01 March 2013
2012 PBC-SEGH Joint Symposium on Environmental and Public Health perspectives: a brief description of abstracts is given.

The 2012 PBC (Pacific Basin Consortium for Environment and Health)-SEGH Joint Symposium was successfully held at the Gwangju Institute of Science and Technology (GIST) in Korea on 10-12 April 2012. This jointly ventured symposium was hosted by Professor Kyoung-Woong Kim (Member of SEGH Executive Board) and brought a new audience to the SEGH. It gave our members an opportunity to exchange ideas on new interesting perspectives, such as environmental and public health sciences. The selected articles were published in a special issue of ‘Reviews on Environmental Health’ from the symposiumA Brief description is given for each abstract, follow the link to read more. http://www.degruyter.com/view/j/reveh.2012.27.issue-4/issue-files/reveh.2012.27.issue-4.xml

Special vulnerability of children to environmental exposures

Sly, J. Leith / Carpenter, David O.

The environment in which fetal and childhood development occurs is very important. Unfortunately, poverty is a major risk factor for both exposures and childhood and later-life disease resulting from exposures to both environmental chemicals and infectious agents.

Improving access to adequate water and basic sanitation services in Indonesia

Haryanto, Budi / Sutomo, Sumengen

The development of water and basic sanitation services in Indonesia does not indicate any significant progress in the last two decades. The prevalence of water-borne diseases tends to increase yearly, which poses a risk for a population of over a million people. Therefore, it is not realistic to achieve the Millennium Development Goals target by 2015. Redefining approaches like providing integrated programs and action in water and sanitation services must be a priority to protect human health in Indonesia.

A framework for assessing and predicting the environmental health impact of infectious diseases: a case study of leptospirosis

Lau, Colleen / Jagals, Paul

The application of an integrated environmental health impact assessment (IEHIA) methodology to assess the health impact of an infectious disease was shown to enhance the ability to quantify associations between a disease agent and its health impact by taking into account the environmental drivers of transmission, human behaviour, socioeconomic factors, and the multiple pathways through which exposure and infection could occur.

Nanoparticles in the environment: stability and toxicity

Kim, Hyun-A / Choi, Yoo Jin / Kim, Kyoung-Woong / Lee, Byung-Tae / Ranville, James F.

This review presents a brief overview of the fate, behavior, and ecotoxicity of nanoparticles (NPs) in the environment. The fate and transport of NPs, which can be affected by various environmental conditions like light, pH, ionic strength, and type and concentration of cations, are important for the examination of the life cycle of NPs.

Nature’s cure for cleanup of contaminated environment – a review of bioremediation strategies

Prasad, Majeti Narasimha Vara / Prasad, Rajendra

Bioremediation technologies resting upon the vast potential of biodiversity for the monitoring and abatement of environmental pollution have been briefly reviewed.

Arsenic and human health: epidemiologic progress and public health implications

Argos, Maria / Ahsan, Habibul / Graziano, Joseph H.

Herein, we emphasize the role of recent genetic and molecular epidemiologic investigations of arsenic toxicity. Additionally, we discuss considerations for the public health impacts of arsenic exposure through drinking water with respect to primary and secondary prevention efforts.

Direct potable reuse of reclaimed wastewater: it is time for a rational discussion

Arnold, Robert G. / Sáez, Avelino E. / Snyder, Shane / Maeng, Sung Kyu / Lee, Changha / Woods, Gwendolyn J. / Li, Xiangdong / Choi, Heechul

Engineered solutions to relieve water stress are frequently based on the use of water of impaired initial quality. Chief among these impaired waters is reclaimed wastewater. For the most part, however, the breadth of both acceptable uses and use-dependent degree of treatment for reclaimed wastewater remain to be established.

Persistent toxic substances: sources, fates and effects

Wong, Ming H. / Armour, Margaret-Ann / Naidu, Ravi / Man, Ming

This article is an attempt to review the current status of Persistently Toxic Substances (PTS) in our environment, citing case studies in China and North America, and whether our existing drinking water treatment and wastewater treatment processes are adequate in removing them from water. Some management issues of these emerging chemicals of concern are also discussed.

  • Assessment of arsenic (As) occurrence in arable soil and its related health risk in China 2016-06-01

    Abstract

    Arsenic (As) is a major global environmental pollutant due to its high toxicity on human and animal health. This study collected 427 relevant papers to study As concentrations in Chinese arable soil and evaluate the health risk of exposure to As for humans. Results showed that the average of As concentration was 9.46 mg/kg in Chinese arable soil. Soil As concentrations in Hunan Province and Guangxi Zhuang Autonomous Region posed high carcinogenic and non-cancer risks on human health through diet, Yunnan, Guizhou, Guangdong, and Xinjiang provinces had relative high health risks, while As concentrations in the other provinces posed low health risks on humans. The physical factors controlled the spatial pattern of health risk on a provincial scale, but the As-related human activities introduced high health risk on people, particularly the agricultural activities such as sewage irrigation and fertilizer application should be given more attention due to its large area.

  • Mercury distribution in organs of fish species and the associated risk in traditional subsistence villagers of the Pantanal wetland 2016-06-01

    Abstract

    This study evaluated the risk to human health from mercury (Hg) exposure through fish consumption in the Pantanal, Brazil. In order to address these risks, Hg concentrations and accumulation patterns were determined in target organs of predatory fish (Crenicichla lepidota and Pygocentrus nattereri). Levels of Hg were analysed during the two phases of the flood pulse (flood and drought) in fish from different local ecosystems, such as the Bento Gomes and Paraguay rivers. Although the former study area is directly affected by gold mining, a higher, but not significantly different, Hg concentration in fish was found compared with fish at the Paraguay River, which is regarded as pristine area. Moreover, no seasonal variability was found in either river. Although total mercury levels in fish did not exceed the maximum FAO/WHO threshold (0.5 μg g−1), according to dietary habits in riverine communities of the Pantanal (up to 6 oz of fish per day), there is reason for concern over the potential for deleterious health effects that could be caused by high Hg intake. In fact, the estimated daily intake in the present study ranged from 0.49 to 1.08 μg Hg kg−1 day−1, for adults (including women of childbearing age) and children, respectively. Because of high Hg intakes in riverine groups, which exceed the recommended reference dose value, these communities could be considered at risk. Therefore, it is necessary to consider regulatory measures and public education regarding fish consumption, particularly in vulnerable groups (i.e. children, pregnant women and women of childbearing age).

  • Current status of arsenic exposure and social implication in the Mekong River basin of Cambodia 2016-06-01

    Abstract

    To evaluate the current status of arsenic exposure in the Mekong River basin of Cambodia, field interview along with urine sample collection was conducted in the arsenic-affected area of Kandal Province, Cambodia. Urine samples were analyzed for total arsenic concentrations by inductively coupled plasma mass spectrometry. As a result, arsenicosis patients (n = 127) had As in urine (UAs) ranging from 3.76 to 373 µg L−1 (mean = 78.7 ± 69.8 µg L−1; median = 60.2 µg L−1). Asymptomatic villagers (n = 108) had UAs ranging from 5.93 to 312 µg L−1 (mean = 73.0 ± 52.2 µg L−1; median = 60.5 µg L−1). About 24.7 % of all participants had UAs greater than 100 µg L−1 which indicated a recent arsenic exposure. A survey found that females and adults were more likely to be diagnosed with skin sign of arsenicosis than males and children, respectively. Education level, age, gender, groundwater drinking period, residence time in the village and amount of water drunk per day may influence the incidence of skin signs of arsenicosis. This study suggests that residents in Kandal study area are currently at risk of arsenic although some mitigation has been implemented. More commitment should be made to address this public health concern in rural Cambodia.
