The relationship between metal levels in the Olt River ecosystem in southern Romania (measured during 2018‒2019, with 1064 sediment and water samples) and daily climate data were explored to assess the need for targeted source identification and mitigation strategies. In 2018, there was a strong relationship between the sediment Pb, As, Cd, and Hg contents and temperature (r > 0.8, p < 0.001). Mercury in sediments had a positive correlation with precipitation, and Hg in the water correlated with minimum temperature in May 2018 (p < 0.01). In July 2019, heavy metals were positively correlated with precipitation and negatively correlated with temperature. According to nonsymmetrical correspondence analysis, the four climate parameters analyzed were linearly correlated with the frequency of metal detection (p < 0.001) in both years. The statistical analysis showed strong relationships between heavy metal levels and climatic factors and attributed the discrepancies in elemental concentrations between 2018 and 2019 to climate warming.

探索了罗马尼亚南部奥尔特河生态系统中金属水平（在 2018-2019 年期间测量，使用 1064 个沉积物和水样）与每日气候数据之间的关系，以评估对有针对性的来源识别和缓解策略的需求。2018年沉积物Pb、As、Cd、Hg含量与温度存在较强的相关性（r  >0.8，p  <0.001）。沉积物中的汞与降水呈正相关，水中的汞与 2018 年 5 月的最低温度相关（p < 0.01)。2019年7月，重金属与降水呈正相关，与气温呈负相关。根据非对称对应分析，所分析的四个气候参数与两年的金属检测频率呈线性相关（p  < 0.001）。统计分析表明，重金属水平与气候因素之间存在密切关系，并将 2018 年至 2019 年之间元素浓度的差异归因于气候变暖。
