Bruguiera gymnorhiza, an evergreen mangrove tree, is tolerant of bisphenol A (BPA) and has potential BPA removal capability. BPA is highly toxic to plants at high concentrations, wherein they exhibit damaged symptoms such as chlorosis, necrosis, and wilting. The LD50 of BPA toxicity for this plant was statistically estimated to be 39.97 mg L(-1). B. gymnorhiza can reduce COD from 15408 +/- 246 to 49 +/- 30 mg L(-1) by (approximately 99% reduction of the initial value) and can reduce content to levels below the industrial effluent standard of Thailand (<120 mg L(-1)) within 48 days. This plant can completely remove BPA from the solution within 51 days of treatment. Polysaccharides and organic acids were found in the solution and were caused by plant response to the toxicity of BPA. In addition, B. gymnorrhiza can also reduce total dissolved solids (TDS) and salinity in real wastewater. Therefore, B. gymnorrhiza has potential for removal of BPA and TDS in contaminated in wastewater.
木榄，一种常绿红树林植物，对双酚 A（BPA）具有耐受性，并具有潜在的 BPA 去除能力。高浓度的 BPA 对植物具有高度毒性，它们表现出叶片失绿、坏死和萎蔫等损伤症状。该植物的 BPA 毒性 LD50 经统计估计为 39.97 毫克/升。木榄可以将 COD 从 15408 +/- 246 降至 49 +/- 30 毫克/升（初始值降低约 99%），并在 48 天内将含量降低到泰国工业废水标准以下（<120 毫克/升）。该植物在 51 天的处理时间内可以将 BPA 从溶液中完全去除。在溶液中发现了多糖和有机酸，这是植物对 BPA 毒性的反应所致。此外，木榄还可以降低实际废水中的总溶解固体（TDS）和盐度。因此，木榄具有去除受污染废水中 BPA 和 TDS 的潜力。
