12.1 Toxicity

  • Toxicity to fish: LC50 Lepomis macrochirus (bluegill) 0.50 mg/l/48 hr /Conditions of bioassay not specified
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

Aerobic degradation of 10 ug 2,4,5-T of soil was 5-35% in unsterilized tropical clay and silty clay soils and <1% in sterilized soils after 4 months incubation(1). In Vietnamese soils, 64-69% aerobic degradation of 1 ppm 2,4,5-T occurred in 49 days, 74-96% aerobic degradation of 15 ppm 2,4,5-T occurred in 168 days and no degradation was observed in sterilized soils(2). The primary degradation product of 2,4,5-T in aqueous and soil systems is 2,4,5-trichlorophenol(3). Aerobic metabolism of 2,4,5-T leads to formation of 2,4,5-trichlorophenol and 3,5-dichlorocatechol which may further degrade to 4-chlorocatechol or cis,cis-2,4-dichloromuconic acid, 2-chloro-4-carboxy-methylene-but-2-enolide, chlorosuccinic acid and succinic acid(2). Degradation under anaerobic conditions has led to the formation of di- and mono-chlorophenols and 2,5-dichlorophenoxyacetic acid(4,5). Anaerobic degradation occurs much more slowly than aerobic degradation(6).

12.3 Bioaccumulative potential

The bioconcentration factor (BCF) of 2,4,5-T in static ecosystem tests has been measured to be 23-25 in fish(1,2). Under flowing water conditions its estimated BCF in fish is 43(1). Based on these BCF values, bioconcentration in aquatic organisms should not be significant.

12.4 Mobility in soil

Measured soil adsorption coefficient (Koc) values for 2,4,5-T in various soils are as follows: 86-sand, 186-whole soil, 204-fines, 205-coarse clay, 206-coarse silt and 280-medium silt(1). Measured soil TLC Rf values are as follows: 0.17-muck, 0.48-clay, 0.54-silt clay loam and 0.73-0.89-sandy loam(2). These Koc and Rf values indicate that 2,4,5-T mobility in soil should vary from highly mobile in sandy soil to moderately mobile in clay and silt loams to slightly mobile in muck (3,4). Humic acids found in almost all water and soil systems have been shown to strongly adsorb 2,4,5-T from solution(5), and the tendency of 2,4,5-T to adsorb to soil has been observed to increase with increasing organic content in soil(6). When 11.2 kg/ha 2,4,5-T was applied to a large field lysimeter, 96-99% of the undegraded herbicide remained 0-10 cm deep and 0.33-3.7% remained between 10 to 30 cm deep after 2-3 winters(7). Up to 8 weeks following application of 1 g/cu m 2,4,5-T, 86-98% of the undegraded 2,4,5-T applied to arable land remained within the top 30 cm of the soil layer and 84-100% remained within the top 10 cm of forest soil(8).

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.
