Following eye contact

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

Following ingestion

Rinse mouth. Give a slurry of activated charcoal in water to drink. Rest. Refer for medical attention .

Most important symptoms and effects, both acute and delayed

Exposure Routes: inhalation, ingestion, skin and/or eye contact Symptoms: Irritation eyes, skin, respiratory system; numb mucous membrane; nausea, vomiting, abdominal pain; muscle tremor, incoordination, clonic convulsions, stupor Target Organs: Eyes, skin, respiratory system, central nervous system (NIOSH, 2016)

Indication of any immediate medical attention and special treatment needed

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Rotenone and related compounds

Sweep spilled substance into covered air-tight containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

Environmental precautions

Sweep spilled substance into covered air-tight containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Personal protection: P3 filter respirator for toxic particles. Do NOT let this chemical enter the environment.

Methods and materials for containment and cleaning up

1. Ventilate area of spill. 2. For small quantities, sweep onto paper or other suitable material, place in an appropriate container and burn in a safe place (such as a fume hood). Large quantities can be reclaimed; however, if this is not practical, dissolve in a flammable solvent (such as alc) and atomize in a suitable combustion chamber.

SECTION 10: Stability and reactivity


Decomposes on burning. This produces irritating fumes.

Chemical stability

Decomp upon exposure to light and air. Colorless solutions in organic solvents oxidize upon exposure and become yellow, orange and then deep red and may deposit crystals of dehydrorotenone and rotenonone which are toxic to insects.

Possibility of hazardous reactions

Flammable if preheated.ROTENONE is readily oxidized in the presence of alkalis. It is incompatible with oxidizers. (NTP, 1992).

Conditions to avoid

no data available

Incompatible materials

Strong oxidizers, alkalis.

Hazardous decomposition products

When heated to decomposition it emits acrid smoke and irritating fumes.

SECTION 12: Ecological information


  • Toxicity to fish: LC50; Species: Lepomis macrochirus (Bluegill) weight 1-1.5 g; Conditions: freshwater, static, 12 deg C, pH 8.0, hardness 300 mg/L CaCO3, alkalinity 225-245 mg/L CaCO3, dissolved oxygen >60%; Concentration: 138 ug/L for 24 hr (95% confidence interval: 125-152 ug/L) /5% purity emulsifiable concentrate

  • Toxicity to algae: EC50; Species: Scenedesmus subspicatus (Green Algae); Conditions: freshwater, static; Concentration: 240000 ug/L for 49-79 min; Effect: decreased population photosynthesis /100% purity
  • Toxicity to microorganisms: no data available

Persistence and degradability

AEROBIC: In southern Italy, two types of soil samples spiked with rotenone, a silt clay loam and a loamy soil, underwent degradation experiments in dark conditions at 10-20 deg C. The results indicated that half-life values for rotenone were 8 days in the silt clay loam soil and 5 days in the loamy soil at 20 deg C. At 10 deg C however, the half-lives were 25 days for silt clay loam soil and 21 for the loamy soil(1). Rotenone is listed as one of the organic substances which may be degraded during aerobic and anaerobic sewage treatment if adequate acclimatization can be achieved; much depends on the concentration to be treated and possibly on the temperature during treatment(2).

Bioaccumulative potential

A study showed that when yearling bluegills (Lepomis macrochirus) were exposed to 5.2 ug/L of rotenone for 30 days in a continuous flow system, bioconcentration factors for the head, viscera, and carcass were 165, 3,500, and 125, respectively(4). According to a classification scheme(3), bioconcentation factors of 100-100 are high and >1000 are very high(SRC).

Mobility in soil

The Koc of rotenone is estimated as approximately 3,200(SRC), using a measured log Kow of 4.10(1) and a regression-derived equation(2). According to a recommended classification scheme(3), this estimated Koc value suggests that rotenone is expected to have slight mobility in soil(SRC). The Kd values of rotenone were determined in 2 different soil types from Southern Italy. In the adsorption experiment Kd values were 0.56 and 2.73 L/kg for silt clay loam and loamy soil respectively, and the degradation rates were 0.102 and 0.074 d-1 for soils at 20 deg C(4).

Other adverse effects

no data available

SECTION 13: Disposal considerations

Disposal methods


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.
