Transcript Page 4. In order to more fully investigate the danger from pesticide pollution, several species of fish and birds have also been examined. This examination has sometimes consisted of whole body analysis. Animals are frequently dissected and the various body organs analyzed separately. When body organs are separately analyzed a whole new picture emerges. One sample of mullet contained 1 .149 ppm of DDT and its metabolites in the liver, .76 ppm in the gonads, 16 ppm in the brain, and .346 ppm in the body flesh. Had this been prepared as a whole body sample, the residue level would have been misleading. This tissue or organ concentration causes much concern among biologists. Random sampling results revealed that speckled sea trout had high concentrations in the liver and gonads, and some bird samples have contained extremely high pesticide residues. A peregrine falcon found dead on Padre Island contained 8.4 ppm of DDT residue in the brain and 56 ppm in the liver. Another bird, a white pelican, found dead near Corpus Christi, contained 84 ppm of DDT in the body flesh; 120 ppm in the liver; 18 ppm in the brain; 31 ppm in the heart; and 16 ppm in the kidney. In addition, this same bird had over 2 ppm of Dieldrin in most body tissues and 1 15 ppm and 1 14 ppm of polychlorinated biphenyl compounds in the body flesh and liver, respectively. The residues of DDT found in analysis of sea trout ovaries or eggs have ranged as high as 7.98 ppm. Liver from this species has contained as high as 9.3 ppm of DDT residue. Evaluation of the data being amassed in this study indicates that the impairment of reproductive ability and decrease in the survival of young are the greatest dangers to a species at the present time. One researcher found that a species of fresh water trout fry hatching from eggs that contained 2.95 ppm or more of DDT would not survive. Another study has shown that one of the metabolites of DDT, DDE, has caused a change in the matabolism in birds that results in their inability to produce firm eggshells. The result is thin or non-existent eggshells and a marked increase in egg mortality before hatching can occur. Evidence from data now being examined indicates that levels of DDT and other persistent pesticides are high enough that, in some species and in some bay areas, significant but undetected increases in mortality have occured somewhere between the time the egg was fertilized through the first few weeks of life.
