Selective-enrichment as a Tool to Obtain Microbial Degrading Consortia for the Remediation of Pesticide Residues
(2021)
Inadequate disposal of pesticides during their extensive use in agricultural practices may result in soil, surface, and groundwater pollution. These agrochemicals affect a wide variety of non-target organisms, and their ...
Removal of pharmaceuticals and ecotoxicological changes in wastewater using Trametes versicolor: A comparison of fungal stirred tank and trickle-bed bioreactors
(2021)
Hospital wastewater is loaded with pharmaceutically active compounds (PhACs), which sometimes end up in the environment unaltered due to the lack of effective and specific treatments. The use of white rot fungi, specifically ...
Bioaugmentation of pilot-scale slow sand filters can achieve compliant levels for the micropollutant metaldehyde in a real water matrix
(2022)
Metaldehyde is a polar, mobile, low molecular weight pesticide that is challenging to remove from drinking water with current adsorption-based micropollutant treatment technologies. Alternative strategies to remove this ...
Effects of the nitrification inhibitor nitrapyrin and tillage practice on yield-scaled nitrous oxide emission from a maize field in Iran
(2021)
Nitrification inhibitors can effectively decrease nitrification rates and nitrous oxide (N2O) emission while increasing crop yield under certain conditions. However, there is no information available on the effects of ...
Simultaneous degradation of pharmaceuticals in fixed and fluidized bed reactors using iron-modified diatomite as heterogeneous Fenton catalyst
(2021)
The aim of this study was to evaluate the use of pelletized iron-modified diatomite as heterogeneous Fenton catalyst for the removal of carbamazepine, clindamycin, gemfibrozil, ketoprofen, florfenicol, and sulfamethazine, ...
Nitrapyrin effectiveness in reducing nitrous oxide emissions decreases at low doses of urea in an Andosol
(2021)
In the tropics, frequent nitrogen (N) fertilization of grazing areas can potentially increase nitrous oxide (N2O) emissions. The application of nitrification inhibitors has been reported as an effective management practice ...
Investigation of pesticides and their transformation products in the Júcar River Hydrographical Basin (Spain) by wide-scope high-resolution mass spectrometry screening
(2019)
The Water Framework Directive 2000/60/EC implemented by the European Union established as the main objectives to achieve a “good ecological and chemical status” of the surface water and a “good quantitative and chemical ...
Nitrification inhibitor nitrapyrin does not affect yiel-scaled nitrous oxide emissions in a tropical grassaland
(2021)
Urea is the most common nitrogen (N) fertilizer used in the tropics but it has the risk of high gaseous nitrogen (N) losses. Use of nitrification inhibitor has been suggested as a potential mitigation measure for gaseous ...
Using Molecular Methods to Identify and Monitor Xenobiotic-Degrading Genes for Bioremediation
(2021)
Environmental pollution is a matter of increasing concern worldwide, for which new and innovative solutions are constantly required. Bioremediation, the transformation of contaminants into less toxic substances using ...
Ecological risk assessment of pesticides in the Mijares River (eastern Spain) impacted by citrus production using wide-scope screening and target quantitative analysis
(2021-06-15)
The widespread use of pesticides, especially in agricultural areas, makes necessary to control their presence in surrounding surface waters. The current study was designed to investigate the occurrence and ecological risks ...
