Food Safety Program: Endrin Monitoring In The Mississippi River, Arthur F. Novak, M. R. Ramachandra Rao
Journal of the Minnesota Academy of Science
Twelve successive monthly samplings and analyses of representative fish and shellfish and of mud and water from the lower Mississippi River showed neither a high concentration of endrin nor a time-ordered change in the concentration. The general absence of endrin from the samples indicated no significant contamination.

The Fate Of Pesticide Residues In Soil, Russell S. Adams Jr.
Journal of the Minnesota Academy of Science
Pesticidal chemicals may be lost from or inactivated in soil by volatilization, leaching, sorption, chemical' degradation, microbial decomposition, or plant removal. The persistence of o pesticide in soil depends upon the chemical nature of the pesticide and certain characteristics of the soil. Soil mineral and organic colloids sorb these compounds very tightly and restrict microbial decomposition of the pesticide. Conditions favoring microbial activity in the soil also favor the disappearance of pesticide residues. Factors that contribute to the persistence of o pesticide ore the some factors that increase its persistence.
