Reliable analytical results are necessary to ensure effective consumer protection and the use of certified reference material (CRM) is an important tool for quality assurance. The Brazilian Metrology Institute (Inmetro) studied the feasibility of the production of a candidate CRM of chloramphenicol (CAP) in milk. CAP is an antibiotic banned for treatment of food-producing animals. A minimum required performance limit (MRPL) for analytical methods of 0.3 lg kg1 was set by the European Community for the detection of CAP residues in food matrices. Liquid chromatography with isotope dilution mass spectrometry (LC? IDMS) was employed for CAP determination and water content was measured by Karl Fischer coulometric titration. The feasibility study showed milk powder processed with both spray dryer and lyophilization lead to the best results, showing good degree of inhomogeneity for CAP residues (5.0%) and for water content (3.0%), therefore demonstrating that the production of this candidate CRM was feasible |

Sulfur (S) is an important nutrient very little studied in soybean, which has resulted in the lack of information for the establishment of critical levels in soils and response curves of crops to this nutrient. In fact, soybean occupies extensive areas in Brazil and the addition of fertilizers requires rational recommendations. In 1998/99, sulfur research was conducted at several locations: Ponta Grossa, Paraná, in a alic oxisol (latossolo vermelho-escuro álico) soil, Londrina, Paraná, in a eutrofic oxisol (latossolo roxo eutrófico) soil, Sambaíba, Maranhão, in a dystrofic oxisol (latossolo vermelho-amarelo distrófico) soil, and Rondonopólis, Mato Grosso, in a dystrofic oxisol (latossolo vermelho-escuro distrófico) soil, to determine the effects of S on soybean yield. The experimental design was radomized blocks, with five S levels (zero; 25; 50; 75 and 100 kg ha-1). The source was the elementary sulfur, with 98% of S. The S response curves, across four locations, and year by averages, showed a quadratic response of grain yield, and highest production (3120 kg ha-1) was obtained with 50 kg ha-1 of S. The yield of 3115 kg ha-1, obtained with foliar application of S was similar to the best level of S applied to soil, showing this to be a reliable alternative, in case of is S defficiency. |
