In epidemiological study, respiratory effects caused by irritation and effects on the central nervous system were reported (ECETOC TR1 (1979)). In animal experimnet, squamous metaplasia in the nasal tissues, squamous metaplasia in the larynx, inflammation in the tracheal lumen, body weight loss, metaplasia of the bronchial epithelium, dyspnea, restlessness, hunched posture and death were reported (CERI Hazard Data Book (1997)). Based on these effects, the respiratory organs and centralnervous system are considered to be the target organs. And these effects were observed within the guidance values for Category 1 in the repeated-dose study. Therefore, the substance was classified as Category 1 (respratory organs, central nervous system).
10 Aspiration hazard Classification not possible - - - - Due to the fact that formaldehyde is a gas at ordinary temperatures and no data are available on the inhalation toxicity of formalin (formaldehyde solution) to the respiratory organs.

ENVIRONMENTAL HAZARDS

11 Hazardous to the aquatic environment (Acute) Category 2 - - H401: Toxic to aquatic life P273: Avoid release to the environment.
P501: Dispose of contents/container to ...
It was classified into Category 2 from 96 hours LC50=1.8mg/L of the fish (Morone Saxatilis) (CICAD40 (2002) and others.).
11 Hazardous to the aquatic environment (Long-term) Not classified - - - - Since there was rapidly degrading (the decomposition by BOD: 91% (Existing Chemical Safety Inspections Data)) and the bio-accumulation was low (log Kow=0.35 (PHYSPROP Database, 2005)), it was claasified into Not classified.
