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.

Most important symptoms and effects, both acute and delayed

SYMPTOMS: Symptoms of exposure to this compound may include liver and kidney damage. Based on data for a similar compound, symptoms may also include vomiting, headache, fatigue, malaise, numbness and partial paralysis of the extremities, moderate ataxia, exaggeration of part of the reflexes, mild convulsions, loss of porprioception and vibratory sensation of the extremities, hyperactive knee-jerk reflexes, excitement, confusion and increased respiration. It may also cause nausea and diarrhea. Other symptoms may include tremors of the head and neck muscles, cardiac and respiratory failure and even death. It may also cause paresthesias of the tongue, lips and face, irritability and dizziness. It may cause tonic and clonic convulsions. Other symptoms include apprehension and hyperesthesia of the mouth and face. It may also cause "yellow vision". ACUTE/CHRONIC HAZARDS: This compound is harmful if ingested, inhaled or absorbed through the skin. It may cause irritation. There is clear evidence that this compound is an animal carcinogen. When heated to decomposition it emits very toxic fumes of carbon monoxide and carbon dioxide. It may also emit toxic fumes of hydrogen chloride gas. (NTP, 1992)

Indication of any immediate medical attention and special treatment needed

Observation. Persons exposed to high levels of organochlorine pesticides by any route should be observed for sensory disturbances, incoordination, speech slurring, mental aberrations, and involuntary motor activity that would warn of imminent convulsions. Solid organochlorine insecticides

SECTION 5: Firefighting measures

SECTION 6: Accidental release measures

Personal precautions, protective equipment and emergency procedures

Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.

Environmental precautions

Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.

Methods and materials for containment and cleaning up

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a POTW is acceptable only after review by the governing authority. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must meet Hazardous Material Criteria for disposal.

SECTION 7: Handling and storage

Precautions for safe handling

Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Conditions for safe storage, including any incompatibilities

PRECAUTIONS FOR "CARCINOGENS": Storage site should be as close as practicable to lab in which carcinogens are to be used, so that only small quantities required for ... expt need to be carried. Carcinogens should be kept in only one section of cupboard, an explosion-proof refrigerator or freezer (depending on chemicophysical properties ...) that bears appropriate label. An inventory ... should be kept, showing quantity of carcinogen & date it was acquired ... Facilities for dispensing ... should be contiguous to storage area. Chemical Carcinogens

Reproductive toxicity

No information is available on the reproductive or developmental effects of DDT or DDE in humans via inhalation exposure. No studies are available on the developmental effects in humans after oral exposure to DDT or DDE. However, DDT and DDE have been found in human blood, placental tissue, and umbilical cord blood. Epidemiologic studies did not find an association between DDT maternal blood levels and miscarriages or premature rupture of fetal membranes in humans. Oral animal studies have reported reproductive effects, such as reduced fertility, adverse effects on spermatogenesis, and decreased testicular and ovarian weights from DDT exposure. Developmental effects, such as embryotoxicity and fetotoxicity, but not teratogenicity (birth defects) have also been observed in oral animal studies. DDT has been shown to elicit estrogenic activity in rats after oral exposure .

SECTION 12: Ecological information

Toxicity

  • Toxicity to fish: LC50; Species: Oncorhynchus mykiss (Rainbow trout, weight 0.8 g); Conditions: freshwater, static, 12 deg C, pH 7.1, hardness 44 mg/L CaCO3; Concentration: >87 ug/L for 24 hr /99% purity, technical material
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

Persistence and degradability

AEROBIC: DDE was not degraded in static screening tests using settled domestic wastewater inoculum with yeast extract, with 3 additional subcultures added every 7 days(1). No degradation of DDE exposed to ocean sediments in seawater under aerobic conditions were observed after 12 months(2). No degradation of DDE observed after 8 weeks of exposure of DDE in lab tests to raw water from a stream which received domestic and industrial wastes and farm runoff(3). Half-life of DDE exposed to river sediments was 1,100 days(4). BOD after 30 days of <1.0 ug O2/mL for DDE exposed to soil inoculum indicated only slight biodegradation(5).

Bioaccumulative potential

BCF values of DDE have been reported in the following aquatic organisms: rainbow trout, 81,000(2); fathead minnow, 51,000(3); fish (no species reported, static microcosm study), 27,500(4); Gambusia affinis, 217 (3 days exposure)(1); trout, 1.8X10+5, bluegill sunfish, 1.1X10+5(6). According to a classification scheme(7), these BCF data suggest bioconcentration in aquatic organisms is very high(SRC). BCF values of 28,600 have been reported in zooplankton(5).

Mobility in soil

The Koc value of p,p'-DDE in soil from Taichung, Taiwan was measured as 26,300(1) and 75,860(2) in soil column batch experiments. The avg log Koc value of DDE in lake sediment was 4.58(3). According to a classification scheme(4), these Koc values suggest that DDE is expected to be immobile in soil(SRC).

Other adverse effects

no data available

SECTION 13: Disposal considerations

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.
