For a binary mixture in which the presence of the one substrate does not affect the biodegradation rate of other, the no-interaction sum kinetics model can be described as:
Based on previous tests, biodegradation will take on average several months in a backyard composter.
That, Kujawinski says, suggests no biodegradation of DOSS--and shows why remnants of dispersant applications could be detected up to 300 kilometers from the wellhead and two months after the last application.
According to the team, the concentrations of DOSS indicate that little or no biodegradation of the dispersant substance had occurred.
Contamination and biodegradation in extreme environments has received little attention although many contaminated ecosystems present high or low temperatures, extreme acidic or alkaline pH, high pressures or high salinity (1).
In May 2010, ART reported the results of an in vivo study of 48 porcine arteries implanted with its biodegradable stent, which demonstrated that the ART stent's biodegradation is measurable and begins at the first day of implant; the ART stent retains high radial strength, thus maintaining its structural integrity during biodegradation; and that the ART stent causes virtually no inflammation of the blood vessel wall.
Environmental Protection Agency defines biodegradation as "a process by which microbial organisms transform or alter (through metabolic or enzymatic action) the structure of chemicals introduced into the environment.
This work describes two methods of chemical modification of cellulose fibers aimed at protecting textile materials against biodegradation from microbial attack.

RIFM's environmental sciences program encompasses aquatic and terrestrial testing, biodegradation and bioaccumulation studies, and risk assessments of priority fragrance materials, which have been used for agency evaluations and industry REACH compliance.
