There is growing awareness in cities all over the world that blue-green infrastructure (BGI) can offer a wide range of ecosystem services that support a healthy urban environment. Green areas, including meadows and river valleys within cities, are useful for short-term water storage. This possibility has become more visible in recent years, as water management is increasingly combined with ecological objectives. However, the potential benefits arising from blue-green infrastructure are most likely only partially exploited due to the lack of a practical understanding of what these benefits are and how best to implement BGI. Therefore, there is a need to translate scientific knowledge of the functionality of BGI into principles for designing the new concept of resilience cities. Another important aspect of the approach to contemporary urban systems is the ‘circular economy’. Sponge City as an element of water-sensitive urban design (WSUD) protects local communities against excessive rainwater runoff and at the same time provides new green jobs. In hydrological terms, large impermeable surfaces contribute to surface runoff, which can lead to soil erosion, deterioration in water quality, the risk of flooding and drought.

The paper presents a study leading to a new acute toxicity test on embryonic and juvenile organisms of the great pond snail (Lymnaea stagnalis Linnaeus). Sulfuric acid, nitric acid, and ammonium hydroxide were used as waterborne toxicants in laboratory experiments. The exposure time was 24 h. Tests were conducted in 5–10 replications for each toxicant. The toxicity of the substances was classified according to different scales and the test’s sensitivity was compared to that of the commonly used bioindicator Daphnia magna Straus. The assessment of toxicity impact was supported by microscopic observations. The probit method was used as a parametric statistical procedure to estimate LC50 and the associated 95% confidence interval. Our study showed that the early developmental stages of Lymnaea stagnalis are very sensitive bioindicators, making it possible to detect even very low levels of the above-mentioned water toxicants. The highest toxicity is shown by ammonium hydroxide with LC50/24h values, respectively, 24.27 for embryos and 24.72 for juvenile forms, and the lowest is shown by nitric acid ions with LC50/24h values, respectively, 105.19 for embryos and 170.47 for juvenile forms. It is highly cost-effective due to simple and efficient breeding and the small size of the organisms in the bioassay population. Compared with Daphnia magna, relatively low concentrations of toxicants caused a lethal effect on embryonic and juvenile organisms of the great pond snail. Owing to their common occurrence and sensitivity, early developmental forms of Lymnaea stagnalis can be a valuable new tool in biomonitoring of the freshwater environment.
