Abstract
Selected crop plants are carrot, Indian mustard, bracken, spinach, dropwort, roots of
Chinese bellflower and mushrooms. The origins of selected crop plants are Gwangju
(Korea), Jeju Island (Korea), North Korea and China. Crop plant samples were
collected from local markets. Fresh (#1‐12) vegetables were freezed with liquid
nitrogen and pulverized, while dry samples (#13‐19) were ground directly. Samples
were treated with both US EPA 1632 method and Me‐OH(1:1) extraction. An aliquot
of 6mL of the extract of each sample was filtered through a Supelclean TM LC‐SAX
cartridge followed by analysis by HG‐AAS (Hydride Generation Atomic Absorption
Spectrometer) for As concentrations.
Fern brake (#8 from North Korea, boiled) contains a distinctively high As
concentration. The concentration is more than 30ppm in fern brake sold in a local
market, while the local product (#7 from Gwangju) contains below 5 ppm. Indian
mustard (#3 from Gwangju) contains the second high As levels in leaves but arsenic
concentration in another Indian mustard (#4 from Gwangju) is significantly lower. It
showed high variation of As content in Indian mustard depending on the origin
places. By comparing Chinese bellflower samples #9 and #10, it demonstrates that
As concentration in Chinese bellflower from Gwangju (#9) is much lower than that
from China (#10). For carrots, the concentrations of two samples purchased from
different markets are similar. This result does not support the assumption of high
arsenic concentrations in carrots growing in Jeju Island, whose surface soil is
composed of scoria.
For commercially dried mushroom and fern brakes, they
contain much lower arsenic wherever the origin of the product is.

Abstract
During the years between 284 to 364 AC, an ancient Chinese metallurgist named Ge
Hong, reported in a book: Weipozi: Godʹs Medicine that elemental arsenic (As) could
be made from some natural arsenic compounds such as realgar (AsS) and orpiment
(As2S3) using oxidation‐reduction method. Ancient Chinese people knew to use
arsenic compounds as pesticides about 4000 years ago. Realgar (AsS) and orpiment
(As2S3) were used in traditional Chinese medicines at least 2000 years ago. Due to the
extensive use of As‐containing compounds, arsenic mining activities and geogenic
sources, environmental contamination with arsenic is extensive in China. In China,
there are several geological areas where high As concentrations were found, such as
in Xinjing province, Inner Mongolia, Shanxi province, Hunan Province, Yunnan
province, Guizhou and Guangxi provinces. High concentrations of As in
groundwater and in coal are responsible for arsenism in most of the places stated
above. Mining activities has also been causing As contamination, particularly in
arable soils. For example, paddy soils of over 500 hectares had been polluted by
arsenic (As) from tailings at an abandoned lead‐zinc‐silver mine in Shaoxing,
Zhejiang province, China. The highest As concentration in the paddy soil is up to
1708 mg/kg. This present will illustrate the problems of As contamination in China,
and discuss the current efforts in remediating As‐contaminated environments.

Abstract
From late 1990s, As has drawn a considerable amount of attention from many
international researchers. The interest was likely triggered by discovery of serious As
contamination of groundwater in some southern Asian countries such as Bangladesh,
where 30 million people drink ground waters containing elevated concentrations.
Historically As is notorious for its toxicity and one of its compounds, As2O3, has been
widely used as a homicidal agent. In addition to its acute toxicity, chronic effects of
As include cancer (skin, bladder and liver cancers). According to IRIS (Integrated
Risk Information Systems) of US EPA, As is the sole inorganic element which
definitely causes the cancers after long‐term inhalation and intake among many
inorganic elements. As well, As is mutagenic and can cause other diseases such as
melanosis and gangrene.
Since As is naturally incorporated into a variety of metal‐bearing ores, especially
sulfides, long‐term mining and smelting of As‐bearing minerals have resulted in
contamination of nearby air, soil, sediment and aquatic system with As. Refinement
of especially gold ore, where arsenopyrite (FeAsS) often coexists as a gangue mineral,
can act as a serious source of As contamination. In addition, anthropogenic local,
point sources of As occur in a broad range: coal combustion, hide tanning waste,
pigment production for paints and dyes, byproduct of sulfuric acid manufacturing,
processing of pressure‐treated wood, cotton desiccants, arsenic‐based pesticides,
herbicides, and fungicides, production and storage of chemical weapons, and poultry
industry.
In addition to the anthropogenic point sources of As, natural broad sources of As
also increase the risk of exposure to As. For example, according to recent lowering of
As criteria in drinking water to 10 ppb by US EPA, a huge population acquiring its
drinking water from private bedrock aquifer wells in eastern New England is subject
to drink water with arsenic greater than 10 ppb. The naturally As‐polluted wells are
spatially localized in a specific geology which is metamorphosed marine sediments
containing various sulfide minerals. The natural sources of As include marine shale
materials, magmatic sulfides, and iron ores where it occurs as arsenopyrite (FeAsS),
realgar (AsS), and orpiment (As2S3). According to Oremland and Stolz (2003),
“ironically, it is these natural sources that are of the most concern to human health
on a global basis”, which is evidenced by the Bangladesh case.

Studies on geochemical behavior of As during the past decade revealed that
microorganisms play a significant role in electrochemical speciation and cycling of
As in nature. Some bacteria can alter electrochemical species of As in association
with their metabolism under aerobic and/or anaerobic conditions. Such influence of
bacteria on changes in redox state of As plays an important role in the
biogeochemical cycling of this toxic element in nature.
A variety of bacteria are reported to change the valence of As(V) to As(III) in an
attempt to reduce As toxicity in the cells. Occasionally, bacteria take large quantity of
As(V) during the process of phosphate uptake since the chemical properties of
arsenate and phosphate are similar. In order to remove As(V) toxicity, the bacteria
reduce As(V) to As(III) and expel As(III) out of the cells. Such microbial reductive
detoxification of As which occurs under both aerobic and anaerobic conditions is not
coupled to the cell growth.
In comparison, some anaerobes can gain energy to support growth and maintenance
by coupling As(V) reduction to oxidation of organic matter. These dissimilatory Asreducing
bacteria use As(V) as a terminal electron acceptor during respiration. To
date, a total of 17 As(V)‐respiring prokaryotes have been described. The organic
matters, serving as electron donors, include hydrogen, acetate, formate, pyruvate,
butyrate, citrate, succinate, fumarate, malate, glucose and more complex aromatic
molecules such as benzoate and toluene. The dissimilatory As(V)‐reducing bacteria
are also reported to be able to use the other electron acceptors such as sulfate,
selenate, nitrate, nitrite, fumarate, Fe(III), thiosulfate, elemental sulfur,
dimethylsulfoxide, and trimethylamine oxide.
In addition to the direct reduction of As(V) described above, bacteria can
increase As mobility in nature through reductive dissolution of Fe. Iron is one
of the most abundant and reactive elements in soil formation and Fe oxides or
hydroxides readily incorporate other trace metals and metalloids through
adsorption and coprecipitation. Under anaerobic environment, dissimilatory
Fe‐reducing bacteria dissolve Fe minerals (whether they are crystalline or
amorphous) by altering Fe(III) to aqueous Fe(II) and, subsequently, As
associated with the Fe minerals is leached out into solution. Some bacteria can
also increase As mobility under aerobic condition by dissolving Fe sulfide
minerals which contain As in their crystal structure. Acidithiobacillus
ferrooxidans, a S‐ and Fe‐oxidizing bacterium, oxidizes arsenopyrite, orpiment,
and enargite (Cu5AsS4), and leach As in their crystal lattice into aqueous
phase.
Indigenous bacterial mediation of As in contaminated sediment and tailings in an
abandoned Au‐Ag mine area in Korea was investigated after biostimulation with a
variety of carbon sources such as acetate, lactate, and glucose under aerobic and
anaerobic conditions.
According to the results of both aerobic and anaerobic incubation of the
contaminated sediment, As stabilization in the subsurface was ultimately expected.
Under aerobic condition, indigenous bacteria extracted As from sediment into
solution and oxidized dissolved As(III) to As(V). Arsenate can be re‐sorbed to the
surface of Fe‐oxides/hydroxides in the sediment. As well, it can migrate downward
6

to reducing subsurface and will be transformed to As(III), and thus mobility will
increase. However, in such case, based on the results of this study, biotic reduction of
the other main compounds such as Fe(III) and SO4 2‐ could affect As behavior. For
example, As(III) can be combined with hydrogen sulfide which is a product of
bacterial sulfate reduction and can form solid arsenic trisulfide. Arsenic will then be
precipitated and finally stabilized in the geological media with mobility decreased.
According to the experimental results of As adsorption onto Pseudomonas aeruginosa,
Gram‐negative bacterium easily found in various natural settings, both forms of As
did not adsorb onto cell surfaces of bacteria themselves, possibly due to electrostatic
repulsion between As and functional groups distributed on the cell surface. The
results implied that bacteria cannot mediate the fate of As in geological media by
only adsorption process.

About GIST
The GIST was established by the Korean government as a new educational and research
institute in an effort to excel in research and development of technologies and in producing
high qualified scientists and engineers. The preparatory committee for founding the Institute
was formed in October 1991 based on the feasibility study conducted during 1989 to 1991.
On August 5, 1993, the legislature approved the law for establishing the Gwangju Institute of
Science and Technology, and the enforcement ordinance was made on September 6, 1993.
On October 11 of the same year, the construction of the campus begun at the Institute site
located at the Gwangju Science and Technology Park, and Dr. Doo Bong Ha was inaugurated
as the first president of the Institute. The first meeting of the board of trustees was held on
December 16, 1993.
On March 9, 1995, the Institute had the opening ceremony with 113 graduate students
admitted from various colleges and universities around the nation. Top Students throughout
the country were encouraged to apply for admission, and the competition ratio was over ten
to one. The Institute currently has over 63 faculty members, and it offers M.S. and Ph.D.
degrees for the following programs: Information & Communications, Materials Science &
Engineering, Mechatronics, Environmental Science & Engineering, and Life Science.
Location
The Gwangju Institute of Science and Technology (GIST) is located in the Gwangju Science
and Technology Park in a northern suburb of Gwangju. The city of Gwangju is located 200
miles south of Seoul and 150 miles west of Pusan.
Gwangju is well known for its cultural activities. In 1995, the city began hosting the Gwangju
Biennale, a binnial international art Olympiad, on a regular basis. Gwangju is also famous for
its excellent cuisine. Every year the city hosts food festivals featuring a wide variety of foods.
In the downtown area of Gwangju, one can find many restaurants, movie theaters and shops,
including big department stores.
Weather
It is summer in Korea and the weather varies from cool to hot. Temperature ranges from 25°
C in the daytime to 15° C at night. The organizers suggest you bring summer clothes with a
light jacket.
Accommodation (for international participants)
We will arrange one guest room (on campus, apartment style) for each international
participant. Each apartment unit has two guest rooms, so one participant will have his own
room and share one apartment unit with the other one. The apartment has a kitchen, shower
room and washing machine. It takes about 7 minutes by walk from the apartment to the
venue. The on‐campus cafeteria offers breakfast from 8:00‐9:00am (1500won). Organizers
will arrange lunch and dinner for you. A medium size shopping mall (9am‐11:30pm) locates
where 15 min by walk from the campus.
