Most important symptoms/effects, acute and delayed
SYMPTOMS: Symptoms of exposure to this material include increased perspiration, nausea, lachrymation, salivation, blurred vision, diarrhea, pulmonary edema, respiratory embarrassment and convulsions. ACUTE/CHRONIC HAZARDS: This material may be absorbed through the skin and is a lachrymator. It is a cholinesterase inhibitor. This compound is a positive animal carcinogen. (NTP, 1992)
Indication of immediate medical attention and special treatment needed, if necessary
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. Organophosphates and related compounds

Persistence and degradability
AEROBIC: In the environment, the main route of loss of tetrachlorvinphos is via biodegradation, with a soil half-life of 4.4 days using a Blackord loam soil and <8 days using a medium loam soil(1). Degradation of tetrachlorvinphos in soil is believed to be microbially mediated based on the observation that the rate of loss is greater than would be expected on the basis of in-vitro hydrolysis studies(2). The degradation pathway involves the cleavage of the P-O-C(alkyl) bond(2).
Bioaccumulative potential
An estimated BCF of 17 was calculated in fish for tetrachlorvinphos(SRC), using a log Kow of 3.53(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).
Mobility in soil
The Koc of tetrachlorvinphos is estimated as 2,000(SRC), using a log Kow of 3.53(1) and a regression-derived equation(2). A calculated Koc of 1,170 based on a water solubility of 11 ppm has also been reported(3). According to a classification scheme(3), these estimated Koc values suggest that tetrachlorvinphos is expected to have low mobility in soil.
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.
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.
