Several different Advanced Oxidation Processes (AOPs) including ozonation at pH 6.5 and 10, photolysis heterogeneous photocatalysis using TiO(2) as semiconductor dissolved oxygen electron acceptor were applied to study the degradation of glyphosate (N-phosphonomethyl glycine) in water. The degree degradation, reactions kinetic formation major metabolite, aminomethyl phosphonic acid (AMPA), evaluated. Ozonation 10 resulted maximum mineralization glyphosate. It was observed that under...
A large variety of organic and inorganic compounds may be found in wastewater which can contribute to environmental contamination. Oxidation processes with ozone (O3; O3/UV; O3/H2O2; O3/TiO2; O3/Mn+2) the use pre- or post-treatment combined biological has been extensively studied for treatment effluents. The aim this work was evaluate potential ozonation process several industrial wastewaters, namely effluents from paper mills, textile, whey (dairy industry), pharmaceutic sand pesticides plants.
A simple method using LC/MS/MS was developed and validated to determine residues of malachite green (MG) leucomalachite (LMG) in fish fillet. modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) technique used perform the sample preparation. The optimal extraction cleanup conditions were established an experimental design. validation parameters obtained both MG LMG complied with requirements by regulatory agencies for presence such substances fish, which establish that must...
The treatment of paper mill effluent for COD, TOC, total phenols and color removal was investigated using combined activated sludge-ozonation processes single processes. sludge-O3/pH 10 able to remove around 80% TOC from Kraft E1 effluent. For the phenols, efficiency 70%. ozonation post carried out at pH 8.3 also showed better results than process. obtained were 75.5, 59.1, 77 52.3%, respectively. difference in concentrations free radical produced by affected mainly phenol values.
Entomopathogenic fungi can provide a set of ecological services, such as suppressing arthropod pests and plant pathogens. In this study, novel indigenous Beauveria caledonica (Bc) strains were isolated from naturally infected banana weevils (Cosmopolites sordidus) occurring in commercial plantations Brazil.The prevalence infection by Bc on field-caught C. sordidus ranged 1.3% to 12.9%. Similar the bassiana tested, none caused more than 50% weevil mortality at concentration 1 × 108 conidia...
Physicochemical and ecotoxicological measurements were employed to appraise the water quality of Corumbataí River raw (RW) intake, that its filtered (FW) treated (TW) waters, processed by Water Treatment Plant (WTP) Piracicaba (SP,Brazil) during 2010. Some herbicides: ametrine, atrazine, simazine tebuthiuron, measured, with levels ranging from 0.01 10.3 µg L-1. These lower than those required produce effects aquatic life based on published literature. Similarly, trihalomethanes, such as...
The practice of intensive herbicide use in the sugarcane industry has a high risk compromising quality water and organisms that live there due to losses through runoff, leaching other processes. In this work, dynamics four herbicides present three different mixtures were evaluated their incorporation elimination muscle tissue tilapia (Oreochromis niloticus). highest mean values bioconcentration factors 1.730 for ametryn, 0.891 tebuthiuron, 0.322 hexazinone 4.783 diuron. Diuron presented...
ABSTRACT In this study, the impact of ozone concentration (14 and 7mg/L−1 applied for 120min) pH (10 12) on color removal, reduction dissolved organic matter (DOC) total phenol Kraft E1 effluent was investigated. The degradation kinetics all parameters at 12 were slower than those 10. 10 ceased after approximately 120min, while ozonation 12, still being consumed even 5h treatment. When dose increased, removal efficiency increased; however, DOC continued limited.
The widespread use of moxidectin (MOX), a parasiticide used in the sheep breeding, has induced parasite resistance Brazilian farms.As consequence, farmers often increase dose and frequency drug utilization, disregards safety meat or milk.In order to establish adequate therapeutic treatment it is necessary know pharmacokinetics animal's body.Thus, high performance liquid chromatography-electrospray ionization-tandem mass spectrometry (HPLC-ESI-MS/MS) method was developed for determination MOX...
Cancer is a complex disease that can also affect the younger population; however, it responsible for relatively high mortality rate of children and youth, especially in low- middle-income countries (LMICs). Besides that, lipidomic studies this age range are scarce. Therefore, we analyzed blood serum samples from young patients (12 to 35 years) with bone sarcoma (osteosarcoma) compared their lipidomics ones control group samples, named healthy (HC group), using NMR LC-MS techniques....
Abstract A large variety of organic and inorganic compounds can be found in wastewater from industrial processes. In this work, Advanced Oxidative Processes (AOPs) have been applied for the control water pollution ozonation different effluents was investigated. Wastewater textile, kraft E1 cheese manufacturing processes were chosen as examples effluents. The efficiency substrate mineralization has comparatively analyzed by decrease total carbon (TOC), color, toxicity. results revealed that...
A multiresidue method for detecting and quantifying sulfonamides (sulfapyridine, sulfamerazine, sulfathiazole, sulfamethazine, sulfadimethoxine, sulfamethoxazole, sulfamethoxypyridazine) trimethoprim in tilapia fillet ( Oreochromis niloticus ) using liquid chromatography coupled to mass spectrometry was developed validated. The sample preparation optimized the QuEChERS approach. chromatographic separation performed a C18 column 0.1% formic acid water acetonitrile as mobile phase isocratic...
Aims: Epiphytic bacteria, isolated from Deschampsia antarctica, were screened for their potential to inhibit the plant pathogen Botrytis cinerea, causal agent of gray mold disease strawberry pseudofruits. This phytopathogenic fungus is more active and serious in temperate climate where temperatures are lower. Methodology: The approach involved isolation characterization bacteria phyllosphere D. antarctica evaluation antifungal activity. Results: A total 56 bacterial strains only one them,...
OZONATION (Mn II AND Cu II) IN PHENOL DEGRADATION.This paper discusses the results obtained with homogeneous catalytic ozonation [Mn (II) and (II)] in phenol degradation.The reduction of total phenols organic carbon (TOC) ozone consumption were evaluated.The efficiency degradation (total removal) at pH 3, process (II)), increased from 37% to 55% while TOC removal 4 63% a seven-minute treatment.The 10 was 43% 39% for removal, respectively.The presence both metallic ions 2+ +2 ) resulted...
The use of aerial application with electrostatic charge is an alternative to improve the quality insecticide applications in soybean crop. objective this study was evaluate drift and chemical control caterpillar stink bug complex promoted by crop, using spray system rotary atomizers. Thiamethoxam + Lambda cyhalothrin applied a Cessna 188 Ag Truck agricultural aircraft two treatments: SPE® system, 54 SPE-5 nozzles 10 L ha-1 rate, Travicar model® 05165 atomizer, 55° angle blades rate 20 ha-1....
Although insecticides are essential for the effective pest management, development of sustainable formulations remains a challenge in modern agriculture.
