Is there any evidence (study) which shows correlation with city air to allergy (to anything) or any other breath health problems?
If yes is this correlation different if someone lives in big city next to the big water (New York, LA, Chicago)?
PS. Some link to research paper will be helpful. When searching the Internet I only found:
Rodriguez, M. G., Rivera, B. H., Heredia, M. R., Heredia, B. R., & Segovia, R. G. (2019). A study of dust airborne particles collected by vehicular traffic from the atmosphere of southern megalopolis Mexico City. Environmental Systems Research, 8(1), 16. https://doi.org/10.1186/s40068-019-0143-3
Pollen in cities besides being a typical allergen (Kiotseridis et al. 2013) found in the air could also impact health in other ways as it adheres and retains both fine particles and agglomerates.
