You better be sitting down while reading this.
I highlighted the "best" parts.
The parts I "like" the best:
a. 1 person in opposition
b. Definition of a suction dredge "contains ANY OF THE FOLLOWING...."
That description pretty much rules out everything except a gold pan and a spoon.
How good propagandist science is made to obtain a desired shocking sentence.
-A four inch dredge releases 10 percent of the annual discharge of a watershed (how big is watershed)in a DRY year..Answer;in a dry year there is just not enough waterforce to move the heavy mercury,so there is basically no mercury release in a dry year ,meaning if in the dry year 1gram of mercury is released by the watershed himself,if you move 100miligrams with your four inch you got your 10 percent.And this ten percent where ALREADY in the river.Then they don,t mention that the four inch dredge in the same time Recovered a 1000 percent of the natural release of a watershed in DRY year.
Countermath;(i don,t fill in the correct numbers,i don,t know them,just to show the relations) a four inch dredge releases 0.00000001percent released from a watershed (they don,t mention the size of the watershed) in a NORMAL year, or 0.0000000000000001percent in a flood year.Also then do not mention that the 4 percent of the mercury that escaped (while recovering 96 percent)from the dredge recovery system quickly settles back beeing heavy and because dredging does not happening during floods so it wan,t stay suspended .And then do not mention that in the next flood there will be less mercury released in that watershed because the dredge removed it.
Thats why they work with percentages,(because weights probably would be ridiculous) and a dry year to construct a shocking sentence.Picking selective equations.Not a overall picture.Not mentioning the benefits etc..
Somebody knows who dredged,with what equipment?
Correct me if i,m wrong,I,m no expert in this
p.s.Above all, They state; "a suction dredge COULD release 10 percent of the .."
Yeah..Probably at full throttle washing out everything out of the box..
