12.2 Persistence and degradability
AEROBIC: Degradation of ethephon occurs with a half-life of 7.5 days in sandy loam soil when incubated in the dark at 25°C. The major degradates were ethylene gas and soil bound 2-hydroxy ethyl phosphonic acid. Only 4.7 percent of 14C-radiolabeled ethephon was remaining after 30 days(1).
12.3 Bioaccumulative potential
An estimated BCF of 3.2 was calculated for ethephon(SRC), using a measured log Kow of -0.22(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
The Koc of ethephon ranges from 608 to 8547 determined from adsorption/desorption experiments(1). 14C-Ethephon in solution at 0.4, 1.3, 5.1, and 10.1 ppm and applied to loamy sand, silt loam soil, sandy loam and clay soils as well as in sandy loam pond sediments was equilibrated in the dark for 24 hours at 25°C. Freundlich adsorption values were 2.4 for the silt loam soil, 7.2 for the loamy sand soil, 29.8 for sandy loam soil, 53.1 for the clay soil, and 57.3 for the sandy loam pond sediment; respective K values were 608, 3117, 4078, 3220, and 1676. Freundlich desorption values were 3.9 for the silt loam soil, 17.5 for the loamy sand soil, 62.4 for sandy loam soil, 69.0 for the clay soil, and 87.9 for the sandy loam pond sediment; respective K values were 992, 7600, 8547, 4181, and 2570(1). According to a classification scheme(2), this range of Koc values suggests that ethephon is expected to have a low to slight mobility in most soil types but also suggest that it could be immobile in a few soil types. The pKa1of 2.5 and pKa2 of 7.2 indicates that this compound will exist entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(3).
12.5 Other adverse effects
no data available
13.Disposal considerations
13.1 Disposal methods
Product
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packaging
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
