摘要: Abstract Background Studying the physiologic effects of components fine particulate mass (PM 2.5 ) could contribute to a better understanding nature toxicity air pollution. Objectives We examined relation between acute changes in cardiovascular and respiratory function, PM -associated-metals. Methods Using generalized linear mixed models, daily ambient -associated metals were compared measures 59 healthy subjects who spent 5-days near steel plant on college campus. Results Interquartile increases calcium, cadmium, lead, strontium, tin, vanadium zinc associated with statistically significant heart rate 1–3 beats per minute, 1–3 mmHg blood pressure and/or lung function decreases up 4% for total capacity. Conclusion Metals contained found be physiology.
