Abstract

The paint and cattle slaughter industries have drawn attention to reuse practices due to the amount of wastewater generated. Furthermore, the effluent from the cattle slaughtering industry has a high nutrient load, just as the effluent from the paint industry has a high level of carbonate, a chemical species important for soil fertility and pH adjustment. Therefore, the combined use of these effluents can be a viable alternative for producing water with physical-chemical and microbiological characteristics useful for the agricultural sector. However, in addition to the nutritional assessment of the soil after fertigation, essential information to determine the viability of this proposal is the quantification of its toxicity to ecosystems, which justifies the need for ecotoxicological tests to obtain concrete data regarding environmental safety for the combined use of these effluents in agriculture. Therefore, in this work the organism Girardia tigrina was used as a bioindicator of contamination for freshwater ecosystems. As a result, it was observed that an effluent combined with 50% cattle slaughter effluent and 50% paint industry effluent, presented an LC50 at a concentration of 80% after 24 hours of exposure.
