Abstract

Biochar derived from the pyrolysis of biomass is recognized for its carbon sequestration capacity. By adding physical or chemical activation steps, its properties can be enhanced, resulting in activated or modified biochar. However, investigating the possible toxic effects for safer application is necessary. In this study, we aimed to assess the ecotoxicological effects of extracts from biochars prepared from sugarcane bagasse activated with zinc chloride and heat treated at temperatures ranging from 300 to 1000 °C. Using Artemia salina as an indicator of toxicity, we observed variation in mortality ranging from 27.5 % to 100 % as the temperature varied between 1000 and 300 °C. The leachate from the sample prepared at 300 °C, which had the highest zinc content, presented an LC50 of 0.53 w/v. Phytotoxicity tests with Lactuca sativa revealed that extracts from biochars prepared at lower temperatures presented greater phytotoxicity, with reductions in relative germination, relative average radicle growth and the germination index. These results highlight the need to assess the ecotoxicological risks of activated biochar with zinc chloride. The sensitivities of Artemia salina and Lactuca sativa are promising for detecting these effects, suggesting that they are effective approaches for assessing environmental safety. These findings not only broaden our understanding of the adverse effects of activated biochar but also guide safe and sustainable practices for its future application.
用氯化锌活化甘蔗渣生物秸秆提取物的生态毒性评估
生物质热解产生的生物炭具有公认的固碳能力。通过添加物理或化学活化步骤,可以增强其特性,从而产生活化或改性生物炭。然而,为了更安全地应用生物炭,有必要对其可能产生的毒性影响进行调查。在这项研究中,我们旨在评估从甘蔗渣制备的生物炭中提取的提取物的生态毒理学效应,这些生物炭是用氯化锌活化并在 300 至 1000 °C 的温度下进行热处理而制备的。我们用鳀鱼作为毒性指标,观察到温度在 1000 ℃ 和 300 ℃ 之间变化时,死亡率从 27.5 % 到 100 % 不等。在 300 °C 下制备的样品浸出液锌含量最高,半数致死浓度为 0.53 w/v。用莴苣(Lactuca sativa)进行的植物毒性测试表明,在较低温度下制备的生物炭萃取物具有更强的植物毒性,相对发芽率、相对平均胚根生长率和发芽指数都有所下降。这些结果突出表明,有必要对氯化锌活化生物炭的生态毒理学风险进行评估。在检测这些效应方面,盐水蒿和莴苣的灵敏度很高,这表明它们是评估环境安全性的有效方法。这些发现不仅拓宽了我们对活性生物炭不利影响的认识,还为今后安全、可持续地应用生物炭提供了指导。
