“…This leads to the thought that maybe this classification method has an underestimated toxicity assessment, disregarding the harmful effects of industrial landfill toxic loads in aquatic ecosystems. Similar results were reported by Silva et al [48], who applied a battery of acute toxicity tests with Scenedesmus subspicatus, Vibrio fischeri , and Daphnia magna to textile, metal-mechanics, and automotive solid wastes. The researchers observed that in some cases the hazardous potential of industrial sludge was underestimated, so they affirm that the current Brazilian regulation (NBR 10004) is not always appropriate to evaluate the environmental impact from a solid waste.…”

Industrial wastes may produce leachates that can contaminate the aquatic ecosystem. Toxicity testing in acute and chronic levels is essential to assess environmental risks from the soluble fractions of these wastes, since only chemical analysis may not be adequate to classify the hazard of an industrial waste. In this study, ten samples of solid wastes from textile, metal-mechanic, and pulp and paper industries were analyzed by acute and chronic toxicity tests with Daphnia magna and Vibrio fischeri. A metal-mechanic waste (sample MM3) induced the highest toxicity level to Daphnia magna(CE50,48 h = 2.21%). A textile waste induced the highest toxicity level to Vibrio fischeri (sample TX2, CE50,30 min = 12.08%). All samples of pulp and paper wastes, and a textile waste (sample TX2) induced chronic effects on reproduction, length, and longevity of Daphnia magna. These results could serve as an alert about the environmental risks of an inadequate waste classification method.

“…S/S technique purposes at immobilizing pollutants by transform them into a less soluble form (stabilization), and enclose them by the creation of a sturdy matrix (solidification) [4]. As declared by [5], it is recognized as "the best demonstrated offered technology" for industrial waste treatment involve heavy metals. Basically, the S/S technique contains a combination of chemical binders with sludge and water before cementitious mixture is cured for many days.…”

This research explored the potential to use IPA as a binder for the treatment of industrial waste sludge. Within the study, Incinerated Paper Ash (IPA) was used together Ordinary Portland Cement (OPC), a main material employed in solidification/stabilization (S/S) methodology to treated industrial ceramic sludge. The issues created by OPC in sustain the surroundings and cost force the new material must replace OPC as binder within the treatment methodology. The impact of the various IPA compositions within the system has been examined. The Unconfined Compressive Strength (UCS) and Toxicity Characteristic Leaching Procedure (TCLP) were used to assess the viability of IPA in sludge treatment once 28 days. The great result of compressive strength and decrease in heavy metals shows the potential of IPA in OPC replacement.

“…However, there is a lack of data from detoxification studies about the use of stabilization ponds for the treatment of landfill leachates. Studies have shown that physical-chemical parameters do not always convey the toxic potential of chemicals in the leachate, as those parameters often do not predict the relationship between living organisms and contaminants (Flohr et al, 2012;Matias and Flohr, 2015;Silva et al, 2011). Thus, the toxicological analysis of complex wastewater, including synergistic and additive effects, is an important tool in risk assessment and decision-making for environmental management (Matias and Flohr, 2015).…”

The performance of a pilot stabilization ponds system was evaluated for the treatment of sanitary landfill leachate, focusing on effluent detoxification. Three serial ponds (anaerobic-P1, facultative-P2, and maturation-P3) were evaluated during two different operational conditions: natural condition (period 1) and 24 hours of artificial aeration in P2 (period 2). The ponds system exhibited removal efficiencies of 53% for soluble chemical oxygen demand (SCOD), 81% for filtered biochemical oxygen demand (FBOD), and 84% for NH4+-N during period 1 and 70% for SCOD, 80% for FBOD, and 96% for -N during period 2. Most metals (Fe, Cu, Cd, Zn, Cr, Ni, and Pb) and organic compounds in the leachate were significantly reduced in the treatment system, with greater reductions during period 2. Moreover, toxicity tests demonstrated the capacity of the system to reduce the toxicity of the raw leachate (up to 89% toxicity reduction).
