中文摘要：本文以罗马尼亚市售草莓为研究样本，检测草莓中农药、微量元素浓度以及H-2/H-1、O-18/O-16和 C-13/C-12稳定同位素比率。检测结果显示，17个草莓检测样本中，只有一个样本中检测到异菌脲杀菌剂残留（8.6μg/kg）；除了锰和钙元素浓度不相关外，其他元素浓度之间呈正相关，主成分分析结果表明，四种主要成分所占比例达到81.990%。
外文摘要：This study was conducted on strawberries sold on Romanian markets, and its scope was to illustrate the pesticide and elemental concentrations. To emphasize these differences, the stable isotopic ratios of H-2/H-1, O-18/O-16, and C-13/C-12 were also determined. A total of 17 samples were analyzed; only one included a measurable concentration of the fungicide iprodione (8.6 mu g/kg). Pearson correlation results established only positive correlation between elemental concentrations. Only manganese and calcium were uncorrelated. Principal component analysis extracted four principal components, explaining a total variance of 81.990%. Every parameter was loaded by specific elements.
