考研英语外刊：通过食物、水和呼吸摄入微塑料，对人体健康产生影响

Scientists do not know what happens when microplastics are inhaled, but the new study speculates that “most inhaled particles will be ingested” rather than coughed or sneezed out. The researchers also estimated that microplastic particles settling on to a single meal per day could add a further tens of thousands to the annual amount consumed.

Cox was clear that there are no known health effects as yet, but he said the ingested particles are “a high exposure risk in terms of numbers. It could be a potential alarm call for sure”.
