Discover the easy kindling heart of air pollution stops fighting
Australian researcher find air pollution serious, happen suddenly heart park, fight risk to be loud. Though this research still can't prove the reason why it cause the heart to stop being fought that the air pollutant increase, but researchers imply, the government should implement stricter air quality criteria. There are " stability relations " The intersection of university and epidemiology, Monash of Australian, and prevent Daniel of department of medial science Martin the intersection of Camp and doctor and observe 8434 taking place in Melbourne between 2006 and the 2003 such as colleague The sudden heart stops fighting the case, draw the above-mentioned conclusion. Daniel and Camp waits for someone to find, the soot, dust and other air pollutant will enter the lung depths following breathing, accumulate in the human respiratory system, this death caused with heart disease or arterial occlusion has " stability connections " . Discover, can enter the lung particulate matter (PM2.5) In two days after the density increases, probability increases and keeps in above average level the heart's stopping fighting to happen. In the each air, can enter the intersection of lung and the intersection of particulate matter and every the intersection of increase and 4.26, heart park fight, take place 48 hour in the probability than the intersection of average level and high 4 percentage point. Can enter diameter of particulate matter of the lung and is less than or equal to 2.5 microns, is less than 1/20 of a stick of hair. Compared with thicker atmospheric particulate matter, can enter a foot-path of lung particulate matter small, contain a large number of poisonous harmful substances, residence time long in atmosphere, float from far, have louder impacts on health and urban air quality. Cause and effect is difficult to be broken to have studied to know before, if has already suffered from a certain respiratory system or cardiovascular vessel, it is easier for the human body to be influenced by the air pollutant. But researchers such as Daniel and Camp,etc. find, to those persons without obvious cardiovascular vessel disease symptom, the air pollutant will initiate heart disease to even result in dying suddenly too. However, Daniel and Camp says, in case of that the air pollution increases heart disease or heart and stops fighting the risk, relevant to observe appearing " The complicated result " . Because researchers have not considered observing whether the target smokes or has factor of heart disease of other initiations, this research can not prove the reason why the air pollutant is that the heart stop fighting the risk and increasing.
