This investigation analyzes the particulate-bound mercury (PBM) compositions in soil and vegetation at a traffic sampling site in Taichung, Taiwan, during a sampling period from October to December, 2015. A direct mercury analyzer (DMA-80) was used to measure the particulate-bound mercury (PBM). A T-test was conducted to determine the mean differences between the PBM composition in soil and that in vegetation at the site. The results indicate that 1) the mean particulate-bound mercury compositions in soil and vegetation were the lowest in November, when the (mean OR average) wind speed was the highest (4.1 m/s); 2) Particulate-bound mercury compositions (PBM) in both soil and vegetation correlated weakly with temperature, humidity and wind speed; 3) T-test statistical results denoted that the PBM compositions did not significantly differ between soil and vegetation in the three-month sampling period.

This study analyzes the particulate-bound mercury (PBM) contents of two parts (leaf and stem) of different crops (white cabbage, Peking cabbage, and chili) at a sampling site in the coastal zone in the Taichung area from October 7 to 15, 2014. A direct mercury analyzer (DMA-80) was used to measure mercury content. The Mann-Whitney rank sum test was utilized to determine the mean differences between the PBM in two parts of various crops (white cabbage leaf, white cabbage stem, Peking cabbage leaf, Peking cabbage stem, and chili) at the Long-Jing sampling site. The results indicated the following: 1) The average mercury content was lowest in the Peking cabbage stem. The ratio of the mercury content in the stem to that in the leaf of the white cabbage was 5 and that of Peking cabbage was 3.5.2) No significant difference was observed between median mercury content in white cabbage leaf and Peking cabbage leaf, white cabbage stem and Peking cabbage stem, and Peking cabbage leaf and chili. 3) The average PBM contents were both the lowest (Huabei Plain) and the highest in Hg in China. 4) The ratio of average PBM content of white cabbage leaf in this study was as high as 981.

PM_2.5particulates and particulate-bound mercury Hg(p) concentrations in a mixed urban, residential, traffic-heavy, and industrial site

Environmental Forensics (2017)

Guor‐Cheng Fang Chaur‐Tsuen Lo Chao-Yang Huang Yuan-Jie Zhuang Meng-Hsien Cho

This study analyzes the concentrations of ambient fine particulates and particulate-bound mercury Hg(p) at sampling sites in various areas in central Taiwan during a sampling period from January to April 2015. A Wilbur PM2.5 sampler was used to collect PM2.5 from ambient air and a DMA-80 direct mercury analyzer was used to analyze the concentration of mercury Hg(p) that was attached to PM2.5. The results show that the mean PM2.5 and Hg(p) concentrations were highest in March. The Chinese Lantern Festival and the “Faithful Pilgrims Who Follow Matsu through Taiwan” are hosted in this month. Many fireworks and firecrackers are let off at this time, releasing particulate matter into the atmosphere, increasing the concentrations of atmospheric particulate pollutants. The highest average PM2.5 concentrations were measured in January. A dust storm in Mainland China may have been responsible for this result. February saw the lowest mean PM2.5 recorded in this study, possibly because commercial districts and factories were closed in February for Chinese Lunar New Year. April saw the highest mean wind speed, diluting particulate pollutants in ambient air.
