Recent assessments have been undertaken of the health effects of long-term exposure to the air pollution mixture in the United Kingdom. This was based on studies reporting associations of mortality risk with fine particulate matter (PM2.5), which includes PM1 and PM0.1, and nitrogen dioxide (NO2), available to view at the following link:

Reviews by the Health Effects Institute and World Health Organization concluded that there is currently limited evidence on the effects on health of ultrafine particles (PM0.1). These reviews can be viewed at the following links:

Public Health England has no plans to engage in work on the effects of PM1 and PM0.1 particles on human health.
