4.2 Most important symptoms/effects, acute and delayedSYMPTOMS: This compound is a LACHRYMATOR. Symptoms of exposure to this compound include irritation of the skin and eyes. It also causes sensitization of the skin. Irritation of the nose and mouth may occur. ACUTE/CHRONIC HAZARDS: This compound is a LACHRYMATOR. It is toxic by ingestion and inhalation. It is a severe eye irritant and mild primary skin irritant IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.
4.3 Indication of immediate medical attention and special treatment needed, if necessary/SRP:/ 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 if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the 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. /Poisons A and B/

12.Ecological information 12.1 Toxicity- Toxicity to fish: LC50; Species: Lepomis macrochirus (Bluegill, 35 mm standard length); Conditions: freshwater, static, 21°C, pH 7.1-7.4, dissolved oxygen 3.5-8.8; Concentration: >32000 ug/L for 24 or 48 hr /100% purity
- Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water flea, age <24 hr); Conditions: freshwater, flow through; Concentration: 11900 ug/L for 48 hr (95% confidence interval: 9500-14800 ug/L); Effect: intoxication, immobilization /99% purity

- Toxicity to microorganisms: no data available
AEROBIC: Dazomet, present at 100 mg/L, reached 4% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). The rate of disappearance of dazomet from both an unamended and sterilized Williamson silt loam was identical, indicating that the initial phase of degradation in soil occurred predominantly from nonenzymatic mechanisms(2). The rate of degradation of dazomet in soil, as measured by the release of methyl isothiocyanate, was found to be independent of the soil microorganisms present(3).
12.3 Bioaccumulative potentialAn estimated BCF of 2.4 was calculated for dazomet(SRC), using a log Kow of 0.63(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). In addition, dazomet is rapidly hydrolyzed in both fresh and salt water(4) and is not expected to be present for sufficient periods of time for bioconcentration(SRC).
12.4 Mobility in soilThe Koc of dazomet is estimated as 52(SRC), using a log Kow of 0.63(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that dazomet is expected to have high mobility in soil; however it is expected to hydrolyze(1) before extensive leaching occurs(SRC).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe 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 packagingContainers 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.
