Objective: To understand the effects of airborne pollution on cardiopulmonary function in healthy person.
Methods: 15 healthy workers were selected from heavily polluted area as the experimental group (EG) and 15 healthy workers were selected from relatively clean area as control group (CG). The blood pressure were measured with sphygmomanometer and the vital capacity (VC) were detected with FHL-II type spirometer at rest status. Cardiopulmonary functions in different exercise states were measured by using the cardiopulmonary exercise testing (CPET).
Results: It showed that heart rate of EG was more higher than those of the CG at rest status (P < 0.01), and VC was more lower than those of the CG (P < 0.05). While the load increased to AT, the results of VO2, VO2/kg, O2P and METS in CG were more higher than these indexes in EG (P < 0.05, P < 0.01) . While the load increased to VO2 max, the results of VO2 max, VO2 max/kg, O2P, METS and DT in CG were more higher than these indexes in EG (P < 0.01), and the recovery of heart rate in EG was slow in comparison with CG.
Conclusion: Airborne pollution could have adverse effects on the cardiopulmonary function, reserve ability and function potential. The chronic adverse effects of airborne pollution on the health could be easy to reflect at static state. Therefore CPET could roundly evaluate the damage of airborne pollution to cardiorespiratory function.

In this study we monitored exposure to airborne dust in workers performing various tasks at two biomass-fuelled thermal power plants (27 and 46 MW) over six years. The plants are mainly fuelled by forest wood chips and, to a lesser extent, by agro-food products, with annual consumption of about 300 and 450 kt. We focused on inhalable wood dust because of its potential carcinogenicity to humans.

Phthalate acid esters (PAEs) and bisphenol A (BPA) are recognized as common endocrine disruptors associated with various adverse effects on human health. However, limitations in existing systematic studies, particularly in air detection, have raised concerns about potential health risks from inhalation exposure. In this study, PM samples were collected in Dongying, a petrochemical city, from October 27 to December 6, 2021.

Background: Insufficient evidence is available to confirm the effect of exposure to airborne metals on mental disorders, particularly among asthmatics. We aimed to investigate the effect of airborne metal exposure on mental health responses in asthmatics and the general population.
Methods: Using nationally representative cross-sectional data, a total of 47,796 adults were analyzed.
