ResumoAtualmente, dentre os diferentes tipos de agrotóxico aplicados na agricultura, os carbamatos têm se destacado em virtude de sua elevada eficiência, facilidade de síntese e baixo custo. No entanto, o uso desregrado desses agrotóxicos, não seguindo as Boas Práticas Agrícolas (BPA), tem levado à contaminação do meio ambiente, destacando-se o acúmulo desses compostos nas águas superficiais (rios e lagos), subterrâneas e no solo. Além disso, muitos desses agrotóxicos são tóxicos para os seres vivos, principalmente por inibirem a ação de enzimas biológicas, como as colinesterases. Nesse contexto, o monitoramento de resíduos de agrotóxicos no solo e nas águas tornou-se imprescindível para a redução do impacto ambiental e aumento da segurança da saúde humana e animal, sendo realizado através da confirmação e quantificação desses resíduos, empregando-se diferentes técnicas analíticas. As técnicas de preparo de amostra mais empregadas e modernas para determinação analítica de resíduos de agrotóxicos carbamatos serão abordadas neste artigo.

Sample preparation techniques for determination of carbamate pesticides in water and soil AbstractCurrently, among the several kinds of pesticides employed in agriculture, carbamates have been widely used because of their high efficiency, ease of synthesis and low cost. However, the unjudicious use of these pesticides, not following Good Agricultural Practices, can have adverse effects on the environment, especially the accumulation of these compounds in surface waters (rivers and lakes), groundwater and soil. Furthermore, many of these pesticides are toxic to humans and animals, mainly due to their inhibition of enzymes, like cholinesterases. In this context, the monitoring of pesticide residues in soils and waters has become essential to reduce the environmental impact and improve the safety of human and animal health, being performed through the confirmation and quantification of these residues, employing different analytical techniques. The most frequently used techniques and modern sample preparation for analytical determination of carbamate pesticide residues will be discussed in this paper.

“…A range of molecularly-imprinted polymer-based sensors have been investigated using different transduction techniques, including: acoustic wave , Kugimiya et al, 1999, Liang et al, 2000, Matsuguchi et al, 2006, Percival et al, 2001, Yilmaz et al, 1999, potentiometry (Javanbakht et al, 2008), capacitance , conductometry (Kriz et al, 1996, Sergeyeva et al, 1999, voltammetry (Prasad et al, 2005), colorimetry (Stephenson et al, 2007), surface plasmon spectroscopy (Tokareva et al, www.intechopen.com 2006), and fluorescence (Chen et al, 2004, Jenkins et al, 2001, MorenoBondi et al, 2003 detection. Moreover, the molecularly-imprinted polymers can also be utilized for selective solid-phase separation techniques (Mahony et al, 2005, Masque et al, 2001, including electrophoresis and chromatography. Furthermore, it has been found that the analytical signal can often be enhanced by employing nanoparticle labeling of guest molecules (Stobiecka et al, 2009).…”

“…The availability and type of the functional groups in the template molecule play important role. Also the structure, solubility of the template and the end-use of imprinted material will decide about imprinting method [12]. For this experiment non-covalent approach of molecular imprinting was applied.…”
