Environmental Transfomation/Degredation Flashcards
Hydrolysis
The addition of an OH group onto a chemical, usualy leads to less toxic substances.

Phototransformation
reactions caused by absorbtion of light, a minimum amount of energy is required.

Phototransformations
Rate of phototransformation
Affected by flux, absorbance range of the molecule, and energy of the photon

Lag phase
the time between when a chemical is introduced to an environment and when the microbial population starts to increase to eat it.
the time between when a chemical is introduced to an environment and when the microbial population starts to increase to eat it.
lag phase
effects on lag phase
Prior exposure, # of initial microbes, other energy sources, and amount of chemical.

anoxic metabolization
Starts breaking down nitrates (NO3^-), then sulfates (SO4^2-), and finaly interacting the carbohydrates with themselves (methanogenesis)

Degredation by higher organisms
P450 Isozymes add OH groups to make it more soluble in water, may be followed by other reactions to break it down further.
