In recent years, plastic pollution has become one of the most concerning problems. It been demonstrated that microplastics (MPs) can be found in environmental compartments and wastewater discharges have identified as main pathways for these pollutants to enter natural environment. Knowing amount MPs coming from is important establish appropriate management mitigation. Most studies analyse grab samples collected at a specific time, whose content affected by outlier events deviate average...
Pharmaceutical products, as well insecticides and antimicrobials, have been extensively studied, but knowledge of their effects-especially those caused by mixtures with microplastics-on aquatic organisms remains limited. However, it should be borne in mind that the state on acute chronic effects for pharmaceuticals pesticides is not similar. In response, this investigation analyzed presence microplastics (polyvinyl chloride) impacts toxicity chlorpyrifos (an insecticide) triclosan...
Abstract Microplastics (MP) are contaminants able to cause adverse effects on organisms. MPs capable interact with other environmental contaminants, including pesticides, altering their toxicity. The objective of the study was research sublethal (enzymatic activity) pesticides alone and in combination MPs. Cholinesterase enzymes used as biomarkers determine evaluate produced organisms after exposure pollutants. This showed acetylcholinesterase (AChE) enzymatic activity tissue Solea...
Abstract This article proposes a method for the thermogravimetric analysis (TGA) of marine sediment suspected pollution by heavy metals, which may be appropriate selected region where regression equations relating W2 weight loss as independent variable and estimated metal abundance dependent have already been derived. Automated TGA then employed reconnaissance tool, to give rapid inexpensive predictive index quality. The has applied actual samples known content results compared with quality...
Characterization of organic matter in four sediments the influence area wastewater discharges was carried out by both chemical and thermal analysis order to assess their pollution level. Oxidisable carbon were calculated standard methodology laboratory. Thermogravimetry (TG), between 50 900° C, simultaneously performed oxidizing conditions on ground samples after three different pretreatments. Linear regression adjust results versus parameters provides better Pearson's coefficients, leading...
The biodegradation of a non‐ionic surfactant was evaluated by the evolution microbial activity and determination soluble present in effluent. Two lab‐activated sludge reactors/systems were fed with synthetic sewage, one which received addition different concentrations – 5 10 mg/L nonylphenol ethoxylates (NPEO). parameters employed this assay were: control (COD SS) (specific oxygen uptake rate dehydrogenase activity). removal NPEO production secondary metabolites monitored. Solid‐phase...
The degree of pollution marine sediments close to urban and industrial sites has been evaluated at various sampling points in the south Spain, using both chemical thermal analyses. Chemical variables including organic carbon, total nitrogen HEM (n-hexane extractable material) showed high levels samples. Thermogravimetry Analysis (TGA) sediments, previously ground treated, was also performed, under oxidizing conditions, from 50 900°C. first derivative TGA curves (DTG) parameters analyzed were...
The distribution, enrichment, and accumulation of heavy metals in the surface sediments Tangier Bay, Morocco, were investigated.Surface sediment samples from eleven locations Bay collected 2007 characterized for grain size, organic matter metal content (e.g.Fe, Mn, Cr, Cu, Ni, Pb, Zn Cd).The evaluation contamination status bay showed minor enrichment by factors (EF) calculation, corroborated pollution index (MPI).The results a Pearson correlation high positive correlations among carbon most...
