Cyanobacteria toxicity: potential public health impact in South Portugal populations.

A planner's perspective on the health impacts of urban settings.

The profession of town planning originated out of concerns for the health and well-being of people. Progress was made as crowded and unsanitary inner city slums were replaced with suburban environments where individuals could access green open spaces and clean air. With significant increases in urban populations and the geographic spread of the city, over time these environments became increasi...

Toxicity assessment of crude and partially purified extracts of marine Synechocystis and Synechococcus cyanobacterial strains in marine invertebrates.

Among the Cyanoprokaryota, the genera Synechocystis and Synechococcus have rarely been studied with respect to potential toxicity. This is particularly true with marine environments where studies about the toxicity of cyanobacteria are restricted to filamentous forms at the warmer temperate and tropical regions and also to filamentous forms at cold seas such as the Baltic Sea. In this study, we...

Health Risk Assessment of Cyanobacterial (Blue-green Algal) Toxins in Drinking Water

Cyanobacterial toxins have caused human poisoning in the Americas, Europe and Australia. There is accumulating evidence that they are present in treated drinking water supplies when cyanobacterial blooms occur in source waters. With increased population pressure and depleted groundwater reserves, surface water is becoming more used as a raw water source, both from rivers and lakes/reservoirs. A...

A Review of Nanoparticles Toxicity and Their Routes of Exposures

       The new scientific innovation of engineering nanoparticles (NPs) at the atomic scale (diameter<100nm) has led to numerous novel and useful wide applications in electronics, chemicals, environmental protection, medical imaging, disease diagnoses, drug delivery, cancer treatment, gene therapy, etc.. The manufactures and consumers of the nanoparticles-related industrial products, however, a...
