Biomonitoring and its in the assessment of the quality of wastewater treatment process

Improving the assessment of polluted sites using an integrated bio-physico-chemical monitoring framework

“…This approach requires the organisms' response to external stressors to be directly studied and quantified (Zwart, 1995). The measurements of an organisms' physiological, morphological and biomolecular responses, such as lethal concentration, survivorship (Bonnail, Macías and Osta, 2019), biomass, growth (Hybská et al, 2020), damage to DNA and other genetic markers (Vieira et al, 2019), phytotoxicity, cytotoxicity, genotoxicity, mutagenity (Cavusoglu et al, 2010;Bilal et al, 2016;Artico, Migita and Menezes, 2018;Olusola and Solomon, 2018) and locomotion responses (Salánki et al, 2003) have been utilised in previous research. Experiments may be conducted in bioassays / mesocosms designed on simplifications of the natural environment, to control for the complexities of real-world field conditions.…”

“…Experiments may be conducted in bioassays / mesocosms designed on simplifications of the natural environment, to control for the complexities of real-world field conditions. Monitoring the modification to the organisms behaviour provides an early warning of potentially significant ecological disturbances that may follow due to increasing contaminant / pollution levels (Cavusoglu et al 2010;Bilal et al 2016;Li et al 2018;Bonnail et al 2019;Hybská et al 2020).…”

“…Thus, biomonitoring potentially provides cost-effective solutions, which may be especially beneficial within low-to-middle income countries (LMIC) where frequent sampling alongside highly sensitive (and economically costly) chemical analysis is challenging (Japitana et al, 2018). The availability of sophisticated analytical instruments for a whole range of emerging compounds (e.g., surfactants, pesticides and antiinflammatory drugs) and their active metabolites, is more challenging for LMICs (Schöne and Krause, 2016;Prabhakaran et al, 2017;Calvo-Flores et al 2018;Gogoi et al 2018;Hybská et al 2020). Analysing trace, yet toxic, concentrations of substances is a resource intensive and expensive procedure.…”

The effect of manganese ions (II) on representatives of aquatic biota

“…The toxicity of water by biotesting using daphnia can be based on a change in their trophic activity against Chlorella, recorded by a change in the fluorescence signal of the latter [19]. Daphnia magna and Lemna minor refer to the difference in sensitivity of individual aquatic species, the methods of toxicity assessment based on them can accurately determine the ecotoxicological effects of emerging pollutants that are not removed by conventional water purification procedures [20]. Thus, using the example of the Bitha River, a comprehensive approach to the organization of system monitoring of the impact of landfill runoff on natural ecosystems is proposed, including an assessment of water toxicity by biotesting using Dafnia Magna, due to the content of manganese [21,22].…”

Identificação de compostos orgânicos em lixiviado de aterro sanitário durante tratamento por processo fenton

“…A eficácia do processo Fenton na remoção de material orgânico, nitrogenado e cor verdadeira já é bem documentada, mas são insuficientes, visto que vários compostos orgânicos das mais variadas classes podem contaminar solo, água e ar, deste modo, caracterizações mais robustas, que englobem parâmetros físicos, químicos e principalmente, identificação de compostos orgânicos podem auxiliar no entendimento do mecanismo de contribuição individual de cada composto orgânico e de suas interações na toxicidade do lixiviado (RIGOBELLO et al, 2015;PAIVA et al, 2011;REIS et al, 2017;MENDONÇA et al, 2009;HYBSKÁ et al, 2020;TIGINI et al, 2014). foram obtidos do sulfato ferroso (FeSO4.7H2O -PA) na sua forma granular.…”
