It has now been demonstrated that nanoparticles (generated especially in diesel exhausts but also resulting from tyre wear and the braking systems of cars) can carry carcinogens into the human brain (https://www.theguardian.com/environment/2019/nov/13/air-pollution-particles-linked-to-brain-cancer-in-new-research). This strongly suggests that this air pollution (which often exceeds legal limits in UK cities), will increase the rates of brain cancers. It is somewhat concerning that many schools in urban areas are near busy roads and problems can be exacerbated by idling cars doing the 'school run'. The brains of children may be especially vulnerable.
This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.
