DISTRIBUTION OF ARSENIC THROUGH WATER, SEDIMENTS AND BENTHONIC ORGANISMS OF BOHAI BAY |
|
Abstract: |
The arsenic contents in sea water, sediments, and benthods in Bohai Bay at 14 stations were determined in May 1979. The range of concentrations of arsenic in water varied from 0.56 to 2.1μg/1, with an average of 1.4μg/1; arsenic contents of sediments ranged from 9.9 -16.4 mg/kg, with an average of 12.8 mg/kg. The highest value is at the southern stations. This may be due to the arsenic enriched sediments of the Huanghe River. The levels of arsenic in benthonic organisms varied from 0.78-6.17 mg/kg, the highest being in a species of crustacean. Arsenic contents in Area subcrenata round the sites near the coast showed lower values than those far from the coast. The levels of arsenic in three mediums of Bohai Bay approach to baseline levels. |
