Abstract: 【Objective】A study of detection and dietary exposure assessment of main mineral element contents of 4 dominant fruits from Liaoning province (including apple, pear, grape and peach) was carried out for the purpose of providing references to fruit production and consumptions. 【Method】 A total of 140 samples of the 4 fruits were collected from the main producing areas，including Dalian, Anshan, Yingkou, Jinzhou, Chaoyang, Huludao and Suizhong. The contents of 10 mineral elements were detected by ICP-AES and the correlation was analyzed by SPSS17.0 statistic software. Daily intake assessments of mineral elements from the 4 fruits among different populations were conducted and analyzed using recommended nutrient intake (RNI) or adequate intake (AI) and tolerable upper intake level (UL), respectively. Total diet risk assessment for adult was analyzed with residents balanced diet pagoda and food composition table. 【Result】 The average contents of 10 mineral elements were followed by the order of K (367.68 mg·kg^-1)＞P (122.65 mg·kg^-1)＞Mg (78.93 mg·kg^-1)＞Ca（76.36 mg·kg^-1）＞Na（12.37 mg·kg^-1）＞B（3.03 mg·kg^-1）＞Fe（2.86 mg·kg^-1）＞Cu（1.17 mg·kg^-1）＞Mn（1.02 mg·kg^-1）＞Zn（0.82 mg·kg^-1）and the range of coefficient of variation was from 27.80%（Mg）to 82.05%（Cu）. There was a significant correlation between K and Mg. Along with the growth of the age, the ratios of K to its AI was declined while other elements were showed down-up-down. The maximal ratio of Fe was 6.54% found in 4-7 ages and other elements were in 2-4 ages. In which, the percentages of RNI of Cu, Mg, P, K, Zn, Ca and Na were 83.30%, 11.01%, 8.57%, 8.43%, 4.25%, 2.46% and 0.39%, respectively. Results of dietary risk assessment showed that the average and the highest risk index of Cu in 2-4 ages were 12.50% and 37.02%, respectively. The risk indexes of other mineral elements were all far below 100% with the range of 0.33%（Zn）-13.40%（Mn）. Risk indexes of total diet for adults were followed by Mn（53.82%）＞Fe（49.93%）＞P（46.27%）＞Ca（35.23%）＞Zn（33.50%）＞Cu（28.61%）calculated by UL, which were all below 100%. 【Conclusion】 Contents of K, P, Mg and Ca were always higher than other trace elements in fruits. Synergistic effect plays a key role among different elements. Intake of 10 mineral elements from the above 4 fruits are safe to human health. The risk index of Cu is higher than other elements and should be paid a special attention. The daily dietary intakes of 10 mineral elements from total diet will not pose a health risk to adults.
