Concentrations of propoxur in air following repeated indoor applications.

The insecticide propoxur was applied as 2 non-overlapping bands approximately 1 m wide to the interior of houses in El Salvador once every 35 days for a period of 9 months. Air samples were collected from the interior of the houses once every seventh day during the entire period. In the study area, air temperatures remain relatively constant, while rainfall varies seasonally. It was found that volatilization of propoxur, as determined by the amounts detectable in air, represented release of the chemical from the treated surface and that the volatilization process was most influenced by the amount of moisture present in the air. Higher air concentrations of propoxur occurred during periods of high relative humidity than in periods of low relative humidity. The principles involved in this process and its bearing on the value of propoxur in malaria control programmes are discussed.

Hydatid disease is endemic in California.

Hydatid disease, a parasitic infection of global importance and a condition for which there is no known medical treatment, is established endemically in the Central Valley of California. Only further study will reveal whether or not the infection is now spreading or intensifying or is remaining fairly stable at a relatively low level of endemicity. California physicians should be aware of its presence and the fact that in most sheep-raising areas of the world it constitutes a problem of major medical and public health importance. Although a number of national or regional programs for hydatid disease control have been undertaken, clear progress has been evident only in Iceland, in New Zealand and in the Australian state of Tasmania.(2,4,5)
