带正处于污染的边缘，需要适当的保护和管理。
