Wetlands
A measure of fine sedement deposition in the intersitial spaces between rocks
Embeddedness
Peatland receiving water exlusively from precipitation and not influenced by groundwater - sphagnum dominated vegitation
Bogs
Is generally measured in volts or millivolts
Redox potential
-carcenogen
-highly toxic to the immune system
PCBs - poly chlorinated biphenols
Essential for plant growth - Not typically limiting but can be in marine/highly enriched environments - causes baby blue syndrome
Nitrogen
The interface between land and flowing surface water
Riparian zone
As the redox potential approaches zero, _________ is favoured over sulfate and sulfur
Hydrogen sulfide
-Carcenogen - byproduct of oil and gas production -mutenogenic and teratogenic
PAHs - polycyclic aromatic hydrocarbons
Phosphorus
Marshes
Continuously moving water cuts channels and also influences the types of organisms that live there
If oxygen is reintroduced, these reaction are ________
reversed
A measure of buffering/neutralizing capacity
Alkalinity
The total concentration of multivalent cations
Hardness
Periodic standing surface water and gently moving nutrient rich groundwater - dominated by woody plants more than 1 m high
Swamps
Overall productivity is influenced by the nature of the ________
When redox potential at the sedement-water interface reaches 200mV conditions are ________
Anoxic
Does not precipitate with increased temps
______ is reduced / revoved by boiling
Temporaory hardness
Peatland the receives water rich in dissolved minerals - predominatly grasses and sedges and brown mosses
Fens
Where velocity decreases downstream _________ are created
Iron will be present as Fe3+ rather than Fe2+
High redox potential
Lime addition helps to remove phosphorus by _______
raising pH
DIN and DON stand for what?
Dissolved inorganic / orgnanic Nitrogen
