Introduction
The physical and chemical properties of chlorpyrifos (
O, O
-diethyl
O
-3,5,
6-trichloro-2-pyridinyl phosphorothioate, CPY; CAS No. 2921-88-2) are the primary
determinants that govern fate (movement, adsorption, degradation, and catabolism)
in the environment and in biota. The uses of chlorpyrifos in locations of interest,
such as the United States in the case of this paper, are the primary determinants of
the entry of chlorpyrifos into the environment and its subsequent fate in the regions
of use and beyond. The uses and manner of use are addressed in this paper.
The data on physical and chemical properties provided here were the basis for
modeling long range transport and assessing bioaccumulation (Mackay et al.
2014
),
characterizing routes of exposure to chlorpyrifos in terrestrial systems such as soil,
