1. Nutritional quality and sensory attributes of date palm spathes beverage supplemented with pollen grains
Abstract The aim of this study was to fortify date palm spathes beverage with pollen grains. The nutritional quality and sensory attributes of the developed products were evaluated. The results showed that pollen grains significantly (P < 0.05) influenced the nutritional and sensory qualities of date palm spathe beverages. With minor exceptions, fortificatio

5. Labile copper and zinc fractions under different salinity conditions in a shipyard area in the patos lagoon estuary, south of Brazil
Copper and zinc are common elements in paint residues and can be toxic to estuarine organisms. This study aims to determine the labile dissolved and labile particulate fractions (LPFs) of copper and zinc in the estuarine waters of a shipyard in southern Brazil under different salinity levels and in different seasons. The labile dissolved fraction was determi

6. Análise de especiação de cobre e zinco empregando voltametria de redissolução anódica com pulso diferencial
This work describes methodologies for speciation analysis of the metals copper and zinc as total, total dissolved, labile, as well as complexation capacity (conditional stability constants and available ligand concentration), using the same technique, differential pulse anodic stripping voltammetry (DPASV). Several supporting electrolytes were tested, and th

7. Estudo dos metais traço (zinco, cádmio e chumbo) em duas regiões do complexo estuarino-lagunar de Cananéia-Iguape(SP) sob diferentes pressões antrópicas / Trace metals study (zinc, cadmin and lead) in two regions of Cananéia-Iguape (SP) estuarine-lagoon system submitted to different anthropic pressures
Os setores sul e norte do complexo estuarino lagunar de Cananéia-Iguape, sujeitos a diferentes pressões antrópicas, foram estudados quanto às características hidrológicas e hidroquímicas das águas de superfície e fundo, com ênfase às concentrações de zinco, cádmio e chumbo dissolvidos. A amostragem contou com coletas espaciais e temporais, em d

9. Variação da qualidade da água do escoamento superficial de duas bacias de drenagem de Natal/RN - Brasil
The urban drainage is one of the powers of environmental sanitation and its scope is the quantitative and qualitative aspects. In decision making of managers and the engineering aspects of design are almost always taken into account only the quantitative aspects. However, the waters of the runoff have the highest concentrations of pollutants at the beginning
