Comparison of the toxicogenetic potential of sewage sludges from different treatment processes focusing agricultural use

Multi-taxon trends and the application of genotoxic biomarkers in the analysis of effluents from sewage treatment plant

“…Most of these studies have evaluated the effectiveness of treatments and the destination of the residues, such as the sludge. In the specific case of the sludge, one of the primary products of the treatment of sewage, caution is required for the disposal of this residue in agricultural soils or urban landscaping to avoid potential contamination and environmental damage [ 10 , 13 , 94 , 116 ]. The discharge of effluents into water courses constitutes a more complex scenario, and even when the legislation on the permitted concentrations of contaminants is respected, many studies have revealed negative impacts, in particular on fish [ 81 , 101 , 126 , 127 ].…”

“…The final destination of the residues produced by the sewage treatment process is also a major concern, due to their organic matter and nutrient content [ 10 ]. While these residues have been used in agriculture, they are often deposited in landfills or processed by incineration or pyrolysis [ 11 ].…”

Cemeteries as a source of environmental contamination: phytogenotoxicity of the biogenic amines cadaverine and putrescine

“…Some pollutants, depending on their concentration, may not directly interfere with plant growth, but may induce damage to the genetic material of organisms. Analyses performed with the species A. cepa have been frequently used as biomarkers of cytotoxicity, genotoxicity and mutagenicity, as they are e cient for this type of diagnosis (Fiskesjö 1993;Grant 1994;Mazzeo et al 2015;Sommaggio et al 2018;Caritá et al 2019).…”
