Use cosmetics in emissions PM2 also every day. 5?

Yesterday, the 'clean air' in Shanghai jiaotong university science and technology innovation on the BBS, experts say that in addition to soot emissions, barbecue, etc, from paint coating, deodorant, camphor ball to cosmetics, a variety of life pollution have become PM. One source of fine particulate matter. According to introducing, PM. Is often the formation and growth of various pollutants in the atmospheric environment, including the proliferation of new particle generation and particle grew up. Once new particles generated, easily with other new particles touch and become a larger particle size of particulate matter. Shanghai jiaotong university environmental science and engineering college jin-ping cheng, said professor PM at present. Pollutants sort very much, basically have sulfate from sulfur dioxide, nitrogen oxides such as nitrate, and a volatile organic pollutants, etc. Environment institute professor Cindy said, cosmetics and other personal care products contain more volatile and semi volatile organic compounds, and some additives, such as musk compounds. People of this new type of pollutant has but they are used by a lot of, directly into the air, or into the water after washing and so on link; The existing conventional water treatment and air purification, or not to be removed, so they have potential environmental hazards, or even can pass environmental circulation to return to the body. Compared to industrial and mining, agriculture, transportation, construction, etc. , it's very difficult to measure and monitor these sources. Expert estimates, days of winter more than summer haze pollution is little, but June straw burning also easy into a haze of surrounding area. Cindy said, as a result of facing the traditional pollutants and complicated situation of new pollutants coexist, cannot ignore individual 'contribution' in atmospheric environmental pollutants. In the control of major pollution sources at the same time, should with green life against health risks. Editor: huang rui
