Herder During a Storm in China

The sand storms originate in the arid and semi-arid areas of northwest China and Central Asia. Strong winds carry sand and dust into the north and east of China, damaging the health of both people and livestock, and hurting industrial and agricultural production.

Coal ash that has been dumped in disposal sites without first being properly handled is easily whipped up into the atmosphere by strong winds, mixing into dust storm and traveling thousands of kilometres. But even more worrying is that this coal ash contains a high concentration of heavy metals and other toxic pollutants, including arsenic, selenium, lead and mercury. The presence of coal ash has transformed the physical and chemical composition of dust storms which now pose a serious threat to people’s health.
