Many studies have linked airborne illnesses to density and nearness of gas wells, some documenting problems up to 4km from wells.  Because airborne pollution can be inhaled, swallowed, and also reach the skin, it has emerged as one of the primary public health concerns.  Other shale gas chemicals have created ground-level ozone over 300 km from the source, aggravating asthma, respiratory diseases and causing irreparable lung damage.
