Toxicity to terrestrial plants
Administrative data
Link to relevant study record(s)
- Endpoint:
- toxicity to terrestrial plants: short-term
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 12 OCT - 16 DEC 1993
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: GLP - guideline study with acceptable restrictions
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 208 (Terrestrial Plants Test: Seedling Emergence and Seedling Growth Test)
- Deviations:
- yes
- Principles of method if other than guideline:
- The test method was modelled after OECD guideline 208 but adapted to the gaseous nature of the test substance. Thus, the substance was not mixed with soil but the plants were exposed to the gas in closed chambers. In contrast to the guideline only the effect was only tested with two plant species. Two assays were conducted. In a first assay both plant species were exposed. In the second assay only Lepidum sativum was exposed to the substance.
- GLP compliance:
- yes
- Analytical monitoring:
- yes

- - Concentrations: 10 ppmv and 100 ppmv nominal
- Sampling method: samples for gas chromatographic analysis of ethylchlorid within the gas phase were taken from the influent and effluent - Vehicle:

Description of key information
Key value for chemical safety assessment
Additional information
Chloroethane is a gaseous substance and thus will mainly distribute to the air if released to the environment. There is no intended release of the substance to soil during its lifecycle. An exposure of the terrestrial compartment is therefore not anticipated.
Due to its gaseous nature chloroethane is characterised by a high vapour pressureof 134200 Pa at 20 °C (62330 Pa at 0 °C) and subsequently by a high evaporation rate from water to air as indicated by aHenry's Law constant of 1124.70 Pa m³/mol calculated for the substance. If the substance is released to the waste water it will rapidly evaporate from the water phase in conventional sewage treatment plants during the primary treatment. The substance will not adsorp to suspended matter or activated sludge as indicated by the low log Pow (1.34) and the correlated log Koc value (<3) . An exposure of soil via sewage sludge application can be excluded.
One study investigating the effect of chloroethane to terrestrial plants is available. The test investigated the effect of the substance on emergence and growth of the plant species Avena sativa and Lepidum sativum. The plants were exposed to the gas at concentrations of 10 and 100 ppmv in a closed chamber. The test was terminated after 14 days. Avena sativa was not affected by the substance. Whereas the growth of Lepidum sativum was reduced by 20% compared to control. Thus, the EC50(14d) for both plant species is > 100 ppmv.
