Gondek et al. (2018) investigate the mobility of heavy metals in sandy soil after application of composts produced from maize straw, sewage sludge and biochar. The authors made a little attention to role of the soil properties and soil condition on the metals chemical behavior. In different section of the paper, the authors reported that the content of the metals extracted with water or 1 M NHNO was changed compared to the control treatment affected by the mentioned biosolids. Nowadays, different researches have shown that the trace metals nature have an important role in determining their fate in presence of different treatments. In addition to, organic compounds entered to the soil due to biosolids applications have a duplicate role in trace metals mobility. Therefore, it is needed this facts are considered to interpret the measurements in the original paper. Also, whenever effects of different materials are studied on the metals mobility, the metals status in the plant tissues presents valuable information to the scientists and readers for carefully interpreting the measurements, which it is ignored by the authors.
冈德克等人（2018 年）研究了在施用由玉米秸秆、污水污泥和生物炭制成的堆肥后，沙质土壤中重金属的迁移情况。作者很少关注土壤性质和土壤条件对金属化学行为的作用。在论文的不同部分，作者报告说，与对照处理相比，受所述生物固体影响的水或 1 M NHNO 提取的金属含量发生了变化。如今，不同的研究表明，痕量金属的性质在确定它们在不同处理存在下的命运方面起着重要作用。此外，由于生物固体的应用而进入土壤的有机化合物在痕量金属迁移中具有双重作用。因此，需要考虑这些事实来解释原始论文中的测量结果。此外，每当研究不同材料对金属迁移的影响时，植物组织中金属的状态为科学家和读者提供了有价值的信息，以便他们仔细解释测量结果，而作者忽略了这一点。
