Persistence and degradability

AEROBIC: Mecoprop is decomposed in soil by microbial degradation(1). The estimated half-lives of 14C-ring-labeled mecoprop (2 ppm) in a sandy loam soil at 50% water holding capacity at 20, 10 and 5 deg C was 3, 12, and 20 days, respectively. In dry and flooded soil (25% and 200% of water holding capacity) at 20 deg C, the half-lives increased to 10 and 15 days, respectively. The half-life decreased by 43% when the concentration of mecoprop was decreased by a factor of 10. Comparing the half-lives of mecoprop in surface soil and subsurface soil, the investigators found half-lives of mecoprop in an undisturbed soil column of a coarse sandy soil to be 7 days at 0-33 cm depth, 70 days at 33-66 cm depth and 34 days at 66-99 cm depth. In these experiments when half of the mecoprop had disappeared, 12% of the 14C was recovered as CO2 and when 90% of the mecoprop had disappeared, 50% of the 14C was evolved as CO2. The degradation intermediates were not identified(1). Using UV absorption, HPLC, GC-MS and other techniques to monitor the course of mecoprop biodegradation using enriched mixed culture from a soil sample, found that biodegradation was incomplete (75%) and that 4-chloro-2-methylphenol was an intermediate(2). GC-MS data also suggested that other phenolic compounds with repositioned chloro and methyl groups are formed(2). The half-lives of mecoprop in clay loam, heavy clay loam, and sandy loam soils at 20 deg C and 85% field moisture capacity were 9, 8, and 7 days, respectively(3). An earlier experiment in which the UV absorption was used to monitor the disappearance of mecoprop (50-80 ppm) with an inoculum of Mardin silt loam, Honeoye silt loam and Dunkirk silt loam; 100% degradation, as typified by the loss of the aromatic ring, was not completely obtained in 47, 124, and 205 days, respectively when incubated at 30 deg C and pH 7.2(4). Using undisturbed soil core techniques and different applications of 14C-ring labeled mecoprop, biodegradation studies were performed resulting in 14.2 to 25.07% 14CO2 evolution over the 90 day study period(5). Under aerobic conditions, (S)-mecoprop degrades faster than (R)-mecoprop(6).

Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for mecoprop(SRC), using a log Kow of 3.20(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).

Mobility in soil

The soil distribution coefficient for mecoprop in three Danish agricultural soils were: sandy loam (pH 6.9), 0.12; sandy loam (pH 6.7), 0.20 and coarse sandy soil (pH 6.6), 0.07(1). The corresponding Koc values were 8.4, 13.3, and 5.3, respectively(1). Koc values for mecoprop were also reported as 5 to 43(2). According to a classification scheme(3), these Koc values suggest that mecoprop is expected to have very high mobility in soil. The pKa of mecoprop is 3.78(4), indicating that this compound will exist almost 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(5). Leaching experiments were conducted in which mecoprop (2.26 kg/ha) was applied to turfgrass lysimeter (37 cm soil profile) plots (prepared with 3 common northeastern soils and irrigated with 28.5 cm of water over 71 days)(6). Leachate was collected after 30, 52 and 71 days. In all three cases the maximum concentration of mecoprop in leachate was found after 52 days which was 10, 18, and 310 ppb in Hudson silt loam (pH 6.5), Arkport fine sandy loam (pH 6.5), and sand (pH 6.7), respectively(6). The soil partition coefficient of mecoprop to 5 Dutch subsoils (6-7 m below the soil surface) was very low, 0.142 to 0.326 in three soils and zero in the other two soils(7).

SECTION 13: Disposal considerations

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.
