The increasing use of nanomaterials in academic and industrial environments has raised concerns about the potential effects of these materials on human and the environment. Researches have shown that occupational exposure to nanomaterials can affect employees' health. Many companies are active in the field of nanotechnology in Iran. Therefore, this study was designed and conducted to investigate the relationship between the symptoms of these companies' employees and exposure to nanomaterials.
The study was conducted among employees of 52 nanotechnology companies in Tehran. For this study, the employees of these companies were categorized in two groups: "exposed" and "non-exposed" to nanomaterials. Data collection tools included the NanoTool method form and a nonspecific symptom questionnaire designed and validated by a team of 19 experts in various fields. Finally, data were analyzed using SPSS.22 software.
The results showed that the frequency of cutaneous (such as roughness, itching and redness), respiratory (such as cough, sneezing, and burning throat) and ocular (such as burning, itching and redness) symptoms were higher among the exposed workers to nanomaterials. Examination of the correlation between these symptoms in the two studied groups showed that symptoms with high frequency have a significant relationship with exposure to nanomaterials.
Given the high prevalence of some symptoms among the employees of the studied companies and their association with exposure to nanomaterials, it seems necessary to take control measures to reduce the exposure of employees to nanomaterials and consequently reduce the Investigated symptoms.
纳米材料在学术和工业环境中的使用日益增加，引发了人们对这些材料对人类和环境潜在影响的担忧。研究表明，职业接触纳米材料会影响员工健康。伊朗有许多公司活跃于纳米技术领域。因此，本研究旨在调查这些公司员工的症状与纳米材料接触之间的关系。
该研究在德黑兰52家纳米技术公司的员工中进行。在本研究中，这些公司的员工被分为两组：纳米材料“暴露组”和“非暴露组”。数据收集工具包括纳米工具方法表格和由19位各领域专家组成的团队设计并验证的非特异性症状问卷。最后，使用SPSS.22软件对数据进行分析。
结果显示，纳米材料暴露组工人的皮肤症状（如粗糙、瘙痒和发红）、呼吸道症状（如咳嗽、打喷嚏和喉咙灼痛）和眼部症状（如灼痛、瘙痒和发红）的发生率更高。对两组研究对象中这些症状的相关性检查表明，高频率症状与纳米材料暴露有显著关系。
鉴于研究公司员工中某些症状的高发生率及其与纳米材料暴露的关联，似乎有必要采取控制措施，以减少员工接触纳米材料，从而减少所调查的症状。
