Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
In a study from Brooke et al. (1984) a 96h LC50 of 61 mg/l has been determined for the effects of furan on mortality of the freshwater fish Pimephales promelas, based on measured concentrations. Another short-term study reports a 48 h EC50 value of 71 mg/l on behaviour and equilibrium effects of furan on P. promelas (Call. et al. 1981, as cited in US EPA database). The Japanese Ministry of Environment (MoE, 2010a) reports a 96 h LC50 value of >120 mg/L with Oryzias latipes.
A long-term toxicity fish study with P. promelas derived a 31-33 day NOEC value of 8.3 mg/l (measured concentration) based on one or more parameters of hatchability, larval development, survival or growth (Call et al. 1985). A study from Call and Geiger (1992, as cited in US EPA database) reports a 33 d NOEC value of 36 mg/l based on mortalities of P. promelas.
A short-term toxcity to invertebrates and algal inhibition study have been conducted by the Japanese MoE (2010b, c) determining EC50 values of >58 mg/l and 110 mg/l respectively, with Daphnia magna and Pseudokirchneriella subcapitata respectively. The studies have been conducted according to OECD guidelines 202 and 201 and in compliance with GLP.
No data are available concerning the long-term toxicity of furan to invertebrates, or toxicity to sediment organisms.
