TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 210(SRC), determined from a measured water solubility(2) and a recommended regression-derived equation(3), indicates that Menazon will have moderate mobility in soil(SRC). Based on limited data, Menazon is expected to biodegrade in soil(SRC). A half-life of 23 days was measured for Menazon (at 10 ppm) in a sandy loam soil; Menazon at 250 ppm disappeared at a similar rate(4). Volatilization of Menazon should not be important from moist soil surfaces(SRC) given an estimated Henry's Law constant of 1.5X10-9 atm-cu m/mole(SRC), calculated from experimental values for vapor pressure(5) and water solubility(2). Volatilization from dry soil surfaces(SRC) is not expected based on a measured vapor pressure of 9.75X10-7 mm Hg(4). This compound is expected to photodegrade on soil surfaces; in sunlight, Menazon photooxidizes with the conversion of the P:S group to P:O with a decomposition half-life of 10.5 hours(6).

AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 210(SRC), determined from a measured water solubility(2) and a recommended regression-derived equation(1), indicates that Menazon may adsorb to suspended solids and sediment in water(SRC). Based on limited data from soil studies, Menazon may biodegrade in water(SRC). A half-life of 23 days was measured for Menazon (at 10 ppm) in a sandy loam soil; Menazon at 250 ppm disappeared at a similar rate(3). Menazon should not volatilize from water surfaces based on an estimated Henry's Law constant of 1.5X10-9 atm-cu m/mole(SRC), calculated from experimental values for vapor pressure(4) and water solubility(2). An estimated BCF value of 30(1,SRC), from a measured water solubility(2), suggests that Menazon may moderately bioconcentrate in aquatic organisms(SRC), according to a recommended classification scheme(5).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), Menazon, which has an estimated vapor pressure of 9.75X10-7 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase Menazon is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be about 5 hours(3,SRC). Particulate-phase Menazon may be physically removed from the air by wet and dry deposition(SRC).

Workers handling & applying pesticides must undergo an annual medical examination at the beginning of each agricultural season. Contraindications for work with /organophosphorus pesticides/ are organic diseases of the central nervous system, mental disorders & epilepsy, pronounced endocrine & vegetative disorders, pulmonary tuberculosis, bronchial asthma, chronic respiratory diseases, cardiovascular diseases & circulatory disorders, gastrointestinal diseases (peptic ulcer), gastroenterocolitis, diseases of liver & kidneys, eye diseases (chronic conjunctivitis & keratitis). The blood cholinesterase activity must be determined before work starts. In the event of prolonged work periods, this activity should be determined at intervals of 3-4 days. Persons exhibiting a fall in cholinesterase activity of 25% or more must be transferred to other work where they are not exposed to organophosphorus pesticides until this activity is completely restored. Persons with initial signs of indisposition should cease work with pesticides. /Organophosphorus pesticides/

A final diagnosis of mild to moderate acute organophosphate pesticide poisoning is rarely justified unless all of the following five conditions are present: 1. A definite history of exposure to an organophosphate pesticide. 2. A latent interval of not more than a few hours between that last exposure and the onset of illness. 3. A clinical picture in which most or all of the following signs or symptoms are present: headache, blurred vision, weakness, tightness in chest, and constricted pupils. 4. Reduction of plasma and RBC cholinesterase activity to a level substantially below 50% of baseline values. Because of the wide normal range of RBC cholinesterase in the population, symptoms may be present with reported "normal" levels. 5. An acute illness that is not substantially longer than 48 hours. The classic presentation for acute organophosphate toxicity includes history, evidence of exposure to organophosphate (garlic odor), signs/symptoms of cholinergic excess, improvement with atropine or pralidoxime, and inhibition of cholinesterase in blood. /Organophosphate pesticide poisoning/

... Surveillance of workers could be carried out through measurement of blood or urinary levels of the cmpd to which they are exposed, or through measurement of a metabolite. /Organic phosphorus pesticides/

The Koc of Menazon is estimated as approximately 210(SRC), using a measured water solubility of 240 mg/l(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that Menazon has moderate mobility in soil(SRC). Menazon penetrated in small amounts, to about 15 cm depth, when applied to the soil surface(4).

An estimated BCF value of 30 was calculated for Menazon(SRC), using a measured water solubility(1) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is moderate, not high(SRC).

The Henry's Law constant for Menazon is estimated as 1.5X10-9 atm-cu m/mole(SRC) from its experimental values for vapor pressure, 9.75X10-7 mm Hg(1), and water solubility, 240 mg/l(2). This value indicates that Menazon will be essentially nonvolatile from water surfaces(3,SRC). Menazon's values for vapor pressure(1) and Henry's Law constant(1,2,SRC) indicate that volatilization from dry and moist soil surfaces should not occur(SRC).

The signs of poisoning due to organophosphorus cmpd are those due to accumulation of acetylcholine & hence overstimulation of parasympathetic nervous system. It is usual to divide them under 3 headings: muscarinic, nicotinic & central. Muscarinic signs ... consist of hypersalivation, lacrimation, sweating & nasal discharge. Miosis, dyspnea, vomiting, diarrhea & frequency of urination ... Nicotinic effects consist of fasciculation of muscles, weakness & paralysis. Central nervous system effects include nervousness, apprehension, ataxia, convulsions & coma. Death is due to resp failure, or sometimes cardiac arrest. There is little difference between signs produced by different organophosphorus compounds, but route of absorption may influence one system more than another. /Organophosphorus cmpd/

The cardiovascular actions of anticholinesterase agents are complex, since they reflect both ganglionic and postganglionic effects of accumulated ACh on the heart and blood vessels. The predominant effect on the heart from the peripheral action of accumulated ACh is bradycardia, resulting in a fall in cardiac output. Higher doses usually cause a fall in blood pressure, often as a consequence of effects of anticholinesterase agents on the medullary vasomotor centers of the CNS. /Anticholinesterase agents/

Organophosphorus derivatives act by combining with and inactivating the enzyme acetylcholinesterase. ...

Plasma and tissue enzymes are responsible for hydrolysis /of organophosphorus compounds/ to the corresponding phosphoric and phosphonic acids. However, oxidative enzymes are also involved in the metabolism of some organophosphorus compounds. /Anticholinesterase agents/

The organophosphorus anticholinesterase agents are hydrolyzed in the body by a group of enzymes known as A-esterases or paroxonase, and by the cytochrome p-450 systems. Considerable variability exists in the human population for organophosphate metabolism by these routes. The A-esterases are found in plasma and in the hepatic endoplasmic reticulum and can hydrolyze a large number of organophosphorus compounds ... by splitting the anhydride, P-F, P-CN, or ester bond. /Anticholinesterase agents/

These chemicals are detoxified by cytochrome p450-mediated monooxygenases in the liver, but some metabolites are more toxic than parent cmpd ... Metabolites usually are detected from 12 to 48 hr postexposure. /Organophosphate cmpd/
