The level of pollution and the variability of rainwater runoff quality collected in reservoirs next to the new Lublin bypass (south-eastern Poland) were assessed in this scientific paper. In the rainwater harvesting and treatment system, two types of reservoirs with different construction, size and presence of pre-treatment devices were used. Laboratory tests involved selected physical, oxygen, biogenic, salinity indicators, heavy metals and polycyclic aromatic hydrocarbons. Particularly large variability in concentrations included NO₂^-, TP, PO₄^3-, K⁺ and Cl^-. Parameters decreasing the water quality were mainly conductivity, BOD₅, COD, NO₂^-, TP and Cl^-. High concentrations of salt and phosphorus in collected rainwater require great care in final management (risk of salinization and eutrophication). In the second year of research, there was significant deterioration of water quality, which may result from different weather conditions and gradual accumulation of pollutants in new reservoirs. Not many significant differences were found in the quality of water collected in reservoirs with pre-treatment and without it. Loads of heavy metals and aromatic hydrocarbons in reservoirs were relatively small. However, these impurities have high durability and the ability to accumulate in the environment. Therefore, further studies should also take into account monitoring of bottom sediments and areas adjacent to the bypass.

在这篇科学论文中，我们评估了在新的卢布林旁路（波兰东南部）旁的水库中收集到的污染水平和雨水径流质量的变异性。在雨水收集和处理系统中，使用了两种类型的水库，它们具有不同的结构，大小和预处理装置。实验室测试涉及选定的物理，氧气，生物成因，盐度指标，重金属和多环芳烃。特别是在大的浓度变化包括NO ₂ ^-，TP，PO ₄ ^3-，K ⁺和Cl ^- 。参数降低水质主要是导电性，BOD ₅，COD，NO ₂ ^-，TP和Cl ^- 。收集的雨水中高浓度的盐和磷需要在最终管理（盐碱化和富营养化的风险）中格外小心。在第二年的研究中，水质显着恶化，这可能是由于不同的天气条件和新的水库中污染物逐渐积累造成的。在没有进行预处理的情况下，在水库中收集的水质没有发现很多显着差异。油藏中重金属和芳烃的负荷相对较小。但是，这些杂质具有高耐久性和在环境中累积的能力。因此，进一步的研究也应考虑对底部沉积物和旁路附近区域的监测。
