Reported solubilities of 738 pesticide chemicals in water.

Abstract

There is no single compilation of the solubilities of pesticide chemicals in water, yet both actual and surmised solubility figures are used daily to predict or extrapolate such parameters as systemic penetration into aqueous tissues, distributions from formulations into aqueous spray carriers, transfer coefficients from residence in soils or decomposing vegetation into runoff and ground water, ease of removal from treated commodities by water rinsing, probable water contamination from direct applications or from spillage, and others. Exhaustive search of the literature by titles and by pesticides discloses that comparatively few numerically useful solubilities of pesticide chemicals in water have been recorded, however. As will be discussed later, a description of “slightly soluble” or “practically insoluble” is hardly definitive or even useful. It is hoped that the present exhaustive compilation will stimulate the production of actual solubility data, for even casual examination of the table (Table I) will disclose glaring inconsistencies and lamentable gaps in the literature commonly available to research workers and others interested in even approximate solubility data.
