1. Assessment of Urban Contamination by Sewage in Sediments from Ipojuca River in Caruaru City, Pernambuco, Brazil
The Ipojuca River is considered the third most polluted river in Brazil due to the intense anthropogenic activities in the surrounding urban areas. The most important effluent is sewage discharge, which is responsible for considerable contamination. Traditional analyses (infrared spectroscopy, organic matter (OM), elemental analysis and granulometry) and adv

2. Heavy metal concentrations and ecological risk assessment of the suspended sediments of a multi-contaminated Brazilian watershed
ABSTRACT. Metal concentrations in suspended sediments of one of the most polluted rivers in Brazil were measured. Concentrations of Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn were determined by inductively coupled plasma while Hg and As were analyzed with hydride generation flow injection atomic absorption spectroscopy. Contamination of As, Cd, Cr, Cu, Fe, Hg, Mn, N

3. Estudo de dinâmicas de paisagens no baixo curso do Rio Ipojuca, Pernambuco: potencial para sustentabilidade socioeconômica e cultural da região / Study of landscape dynamics in the lower course of Ipojuca river, Pernambuco: potential for the socioeconomic and cultural sustainability of the region
One of the greatest challenges in environmental planning and management is related to the need of overcoming the different regionalization forms. Since the beginnings, several are the unifying the basis efforts which allow a conciliatory limits management and space interventions. This project aims to analyze the landscape dynamics of the lower course of Ipoj

4. Modelagem da poluiÃÃo pontual e difusa: aplicaÃÃo do modelo Moneris à Bacia hidrogrÃfica do rio Ipojuca, Pernambuco
As emissÃes de poluentes e nutrientes sÃo causadoras de diversos problemas nos ecossistemas aquÃticos. O excesso de nutrientes, especificamente, o nitrogÃnio e o fÃsforo, à o principal responsÃvel pelo processo de eutrofizaÃÃo dos corpos dâÃgua. Na maioria dos paÃses desenvolvidos, grande atenÃÃo vem sendo dada à poluiÃÃo difusa, uma vez que

5. A utilizaÃÃo da microalga skeletonema costatum (greville) cleve (bacillariophyceae) na avaliaÃÃo da qualidade ambiental de Ãreas estuarinas de Pernambuco
Coastal environments are characterized by the high complexity and biological diversity, where the variety overcomes others ecosystems. The estuaries represent one of the most productive ecosystems of the world, due to the great contribution of inorganic dissolved nutritients, coming from the continent. It has been changing in the last years, as a result of a

7. A Disputa da Argila pelos ArtesÃos do Alto Do Moura â Caruaru â PE
On the formation of the earthly crust, several minerals gather and make up different kinds of rocks. Nature itself is in charge of consuming the rocks which are on the surface, by elaborating several relievo physionomies. Drainage is separated by hydrographic basins. Ipojuca river hydrographic basin, created thanks to the great failure known as Pernambucano

8. Aplicabilidade dos Testes de Toxicidade Aguda com Daphnia magna e Vibro fischeri no monitoramento da qualidade das Ãguas de bacias hidrogrÃficas: Caso do Rio Ipojuca em Pernambuco
The water quality evaluation described by the Resolution NÂ 357/05 of National Council of Environmental (CONAMA), that revoked the NÂ 20/86, established that the Environmental Agencies measured the water quality through physical, chemical, biological analysis and chronic and acute toxicities tests. By these testes is possible to know the toxic effect of su

9. Impacts of the construction of the Port of Suape on phytoplankton in the Ipojuca River estuary (Pernambuco-Brazil)
A implantação do Complexo Industrial Portuário de Suape (Pernambuco-Brasil) entre 1979 e 1984, modificou os processos ecológicos observados no estuário do rio Ipojuca. As amostras foram coletadas mensalmente em 4 estações fixas, no período de abril/86 a março/87 nas preamares e baixa-mares diurnas, utilizando-se uma rede de plâncton com abertura de
