IMPROVING THE PERFORMANCE OF SPRAY OPERATORS THROUGH MONITORING AND EVALUATION OF INSECTICIDE CONCENTRATIONS OF PIRIMIPHOS-METHYL DURING INDOOR RESIDUAL SPRAYING FOR MALARIA CONTROL ON BIOKO ISLAND

Abstract Background Quality control of indoor residual spraying (IRS) is necessary to ensure that spray operators (SOs) deposit the correct concentration of insecticide on sprayed structures, while also confirming that spray records are not being falsified.Methods Using high-performance liquid chromatography (HPLC), this study conducted quality con

As an important tool for monitoring the marine environment, safeguarding maritime rights and interests and building a smart ocean, underwater equipment has developed rapidly in recent years.Due to the problems of seawater corrosion, excessive deep-sea static pressure and noise interference in the marine environment and economy, the applicability of
