Entomological surveillance for phlebotomines in the metropolitan region of Aracaju, Brazil.

Records of infections by Leishmania spp. (Kinetoplastida: Trypanosomatidae) have been occurring in the last decade in Sergipe, Brazil. The capital, Aracaju, alone accounted for 44% of the total cases of the state for the visceral form between 2007 and 2016, with high numbers also in other municipalities that make up the metropolitan region.

Optimizing difenoconazole degradation via sequential photoelectrochemical oxidation and biodegradation treatments.

The growing global demand for food has intensified the use of pesticides in conventional agriculture, raising concerns about their environmental contamination and persistence. This study proposes an integrated strategy for the degradation of difenoconazole (DFZ), combining photoelectrochemical oxidation (PECO) with biodegradation. A mixed metal oxide anode, Ti/(RuO)(SbO)(TiO) was successfully synthesized via the ionic liquid method, and a mangrove-derived Bacillus sp.

Phlebotominae Fauna (Diptera: Psychodidae) and the Spatial Distribution of Species in Sergipe, Brazil.

Some sand fly species are the vectors responsible for the transmission of Leishmania spp. (Kinetoplastida: Trypanosomatidae), the etiological agent of leishmaniasis, and in the state of Sergipe, the two main forms of the disease (visceral and cutaneous) are recorded. Few works show information about the species that form the Phlebotominae fauna in Sergipe.

Enhanced HCB removal using bacteria from mangrove as post-treatment after electrochemical oxidation using a laser-prepared Ti/RuO-IrO-TiO anode.

The environmental persistence of hexachlorobenzene (HCB) is a challenge that promotes studies for efficient treatment alternatives to minimize its environmental impact. Here, we evaluated the HCB removal by electrochemical, biological, and combined approaches. The electrochemical treatment of 4 μM HCB solutions was performed using a synthesized Ti/RuO-IrO-TiO anode, while the biological treatment using mangrove-isolated bacteria was at 24, 48, and 72 h.

Novel Ti/RuOIrO anode to reduce the dangerousness of antibiotic polluted urines by Fenton-based processes.

The treatment of hospital wastewater is very complex, so treating polluted human urine is a significant challenge. Here, we tested a novel MMO-Ti/RuOIrO electrode to reduce the ecotoxicity risk of hospital urines contaminated with antibiotics. This electrode was used as the anode in electro-Fenton (EF) and photoelectro-Fenton (PhEF) processes.

Biodegradability improvement of clopyralid wastes through electrolysis using different diamond anodes.

The use of boron-doped (BDDs) anodes for efficient removal of complex organic molecules, such as organochlorine compounds, is well stated in the literature. However, the role of the different characteristics of this anode on the transformation of these type of contaminants into more biodegradable molecules is a topic of interest that need to be clarified when aimed an efficient combination of an electrochemical system as a previous step to biological treatment. In this work, improvement in the biodegradability of synthetic wastes polluted with clopyralid, as an organochlorine model compound, is studied after electrolysis with different BDDs in the presence of the two most common supporting electrolytes (containing sulfate or chloride ions).

Influence of the doping level of boron-doped diamond anodes on the removal of penicillin G from urine matrixes.

The objective of this study is to understand the influence of the characteristics of boron-doped diamond anodes on the degradation of Penicillin G contained in urine. Therefore, five commercial BDD anodes with different boron doping levels (100 ppm - 8000 ppm) were studied. These electrodes were characterized by cyclic voltammetry, electrochemical impedance spectroscopy, and electrolysis.
