12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50 Salmo gairdneri (Rainbow trout) 20 ppm/96 hr /Technical; conditions of bioassay not specified
  • Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water flea, age <24 hr); Conditions: freshwater, static, 21°C; Concentration: 78000 ug/L for 24 hr; Effect: intoxication, immobilization /96-99.9% purity
  • Toxicity to algae: EC50; Species: Pseudokirchneriella subcapitata (Green algae) Conditions: freshwater, static; Concentration: 98 ug/L for 5 days (95% confidence interval: 88-108 ug/L); Effect: population abundance /97% purity
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: In one investigation, no changes in phytotoxicity were observed in moist, organic soil treated with 17.5 ppm of prometon after 8 wk of incubation; the soil was adjusted to four pHs: 4.3, 5.3, 6.5, and 7.5(1). Several soil bacteria and fungi are reported to attack prometon(2). However, it is not known whether biodegradation is the primary degradation process in soil(2). Methoxy-s-triazines are more resistant to biodegradation than the corresponding methylthio- and chloro-s-triazines(2). Average soil half-life is reported as 932 days(3). In soil, microbial degradation involves hydrolytic cleavage of the methoxy group to give hydroxy metabolites, and dealkylation of the side chains(4). Persistence in soil can be as much as one year, depending upon soil type, moisture, and the application rate(4).

12.3 Bioaccumulative potential

An estimated BCF of 19 was calculated in fish for prometon(SRC), using a log Kow of 2.99(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

A mean Koc of 524.3 was reported for prometon in 29 soils(1). The Freundlich adsorption constant, K, and exponent, 1/n, for prometon on San Joaquin sandy loam (0.72% organic carbon, 9.7% clay, pH 6.2) at 25°C were 2.94 and 0.81, respectively; the corresponding Koc is 408 at a concn of 1 ppm and 305 at a concn of 10.3 ppm(2). Koc values of 572 and 395 were determined in Hanford sandy loam (0.43% organic C, pH 6.05, 7.1% clay, 25.8% silt, 67.1% sand) and Tujunga loamy sand (0.33% organic C, pH 6.3, 4.5% clay, 13.5% silt, 82.0% sand), respectively(3). According to a classification scheme(4), these Koc values suggest that prometon is expected to have low to moderate mobility in soil(SRC). Only 0.1% of prometon applied to a 30.5 cm column and leached under unsaturated flow conditions with 1.2 cm of water/day, was found in leachate at the end of 30 days(5). Prometon was included in mobility class 3, on a scale from 1 (immobile) to 5 (very mobile)(6). Prometon is adsorbed onto soil humic acid, forming stable complexes(7). Ionic, hydrogen bonding, electron donor-acceptor, and covalent forces contribute to the binding. The fact that the basicity of several s-triazines, and hence their tendency to form ionic bonds, is not correlated with adsorptivity indicate that ionic bonding is not the primary factor governing adsorption(7). Data on the free radical content of humic acid adducts, demonstrate that electron donor-acceptor forces are particularly important in the binding of prometon to soil(7). The Freundlich adsorption constant, K, and exponent, 1/n, for prometon on Volcay bentonite at 25°C was 150 and 0.64, respectively(8). The mean sorption coefficient (Kd) of 4.86 was given for 59 measured values(9). A pKa of 4.3 at 21°C(10) indicates prometon will exist predominately in the unionized form under environmental pHs(SRC). Max adsorption of prometon onto soil organic matter occurred in the pH range 4.2 to 5.2; the addition of HCl or NaOH decreased adsorption(11). Approximately 52% of the prometon adsorbed by organic matter was desorbed with two extractions of 0.1 N NaCl(11).

12.5 Other adverse effects

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.
