01 Jan 2000TL;DR: The levels of FB1 and FB2 in the samples collected during January 1998 were significantly higher than the samples collection during the period from October 1996 to January 1997 and during the month of January 1998.
Abstract: Fumonisins B1 (FB1) and B2 (FB2) were determined in 35 samples of corn flour and corn grits destined for human consumption and purchased directly from Buenos Aires food shops and supermarkets from October 1996 to January 1997 and during the month of January 1998. During the first period of sample collecting, 16 out of 19 samples were found to be contaminated. Considering all 19 samples, contamination levels were between not detected and 1860 ng/g FB1, and from not detected to 768 ng/g FB2. During the second period all 16 samples were found to be contaminated with levels ranging from 75 to 4987 ng/g FB1, and from not detected to 1818 ng/g FB2. The levels of FB1 and FB2 in the samples collected during January 1998 were significantly higher than the samples collected during the period from October 1996 to January 1997. No significant difference was found in terms of fumonisin levels between the branded and unbranded samples.

TL;DR: In this paper, the authors assess two headline indicators of ecosystem status, namely their potential threat status and current spatial protection levels; and use Systematic Conservation Planning (SCP) to prioritise specific areas for protection to achieve networks of MPAs that are representative of national and regional biodiversity.

TL;DR: A quick, simple and low-cost routine analytical method was developed for the screening and confirmation of chloramphenicol in honey by LC–MS/MS, and within-laboratory CV reproducibility at the lowest concentration was <10%.
Abstract: Chloramphenicol (CAP) is a broad spectrum antibiotic used in the treatment of human and animal diseases. However, CAP can exhibit toxic effects in certain susceptible individuals, causing bone marrow depression, including fatal aplastic anemia. As this condition is dose-independent, CAP has been banned for use in food-producing animals, including honeybees. In this study, a quick, simple and low-cost routine analytical method was developed for the screening and confirmation of chloramphenicol in honey by LC–MS/MS. Sample clean-up takes only two steps without SPE procedure and with recoveries >97%. Honey samples were selected from several producers in Brazil and diluted in a small amount of water. After fortification and addition of d s-chloramphenicol as internal standard, the samples were extracted with ethyl acetate. Complete validation of the method was performed on the basis of EU decision 2002/657. Within-laboratory CV reproducibility at the lowest concentration was <10%. An evaluation of two differe...
