有毒金属和类金属，特别是来自人类活动的有毒金属和类金属，现在污染着我们星球的大部分地区。植物提取是一种经过验证的技术，具有减少金属/类金属污染的潜力，并且在经济上可行的情况下，回收有价值的金属（“植物采矿”）。为了实现这些目标，在过去二十年里，出版物激增。虽然正在取得重要进展，但不断传播的不良做法，以及由此产生的资金来源流失，阻碍了这一有前途的研究领域。这包括对超积累植物物种的错误认定、使用极高剂量水平的水培、滥用生物富集因子、使用低积累的粮食或生物质作物进行植物提取、“模板纸”现象，其中元素X的已知超积累植物与元素Y一起使用，或常见的杂草物种与任何种类的元素一起使用以使其“超积累”。在此，我们强调了这些误解，希望这将有助于：（i）传播植物金属积累的准确定义;（ii）通过限制不必要的出版物的膨胀来消除不良实践的传播-“模板论文”写作的实践;（iii）被期刊编辑和审稿人用来验证他们对作者的推理;以及（iv）有助于更快地向实地从业人员提供这一技术。
Toxic metals and metalloids, especially from anthropogenic sources, now pollute substantial areas of our planet. Phytoextraction is a proven technology with the potential to reduce metal/metalloid pollution, and where financially viable, recover valuable metals (‘phytomining’). Toward these aims, there has been a surge of publications over the last two decades. While important progress is being made, ongoing propagation of poor practice, and the resultant drain from funding sources, is hindering this promising research area. This includes mis-ascribing hyperaccumulator species, hydroponics with extremely high dose levels, misuse of Bioconcentration Factors, use of food or biomass crops with low accumulation for phytoextraction, the phenomenon of ‘template papers’ in which a known hyperaccumulator for elementXis dosed with elementY, or a common weed species dosed with any variety of elements to make it ‘hyperaccumulate’. Here we highlight these misconceptions with the hope that this will help to: (i) disseminate accurate definitions forin plantametal accumulation; (ii) quash the propagation of poor practice by limiting the inflation of unnecessary publicationsviathe practice of ‘template paper’ writing; (iii) be used by journal editors and reviewers to validate their reasoning to authors; and (iv) contribute to faster progress in delivering this technology to in-the-field practitioners.
