Análise quantitativa de parâmetros físico-químicos de agrotóxicos em indústria canavieira em região costeira da Paraíba

Abstract

The quantitative study of physico-chemical properties of compounds can be done using the soil sorption coefficients (Koc). The experimental measurement this process is difficult, expensive and time-consuming, thus is necessary a big effort has been put into attempting the estimation of Koc through statistical modeling. This study is identified the physico-chemical properties relevant to Koc pesticides values, used by Miriri agroindustry Food and Bioenergy S/A, using descriptors GRIND (GRid INdependent Descriptors). The quantitative study structure–property relationships (QSPR), indicates that the size, presence of aromatic rings and halogens increases the values Koc.
