Denitrification in tiny anoxic pockets on sand grains could account for up to one-third of total nitrogen loss in silicate shelf sands.

Ozone pollution is a global environmental concern that not only threatens human health and crop production, but also worsens global warming. 

Forests in the Peruvian Amazon aren’t growing back after gold mining — not just because the soil is damaged from toxic metals, but because the land has been depleted of its water.
