Description of key information

A study was available which provides data of the half life of fuel oils with similar carbon ranges to the members of this Category. The half lives of the fuel oils considered ranged from 4.4 weeks to >48 weeks depending on soil type, incubation temperature or the amount of fuel added to the soil. 

Key value for chemical safety assessment

Additional information

A study was available for CAS No 68476 -33 -5. (Song 1990) This study had limitations in design and reporting but is considered adequate for assessment. Half lives of fuel oils (jet fuel, heating oil, diesel oil with a carbon range of C9 -C23) were determined in different soil types, at different incubation temperatures and at varying amounts of fuel added to the soils. The half lives of the fuel oils considered ranged from 4.4 weeks to >48 weeks depending on soil type, inclubation temperature or the amount of fuel added to the soil.
