...years Alice Hamilton has studied the ill effects of industrial poisons (lead in the paint trades, toluene in TNT plants, carbon monoxide in steel mills, benzol in airplane "dopes"), in 1924 published a modern classic, Industrial Poisons in the U.S. She also engaged in many a bitter fight to force her scientific findings on an indifferent public...
...good Americans, we blurted it right as blunt as could be: "When is your magazine going to be published?" we shouted, looking him straight in the eye. "Oh," he replied, "we're waiting for a major victory," and with that he zoomed up the street in a cloud of carbon monoxide...
World War II is a boon to the bug armies. The minerals with which man has fought bugs for years-arsenic, copper, lead-are now needed for his war on his own kind. Carbon tetrachloride, ethylene dichloride and chloropicrin are withheld from insecticide manufacturers for the benefit of war materials. The phosphorus paste that used to kill cockroaches now goes into incendiary bombs. A group of six articles on the war against insects, in the current issue of Industrial & Engineering Chemistry, makes these facts plain...
...After years of experiment, ingenious North American Aviation has found a low-carbon, low-alloy steel suited for airplane wings, stabilizers, rudders, elevators, flaps and ailerons. Combined with a plywood fuselage, it makes a top-notch combat trainer, weighing only 3% (150 lb.) more than an aluminum ship. The aluminum saved on 1,000 steel-plywood jobs would make 420 sleek pursuit ships...
Methylene blue and purple thionine looked promising. Whereas chlorophyll combines water and carbon dioxide into glucose in the presence of light, these pigments transform ferrous sulfate [Fe (SO4)] into ferric sulfate [Fe2 (SO4)3]. The ferrous compound consists of two "ions"-a positively charged iron atom linked with a negative sulfate unit. Under the influence of these pigments and light, the ions regroup themselves into the ferric form-two positive units linked with three negative units. And in the dark this reaction reverses itself. Regrouping of the ions upsets the electrical balance of the solution, creating electrical potentials...
