The aim of the study was to use a battery of biotests composed of producers (Selenastrum capricornutum, Sorghum saccharatum, Lepidium sativum, and Sinapis alba), consumers (Thamnocephalus platyurus), and decomposers (Tetrahymena thermophila) to evaluate the toxicity of snowmelt and winter storm water samples. The toxicity of the samples collected in the winter period December to February (2010-2011), in one of the largest agglomerations in Poland, the city of Lodz, was compared to that of storm water samples taken under similar conditions in June. The most toxic snowmelt samples were found to be high acute hazard (class IV), while the remaining samples were rated as slight acute hazard (class II). L. sativum (in the Phytotox test) was the most sensitive test organism, giving 27 % of all toxic responses, followed by S. capricornutum with 23 % of all responses. T. thermophila was the least sensitive, with only 2 % of all toxic responses. The greatest range of toxicity was demonstrated by samples from the single family house catchment: no acute hazard (class I) to high acute hazard (class IV).
本研究的目的是使用一组由生产者(羊角月牙藻、甜高粱、萝卜和白芥)、消费者(扁头褶胸鱼)和分解者(嗜热四膜虫)组成的生物测试来评估融雪水和冬季暴雨水样的毒性。将2010 - 2011年12月至2月冬季期间在波兰最大的聚居地之一罗兹市采集的水样的毒性与6月在类似条件下采集的暴雨水样的毒性进行了比较。发现毒性最大的融雪水样具有高急性危害(IV级),而其余水样被评为轻微急性危害(II级)。萝卜(在植物毒性测试中)是最敏感的测试生物,产生了所有毒性反应的27%,其次是羊角月牙藻,占所有反应的23%。嗜热四膜虫最不敏感,仅占所有毒性反应的2%。独栋房屋集水区的水样表现出最大的毒性范围:从无急性危害(I级)到高急性危害(IV级)。
