Persistence and degradability

AEROBIC: In an aerobic grab sample study, 60.5% chlorothalonil (initial concentration of 38 ppm) remained in an alluvial silty loam (25 deg C and pH 6.4) after 7 days(1). At an initial concentration of 40 ppm, 67.5% (20 deg C) and 45.0% (25 deg C) chlorothalonil remained after 7 days in an alluvial silty loam (pH 6.4) held at a 60% moisture capacity(1). In the same soil held at moisture capacities of 100, 60, 40, and 20%, the amount of chlorothalonil (initial concentration of 40 ppm) remaining was determined to be 85, 22, 45, and 65%, respectively, after 7 days. Chlorothalonil biodegraded mainly through dechlorination and partly by substitution reaction yielding the biodegradation products: isophthalonitrile, mono-, di- and tri-chlorinated isophthalonitriles, 2,5,6-trichloro-4-hydroxyisophthalonitrile and 2,5,6-trichloro-4-methoxyisophthalonitrile(1). Aerobic biodegradation half-lives of chlorothalonil in four different soils were reported as 10, 10, 15 and 40 days(2). After 60 days the metabolite 2,5,6-trichloro-4-hydroxyisophtalonitrile was present at up to 32% of the initially applied amount; the metabolite 3-cyano-2,4,5,6-tetrachlorobenzamide was present at up to about 7% at both days 7 and 16 of the study. Aerobic aquatic half-lives of chlorothalonil typically range from 2 to 200 hours(2). Other reported metabolites are 1,3-dicarbamoyl-2,4,5,6-tetrachlorobenzene, 1-carbamoyl-3-cyano-4-hydroxy-2,5,6-trichlorobenzene, 2,4,6-trichloro-4-(methylthio)isophthalonitrile and pentachloronitrobenzene(3).

Bioaccumulative potential

Bioconcentration factors of 75 (edible) and 264 (whole body) were measured for chlorothalonil in bluegill sunfish(1). BCF values of 9.4 (edible) and 16 (whole body) were reported for catfish(1). Carp exposed to 3 ug/L chlorothalonil over a 6 week incubation period had reported maximum BCF values of 125 (2). A BCF of 264 was determined in bluegill (Lepomis macrochirus) exposed for 28 days(3). According to a classification scheme(4), these BCF values suggest bioconcentration in aquatic organisms can be low to high(SRC). Chlorothalonil BAFs wet weight and lipid based in zooplankton from three lakes in southern Ontario, Canada were 14-1500 and 140-190,000, respectively; samples were collected in 2003 and 2004(5).

Mobility in soil

A Koc value of 1800 has been determined based on adsorption isotherms of chlorothalonil on 3 black soils and 1 clay mineral, Na-bentonite soil(1). Other reported Koc values are 1300 to 14,000(2). Laboratory batch equilibrium studies with four soils showed chlorothalonil to possess limited mobility in silty clay loam, silt, sandy loam, and sand with calculated Koc values were 1400, 7000, 1100, and 900, respectively(3). According to a classification scheme(4), these Koc values suggest the mobility of chlorothalonil in soils will be low to immobile(SRC). The Koc of sediment from recycling ponds was 2270 to 2450(5).

Other adverse effects

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.
