The purpose of these experiments was to determine the movement and accumulation of mirex that is representative of what occurs in the natural environment. Data derived from analyzing uptake and effects of pesticides are no more reliable than the success of attempts to duplicate natural field conditions. For example, if the mirex is introduced into water via carrier or solubilizer, synergistic or antagonistic effects cannot be discerned by the use of a carrier control. Since physico-chemical interaction between solubilizers and pesticides affects surface phenomena of the insoluble pesticide, transport across the first physiological barrier, the cell membrane, may also be affected. These interactions need not be defined, however, when using mirex leached from mirex bait (1.40 kg/ha) since this simulates what would occur in the environment. The only drawback to using such a leachate is the absence of precise control of mirex concentrations in the water.
