324.8307f Information requirements. Sec. 8307f. (1) Upon the director's request, a person who has registered a pesticide shall provide the information necessary to determine its mobility in the environment and its potential to contaminate groundwater. This information may include any of the following: (a) Water solubility. (b) Vapor pressure. (c) Octanol-water partition coefficient. (d) Soil absorption coefficient. (e) Henry's law constant. (f) Dissipation studies including the rate of hydrolysis, photolysis, or aerobic or anaerobic soil metabolism. (g) Product formulation. (h) Other information considered necessary by the director. (2) Information requested under subsection (1) shall be consistent with product registration information required under FIFRA. (3) As used in this section: (a) 'Aerobic soil metabolism' means chemical degradation in soil in the presence of oxygen. (b) 'Anaerobic soil metabolism' means chemical degradation in soil in the absence of oxygen. (c) 'Henry's law constant' means the ratio of the partial pressure of a compound in air to the concentration of the compound in water at a given temperature.

adation in soil in the absence of oxygen. (c) 'Henry's law constant' means the ratio of the partial pressure of a compound in air to the concentration of the compound in water at a given temperature. (d) 'Hydrolysis' means a chemical reaction in which water combines with and splits the original chemical creating degradation products. (e) 'Octanol-water partition coefficient' means the ratio of a chemical's concentration in the water-saturated octanol phase to the chemical's concentration in the octanol-saturated water phase. (f) 'Photolysis' means a chemical reaction in which light or radiant energy serves to split the original compound creating degradation products. (g) 'Soil absorption coefficient' means the ratio of absorbed chemical per unit weight of soil or organic carbon to the aqueous solute concentration. (h) 'Vapor pressure' means the pressure exerted by the vapor of a substance when it is under equilibrium conditions. (i) 'Water solubility' means the maximum amount of a material that can be dissolved in water to give a stable solution. History: Add. 2002, Act 418, Imd. Eff.
