Other information about Biodegradation by mutant microorganisms (Verschueren 1983) degradation -500 mg/I at 20 °C disruption:
mutant 100% in 4 hours
Impact on biodegradation processes; BOD test is not influenced up to 1 g/I (Verschueren 1983).
At100mg/I no inhibition of NH3 oxidation by Nitrosomonas sp (Verschueren 1983).

Other information about Rat inhalation; slight transitory effect: 129 ppm mammais Rat inhalation: fatal: 636 ppm, 4 hours
Rabbit inhalation: slight transitory effect: 97 ppm Rabbit inhalation: fatal: 258 ppm
Cat inhalation: sometimes fatal: 152 ppm
6uinea pig inhalation: slight transitory effect: 267 ppm Dog inhalation: vety slight effects: 29 ppm
Dog inhalation: 3/4; 110 ppm
Rats: ingestion: 35 ppm (4 mg/kg body weight Iday): mild signs ot toxicity (decreased water and tood consumption, decreased body weight).
100 ppm (10 mg/kg body weight/day) during 12
months: stomach papillomas (1 of 20 rats); central netvous system tumors (6 of 20 rats).
Zymbal gland carcinoma (2 of 20 rats).
Rats: inhalation: 80 ppm (6 hr/day, 5 days/week, 1 year): 3 ot 26 rats; central nervous system tumors.
(Verschueren 1983).
Effects on microorganisms Pseudomonas putida: inhibition of ceII multiplication starts at 53 mg/I (Verschueren 1983).
LC5O values to crustaceans, 6 96 hr, Crangon crangon (Adema 1976)
mgII 7.6 48 hr, Daphnia magna (LeBlanc 1980)
