On February 22, 2014, NASA announced a greatly upgraded database[1][2] for detecting and monitoring PAHs, including 2-methylnaphthalene, in the universe. According to NASA scientists, over 20% of the carbon in the universe may be associated with PAHs, possible starting materials for the formation of life.[1] PAHs seem to have been formed shortly after the Big Bang, are abundant in the universe,[3][4][5] and are associated with new stars and exoplanets.[1]

Several enzymes biodegrade 2-methyhlnaphthalene in anaerobic conditions.[6][7]
