Heavy metal pollution has become one of the most threats that can endanger human health due to accumulation and consumption of fruits. Our study was aimed to evaluate physicochemical quality parameters, level of heavy metals, and assessment of health risks of lead (Pb), Manganes (Mn), zinc (Zn), iron (Fe), copper (Cu), chromium (Cr), and cadmium (Cd) in mango fruits from Arba Minch, Wolaita Sodo, and Damote Gale study areas. Quality parameters such as, total soluble solid, moisture, ash, titratable acidity, pH, total sugar, reducing sugar and non-reducing sugar, fat and fiber content of mango fruit were ranged between 15.68° and 18.92°B, 81.080-84.320 %,g, 4.040-4.080, 11.56-12.95%, 10.07-12.54%, 1.60-3.83%,0.397-0.673%, and 1.338-2.375% 0.283-1.030 %, 0.311-0.366 mg/100 g, 4.040-4.080, 11.56-12.95 %, 10.07-12.54 %, 1.60-3.83 %,0.397-0.673 %, and 1.338-2.375 % respectively. The average levels of metals in mango fruits were in the range Fe (1.166-1.486 mg/kg), Cu (0.019-0.198 mg/kg), Mn (0.121-0.239 mg/kg), Zn (0.134-0.321 mg/k), Pb (0.035-0.097 mg /kg) and Cd (0.193 mg/kg). Chromium is not detected in our study, because its level is below the detection limit. On average within metals, the highest level was obtained in Fe in the range 1.166-1.486 mg/kg, whereas the minimum level was determined in Pb from 0.035 to 0.097 mg/kg. The EDI values of accumulated elements in mango fruits follows the increasing order as; Fe Zn > Mn > Cu > Cd > Pb. Except Damot Gale sample in moderate range, the values of total carcinogenic risks (TCR) in all metals were less than 1 × 10, which is considered to be safe. All THQ and HI values were 1, which indicates that the accumulated metals did not contribute risk for human health. The present study clearly indicated that the consumption of mango fruits in the studied areas does not pose any health hazard associated with any of the selected heavy metals.
由于水果的积累和消费，重金属污染已成为危害人类健康的最大威胁之一。我们的研究旨在评估来自阿尔巴明奇、沃莱塔索多和达莫特加勒研究地区的芒果果实的理化质量参数、重金属含量，并评估铅（Pb）、锰（Mn）、锌（Zn）、铁（Fe）、铜（Cu）、铬（Cr）和镉（Cd）的健康风险。芒果果实的质量参数，如总可溶性固形物、水分、灰分、可滴定酸度、pH值、总糖、还原糖和非还原糖、脂肪和纤维含量分别在15.68°至18.92°B、81.080 - 84.320%、4.040 - 4.080、11.56 - 12.95%、10.07 - 12.54%、1.60 - 3.83%、0.397 - 0.673%、1.338 - 2.375%、0.283 - 1.030%、0.311 - 0.366毫克/100克、4.040 - 4.080、11.56 - 12.95%、10.07 - 12.54%、1.60 - 3.83%、0.397 - 0.673%和1.338 - 2.375%之间。芒果果实中金属的平均含量范围为铁（1.166 - 1.486毫克/千克）、铜（0.019 - 0.198毫克/千克）、锰（0.121 - 0.239毫克/千克）、锌（0.134 - 0.321毫克/千克）、铅（0.035 - 0.097毫克/千克）和镉（0.193毫克/千克）。在我们的研究中未检测到铬，因为其含量低于检测限。在金属中，平均而言，铁的含量最高，范围为1.166 - 1.486毫克/千克，而铅的含量最低，为0.035至0.097毫克/千克。芒果果实中累积元素的EDI值按以下递增顺序排列：铁＞锌＞锰＞铜＞镉＞铅。除了处于中等范围的达莫特加勒样本外，所有金属的总致癌风险（TCR）值均小于1×10，这被认为是安全的。所有THQ和HI值均≤1，这表明累积的金属不会对人类健康造成风险。本研究清楚地表明，研究地区的芒果果实消费不会对与任何选定重金属相关的健康造成危害。
