If inhaled

Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.

Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.

Following eye contact

Rinse with pure water for at least 15 minutes. Consult a doctor.

Following ingestion

Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.

4.2 Most important symptoms/effects, acute and delayed

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution. (ERG, 2016)

Do not scatter spilled material with high-pressure water streams. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal. FIRE INVOLVING TANKS: Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)

5.2 Specific hazards arising from the chemical

SECTION 12: Ecological information

12.1 Toxicity

Toxicity to fish: LC50; Species: Lepomis macrochirus (Bluegill, juvenile); Conditions: freshwater; flow through; Concentration: 200 ug/L for 96 hr (95% confidence interval: 130-310 ug/L) /95% purity
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: Oxyfluorfen biodegradation rate constant in non-sterile sediment was much greater (p=0.01) than sterile sediment rate constant(1). Biodegradation half-lives were given for oxyfluorfen in non-sterile estuarine sediment as 17 days and non-sterile estuarine water as 27.5 days(2). In a field study, oxyfluorfen had a half-life of 12 days in soil (20.7% sand, 32.8% silt, 46.5% clay, 7.1 pH, 5.84 g/kg organic content) with an application rate of 0.12 kg ai/ha(3).

12.3 Bioaccumulative potential

An estimated BCF of 880 was calculated in fish for oxyfluorfen(SRC), using a log Kow of 4.73(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high, provided the compound is not metabolized by the organism(SRC).

12.4 Mobility in soil

The Koc of oxyfluorfen is estimated as 8900(SRC), using a log Kow of 4.73(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that oxyfluorfen is expected to be immobile in soil(SRC). Oxyfluorfen is strongly absorbed to organic soils and only minimally leached(10). Oxyfluorfen had reported Kd values of 52-755 and 111-829 at 25 and 37 deg C, respectively in 6 different soils with moisture contents of 30-90%(4). Oxyfluorfen stayed in the top 0-10 cm of soil 28 days after application(5). Oxyfluorfen remained in the top 0-5 cm in a 1992 and 1993 study with an application rate of 1.2 kg ai/ha(6). Oxyfluorfen penetrated to 5.41-8.89 cm with 3.2-12.8 cm of rain and had a half-life in the soil of 35 days(7). Soil half-lives of 30-103 days were calculated for oxyfluorfen at different application rates and rainfall amounts(8). Oxyfluorfen has been noted as persistent and immobile in soil(9).

12.5 Other adverse effects

no data available

SECTION 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.
