Fate, modeling, and human health risk of organic contaminants present in tomato plants irrigated with reclaimed water under real-world field conditions
2022, Science of the Total EnvironmentDetermination study of contaminants of emerging concern at trace levels in agricultural soil. A pilot study
2021, Science of the Total EnvironmentCitation Excerpt :These low concentrations can be related to losing in the irrigation system and/or the reservoir tank used for storing the contaminated recycled water solution in the field, due to degradation processes. As it has been found in literature, both furosemide, hydrochlorothiazide, and diazinon can be degraded by exposure to strong UV light (Cies et al., 2015; Mansour et al., 1997). The results could suggest that furosemide was highly sensitive to UV exposure with more than 30% of the compound degraded after 3 h of treatment, whereas diazinon was 50% degraded after 5 days of exposure to sunlight.
Oxygen dependence in the photoreaction of the pesticide metamitron
2017, Journal of Photochemistry and Photobiology A: ChemistryCitation Excerpt :As for other triazinones [1], photolysis of metamitron (see Fig. 1) is a main degradation pathway and has been extensively investigated in the past [2–8]. The main photolysis product of metamitron is desamino-metamitron [3–6,9], also found besides metamitron itself [10–12] in environmental samples [12,13]. Metamitron is one of the few examples of a pesticide with available information not only with respect to the photolysis leading to e.g. defined products but also for photophysical details to explain the photochemical reaction.
Degradation of the herbicide isoproturon by a photocatalytic process
2014, Comptes Rendus ChimieCitation Excerpt :The irradiation of isoproturon at 290 nm in water containing dissolved organic matter showed that photolysis in the absence of oxygen was faster during the first minutes of the irradiation period. Later on, the transformation seemed to slow down more gradually than in normal conditions, showing an increase in the half-life of isoproturon in water [12]. Experiments were performed in a 2-liter annular reactor (92 cm height, and inner and outer diameters of 3.2 and 4.2 cm, respectively).
A density functional theory and laser flash photolysis investigation of carbofuran photodegradation in aqueous medium
2012, Journal of Photochemistry and Photobiology A: ChemistryCitation Excerpt :Carbofuran (2,3-dihydro-2,2-dimethyl benzofuran-7-yl methyl carbamate) is a broad spectrum insecticide, nematicide and miticide [1]. Residual fate of Carbofuran has been extensively investigated in water, soil and in different experimental conditions [2–5]. In fact, several pathways were suggested for Carbofuran photodegradation, and the major observed photoproduct was phenol derivative [6].
Studies on atmospheric degradation of diazinon in the EUPHORE simulation chamber
2011, ChemosphereCitation Excerpt :In addition, Mansour et al. (1997) and Scheunert et al. (1993) reported that diazoxon, hydroxydiazinon, and the S-aryl isomer, isodiazinon, derived from the thiono–thiolo rearrangement, had been identified in aqueous solution and in water–soil suspension after UV light exposition.
