復(fù)旦教授：“霧霾使鮮肺6天變黑”報道不實(shí)(圖)

“太恐怖，霧霾能使鮮紅色的肺6天就變黑，若形成黑肺，逆轉(zhuǎn)幾無可能。”昨天，一則觸目驚心的新聞在網(wǎng)上引發(fā)熱議，這讓談PM2.5色變的公眾又一次陷入恐慌。昨天下午，該報道中的項(xiàng)目負(fù)責(zé)人、復(fù)旦大學(xué)公共衛(wèi)生學(xué)院環(huán)境衛(wèi)生教研室主任、博士生導(dǎo)師宋偉民教授對新京報記者稱，該報道中的描述與事實(shí)不符，其本人沒有接受過相關(guān)采訪，也從未說過“若形成黑肺，逆轉(zhuǎn)幾無可能”的言論。[查看全文]

(ECNS) -- News broke Monday of an experiment that had turned a rat's lungs black by exposing it to polluted air, but a professor who led the experiment has since denied it as a rumor, according to the Beijing News.

The report by China Radio International (CNR) cited an experiment conducted at Fudan University. Researchers had allegedly found that a rat's lungs were heavily blackened by PM2.5 after the animal had been exposed to heavily polluted air for six days.

The report also provided shocking photo comparisons of the blackened and normal lungs.

But Song Weiming, the leading professor in the experiment, told the Beijing News that the CNR report was not consistent with his experiment.

"We took normal lungs from a healthy rat, then soaked them in a liquid containing PM2.5 particles for six days," Song said.

Song added that the lungs showed signs of turning black, but that the intensity of PM2.5 in the liquid was thousands of times higher than the air we breathe.

Song also said he did the experiment to investigate whether some medicines have the effect of moistening the lungs. He also denied having said in the report that "once lungs are blackened, it can't be reversed."

Fudan University said it would release a complete report later.

Pan Xiaochuan, an expert on public health at Peking University, said the experiment on rats can't be applied to humans.
