摘要

摘要。本研究的目的是使用微波等离子体原子发射光谱法测定埃塞俄比亚种植的南瓜皮、果肉和种子中主要（Na、Mg、K、Ca）和重（Cr、Mn、Fe、Ni、Cu、Zn、Cd）金属的含量，并对其健康风险进行评估。干燥的粉末状样品（0.5g）在微波消化器中用69%的HNO3和30%的H2O2湿消化。南瓜样品的三个部分的回收率为90-110%。南瓜皮、果肉和种子样品中金属的平均浓度分别为K（27806±976729531±245210667±1133），Ca（5267±20923190±9002919±397），Mg（4716±469848±3494668±413），Fe（158±29111±46225±56），Na（167±11663.1±15171±123），Mn（28.9±1.49.61±3.233.4±4.9），Zn（24.2±4.410.6±4.067.5±12.3），Cu（8.14±1.1、15.1±9.3、10.8±0.9），Ni（3.79±2.4、2.14±1.3、3.44±2.8）、Cr（0.28±0.1、0.36±0.2、0.69±0.1）、Cd（0.24±0.1，0.46±0.1、1.39±0.2）mg/kg。南瓜果肉和种子的危害指数（HI）表明摄入南瓜是安全的，没有致癌风险。三个采样点通过CR和Cd摄入南瓜肉和南瓜籽导致的癌症总风险（CR）在1.1 x 10-4-1.8 x 10-4范围内，表明食用采样区种植的南瓜不会导致患癌症的风险。关键词：南瓜，矿物质含量，健康风险，微波等离子体原子发射光谱法。化学。Soc.Ethiop。2023，37（3），533-551.DOI:https://dx.doi.org/10.4314/bcse.v37i3.1

Major and heavy metals contents and health risk assessment of pumpkin peel, flesh and seed by microwave plasma-atomic emission spectroscopy

ABSTRACT. The aim of this study was to determine the levels of major (Na, Mg, K, Ca) and heavy (Cr, Mn, Fe, Ni, Cu, Zn, Cd) metals and health risk assessment of the peel, flesh and seed of pumpkins cultivated in Ethiopia, using microwave plasma-atomic emission spectrometry. Dried powdered samples (0.5 g) were wet digested with 69% HNO3 and 30% H2O2 in microwave digester. The percent recovery for the three parts of pumpkin samples were 90-110%. The mean concentration of metals in pumpkin peel, flesh, seed samples, respectively, were K (27806±9767, 29531±2452, 10667±1133), Ca (5267±2092, 3190±900, 2919±397), Mg (4716±469, 848±349, 4668±413), Fe (158±29, 111±46, 225±56), Na (167±116, 63.1±15, 171±123), Mn (28.9±1.4, 9.61±3.2, 33.4±4.9), Zn (24.2±4.4, 10.6±4.0, 67.5±12.3), Cu (8.14±1.1, 15.1±9.3, 10.8±0.9), Ni (3.79±2.4, 2.14±1.3, 3.44±2.8), Cr (0.28±0.1, 0.36±0.2, 0.69±0.1), Cd (0.24±0.1, 0.46±0.1, 1.39±0.2) mg/kg. The hazard index (HI) of pumpkin flesh and seed indicated ingestion of pumpkin is safe from non-carcinogenic risk. The total cancer risk (CR) due to consumption of pumpkin flesh and seed through Cr and Cd from the three sampling sites are in the range 1.1 x 10-4 -1.8 x 10-4, indicating a non-risk of exposure to cancer due to the consumption of pumpkin grown in the sampling areas.
