This paper presents data on the bioconcentration of heavy metals found in 10 plant species that occur in mangroves and inland ecosystems of India. The average concentration of mercury in the mangrove plants (0.068 microg g(-1)) was 11.3 times that of the inland plants (0.006 microg g(-1); p<0.05). The average concentration of lead in the mangrove plants (19.23 microg g(-1)) was 1.7 times that of the inland plants (11.38 microg g(-1); p<0.05). The mean bioconcentration factors for lead in mangrove plants (2.40 +/- 0.75) were higher than that the inland plants (1.42 +/- 0.15). The factor analysis accounted for 21.55% of the total variance showed accumulation of mercury and lead confirming the polluted nature.
本文呈现了在印度红树林和内陆生态系统中出现的10种植物体内重金属生物富集的数据。红树林植物中汞的平均浓度（0.068微克/克）是内陆植物（0.006微克/克；p<0.05）的11.3倍。红树林植物中铅的平均浓度（19.23微克/克）是内陆植物（11.38微克/克；p<0.05）的1.7倍。红树林植物中铅的平均生物富集系数（2.40±0.75）高于内陆植物（1.42±0.15）。因子分析解释了总方差的21.55%，显示汞和铅的积累证实了污染性质。
