The growing population generates a lot of waste, including industrial waste. These wastes can be used as sorbents, for example in the form of aggregates, which have a porous structure and the ability to absorb pollutants. The use of natural sorbents, which are characterised by low toxicity and biodegradability, is in line with the idea of sustainable development. In ecotoxicological studies, the effects of calcium and magnesium sorbent extracts on two plant species A. sativa L. and L. sativum, and earthworms E. andrei, were evaluated in acute toxicity tests. The conclusions of the studies indicate that calcium and magnesium sorbents do not pose a threat to the organisms tested with a short exposure time, which allows their use in industry and environmental protection. Further research on natural sorbents is recommended, as it is necessary to understand the long-term effects of these sorbents. Their effects may also depend on the specific environment conditions in which they are used, suggesting the need for further research on the effects of sorbents on organisms under different conditions, such as in soil, and the use of other test organisms.
