[email protected] RESUMO: Este trabalho teve como objetivos avaliar, por meio de análises físico-químicas, polpas, sucos tropicais e néctares de goiaba e averiguar se os mesmos atendem aos Padrões de Identidade e Qualidade (PIQ) exigidos pelo Ministério da Agricultura, Pecuária e Abastecimento (MAPA). Foram analisadas três polpas, sete sucos tropicais (quatro não adoçados e três adoçados) e oito néctares (cinco convencionais e três light) quanto ao teor de sólidos solúveis (ºBrix), pH, acidez total, açúcares totais e ácido ascórbico (vitamina C). Seguindo os parâmetros determinados por lei, as polpas também foram analisadas para concentração de sólidos totais e ratio. Os dezoito produtos analisados estavam de acordo com a legislação em vigor. Palavras-chave: Psidium guajava, parâmetros físico-químicos, legislação brasileira. PHYSICAL-CHEMICAL EVALUATION AND BRAZILIAN LEGISLATION OF COMMERCIAL GUAVA PULP, TROPICAL JUICES AND NECTARS SUMMARY: This work aimed to evaluate physico-chemical guava pulps, tropical juices and nectars to ascertain whether they met the Identity and Quality Standards required by Brazilian legislation. Three pulps, seven tropical juices (four unsweetened and three sweetened) and eight nectars (five conventional and three light) were analyzed for soluble solids (ºBrix), pH, total acidity, total sugars and ascorbic acid (vitamin C). Following the parameters set by law, the pulps were also analyzed for total solids concentration and ratio. The eighteen products analyzed were in according to the legislation.

Aims: Megaprojects development has generated changes in the socioeconomic and environmental structure of several regions. This paper aims to analyse socioenvironmental changes in 10 municipalities located along the D. Pedro I - Tamoios road axis, São Paulo state, Brazil, chosen for their regional relevance, and transformations caused by the roads duplication. Study Design: Analysis on how megaprojects influence the urban structure, the environment and different social groups, focusing in Gross Domestic Product (GDP), in different productive sectors (agricultural, services and industrial), in population growth and rural and urban scenarios. Place and Duration of Study: The study was realized in São Paulo State, Brazil, during 36 months, starting in July 2015 until July 2018, and the data used and analyzed to diverse indicators were from 1950 to 2014. Methodology: Sociodemographic data, the expansion of industry, services, tourism development and agricultural production of these municipalities were collected in government databases and through field surveys. They were analysed through integrated methodologies with qualitative and quantitative approaches, based on temporal variations for the studied municipalities and for the average of São Paulo State, Brazil, with focus on social and environmental changes that took place in this study area. Results: The results indicate that an intense process of industrialisation, tourism development, urban growth and population dynamics has accompanied the recent decade’s expansion of major roads in São Paulo State, Brazil, and that these processes contribute to changes that affect natural systems and may accelerate climate changes. Conclusion: It verified that this megaproject development had not considered the sustainability of regional natural resources, in a manner that promotes environmental and living quality to the population.

In order to evaluate the environmental status within a mariculture pond, temporal variations of physico-chemical factors, protist community structure and interactions between biota and environmental conditions were investigated during a complete cycle in semi-enclosed shrimp-farming waters near Qingdao, north China. Results revealed that: (1) a total of 54 protist taxa with ten dominant species was present, comprising 4 chlorophyceans, 2 chrysophyceans, 5 cryptophyceans, 10 dinoflagellates, 3 euglenophyceans, 10 diatoms, 18 ciliates and 2 sarcodines; (2) a single peak of protist abundance occurred in October, mainly due to the chlorophyceans, diatoms and chrysophyceans, while the bimodal peaks of biomass in July and October were mainly due to the ciliates, dinoflagellates and diatoms; (3) the succession of protist communities significantly correlated with the changes of nutrients, salinity and temperature, especially phosphate, either alone or in combination with NO3; (4) species diversity and evenness indices were found to be relatively independent of physico-chemical factors, whereas species richness and the ratio of biomass to abundance were strongly correlated with water temperature and abundances of bacteria. It was concluded that planktonic protists are potentially useful bioindicators of water quality in a semi-enclosed mariculture system.
