Soil pollution could be a hidden cause of heart disease

Side take-away about dust (desert) in general:

> Study authors say even dust from deserts could be damaging people’s hearts when wind sweeps particles away, sending them long distances to big cities and towns. People in Japan were 21 percent more likely to end up in a hospital on days when desert dust from China and Mongolia was in the air. Pollution of air, water, and soil is responsible for at least nine million deaths each year, according to estimates.
