Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution. (ERG, 2016)
Indication of immediate medical attention and special treatment needed, if necessary
Skin decontamination. Skin contamination should be 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. Other herbicides
SECTION 5: Firefighting measures
Suitable extinguishing media
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: SMALL FIRE: Dry chemical, CO2, water spray or regular foam. LARGE FIRE: Water spray, fog or regular foam. Do not scatter spilled material with high-pressure water streams. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal. FIRE INVOLVING TANKS: 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)

Persistence and degradability
AEROBIC: Microorganisms are believed to play a role in the degradation and disappearance of oryzalin from soil. No specific soil organism has been identified as responsible for the degradation(1). In 6-month incubation studies using a non-sterile and sterile (via propylene oxide treatment) sandy loam soil, oryzalin degraded much faster in non-sterile soil indicating that soil microorganisms actively participate in the degradation(2). In soil, radiolabeled-oryzalin exhibited an ave overall half-life of 2.1 months at 24 deg C(3). The major degradate was 4-hydroxy-3,5-dinitro-benzenesulfonamide, which accounted for a maximum of 4.7% of the radioactivity(3). Eight other degradates were isolated, each accounting for < 2.4% of the applied radioactivity(3). The benzenesulfonamide ring remained intact in all of the identified metabolites(3). By the end of the experiment at 6 months, 63% of the applied radioactivity was nonextractable and 6% had been mineralized to carbon dioxide(3).
Bioaccumulative potential
A BCF range of 32-328 has been reported for oryzalin(1,2). According to a classification scheme(3), these BCFs suggests the potential for bioconcentration in aquatic organisms is moderate-to-high(SRC). Using 14C-labeled oryzalin and a terrestrial aquatic laboratory model ecosystem, oryzalin BCF values of 50 and 328 were determined for fish (Gambusia affinis) and snails, respectively(1). Oryzalin was not highly concentrated in bluegill sunfish: having a BCF of 32 in edible tissue, 106 in nonedible tissue, 66 in whole fish(2). Within 24 hrs depuration period for bluegill sunfish, there was 79%, 81% and 81% loss of radioactivity in edible, nonedible and whole fish respectively(2). By day 14, there was a loss of 89%, 95% and 94% in edible, nonedible and whole fish respectively(3).
Mobility in soil
The avg Koc value is 600, with ranges from 93 to 2700(1). According to a classification scheme(2), the avg Koc value suggests that oryzalin is expected to have low mobility in soil. Results of field, greenhouse and laboratory studies have shown that oryzalin does not leach appreciably in soil(3,4). In several tests, surface applied oryzalin typically remained in the upper 7.5 cm soil profile with only minor amounts reaching the 15 cm depth(3,4). Soil movement appears to decrease with decreases in the moisture content(3).
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.
