Toxicity of Industrial Wastes and Waste Leaching Test Eluates Containing Organic Compounds

Hazardous properties of paint residues from the furniture industry

“…The same tests were also used in our previous study for wastes containing organic compounds [4]. Toxicity data were compared to the chemical concentrations of the analysed organic compounds in the leaching-test eluates.…”

“…In previous studies we have evaluated the suitability of different leaching-tests and ecotoxicological tests in order to discover useful combination of test methods for classifying and assessing the environmental hazard of inorganic or organic industrial wastes to be disposed of to a landfill [2][3][4]. In this study, we concentrated on the hazard assessment of the excess paint residues which were produced in the process of spray-painting furniture.…”

“…Therefore, there is also a need to develop leaching methods for organic compounds in wastes. If the chemical composition of the waste material is complex and not well-known, the ecotoxicological tests, according to our previous study [4], could be used in combination with chemical analyses to help the waste classification and to assess the potential environmental hazard of complex organic mixtures found in wastes.…”

“…However, this H14 criterion "ecotoxic" does not refer to specific methods. Owing to the hazardous properties of wastes, concern about and need for assessing the potential environmental hazard (H14 = "ecotoxic") has led to development of appropriate methods for measuring leaching and the ecotoxicological properties of waste materials [1][2][3][4].…”

Treatment of door-manufacturing factories wastewaters using CDEO and other AOPsA comparison

“…Several papers have been published in the literature during the recent years about the treatment of the wastes produced in a wooden-door manufacturing factory [1][2][3][4][5]. Initially, the use of a coagulation-flocculation technology followed by a biological oxidation stage appears as a promising alternative from the economy viewpoint, but due to the presence of toxic and/or biorefractory species, biological techniques are not initially considered to be efficient enough for the treatment of these effluents [6][7][8], and although the combination of a coagulation-flocculation process with a sedimentation or a flotation process is able to reduce the colloidal adhesives contents [9,10], this treatment does not act against soluble pollutants, and consequently it leads to a low COD removal. So, it can only be used as a complementary treatment and not as a final one.…”
