Hi everyone,
I need some help with the grammar and overall structure of my science paper. Please feel free to point-out any errors and suggest some corrections in my sentences.
"Limestone dust was added to Lohi Lake in 1975. This is because the lake has shown a large increase in pH (from 4.45 in 1973 to 6.12 in 1975) in just two years. During this period, the lime-base most likely reacted with the acid in Lohi Lake, raising the pH of the water. In addition, despite the high levels of sulfur dioxide, Lohi Lake was still closer to neutralization (pH=7) then Clearwater (pH 4.30) and/or Hannah (pH 5.33) Lake in 1975. Nonetheless, Lohi lake becomes, with little reduction in SO2 emissions, re-acidified within two years of liming it".
"The application of limestone, a natural source of basicity, to a watershed around Hannah Lake increased the water pH and renewed the acidified lake. The crushed limestone’s slow depletion into Hannah Lake, brought a rapid decrease in the lake’s acidity and, neutralized its waters (pH=7) by 1989. Further decreases in SO2 emissions, in addition to the lasting effects of crushed limestone, increased the pH as well as the alkalinity (pH > 7) of Hannah Lake, overtime".
"The pH of Clearwater Lake gradually increased, over the course of 18 years, solely due to the mass reduction in SO2 emissions. This change was gradual because nothing was added to relieve the acidity of the lake any sooner".
@Noor123,
"Limestone dust was added to Lohi Lake in 1975 because it had shown a large increase in pH (from 4.45 in 1973 to 6.12 in 1975) in just the last two years, the lime-base most likely having reacted with any acid. However, despite high levels of sulfur dioxide in a couple of adjoining bodies,, Lohi was still closer to neutralization (pH=7) than Clearwater (pH=4.30) or Hannah (pH 5.33) . Nonetheless....
Forgive me Noor for stopping there but didn't understand some of the rest of it and besides yardwork calls. Hope of some help
@dalehileman,
Thank you so much for your help!!
@Noor123,
Why, 123, notatall. Sonlet me try another para
But remember Noor, on my part sheer guesswork
The application of limestone, a natural source of basicity, to a watershed around Hannah Lake also increased its pH, thereby at first renewing it too. But then the limestone’s continued slow depletion surprisingly brought a rapid decrease in its acidity and, neutralizing its waters (pH=7) by 1989. Further decreases in SO2 emissions...
Sorry couldn't finish this para Noor, I'm too dumb; and read my changes carefully since, as I said, it's muchly guesswork
@dalehileman,
If however 123 my last para was okay let me know and I'll try the third. Sorry for those last two unfinished
@Noor123,
"The pH of Clearwater Lake now has gradually increased, over the course of 18 years, solely due to the mass reduction in SO2 emission; gradual to be sure, because nothing was added to relieve the acidity of the lake any sooner".
I might have also omitted "any sooner," but there are always afterthoughts of little more value. Glad to imagine I've been of some help
