to drinking water backs up the authors claim that dredging stirs up mercury that has settled in California’s waterways as a consequence of historic mining. Mercury is a naturally occurring metal from Cinnabar. Mercury has a density of 13.5 where Gold has a density of 19‚ this density or weight is used to keep heavy metals in a sluice box. The US Geological Survey Study performed in 2010 could not find any trace emissions of mercury from a running dredge‚ using test equipment measuring in parts per

Alternatively Hg pool can be used where the polarisable electrode consist of dropping mercury electrode (DME) During electrolysis potential difference is applied to the cell and it is kept on increasing and corresponding current is measured. Then graph of current Vs voltage is plotted. The change in current with applied voltage gives concentration

They made an exclusive agreement with The Athletic Congress in 1992‚ so that every medallist in the Barcelona games would wear Nike Apparel.

SMALL-SCALE MINING (Lives at risk in the Philippine Gold Mines) INTRODUCTION Gold is the number one mineral produced by the Philippines in value terms. Although total local production was low relative to world production‚ it ranked 2nd to Africa in gold production per unit land area in 1988 and ranked 29th as top gold producer in 2002(Israel and Asirot 2002). In the year 2002–2007‚ the Philippines’ gold production increased by 8.2%. This contributed an average of 2% gross domestic product (GDP)

A vertical U tube of uniform cross section contains mercury in both of its arms. A glycerine (d = 1.3 g/cm3) column of length 10cm is introduced into one of the arms. Oil of density 0.8g/cm3 is poured in the other arm until the upper surfaces of the oil and glycerine are in the same horizontal level. Find the length of oil column. Density of mercury is 13.6 g/cm3.
