Emesis should not be induced when petroleum distillate additives are present unless the product ingested is estimated to contain a near lethal dose (1 g/kg) of pyrethrum or pyrethrins... Pulmonary & allergic sequelae are treated symptomatically with airway maintenance, oxygen, & ventilatory assistance as required.

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50; Species: Oncorhynchus mykiss (Rainbow trout); Concentration: 56 ppb for 24 hr /Conditions of bioassay not specified; Pyrethrins
  • 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

Although environmental biodegradation data specific to pyrethrin I are not available, the pyrethrin class of insecticides is readily degraded by ambient microorganisms(1,2); based upon its structure, pyrethrin I is also expected to readily biodegrade(1,2).

12.3 Bioaccumulative potential

An estimated BCF of 200 was calculated in fish for pyrethrin I(SRC), using a log Kow of 5.9(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(SRC), provided the compound is not metabolized by the organism(SRC). However, bioconcentration studies on compounds which are structurally similar suggest that bioconcentration may be lower than that indicated by the regression-derived equations due to the ability of aquatic organisms to readily metabolize this class of compounds(4).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of pyrethrin I can be estimated to be 10,200(SRC). According to a classification scheme(2), this estimated Koc value suggests that pyrethrin I is expected to be immobile in soil(SRC).

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.
