Abstract

Heavy metals are the harmful elements, regarded as carcinogens. Nevertheless, owing to their physical and chemical properties, they are still used in the production of several commercial products. Utilization of such products increases the chance for the exposure of heavy metals, some of them are categorized as probable human carcinogens (Group 1) by the International Agency for Research on Cancer. Exposure of heavy metals to school children at early age can result severe life time health issues and high chance of emerging cancer. Thus, we have performed study relating to the presence of heavy metals in acrylic color paints commonly used by the school children. Acrylic paints of different colors were assayed for seven potential heavy metals manganese (Mn), cobalt (Co), nickel (Ni), zinc (Zn), arsenic (As), cadmium (Cd) and lead (Pb) using microwave digestion and iCAPQ inductively coupled plasma mass spectrometry (ICP-MS) system. The optimized method including paints digestion reagents nitric acid (HNO, 65%, 5 mL) and hydrofluoric acid (HF, 40%, 2 mL) have offered excellent method performance with recovery values ranged between 99.33% and 105.67%. The elements were identified in all of the analyzed samples with concentrations ranged from 0.05 to 372.59 µg/g. Cd constitutes the lower percentage (0.05%), whereas Zn constitutes high ratio contribution which was tremendously high (68.33%). Besides, the paints contamination was also color specific, with considerably total heavy metal concentrations found in brunt umber (526.57 µg/g) while scarlet color (12.62 µg/g) contained lower amounts. The outcomes of our investigation highlight the necessity for guidelines addressing the heavy metals in acrylic color paints intended for the school children usage.

摘要

重金属是有害元素,被认为是致癌物质。然而,由于它们的物理和化学性质,它们仍被用于生产几种商业产品。这些产品的使用增加了重金属暴露的机会,其中一些被国际癌症研究机构归类为可能的人类致癌物(第 1 组)。儿童在早期接触重金属可能会导致严重的终身健康问题和癌症高发的风险。因此,我们进行了一项关于学校儿童常用的丙烯颜料中重金属存在情况的研究。使用微波消解和 iCAPQ 电感耦合等离子体质谱(ICP-MS)系统,对不同颜色的丙烯颜料进行了七种潜在重金属(锰(Mn)、钴(Co)、镍(Ni)、锌(Zn)、砷(As)、镉(Cd)和铅(Pb))的测定。优化后的方法包括使用硝酸(HNO3,65%,5 毫升)和氢氟酸(HF,40%,2 毫升)消解油漆试剂,回收率在 99.33%至 105.67%之间,具有优异的方法性能。在所分析的所有样品中均检测到了这些元素,浓度范围为 0.05 至 372.59 µg/g。Cd 的比例最低(0.05%),而 Zn 的比例最高(68.33%)。此外,油漆污染也具有颜色特异性,棕土(526.57 µg/g)中发现的总重金属浓度明显较高,而猩红色(12.62 µg/g)中含量较低。我们的研究结果强调了制定针对学校儿童使用的丙烯颜料中重金属的指导方针的必要性。
