Abstract:An inductively coupled plasma mass spectrometer and an inductively coupled plasma emission spectrometer were used to measure the content of eight mineral elements（K,Na,Ca,Mg,Fe,Zn,Cu,and Mn） in pineapples and their cultivated soils from three towns in Qionghai City.Thermodynamic diagrams and principal component analysis were employed to analyze the distribution of mineral elements in the peel,flesh,and soil samples of pineapples produced in different towns and the correlations between the content difference of different mineral elements in pineapples and producing areas.Furthermore,the migration patterns of mineral elements were explored.The results showed strong correlations of K,Mg,Ca,Zn,and Cu between soil and peel,as well as strong correlations of Mg,Ca,Zn,Mn,and Cu between soil and flesh.Different mineral elements presented disparities in enrichment degree and distribution between the peel and the flesh,with varying migration coefficients.
