Effects of multiple pollutants including heavy metal on oxidative stress indices were measured in leaves and roots of Avicennia alba Blume. collected from three coastal locations in Kerala-Cochin, Kollam and Chetua. We observed significant activities in lipid peroxidation, root oxidizability, electrolyte leakage and antioxidant enzymes. Conversely, ascorbate and reduced glutathione showed low levels suggesting that these may be serving as a biomarker of heavy metals for monitoring pollution.
本研究在喀拉拉邦的三个沿海地区（高知、科钦和切图阿）采集了白骨壤的叶片和根系，检测了包括重金属在内的多种污染物对其氧化应激指标的影响。结果表明，在叶片和根系中，脂质过氧化作用、根氧化能力、电解质渗透率和抗氧化酶均呈现显著的活性，而抗坏血酸和还原型谷胱甘肽的含量则较低，这表明它们可能是重金属污染监测的生物标志物。
