“…Analytical methods that are used to monitor pesticide levels in food should be capable of measuring pesticide residues at very low levels (Taylor et al, 2002). In addition, these methods should be able to identify and quantity the types of pesticides found in food products (Sannino et al, 2004).…”

Liquid chromatography in conjunction with tandem mass spectrometry was used to directly quantify of 47 pesticide residues from cooked wheat flour and polished rice, which are the most widely consumed cereals in the Republic of Korea. The sample clean-up was carried out according to the method established by the Korea Food and Drug Administration. The mobile phase for liquid chromatograpy separation consisted of water and 5 mM methanolic ammonium formate. Tandem mass spectroscopy experiments were performed in electrospray ionization positive mode and the multiple reaction monitoring mode. The matrix effects estimated for the 47 pesticides had a mean value of 99% and ranged from 45 to 147%. High recoveries (70-140%) and relative standard deviations (£20%) were achieved for most of the pesticides tested. The method used in this study allowed for rapid quantification and identification of low levels of pesticides in cooked wheat flour and polished rice samples. Of the screened pesticide residues, only tricyclazole and fenobucarb were found in polished rice samples. However, no samples contained residues above the MRL established by the Korea Food and Drug Administration.

“…61 During the last decade, an effort has been put in order to develop analytical methods 62 for trifloxystrobin analysis in foodstuffs. The first approach was described in 2002 and 63 comprised liquid chromatography coupled to tandem mass spectrometry (MS) with 64 electrospray ionization (Taylor, Hunter, Hunter, Lindsay, & Le Bouhellec, 2002 195 Antibody selectivity was determined in homologous assays using the i-cELISA format.…”

“…Dentre as etapas analíticas empregadas na determinação de multirresíduos de agrotóxicos, a extração dos analitos é considerada uma das mais críticas e importantes, uma vez que engloba procedimentos laboriosos que demandam tempo, custo elevado e geram grandes quantidades de resíduos tóxicos [94][95][96][97] . Outras adversidades a serem superadas nesta etapa é a extração simultânea de compostos com propriedades físico--químicas diferentes, em baixa concentração e em diferentes matrizes.…”

ResumoA presente revisão tem como objetivo reunir em um único manuscrito informações desde a produção agrícola do morango até os aspectos negativos que podem influenciar e atingir o meio ambiente ou gerarem preocupações com a saúde dos trabalhadores rurais e consumidores que tenham contato direto com o meio ambiente ou que consomem o morango in natura. O morango é uma das culturas que lideram, desde o ano de 2002, o ranking dos alimentos mais contaminados por resíduos de agrotóxicos no Brasil. A cromatografia líquida moderna é uma das técnicas analíticas mais desenvolvidas e empregadas para determinação de resíduos de agrotóxicos em alimentos. Palavras-chaveCLAE; agrotóxicos; morango. Strawberry: food, environmental and sanitary concerns, monitored by modern liquid chromatography AbstractThis review aims to present information in a single manuscript initiating with the agricultural production of strawberries and concluding with the negative aspects that influence environment or generate concerns about the health of farm workers and consumers who have direct contact with the environment or, even the consumers of fresh strawberries. Strawberry crops are those that leads, since the year 2002, the ranking of the foods most contaminated with pesticide residues in Brazil. Modern liquid chromatography is one of the most developed analytical techniques and is thus often employed for the determination of pesticide residues in foods.
