  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

PURE CULTURE: A Pseudomonas strain, isolated from soil, was able to utilize 4-methylbenzaldehyde as the sole carbon source, giving 0.18, 0.27, and 0.43 um O2 consumed/min/mg dry weight cells, for cells previously grown on m-xylene, p-xylene, and p-methylbenzyl alcohol, respectively(1). The rates of formation of aromatic carbinol and aromatic alcohol from a yeast culture grown in both 4-methylbenzaldehyde and sucrose are 1.71 and 1.78 g/L, respectively for a 1 hr incubation(2). The rates of formation of aromatic carbinol and aromatic alcohol from a yeast culture grown in both 4-methylbenzaldehyde and pyruvate are 1.86 and 0.08 g/L, respectively, for a 1 hr incubation(2).

12.3 Bioaccumulative potential

An estimated BCF of 8 was calculated in fish for 4-methylbenzaldehyde(SRC), using a water solubility of 2,270 mg/L(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 4-methylbenzaldehyde is estimated as 62(SRC), using a water solubility of 2,270 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 4-methylbenzaldehyde is expected to have high mobility in soil.

Skin:
Wear appropriate gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize contact with skin.
Respirators:
Wear a NIOSH/MSHA or European Standard EN 149 approved full-facepiece airline respirator in the positive pressure mode with emergency escape provisions. Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149.
