Fedak KM, et al. - Researchers determined the acute impacts of exposure to air pollution emissions from cookstove technologies on blood pressure in a controlled human-exposure study- the Subclinical Tests on Volunteers Exposed to Smoke Study. Participants were 48 healthy adults who were exposed to 5 cookstove treatments (three stone fire, rocket elbow, fan rocket elbow, gasifier, and liquefied petroleum gas) for 2 hours, spanning PM_2.5 (ambient fine particulate matter) levels from 10 to 500 μg/m³, and a filtered air control (0 μg/m³). For the three stone fire treatment vs the control, a lower systolic pressure was noted 30 minutes post-exposure; the reported systolic pressure was suggestively lower for the gasifier. According to the findings, an increase in systolic pressure could be seen within 24 hours of short-term exposure to air pollution from cookstoves. The occurrence of this response was noted across a range of stove types and PM_2.5 levels, implying that cardiovascular health may be adversely influenced by even low-level exposures to cookstove air pollution.
