Interpretive Summary:

Technical Abstract: Understanding why variation exists in xenobiotic degradation rates is critical to the management of these systems. Much research has been conducted to establish how environmental factors in complex systems interact and influence these rates. Variables, including temperature, moisture, redox potential and pH will differentially affect dissipation processes such as volatilization, leaching, sorption/desorption, chemical hydrolysis and biodegradation. Important interactions include: competing moisture levels for physiological needs of micro-organisms and transport of substrates to micro-organisms with oxygen availability, leaching and volatilization; and pH of systems influencing sorption of compounds and hence bioavailability and potential to leach. This paper will extensively review these processes using xenobiotic degradation studies illustrated in the literature.
