In the present study, the root chromosomal aberration assay was used to determine the genotoxic effects of copper and cadmium ions solutions before and after sorption processes. The sorption process was carried out using unmodified charcoal powder, nitrilotriacetic acid (NTA)-modified charcoal powder, and The frequency of total chromosomal aberrations was observed to be 24.30-45.13% for copper and 13.16-45.14% for cadmium at different concentrations (1-500 mg/l) before the sorption process. Both metal ions solutions resulted in significant reduction of chromosomal aberrations after all the modes of the sorption processes. However, the order of reduction of percentage chromosomal aberrations for copper and cadmium solutions was found to be 45.29-70.04% and 47.80-84.57%, respectively (NTA-modified charcoal powder); >44.53-54.32% and 37.10-79.40%, respectively (unmodified charcoal powder); >15.59-48.51% and 13.63-21.50%, respectively ().
在本研究中，采用根部染色体畸变试验来确定吸附过程前后铜离子和镉离子溶液的遗传毒性效应。吸附过程使用未改性的木炭粉、次氮基三乙酸（NTA）改性的木炭粉进行，在吸附过程前，不同浓度（1 - 500毫克/升）的铜溶液总染色体畸变频率为24.30 - 45.13%，镉溶液为13.16 - 45.14%。所有吸附方式处理后，两种金属离子溶液均导致染色体畸变显著减少。然而，发现铜溶液和镉溶液染色体畸变减少百分比的顺序分别为：45.29 - 70.04%和47.80 - 84.57%（NTA改性的木炭粉）；>44.53 - 54.32%和37.10 - 79.40%（未改性的木炭粉）；>15.59 - 48.51%和13.63 - 21.50%（）。 （原文此处括号内容缺失完整信息）
