There is a newly-found menace on the roads that could be harming our health - brake pads from road vehicles. Scientists have discovered that toxic dust and metal particles from worn-out brake pads could have the same harmful impact on our bodies as diesel emissions. King's College London found that fine dust released when a vehicle brakes could cause a number of health problems. These include an inflammation of the lungs, reduced immunity, an increased risk of respiratory problems, and serious infections like bronchitis or pneumonia. It is estimated that 93 per cent of particulate pollution from traffic comes from sources such as tyres, clutches and brake wear, and road dust.

近期在道路上發(fā)現(xiàn)了一種可能危害我們健康的新威脅——道路車輛的剎車片?？茖W(xué)家們發(fā)現(xiàn)磨損剎車片中的有害灰塵和金屬顆粒可能會像尾氣一樣對我們的身體造成同樣的影響。倫敦大學(xué)國王學(xué)院發(fā)現(xiàn)汽車剎車時釋放的粉塵會導(dǎo)致一系列健康問題。包括肺部炎癥、免疫力下降、呼吸系統(tǒng)疾病風(fēng)險增加以及嚴(yán)重的感染，如支氣管炎或肺炎據(jù)估計(jì)，93%的交通顆粒物污染自輪胎、離合器和剎車磨損以及道路灰塵。

The scientists say brake dust could be the cause of a condition they have dubbed "London throat". Sufferers are the city dwellers who continually experience runny noses and irritating coughs and colds. These could be caused by people inhaling the brake dust. Metal particles coat the lungs and prevent cells in our immune system from clearing harmful bacteria. Researcher Dr Ian Mudway said dust from the various sources of friction within vehicles casts doubt on motor industry claims of zero-emission cars. He said: "There is no such thing as a zero-emission vehicle. As regulations to reduce exhaust emissions kick in, the contribution from sources such as brake dust are likely to become more significant."

科學(xué)家表示，剎車揚(yáng)塵可能是導(dǎo)致“倫敦喉”的原因。其患者是那些經(jīng)常流鼻涕、咳嗽、感冒的城市居民。這些可能是由人們吸入剎車粉塵引起的。金屬顆粒覆蓋在肺部，阻止我們免疫系統(tǒng)中的細(xì)胞清除有害細(xì)菌。研究人員Ian Mudway博士稱來自汽車內(nèi)部各種摩擦源的灰塵讓人們對汽車行業(yè)宣稱的零排放汽車產(chǎn)生了懷疑。他說道：“沒有零排放這回事。隨著減少尾氣排放的法規(guī)開始生效，來自剎車粉塵等來源的影響可能會變得更加顯著。
