“…The method was also used to assess the maturity of composts (Jakubus 2012, Hase andKawamura 2014). Some authors point out the need for additional tests to investigate the effects of product contaminants on seedling growth (Obidoska and Hadam 2008) to get a complete picture of the toxic effects of the tested products.…”

To test the potential harmfulness of soils fertilized with sludge-based products to plant organisms, a biotest method using the physiological/biochemical reaction of the organisms to assess their toxicity was chosen. This paper presents the results of a preliminary ecotoxicological study of different products: a sludge-based fertilizer, a plant growth promoter, and a reclamation blend. The study was conducted using Sinapis alba L., a plant used in agriculture for intercropping and recommended for toxicological testing. Toxicity tests were performed in a gradient of concentrations of the indicated products (2.5%, 5%, and 10%). For comparison purposes, a trial containing a commercial fertilizer was used alongside the control soil (without additives). The fertilizer and the crop support agent were of low toxicity, but data analysis indicated toxicity of the so-called reclamation blend, which contained heavy metals among other things. The test products showed an increase in toxicity with the increasing dose used. This research represents an important step in assessing the usefulness of products created from sewage sludge and may help overcome the "psychological barrier" that prevents potential investors from investing capital that would allow production to spread.

In this study, we examined the fate and future of sewage irrigation fields; historic urban wetlands that served as sewer drainage before modern sewage treatment plants were built. Our aim in this study was to reappraise sewage irrigation fields in the urban fabric of modern cities and to analyse the possibility of re-integrating them into the ecosystem services system, as well as into green and blue infrastructure, providing leisure and recreational opportunities, stabilising the city’s biodiversity and microclimate, and increasing water retention in these areas. The research was based on the identification of the location of sewage irrigation fields in green and blue infrastructure systems, determination of the scale and extent of their connections to the urban fabric and an analysis of their multi-functionality including: ecological, climatic, hydrological, landscape, spatial, environmental, cultural and social, educational, and tourist and recreational functions.
