...word came from Mexico City: 'Torrijos is returning." On that signal, 14 truckloads of Guardsmen roared out of a garrison at outlying Tocumen Airport. Some fanned out over the country, others sped into Panama City and pulled up at the dingy, Victorian Guardia headquarters. After a bit of harmless shooting, Sanjur and Silvera were led off to jail...
...phosphates. One possibility is a chemical called NTA which can replace a significant portion of the phosphates in a box of detergent. Even so, some experts agree that the only true solution is the construction of "tertiary" treatment sewage plants that would reduce phosphates from all sources to harmless...

Planting Fish. What could be done to clean up the mess? The mosquito abatement district switched from the persistent DDD to methyl parathion, a chemical that is effective against gnats but that deteriorates and becomes harmless in a short time. At the same time, the district hired a team of scientists from the University of California at Davis to find a way to control the gnats biologically. Led by Entomologist Sherburne F.

Like countless other chemicals, cyclamates also cause breaks in the chromosomes of both man and animals, but the genetic significance of these breaks is not yet known...
