Urban benzene and population exposure: People arn't just at risk from carcinogenic benzene when they are out on city streets

Article Abstract:

Benzene pollution from motor traffic can cause leukaemia, but risk estimates cannot just be estimated from environmental concentrations of benzene. A new sampling device, depending on the diffusion of gas molecules due to concentration gradients over a diffusive barrier, has been used to monitor benzene pollution in Antwerp, Athens, Murcia, Padua, Rouen and Copenhagen. Pollution indoors may be due to benzene entering from the outside, and was generally higher than outdoors, possibly due to imbalances between flow of pollutant and its removal to outside.

Mine waste pollutes Mediterranean

Article Abstract:

The southwest Mediterranean coastline is seriously polluted with contaminants from the region's mining industry. Worryingly, an assessment of how toxic waste in Spain, Algeria, Tunisia and Morocco is affecting the environment has not yet been established although smaller, specific incidents of pollution have been considered. One of the most highly polluted areas in the region is Portman Bay in Spain. Immediate action should be taken to monitor the situation and halt the environmental damage.

Co-carcinogenic effect of Beta-carotene

Article Abstract:

The hypothesis that beta-carotene can prevent cancer in humans is supported by epidemiological and animal studies on vitamin A and its analogues. However chemoprevention trials have show than beta-carotene can actually increase incidences of lung-cancer and mortality in heavy smokers and asbestos workers. Beta-carotene in rat lung was found to boost phase I carcinogen-bioactivating enzymes, including polycyclic aromatic hydrocarbon activators, associated with oxidative stress.
