Ants are important components of food webs in several ecosystems. In anthropic areas, they can be used as bioindicators of the environmental impacts caused by many factors or in the evaluation of the dynamics of the recovery of an area after a certain disturbance. In this context, ants can be used as bio...
In forensic toxicology, the detection of toxic chemicals from human bone marrow is often used in cases with an extended post mortem interval; however, in veterinary medicine, this practice is not used. Therefore, this study was performed to investigate the suitability of bone marrow for toxicological ana...
Abstract Three phosphate solubilizing bacteria were isolated and identified by 16S rRNA sequencing as Pseudomonas putida, Pseudomonas sp and Pseudomonas fulva . The strains were subjected to plant biochemical testing and all the PGPR attributes were checked in the presence of pesticides (chlorpyrifos an...

Background: Biodegradation is a reliable approach for efficiently eliminating persistent pollutants such as chlorpyrifos. Despite many bacteria or fungi isolated from contaminated environment and capable of degrading chlorpyrifos, limited enzymes responsible for its degradation have been identified, let ...

ABSTRACT Background: Since 1960s, the organophosphate pesticide chlorpyrifos has been widely used for the purpose of pest control. However, given its persistence and toxicity towards life forms, the elimination of chlorpyrifos from contaminated sites has become an urgent issue. For this process bioremed...

Introducción: Teniendo en cuenta el daño potencial que se genera en la salud humana en la región de Urabá (Antioquia, Colombia) a través de la utilización de agrotóxicos, con énfasis en clorpirifos, se realizó esta investigación donde se evalúan los niveles de contaminación de los operarios e...
Chlorpyrifos (CPF) is an organophosphate compound used worldwide as a pesticide in agriculture that, after subcutaneous injection, keeps acetylcholinesterase (AChE) activity inhibited within an organism for months. Ample clinical and experimental evidence shows that CPF exposure induces relevant and pers...
En el cultivo de plátano de explotación comercial se utilizan bolsas de polietileno de baja densidad (PEBD) impregnadas con clorpirifos (insecticida) a 1%, como principal práctica de protección de frutos del ataque de plagas que demeritan su apariencia. No existen estudios que aporten datos sobre la ...
In the present study, an organophosphorus compound Coroban (active ingredient chlorpyrifos – E.C. 20%) was used. In short-term exposure the fish were subjected to 0.8 of 96h LC50 value of chlorpyrifos (1.76 mg L-1) for 96h. In long-term exposure the experiment was performed for 28 days by using 0.2 of ...
O presente estudo foi realizado com o objetivo de avaliar em condições de laboratório e campo, a eficiência de um inseticida Teste (à base de cipermetrina, clorpirifós e citronela), no controle do cascudinho dos aviários (Alphitobius diaperinus). Em laboratório, o produto foi testado sobre inseto...
