Abstract: Honeybees and bee products are potential bioindicators of the presence of contaminants in the environment, enabling monitoring of large areas due to the long distances travelled by bees. This work evaluates the use of bee pollen as a bioindicator of environmental contamination by pesticides. A GC-MS/MS analytical method for multiresidue determination of 26 different pesticides in pollen was developed and validated in accordance with the recommendations of the European Union SANCO guide. Environmental monitoring was conducted using the analysis of 145 pollen samples collected from ten beehives in the experimental apiary of Embrapa in Jaguariúna (São Paulo State, Brazil). Bioallethrin and pendimethalin were identified in four and eighteen samples, respectively, at concentrations below the LOQ of the method (25 ng g?1). Passive sampling with polyurethane foam discs was used as a control, and no pesticides were found. The detection of pesticide residues in seven samples (33%) from commercial apiaries in Ribeirão Preto (São Paulo State) confirmed the efficiency of the analytical method and the need for environmental monitoring for the presence of pesticide residues. The results demonstrated the potential of bee pollen as a bioindicator of environmental contamination by pesticides. |

Abstract: The constant study of the morphophysiological characteristics becomes fundamental so that one can promote the improvement of how one occurs to the dynamics of forage production. The objective of this study was to evaluate the structural characteristics and biomass production of the tamani-grass submitted to nitrogen fertilization. A randomized complete block design was used, with three replications. The treatments consisted of nitrogen doses equivalent to 0, 100, 300, 600 and 1,200 kg ha-1 year-1. The analyzed variables were: accumulation rate of total harvestable forage, rate of accumulation of harvestable green forage and live material and dead material. The rates of total collapsible forage (RTCF) and harvestable green forage (RHGF) increased linearly with increasing nitrogen rates. The dose of 1200 kg ha-1 year-1 of N provided increases of 180% for RTCF and 175% for RHGF. The MV / MM ratio presented quadratic response, maximizing in the equivalent dose of 597.05 kg ha-1 year-1 of nitrogen, with an estimated value of 99.98. The structural characteristics and biomass production of tamani-grass were increased by the nitrogen up to the equivalent dose 1200 kg ha-1 year-1. |
