  1. We recommend a drastic reduction in the use of DDT as soon as possible and that subsidies be furnished to developing countries to enable them to afford to use nonpersistent, but more expensive, pesticides and other pest control techniques. 2. In order to obtain information about the con centrations and effects of DDT in the marine en vironment, a baseline program of measurement should be initiated. This might involve taking about 1,000 samples at selected locations and ana lyzing them over the course of a year. A full-scale monitoring program should await the results of such a program. 3. We recommend greatly increased effort and support for the research and development of in tegrated pest control, combining a minimal use of October 1970 Bulletin of the Atomic Scientists 27 pesticides with maximal use of biological control. Mercury and other Toxic Heavy Metals FINDINGS Many heavy metals are highly toxic to specific life stages of a variety of organisms, especially shellfish. Most are concentrated in terrestrial and marine organisms by factors ranging from a few hundred to several hundred thousand times the concentrations in the surrounding environment. The major sources of mercury are industrial pro cesses and biocides. Although the use of mercury in biocides is relatively small, it is a direct input into the environment. There are many other pos sible routes but little data exists about the rates of release to the environment. RECOMMENDATIONS 1. Pesticidal and biocidal uses of mercury should continue to be drastically curtailed, particularly where safer less persistent substitutes can be used. 2. Industrial wastes and emissions of mercury should be controlled and recovered to the greatest extent possible, using available control and re covery methods. 3. World production, uses and waste products should be carefully monitored.
