摘要: The biodegradabilities of five unformulated mineral oils (brightstock, 150 SN base oil, white oil and two gas oils) were determined in the CEC L-33-A-93 test during 20 weeks incubation nutrient-supplemented soil microcosms. Biodegradation both studies was measured as loss extractable hydrocarbon (‘primary’ biodegradation). There a statistically significant (P <0.01) rectilinear relationship between extents biodegradation systems. results indicate that method could be used relatively simple, quick inexpensive for assessing potential based lubricants soil.
