Investigação da poluição por metais tóxicos no córrego do Cintra

Cintra stream is the major receiver of treated effluent from sanitary, hospital and research laboratory sewage from the UNESP campus in Botucatu, Rubião Júnior District, São Paulo state; and it has shown evidence of diffuse contamination by metals along it. Analyses of the most toxic metals (Pb, Cu, Fe, Ni and Zn) were carried out by using an atomic absorption spectrometer AA-6.800 - Perkin Elmer, analyst 700. ANOVA followed by the Tukey test were used for data analyses at 5% significance level. The main objective of this study was to compare current data on metal levels with data from other studies, in the same area, and of the same nature, conducted before and after implementation of chemical residue management by the university in 2008. Also, it aimed at identifying and quantifying possible diffuse and punctual contamination. Sites S1 and S2 showed punctual contamination, while diffuse sources were observed between S4 and S5. The quality of water in the Cintra Stream improved after establishment of the program of laboratory chemical residue management in the Campus of UNESP.

Estudo sobre o uso de agregados reciclados na composição de concretos e argamassas

Two of the major problems caused by construction activity are the production of construction and demolition waste (CDW) and the exploitation of mineral resources, causing big impacts on the environment. Therefore, the recycling has been shown as an alternative to mitigate the harmful effects of waste on the urban environment and prevent the exploitation of new raw materials. This course work aims to study the behavior of recycled aggregates from Vale do Paraíba in concrete and mortar. Initially, it presents the definitions of recycled aggregates according to CONAMA Resolution No. 307/2002, the aggregate settings for concrete and mortar (such as the grain size, its origin and density, and the characterization parameters according to ABNT), and the definition of ACI method of concrete mix design. Afterwards, it presents the characterization of materials separated by assays. After that, it shows the theoretical concrete proportioning applying the ACI method and experimental concrete proportioning. Then, the analysis of results is performed to finally conclude that the materials provided can't be used to replace natural aggregates because they cannot have the same performance. With the studies, it could be observed that the recycled aggregate presents a great complexity and diversity in origin, therefore the form how the material should be handled requires great care
