Trilithium resin

Trilithium resin was a highly toxic waste product that was produced by the engines of Starfleet vessels in the 24th century. A volatile substance, trilithium resin was highly sought after for use as a powerful explosive. Storing and moving it was a highly delicate process and required specialized equipment.

In 2369, a group of weapons dealers led by Kelsey attempted to steal trilithium resin from the warp core of the USS Enterprise (NCC-1701-D) while it was undergoing a baryon sweep at Arkaria Base. They were stopped by Captain Jean-Luc Picard.

When introduced into an atmosphere, trilithium resin acts as a biogenic weapon and is lethal to Humans (but not Cardassians). Two hundred kilograms of trilithium resin is enough to make a planet uninhabitable to Humans for fifty years. Captain Benjamin Sisko poisoned the atmosphere of Solosos III with trilithium resin in 2373 in response to Michael Eddington's use of cobalt diselenide.
