To assess whether the maximum residue level proposed to CCPR, for use as a MRL, provides sufficient consumer safety, available residue data are combined with cultural dietary information to estimate potential residue intake by consumers. The consumer is considered to be adequately protected when estimated dietary intake of pesticide residues does not exceed the acceptable daily intake (ADI) or ...

Residues of the polar pesticide pymetrozine were compared using two methods: hydromatrix and liquid-liquid extraction (LLE). The biological half-life and the final residue level were investigated using Aster scaber over a 10-days cultivation period. The respective biological half-lives of the pesticide were 4.2 and 3.5 days at the recommended and double dose. The final residue levels were 1.28 ...

The present paper reviews various pathways that will lead to reduction of organic solvent usage in pesticide residue analysis. Considerable reduction of solvent consumption can be achieved by miniaturizing the scale of sample extraction and cleanup and by simplifying the analytical procedures. Adoption of new analytical techniques, such as solid-phase microextraction and supercritical fluid ext...

The first aim of this paper was to evaluate pesticide residue levels of berry fruit samples. The second aim was to analyze health risks associated with pesticide levels. The monitoring was conducted on samples from producers in north-eastern Poland, during the time period 2005-2010. In total, 241 samples of berry fruit were analyzed using validated and accredited multi residue methods. The stud...
