PM2.5 generate higher carcinogenic substances mixed with sand
China's traditional Chinese medicine to
Atmospheric pollutants fine particulate matter (PM2.5) has serious harm to human body health, researchers in Japan on April 28, was held in kumamoto of Japan society meeting, if PM2.5 and sand together, also generates higher carcinogenic substance.
Early kanazawa university department of pharmacy, a professor at sichuan and a led the research team noted that each spring dust weather, carcinogenicity in PM2.5 very high called "NPAH" (nitro polycyclic aromatic hydrocarbons) substance concentration becomes high.
The team to join in the container in the atmosphere of nitrogen oxides and PM2.5 contain "PAH" aromatic hydrocarbons (pahs), then adding sand to the container, and spread the sand in the container, make fully mixing, both found in these conditions, "PAH" changes to "NPAH".
PAH (polycyclic aromatic hydrocarbons) is a molecule contains two or more benzene hydrocarbons, oil heating will produce polycyclic aromatic hydrocarbons, polycyclic aromatic hydrocarbons, which belongs to the persistent organic pollutants (pops), has been the international cancer research center as a carcinogen. And nitro polycyclic aromatic hydrocarbons are polycyclic aromatic hydrocarbons, carbon ring formed by one or more hydrogen atoms replaced by nitro an organic compound, is a kind of strong mutagenic and carcinogenic substance.
The research team, points out that many researchers have found that in the experiment the carcinogenicity of NPAH is more than 100 times higher than PAH. Before April, often appear to PM2.5 observed and sand weather at the same time, it is necessary to pay more attention to.
Early chuan and a pointed out that the experiments have shown that aim for composite effects of PM2.5 and sand countermeasures is very important. In a large number of PM2.5 observed at the same time and period of yellow sand, should pay attention to wear can cause shielding PM2.5 mask. (LanJianZhong)
