4.2 Most important symptoms/effects, acute and delayed
Intensely irritating to skin, eyes, and mucous membranes. Highly toxic; may cause death or permanent injury after very short exposure to small quantities. Has been listed as a direct-acting or primary carcinogen. Large doses cause central nervous system depression. (EPA, 1998)
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. /Aromatic hydrocarbons and related compounds/
5.Fire-fighting measures

- Toxicity to fish: LC50; Species: Pimephales promelas (fathead minnow); Conditions: /static/; Concentration: 11.6 mg/L for 24 hr
- Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water flea); Concentration: 4.2 mg/L for 24 hr; Effect: immobility /Conditions of bioassay not specified; from table
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
12.2 Persistence and degradability
AEROBIC: Benzyl chloride, present at 100 mg/L, reached 70.9% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). Benzyl chloride biodegraded readily with the formation of dechlorinated products during a 2-day incubation period using raw sewage and raw sewage acclimated to non-chlorinated compounds(2). However, since benzyl chloride is subject to hydrolysis(3-5), it is probably the biodegradation of benzyl alcohol that is measured in these studies(SRC).
12.3 Bioaccumulative potential
An estimated BCF of 20 was calculated in fish for benzyl chloride(SRC), using a log Kow of 2.30(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).
12.4 Mobility in soil
The Koc of benzyl chloride is estimated as 100(SRC), using a log Kow of 2.30(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that benzyl chloride is expected to have high mobility in soil.
12.5 Other adverse effects
