As explained in Section 5.2.3, p,p -DDE is much more persistent in food chains than either p,p -DDT or p,p -DDD, and dnring the 1960s when DDT was still extensively used, it was often the most abundant of the three compounds in birds and mammals found or sampled in the field. Since the widespread banning of DDT, very little of the pesticides has been released into the environment, and p,p -DDE is by far the most abnndant DDT residue found in biota. While discussing the ecological effects of DDT and related compounds, effects on population numbers will be considered before those on popnlation genetics (gene frequencies). 

The distribution of DDT and related compounds in fish suggests that they can convert DDT to DDD and DDE, which has been confirmed by studies in which fish of... 

The above discussion has been based upon the assumption that aqueous and micellar pseudophases are distinct reaction media, i.e. a reactant in water does not attack a micellar-bound reactant. Recently this view has been challenged by Nome and coworkers who have shown that rate constants for attack of OH- upon hydrophobic organic chlorides, such as DDT and related compounds (10), have the predicted dependence upon [surfactant] or...

Insecticidal activity of DDT and related compounds is due to their neuroexcitatory effect, the mechanism of which is very similar to that of pyrethroids 75). Using a number of analogs of DDT (34), DDD (35), and prolan (36), p,p -substituents of which are modified variously as well as those of methoxychlor (37), the trichloro-...

Saponification has been by far the most commonly used method for both the identification and, in many instances, quantitation of DDT and related compounds. Derivative techniques have been applied to biologi-... 

With respect to the described results a significant contamination of sediment samples of the Teltow Canal, Berlin (Germany) with DDT and related compounds was pointed out for a longer time period. Considering the sedimentation rate and y-spectrometric dating formerly applied to a comparable sediment core (unpublished results, M. Ricking) a geochronological description of the DDT related emissions into the sediments of Teltow Canal is enabled. 

Although DDT and related compounds are no longer used as insecticides in North America, they continue to be manufactured here for foreign markets. Exposure to such compounds causes CNS excitation, not pulmonary dysfunction. The answer is (E). 

This review summarizes some of the proposed products and pathways of the anaerobic degradation of the chlorinated hydrocarbon pesticides. Some aerobic work is included because the organisms studied existed anaerobically in the environment. The most work has been conducted with DDT and related compounds. There is some information on dieldrin with less on endrin and lindane. The other chlorinated hydrocarbons have received little attention. 

Most studies of the anaerobic degradation of chlorinated hydrocarbons have been carried out with DDT and related compounds. Various microorganisms were studied either as pure cultures or as mixed cultures from environmental sources. In appropriate cases the organisms were studied under anaerobic and aerobic conditions. In many cases the two conditions yielded similar end products.
