SAMPLE<br />
Product remaining after incinerati<strong>on</strong> in laboratory combusti<strong>on</strong>.<br />
Organic chemicals that have a high vapour pressure and<br />
easily form vapours at normal temperature and pressure.<br />
Short chain fatty acids c<strong>on</strong>taining two to five carb<strong>on</strong> atoms<br />
that are produced as end products <str<strong>on</strong>g>of</str<strong>on</strong>g> microbial<br />
FERMENTATION in the digestive tract.<br />
Resistance <str<strong>on</strong>g>of</str<strong>on</strong>g> a fluid to a change in shape, or movement <str<strong>on</strong>g>of</str<strong>on</strong>g><br />
neighbouring porti<strong>on</strong>s relative to <strong>on</strong>e another. Viscosity<br />
denotes oppositi<strong>on</strong> to flow. The reciprocal <str<strong>on</strong>g>of</str<strong>on</strong>g> the viscosity is<br />
called the FLUIDITY.<br />
Measure <str<strong>on</strong>g>of</str<strong>on</strong>g> the ease <str<strong>on</strong>g>of</str<strong>on</strong>g> flow <str<strong>on</strong>g>of</str<strong>on</strong>g> a fluid e.g. SLURRY using<br />
special apparatus.<br />
Mass per unit volume for soil or MANURE or other<br />
substances.<br />
Together with the COD, BOD is the measure <str<strong>on</strong>g>of</str<strong>on</strong>g> the polluti<strong>on</strong><br />
potential in water bodies and organic wastes. A laboratory test<br />
is used to measure the amount <str<strong>on</strong>g>of</str<strong>on</strong>g> dissolved oxygen c<strong>on</strong>sumed<br />
by chemical and biological acti<strong>on</strong> when a sample is incubated<br />
at 20 C o for a given number <str<strong>on</strong>g>of</str<strong>on</strong>g> days.<br />
BIOLOGICAL OXYGEN DEMAND<br />
A measure <str<strong>on</strong>g>of</str<strong>on</strong>g> the amount <str<strong>on</strong>g>of</str<strong>on</strong>g> oxygen c<strong>on</strong>sumed in the<br />
microbial oxidati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> decomposable and inert organic matter<br />
and the oxidati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> reduced substances in water. The COD is<br />
always higher than the BOD, but measurements can be made<br />
in a few hours while BOD measurements take five days.<br />
This normally refers to methods for analysing <strong>manure</strong>s, most<br />
comm<strong>on</strong>ly for nitrogen c<strong>on</strong>tent, <strong>on</strong> farms without the need for<br />
a laboratory or laboratory apparatus.<br />
RAPID ANALYSIS TECHNIQUE<br />
A sample (e.g. <str<strong>on</strong>g>of</str<strong>on</strong>g> LIQUID or SOLID MANURE) that is selected<br />
in such a way that its characteristics and properties are<br />
representative, or typical, <str<strong>on</strong>g>of</str<strong>on</strong>g> the bulk <str<strong>on</strong>g>of</str<strong>on</strong>g> material from which it<br />
was taken. .
