- Abstract
The use of pesticides in agriculture has been considered worldwide as one of the most important ways to increase agricultural production; however, its use has been accompanied by side effects, which represent a danger to humans and biota. The aim of this study was the development of a miniaturized method for the determination of organochlorine compounds in surface water samples from the states of Colima and the municipality of Salamanca, Guanajuato. A method for the determination of aldrin, endrin, dieldrin, heptachlor, lindane and dichloro diphenyl trichloroethane in samples of surface water, using the solid phase microextraction technique and gas chromatography coupled to spectrometry of masses was developed, validated and applied. Samples were obtained from two states of Mexico, in the state of Colima two samplings were carried out, in October 2012 and March 2013, belonging to the dry and wet season in 25 sites in the main bodies of water and runoff in the state. In the municipality of Salamanca, Guanajuato, four samples were taken in a single sampling, in October 2012, on the Lerma River as it passed through the city of Salamanca. The results show that the developed and validated method was accurate, precise, sensitive and inexpensive for the quantification of lindane, heptachlor, aldrin, dieldrin and endrin, which are of environmental interest due to their toxic characteristics. Likewise, in the samples from the state of Colima, all pesticides were found below the detection limit; however, the presence of triclosan, chlorophenyl pyrrolidine, chlorophenyl methanone, and heptachlor epoxide could be determined. While in the Lerma river samples, the concentration of the pesticides aldrin, lindane, heptachlor and dieldrin was detected.
