Abstract
Aim: A study was
conducted with an aim to further understand the air environmental quality of
Jiaozuo City, China and characteristics of pollutants by comparing the
concentration of mercury in inhalable particles and dust of four functional
areas.
Methodology:
The
sampling filter for inhalable particles was dried at 500?C for 2
hrs before use. The dust samples were dried and grinded, and to all the
samples nitric acid and hydrofluoric acid was added for nitrification. The
concentration of mercury was determined by Atomic Fluorescence Spectrometer
after microwave digestion.
Results: The average concentration of mercury in inhalable
particulate matter was 4.44 ng m-3. was higher than the global
background values. The concentration of mercury in the dust ranged from 0.45
to 1.51 ?g g-1 and the average value was 0.86 ?g g-1,
which was 13.23 times higher than soil natural background value of mercury
(0.065 ?g g-1) in China. The analysis results of corresponding
relationship indicated that mercury in inhalable particulate matter and dust
originate from different sources. ?
Interpretation:
The
commercial and traffic activities may have a certain influence on the content
of mercury in airborne particulates in Jiaozuo City.
