The quality of urban snow was studied with regard to how the concentrations of selected metals and phosphorus vary over time. The area studied is situated in northern Sweden (65 degrees 36' N; 22 degrees 13' E). Snow samples were taken at three different locations in the city centre, approximately every second week, throughout winter. This study has clearly shown the importance of local conditions and snow clearance operations on snow quality. The study also shows that it is difficult to interpret and predict the concentrations of lead, zinc, copper and phosphorus in the snow. However, it should be possible to predict the mass loads of these substances from the deposition velocities, if the snow handling methods and routines, as well as the local circumstances are known.
针对特定金属和磷的浓度随时间变化的情况，对城市积雪质量进行了研究。研究区域位于瑞典北部（北纬65度36分；东经22度13分）。整个冬季，大约每隔一周就在市中心的三个不同地点采集雪样。这项研究清楚地表明了当地条件和积雪清除作业对雪质量的重要性。该研究还表明，很难解释和预测雪中铅、锌、铜和磷的浓度。然而，如果已知积雪处理方法和流程以及当地情况，就应该能够根据沉积速度预测这些物质的质量负荷。
