Brazil ranks 8th in the world for tropical fresh fruit production and exports almost 60% to Europe. A nationwide monitoring program "National Program Residues of Contaminants in Food (PNCRC)" checks compliance with the maximum residue levels, guaranteeing the quality of these commodities. Fruit samples (112) were analyzed between January 2006 and June 2007. Approximately 140 pesticides were evaluated by a multi-residue method using GC and HPLC methodologies. Dithiocarbamates were determined through conversion into carbon disulfide (CS2). A total of 76.8% of the samples were negative, with residues below the limit of detection. With reference to Brazilian legislation, 23.2% of the samples were positive (>MRL and not permitted for the crop (NPC), but only 4.4% were contaminated with multiple residues. A total of 14.3% of samples exceeded European Union MRLs. Samples of figs and persimmons had the highest violation rates. Action plans are being developed, with the cooperation of producers, to reduce pesticide residues.
The objective of this study was to identify pesticides found in infants' and children's diets. Fruits and vegetables were collected from 2004 to 2007 and analyzed using a multiresidue method. The most frequently detected residues were procymidone, captan, chlorpyrifos and chlorothalonil. Twenty-eight percent of the samples contained pesticide residues. Strawberry, pear, apple, peach and tomato contained pesticide levels of concern. Twenty-one pesticides were found with the estimated total mean daily intake greater than the acceptable daily intake for four of the pesticides. Residues of carbaryl, diazinon and methidathion exceeded regulatory levels in (apple, strawberry, and orange).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
