Consult a physician. Show this safety data sheet to the doctor in attendance.

If inhaled

Fresh air, rest. Refer for medical attention.

In case of skin contact

Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .

In case of eye contact

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

If swallowed

Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention .

4.2 Most important symptoms/effects, acute and delayed

This material is a cholinesterase inhibitor. It can cause severe symptoms and death from respiratory arrest. (EPA, 1998)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

Airway protection. Insure that a clear airway exists. Intubate the patients and aspirate the secretions with a large-bore suction device if necessary.

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LD50 Salmo gairdneri (Rainbow trout) 0.020 mg/l/96 hr @ 13°C (95% confidence limit 0.016-0.025mg/l), wt 1.7 g. Static bioassay without aeration, pH 7.2-7.5, water hardness 40-50 mg/l as calcium carbonate and alkalinity of 30-35 mg/l.
  • 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

Biodegradation is the major process for the loss of dyphonate in soil(1). Biodegradation of dyphonate is faster in dyphonate-treated soil than untreated soil(2,3). The major metabolite of biodegradation of dyphonate in dyphonate-treated soil is carbon dioxide with dyphonate-oxon, methyl phenyl sulfone and other unidentified polar products as minor metabolites(4).

12.3 Bioaccumulative potential

A BCF of less than 2 for dyphonate was measured using mosquito fish (Gambusia affinis)(1). A BCF of 300 has also been reported but with a 90% depuration within 14 days(2). According to a classification scheme(3), BCF values of <30 are low and from 100 to 1000 are high(SRC). Aquatic organisms readily metabolize this class of compounds(4) and organophosphates can be altered chemically(5) once released into the environment.

12.4 Mobility in soil

Koc values for dyphonate in soil vary widely and range from 68 to 5,128(1-6). According to a classification scheme(7), Koc values of 50 to 150 indicate high mobility and greater than 5,000 indicate immobile in soil. Laboratory and field leaching studies indicate that dyphonate has low to very low mobility in silt loam, sandy loam and organic soil, but is relatively mobile in quartz sand(8-10). The adsorption of dyphonate increases with decreasing temperature and increase in organic content, particularly humic acid and associated cation content of soil(11). A certain fraction of both dyphonate and its oxon metabolite form bound residues in soil and the latter fraction increases with time(12).

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.
