But phenols are poisonous to human cells , too , and thus have to be neutralised . This is done by adding sulphate to them .
但酚类对人体细胞也是有害的,因此就需要别的物质对它们进行中和,而这可通过加入硫酸盐来完成。
One is how quickly the rapidly industrialising countries mandate the fitting of equipment that removes sulphate particles .
一是取决于迅速工业化国家强制安装硫酸盐颗粒脱除设备的进度有多快。
Injecting sulphate particles into the stratosphere , for instance , would cool the earth by reflecting more sunlight into space .
向平流层喷洒硫酸盐颗粒,可以通过反射阳光达到降低地球温度的作用。
Now and then volcanoes produce sulphate aerosols in the stratosphere which last far longer than those created by industrial pollution lower down in the atmosphere-they have lifetimes of years , rather than days or weeks .
Philip rasch , of the national centre for atmospheric research , in boulder , colorado , and his colleagues are therefore exploring the idea of deliberately polluting the stratosphere with sulphate in order to reflect solar heat back into space .
So if you were to inject a comparatively small amount of sulphate into the stratosphere while phasing out all industrial emissions lower down , dr crutzen noted in a paper published five years ago , you could keep today 's cooling levels while getting huge health benefits .
