The Queensland government in Australia has suspended blasting operations at a coal mineĀ  accused of having caused toxic gases to fall on a residential neighbourhood. Not only do these gases pose major health threats to communities living close to mines, nitrous oxides (NOx) are the fourth largest contributor to greenhouse gas emissions, as well as being responsible for the formation of acid rain. One of the companies whose operations are affected is Anglo American.
