ANALYSIS OF ALDICARB IN SURFACE WATER FROM THE PARANÁIBA RIVER
Journal Title: Periódico Tchê Química - Year 2017, Vol 14, Issue 27
Abstract
The pesticide aldicarb is the most toxic active ingredient registered in all national territory, standing out for its extreme acute toxicity. In the environment, mainly in the water resources, several studies have demonstrated the potential of contamination of aldicarbe. The Paranaíba River cuts off the municipality of Itumbiara-GO, a region considered an important economic center in the south of the state. Along the Paranaíba River Basin there is a wide range of crops, such as sugarcane, corn, soy, cotton. This work aimed to quantitatively analyze the occurrence of aldicarb contamination in surface waters of the Paranaíba River, in addition to conducting a theoretical study of the river. For this purpose, the liquid-liquid extraction with low temperature partitioning (LLE-LTP) and high-performance liquid chromatography (HPLC-UV) analysis were used. In the surface water samples of the river analyzed, no aldicarb contamination levels were found or the concentrations were below the detection limit of the LLE-LTP and HPLC-UV method.
