A voltametria de onda quadrada foi utilizada com o eletrodo de gota suspensa de mercúrio para determinar o conteúdo de Fenitrothin em três diferentes formulações comerciais. Em princípio, as determinações de Fenitrothion foram feitas em uma solução tampão BR (pH 10,5) preparada com água pura. Nestas soluções, os limites de determinação e quantificação encontrados foram 5,20x10 μmol L (1,44 ppb)...

As with other insects, resistance to insecticides has become a limiting factor in the use of insecticides to control mosquitoes. Mosquito control depended on the use of insecticides for a long time (initially organochlorines, followed by organophosphates, carbamates and pyrethroids). This study aimed to determine the susceptibility of Anopheles arabiensis adult to the public health and agricult...

We have previously shown that exposure to exogenous androgens causes female sticklebacks (Gasterosteus aculeatus) to produce the glue protein, spiggin, in their kidneys. This protein can be quantified by an enzyme-linked immunosorbent assay developed and validated at the Centre for Environment, Fisheries and Aquaculture Science. Here we report the development of an in vivo test for the detectio...
