Vie have however retained it in use since during hot weather it provides more comfortable working con ditions for the operators though contributing little to the dispersal of tetraethyl lead vapours.

In May of 1959, the preliminary experiment involving the use of tetrainethyllead was initiated In San Francisco, California and was completed some months later, as described in detail In a Report of the Kettering Laboratory, dated November 10, 1959 and entitled "An Investigation of the Potential Hazards of Exposure to Lead Associated with the Handling and Use of Gasoline Containing an .Antiknock Fluid in Which Tetramethyl lead is Substituted for Tetraethyl Lead."
