There is much epidemiological evidence that levels of respirable air particles in urban areas are a significant risk to respiratory and cardiovascular health. Current air quality standards address this but recent evidence indicates that the smallest particles(nanoparticles) may be particularly damaging and these are not measured or regulated .Their primary source is motor vehicle exhaust but whether it is their size, number, surface area or chemical constituents which present the risk is currently unknown.

Breathing is bad for your Health

 If the influence of these parameters on the relevant biological pathways of effect was understood then it would inform suitable environmental control measures to protect the Public Health.

In addition to this man-made environmental health risk there is a potential risk to patients with asthma from the ubiquitous presence of fungi and possibly protozoa in air. Until recently the lungs were believed to be sterile except for periods of respiratory infection. It is now recognised that the lungs support their own ‘microbiome’ but the effects of environmental fungi and protozoa on this microbiome is currently under researched.
