1.   The reactor core erupted in a gigantic explosion, spewing enormous amounts of heat and disintegrated radioactive fuel into the atmosphere.

2.   And they use dirtier diesel fuel than buses, spewing massive amounts of carcinogens.

3.   The boat engines spew massive amounts of cancer-causing particulates and sulfur emissions into densely populated urban shorelines often inhabited by low-income and racially diverse constituencies.

4.   The volcano had been spewing large amounts of lava and ash since mid-July.

5.   Trains use such oils, spewing huge amounts of petroleum waste onto the ground.

6.   Underpriced energy, economists say, only worsened the problem, as economically inefficient factories spewed enormous amounts of untreated exhausts and chemical wastes into the atmosphere.

7.   This technique is considered safer and less wasteful than the traditional opencast mines, which take up a lot of space and spew huge amounts of radioactive waste.
