Abstract

This paper examines the impact of heavy toxic metals on human health. It has been shown that the long-term accumulation of heavy metals in the body can lead to a slowdown in the development of physical, muscle and neurological degenerative processes that mimic certain diseases, such as Parkinson’s disease and Alzheimer’s disease. The transfer of heavy metals from ecosystem to human is also analyzed. It is noted that some heavy metals generate free radicals, which can lead to oxidative stress and cause other cellular damage, a carcinogenic effect, affecting a number of proteins. As a result of the measurement of mass concentrations of zinc, cadmium, lead and copper by inversion voltammetry after preliminary preparation of samples by wet mineralization, it was found that the content of concentrations of Zn, Cd, Pb, Cu in tea flashes was 3.50 ± 1.40 mg/kg, 0.03 ± 0.038 mg/kg, 0.370 ± 0.130 mg/kg, 3.20 ± 1.10 mg/kg, respectively Low Zn and Cd 0.56 ± 0.22 mg/kg and 0,0012 ± 0,0048 mg/kg, respectively, were found in fresh tomatoes, and Pb and Cu 0,013 ± 0,0045 mg/kg and 0.57 ± 0.21 mg/kg, were found in fresh cucumbers respectively. The content of mass concentrations of toxic metals Cd, Pb in all analysed samples of tea leaves and vegetables (tomatoes and cucumbers) is less than their permissible levels specified in regulatory documents in force in the Republic of Azerbaijan.
阿塞拜疆共和国兰卡兰-阿斯塔拉地区种植的茶叶片和蔬菜中重金属对人体健康的影响及其含量测定方法
本文探讨了重金属对人体健康的影响。研究表明,重金属在体内的长期积累会导致身体、肌肉和神经退化过程的发展放缓,这些退化过程类似于某些疾病,如帕金森病和阿尔茨海默病。分析了重金属从生态系统向人体的转移。值得注意的是,一些重金属会产生自由基,这会导致氧化应激并引起其他细胞损伤,具有致癌作用,影响许多蛋白质。由于质量的测量浓度的锌、镉、铅和铜的反演伏安法初步制备样品的湿化后,发现锌浓度的内容,Cd,铅、铜在茶闪光为3.50±1.40毫克/公斤,0.03±0.038毫克/公斤,0.370±0.130毫克/公斤,3.20±1.10毫克/公斤,分别低锌和Cd 0.56±0.22毫克/公斤,0,0012±0,0048毫克/公斤,分别被发现在新鲜的西红柿,新鲜黄瓜中Pb和Cu含量分别为0.013±0.0045 mg/kg和0.57±0.21 mg/kg。在所有经分析的茶叶和蔬菜(西红柿和黄瓜)样本中,有毒金属Cd、Pb的质量浓度低于阿塞拜疆共和国现行监管文件所规定的容许水平。
