4.2 Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 151 [Substances - Toxic (Non-combustible)]: Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2016)
4.3 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. /Carbamates and related compounds/

10.3 Possibility of hazardous reactions
... FLAMMABILITY POINT OF 193 DEG C.CARBARYL is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates. This compound is unstable in an alkaline media. . This compound is incompatible with the following: Strong oxidizers, strongly alkaline pesticides (NIOSH, 2016).

Reproductive toxicity
No information is available on the reproductive or developmental effects of carbaryl in humans. Two studies produced teratogenic effects in dogs fed carbaryl, but dogs were judged inappropriate for human health risk assessment because of differences in metabolism. Other studies demonstrating teratogenic effects also caused maternal toxicity. Reduced fertility and litter size and increased mortality in offspring have been observed in rats exposed to carbaryl in their diet over three generations.

12.2 Persistence and degradability
THE PERSISTENCE OF 14C-CARBONYL-LABELED CARBARYL AT CONCN OF 2 & 200 PPM IN 5 DIFFERENT JAPANESE RICE PADDY SOILS WAS STUDIED. EVOLUTION OF CARBON DIOXIDE WAS NOT RAPID & VARIED BETWEEN 2% & 40% OVER 32 DAY TEST PERIOD. HYDROLYSIS OF CARBONYL LINKAGE WAS THE DOMINANT METABOLIC PATHWAY. AN ISOLATED SOIL MICROORGANISM RAPIDLY DEGRADED NAPHTHOL & PRODUCED A NUMBER OF UNIDENTIFIED AROMATIC COMPOUNDS.
12.3 Bioaccumulative potential
Carbaryl had a measured BCF value of 34, 30 and 9 in golden orfe(1), golden ide(2), and topmouth gudeon, respectively(3). An avg BCF of 9 was determined based on data compilations of freshwater fish at steady state with carbaryl in solution and by the kinetic method (ratio between first-order uptake and elimination rate constants)(4). According to a classification scheme(5), these BCF values suggest the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
Carbaryl was estimated to leach <20 cm/yr assuming an annual rainfall of 150 cm; a loam soil and a temperature of 25°C were assumed(1). Soil-sorption coefficient (Koc) values of 370 and 390 were determined using a soil slurry method and reverse phase HPLC, respectively(2). In another study, carbaryl had a Koc value of 230(3). Freundlich k values are 0.017 and 0.046 in kaolinite and bentonite clays, respectively(4). In Ca-bentionite, alluvial and highly calcareous soils, the Freundlich adsorption isotherm showed a non-linear pattern and the adsorption was found to be temperature dependent, the adsorption being higher at lower temperature(5). In a study of the degradation and sorption from urban creek sediments from southern California, the sorption coefficient of carbaryl increased with time, indicating that in sediment carbaryl may become less available over time because of increased sorption(6). After 1 day of incubation, the estimated Koc was 310 to 420 for carbaryl. The measured Kd values of carbaryl in sediment after 1, 2, 6, and 28 days were 2.1, 2.4, 5.6, and 47.7 mL/g, respectively(6). A Koc of 230 mL/g has been reported for carbaryl(7). Carbaryl was reported to have a mean Koc value of 288 in the 1993 UK database(8). According to a classification scheme(2), these Koc values suggest that carbaryl is expected to have moderate mobility in soil.

13.Disposal considerations
13.1 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.
