It is not remarkable that. No lead chromate was found in the alimentary tract, since the children vomited a great deal and thus threw up all of the poison.

Excerpt from Insecticide Studies: I, Pyrethrum Powders Containing Poisonous Metals; II, a Compilation of Analyses of Insecticides and Fungicides; III, State Laws Governing the Composition and Sale Insecticides

In the course of a recent examination of a large number of miscellaneous insecticides it was observed that a number of pyrethrum powders contained lead chromate. Those powders arc sold under such names as Persian Insect Powder, Dalmatian Insect Powder, Buhach, and Pyrethrum, and are colored yellow because there seems to be a popular demand for this grade of goods, the public apparently believing that the preparation must he bright yellow in order to kill insects. As a matter of fact pure pyrethrum, which is composed of the ground flower heads of Pyrethrum roseum and Pyrethrum cinerariæsfolium usually possesses a light yellow color, but never the brio-ht. intense yellow color given to it by lead chromate.

As lead chromate is known to be poisonous, it would appear that it i a very reprehensible practice to add it to pyrethrum powders, since they are often blown about living rooms with a bellows to kill insects, and are consequently inhaled by human beings. Besides this, pyrethrum is always advertised to be harmless to human beings, which it is when pure, but ceases to be so when it has been mixed with lead chromate or other yellow colored chromates. In view of the above facts it was deemed advisable to examine the pyrethrum powders sold upon the American market to discover which of them contain yellow chromates and at the same time to cite eases of poisoning by chromates to substantiate the claim that any of the yellow chromates that might be used for this purpose, and especially lead chromato. are poisonous to human beings. The facts which have been collected on these points are embodied in the following report:

Cases Of Poisoning By Lead And Other Chromates.

Since it is not generally known that many pyrethrum powders contain lead chromate, it doubtless often happens that physicians are much puzzled as to the cause of the illness of persons who have been exposed to the action of such powders.
