Abstract

Scalp hair samples of traffic police officers were analyzed for 11 selected metals. The concentration of Pb and Co in the hair of traffic police officers in the city center had significant differences with other areas (p < 0.05). Also, the concentration of Al, Zn, and Cu in the hair of police officers in the south of Tehran was mainly different from other regions (p < 0.05). In this study, the concentrations of all studied elements were lower in traffic police officers who used masks and a considerable difference was observed between the concentrations of Co, Cu, Pb and Cd between the two groups (p < 0.05). In this study, a significant positive relationship was found between fish consumption and Cd concentration (r = 0.310; p < 0.01). A negative correlation was found between the intake of fruits and the levels of heavy metals Co, Zn, and As in hair. This study also found a negative correlation between BMI and hair concentrations of Cu, Zn, Cr, and Fe (r = −0.78, p > 0.02; r = −0.70, p > 0.05; r = −0.64, p > 0.05; r = −0.63, p > 0.05 respectively) in individuals classified as underweight (BMI ≤18.49 kg/m², n = 8).

伊朗德黑兰交通警察头发中有毒金属暴露因素的调查。

对交通警察的头皮头发样本进行了11种选定的金属分析。中心城区交警头发Pb、Co浓度与其他地区差异有统计学意义（p < 0.05）。此外，德黑兰南部警察头发中Al、Zn、Cu的浓度与其他地区差异较大（p < 0.05）。在本研究中，戴口罩的交警体内各元素的浓度均较低，Co、Cu、Pb、Cd的浓度在两组间有显著差异（p < 0.05）。在本研究中，鱼类食用量与Cd浓度呈显著正相关(r = 0.310；P < 0.01)。研究发现，水果摄入量与头发中Co、Zn、As等重金属含量呈负相关。本研究还发现BMI与头发中Cu、Zn、Cr和Fe的浓度呈负相关(r = -0.78, p < 0 0.02；R = -0.70, p < 0.05；R = -0.64, p < 0.05；r = -0.63, p < 0.05)，体重过轻个体（BMI≤18.49 kg/m2, n = 8）。

期刊介绍： Food and Chemical Toxicology (FCT), an internationally renowned journal, that publishes original research articles and reviews on toxic effects, in animals and humans, of natural or synthetic chemicals occurring in the human environment with particular emphasis on food, drugs, and chemicals, including agricultural and industrial safety, and consumer product safety. Areas such as safety evaluation of novel foods and ingredients, biotechnologically-derived products, and nanomaterials are included in the scope of the journal. FCT also encourages submission of papers on inter-relationships between nutrition and toxicology and on in vitro techniques, particularly those fostering the 3 Rs. The principal aim of the journal is to publish high impact, scholarly work and to serve as a multidisciplinary forum for research in toxicology. Papers submitted will be judged on the basis of scientific originality and contribution to the field, quality and subject matter. Studies should address at least one of the following: -Adverse physiological/biochemical, or pathological changes induced by specific defined substances -New techniques for assessing potential toxicity, including molecular biology -Mechanisms underlying toxic phenomena -Toxicological examinations of specific chemicals or consumer products, both those showing adverse effects and those demonstrating safety, that meet current standards of scientific acceptability. Authors must clearly and briefly identify what novel toxic effect (s) or toxic mechanism (s) of the chemical are being reported and what their significance is in the abstract. Furthermore, sufficient doses should be included in order to provide information on NOAEL/LOAEL values.
