we did water quality and my job was turbidity. parameter means job. this is another Q+A session, so you can skip around. **what is your parameter?** hmm, i sorta already answered this... well, mai parameter is turbidity. that means measuring how much stuff is in the water, how clear it is. **how does it affect water quality?**
it affects it by blocking light. no light equals no plants. no plants, well, no oxygen.
DEAD DEAD DEAD DEAD DEAD.
**how is it measured?**
in NTUs. Nephelometric Turbidity Units. heres how you get the NTU count. you take a water sample in a little test tube and put it in a little machine thing and close the lid. it shoots light through the water to sensors on the other side, and if there is stuff in the water, it can sense it.
**what levels are good?**
low levels, like 0-25 NTUs
**what levels are acceptable?**
toughie......well......lets see...25-100 NTUs......the higher levels arent very acceptable though.... they are more NOT acceptable.....
**what are bad levels?**
100+ NTUs now that just makes me SAD.
**how does it affect fish?**
hhhhrrrmmmm...... well.... ok, done thinking. large amounts can clog the gills of fish and shellfish directly, so they suffocate. particles can provide a home for harmful microorganisms. fish cant see very well in turbid water, etc.
**how does it affect people?**
its bad for them, stuff can stick to the particles of dirt and you can get sick
thats all about my parameter. the end.
