“…Moreover, the drying up of rivers may also lead to food shortage [4]. Meanwhile, rapid urbanization and intensive anthropogenic activities have already brought and will bring a series of water pollution to rivers around the world [5,6]. Therefore, the influences of these water pollutions should be systematically evaluated.…”

This study was performed in the Linshui River Watershed to explore the contents of heavy metals in river water, their species, and health risks. The test results show that the contents of arsenic (As), chromium (Cr), copper (Cu), uranium (U), and thorium (Th) are relatively low and below the limit of class III of the environmental quality standards for surface water. According to the analysis through PHREEQC (version 2.18), the main species of As, Cr, Cu, U, and Th are H

“…In addition, these streams are especially contaminated with faecal coliforms, exceeding by 196 fold the maximum concentration allowed by local regulations (Conselho Nacional de Meio Ambiente ‐ CONAMA, 2000). This high coliform concentration likely results from the discharge of raw sewage because of the poor sewer infrastructure (Borges, Santos, Caldas, & Lapa, 2015).…”

1. Alien species often flourish and become invasive in urban ecosystems. How and why invaders succeed in urban systems is an important, yet poorly understood, question. We investigate whether the success of urban invaders is related to changes in species traits that enhance invasive potential.

“…The water quality parameters were determined using the methodology described in Borges et al (2015). Once georeferenced according to its coordinates in the sampling stations of INEA, these data were converted in vector format of points and interpolated with the technique Inverse Distance Weighted (IDW), available in the ArcGIS 10 software (ESRI, 2011).…”

As well as other sub-basins of the Guanabara Bay, the Canal do Cunha watershed, located in the Rio de Janeiro city, has suffered severe environmental degradation since the 50s, due to accelerated urban-industrial development. The fluvial dynamics has changed by the deforestation, landfill constructions, drainage and vale occupation. Canal do Cunha deliver wastewaters and sediments at the western side of Guanabara Bay. Contribute to the environmental degradation and has direct influence on the water quality indexes and heavy metal contamination at the western side of Guanabara Bay. This study intends to evaluate, through geoprocessing techniques, the spatial distribution of Lead (Pb), Zinc (Zn), dissolved oxygen (DO) and total phosphorus (total P) concentrations and pH values, using data provided by six monitoring stations of the Instituto Estadual do Ambiente-INEA (State Environmental Institute). This work allows to observe the influence of weather conditions on Pb and Zn concentrations in superficial waters and surface sediments and the behavior of DO, pH and total P of superficial waters before and after the implementation of the remediation program: Programa de Despoluição da Baía de Guanabara (PDBG; Pollution Remediation Program of Guanabara Bay). Canal do Cunha flow has direct influence on the low quality indexes of water and contributes to the heavy metal contamination and environmental degradation of the western region of Guanabara Bay.
