Abstract Honey is a natural food derived from nectar and other natural plant secretions, collected, and processed by bees. To be safely consumed, it must be free of chemical contamination and have quality and identity parameters following established standards. The continuous search for agricultural productivity has increased the use of pesticides, widely used in crops. Residues of these compounds have been found in honey samples. This work aimed to determine the physicochemical parameters and verify the presence of pesticides in Apis mellifera bee honey sold in the regions of Pelotas and Rio Grande/in Rio Grande do Sul state (RS)/ Brazil. The honey samples presented values for the physicochemical parameters within the acceptable limits established by Brazilian legislation. Among the 100 pesticides investigated, the insecticide λ-cyhalothrin was detected in 50% of the samples in concentrations between 5.95 and 25.30 µg/kg. The calculated estimated daily intake was 1.0×10-4 µg/kg bw/day, below the maximum limits Brazilian and European legislation recommended. The results contribute to the generation of data on the quality of honey produced in the region, thus ensuring safe consumption, however, it causes an alert about the environmental contamination by the pollinators bee’s exposure to pesticides in regions with intense agricultural activity. secretions collected bees consumed standards crops Grandein RS/ RS / (RS) Brazil 10 investigated λcyhalothrin λ cyhalothrin 50 595 5 95 5.9 2530 25 30 25.3 µgkg µg kg 1.0×104 10104 1.0×10 4 1 0 1.0×10- bwday bw day bw/day recommended region consumption however s activity (RS 59 9 5. 253 2 3 25. 104 1010 1.0×1 101 1.0× 1.0 1.

Abstract This study evaluated relations among nutrients, bioactive compounds and antioxidant activity of commercial tomato varieties grown in field conditions in order to identify their biological potential by the Principal Component Analysis (PCA). Four commercial tomato varieties (Long Life, Italian, Khaki and Cherry), homogenized by their maturation stage (color, sugar/acidity ratio and pH) were evaluated regarding macro components (sugars, pectin and minerals) and functional ones (carotenoids, phenolic compounds and ascorbic acid). Cherry tomatoes stood out for their pectin and lycopene contents and their sugar/acidity ratio. Tomato samples were good sources of Cu and Ca. The PCA showed that the antioxidant potential of phenolic compounds was related to protocatecoic acid and quercetin concentrations. Italian and Cherry varieties stood out for their carotenoid contents. In field conditions, Cherry and Italian tomatoes were the best sources of functional compounds among the most common varieties found in the human diet.
