4.2 Most important symptoms/effects, acute and delayed

Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. 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

Skin decontamination: Skin contamination should he treated promptly by washing with soap and water. Contamination of the eyes should be treated immediately by prolonged flushing of the eyes with large amounts of clean water. If dermal or ocular irritation persists, medical attention should be, obtained without delay.

5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: SMALL FIRE: Dry chemical, CO2 or water spray. LARGE FIRE: Dry chemical, CO2, alcohol-resistant foam or water spray. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal; do not scatter the material. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)

5.2 Specific hazards arising from the chemical

Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. For electric vehicles or equipment, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. (ERG, 2016)

12.2 Persistence and degradability

AEROBIC: The half-life of 2.0 ppm of cyanazine in samples of Regina Heavy Clay soil (70% clay, 25% silt and 5% sand) was determined under various laboratory soil moisture and temperature conditions(1). The half-life at 34% soil moisture content varied from 19 to 3 days at temperatures of 5 and 30 degrees C, respectively; at 8% moisture content and 20 degrees C, the half-life was greater than 200 days (1). In field experiments, the half-life of cyanazine, initially applied at approximately 5.5 lbs/acre, was approximately 30 days; after 56 days, less than 10% of the cyanazine remained(1). In the lab and field experiments, the degradation of cyanazine occurred more rapidly than metribuzin and atrazine(1). The degradation of cyanazine was measured under field conditions over a four year period and under different tillage treatments(2). Approximately 8 percent of cyanazine, initially applied at 5.5-8.8 lbs/acre, remained 2 and 4 weeks after application under no-till and conventional tilling conditions, respectively(2). Approximately 19 and 24 percent of cyanazine, initially present at 250 umol/kg, remained after 42 days in a silt loam soil that was amended with ryegrass and cornmeal, respectively; 36 percent of the applied cyanazine remained in unamended soil and soil amended with poultry litter(3). Three metabolites of cyanazine were observed (in decreasing order): hydroxy cyanazine, cyanazine amide and deethyl cyanazine(3). In a cyanazine metabolite study, cyanazine amide and de-isopropylated atrazine were detected as soil degradation products(4); it was proposed that hydrolysis preceded microbial degradation to yield the de-isopropylated atrazine(4). Persistence studies over a 20-week period at varying temperatures (5, 20, 35 and 50°C) found that cyanazine degraded within 10 weeks at 5°C and within 5 weeks at the higher temperatures(5); the initial observed half-lives at the higher temperatures were 1.5-2.0 weeks(5); it has been suggested that degradation of cyanazine at -10°C is not very likely(6). A half-life of 6 days was observed in a cornfield study in Quebec, Canada(7).

12.3 Bioaccumulative potential

Using a system developed by R. Metcalf, (14)C-ring-labeled cyanazine was introduced into an aquatic model ecosystem. After 35 days, analyses of the components were conducted. In addition to unchanged cyanazine, N-deethylcyanazine, cyanazine amide, N-deethylcyanazine amide, and three unknowns were found in the water. Radioactivity did not increase in the food chain of algae to mosquitoes to fish (a decrease from 1.3 to 0.05 ppm was observed), indicating that this compound does not concentrate through the food chain.

12.4 Mobility in soil

An experimentally determined Koc of 200 has been reported (soil type not given)(1). A Koc of 182 was measured in a silty soil(2). Using soil TLC, an intermediate mobility was measured in a silty clay loam (Rf of 0.39) and a high mobility was measured in a sandy loam (Rf of 0.74)(3); the avg Koc for these two soils was reported as 372(4). A Koc of 97 was measured for a silt loam soil from a corn field(5); in field studies using this soil (0.70% organic carbon), a max of 0.04% of surface application was lost through subsurface tile drains(5). In field studies, cyanazine did not leach below a 0.20 m depth in a sandy loam soil(6) or below a 0.30 m depth in a silt loam soil(7). However, cyanazine leached through 0.90 m of a soil composed of 29% clay, 49% silt and 22% sand(8). Cyanazine is reversibly adsorbed to soil particles(9); adsorption increases with increased organic matter content, decreasing soil water and decreasing pH(9). The adsorption of cyanazine by microbial biomass has been observed(10). According to a classification scheme(11), the measured Koc values suggest that cyanazine is expected to have moderate to high mobility in soil(SRC).

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.

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.
