ABSTRACT

Resíduos do inseticida e nematicida carbofurano e de seu principal metabólito 3-hidroxicarbofurano foram averiguados em tabuleiros de arroz irrigado e em áreas adjacentes para controle do gorgulho aquático da espécie Oryzophagus oryzae Lima, 1936. As amostras foram coletadas no período de 6/9/1999 a 4/5/2000 e analisadas por cromatografia a líquido de alta eficiência (HPLC) utilizando-se detector de fluorescência. Não foram detectados resíduos de carbofurano e de seu metabólito 3-hidroxicarbofurano dentro dos limites de determinação do método. (AU)


The presence of residues of the insecticide and nematicide carbofuran, used for weevil (Oryzophagus oryzae Lima 1936) control, and its principal metabolite 3-hydroxycarbofuran were evaluated in soil and sediment plots from paddy rice fields and adjacent areas. The samples were analyzed using a high-performance liquid chromatography and fluorescence detector. Carbofuran and 3-hydroxycarbofuran residues were not detected in any sample in amounts above the methods detection threshold. (AU)

ABSTRACT

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).
