Reaction mass of sodium prop-2-enesulphonate and sodium chloride

Acute Toxicity: inhalation

Administrative data

Endpoint:

acute toxicity: inhalation

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: In principle according to OECD 403, however analytical determination of the atmosphere concentration was not performed; the exposure time was 8h; method and results are poorly described in the report (however raw data are available)

- Mean weight at study initiation: 238 g (male), 181,3 g (female)

Administration / exposure

Route of administration:

inhalation: vapour

Type of inhalation exposure:

whole body

Vehicle:

air

Details on inhalation exposure:

GENERATION OF TEST ATMOSPHERE / CHAMBER DESCRIPTION
- Exposure chamber volume: 200 L air/h

TEST ATMOSPHERE
- Brief description of analytical method used: Inhalation of a vapour-saturated atmosphere at 20°C. For saturation air was disposed through a 5 cm thick product layer. The calculated vapour saturation for the a. i. is 0.00002 µg/L.

VEHICLE
- Composition of vehicle (if applicable): air

Analytical verification of test atmosphere concentrations:

no

Duration of exposure:

8 h

Concentrations:

Concentration was stated to be 4.71 mg/L calculated reweighing of the product column after exposure. Due to the very low vapour pressure ( 3e-09 hPa at 25°C) / vapour saturation (0.00002 µg/L) of the a. i. it is assumed that this substance loss is mainly based on loss of water.

No. of animals per sex per dose:

6

Control animals:

yes

Details on study design:

- Duration of observation period following administration: 7 days
- Frequency of observations and weighing: Weighing was done on day 0 and day 7. No informations about observation times.
- Necropsy of survivors performed: yes
