Total mercury is typically determined using CVAAS after complete conversion of all mercury to the volatile elemental form using harsh (nitric acid/perchloric acid bromate/bromide) digestions followed by reduction of ionic mercury to the elemental form Inorganic mercury can be determined after milder digestions (HCl sulfuric acid) and reduction

Porosity φ is the fraction of the total soil volume that is taken up by the pore space Thus it is a single-value quantification of the amount of space available to fluid within a specific body of soil Being simply a fraction of total volume φ can range between 0 and 1 typically falling between 0 3 and 0 7 for soils

Acceptable limits for mercury in soil were determined at a site with mercury contamination after measuring the soil concentration of total mercury the species of mercury and the intestinal absorption of mercuric sulfide by mice The total concentration of mercury at this site ranged from 0 5 to 3 000 ppm Of the total mercury present 88% was identified as mercuric sulfide 0 01% as methyl

Sample Preparation and Analysis

Mercury in soils was determined by the method described in section 'Stream and floodplain sediments/Determination of mercury' Total multielement determination by XRF A range of elements was determined by wavelength dispersive x-ray fluorescence spectrometry (WD-XRFS) using Philips PW1480 and PW2400 WD-XRFs with Cr and Rh anode x-ray tubes

Jul 11 2017This study investigated total mercury contents in areas impacted by aluminium plants in Tajikistan and Slovakia and in one area flooded with red mud in Hungary We present the first determination of total mercury contents in the near-top soil (0–10 and 10–20 cm) in Tajikistan and the first comparative investigation of Tajikistan-Slovakia-Hungary

The toxicity of mercury depends on its chemical state [3] Some forms of mercury are relatively non-toxic and have been used as medicines e g for the treatment of syphilis [4] Speciation of mercury at trace and ultra-trace levels is a matter of current interest [4] Mercury enters the environment mainly through human activities [5]

wastewater containing high levels of mercury the levels of total mercury and alkyl mercury must be evaluated according to these official standards The background levels of total mercury are generally 0 5-3 ng/L (ppt) for ocean water 2-15 ng/L (ppt) for shore water and
