2012 PBC-SEGH Joint Symposium on Environmental and Public Health Sciences

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.

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.

  • Positive anomalous concentrations of Pb in some gabbroic rocks of Afikpo basin southeastern Nigeria 2016-08-01


    Gabbroic rocks have intruded the sedimentary sequence at Ameta in Afikpo basin southeastern Nigeria. Petrographic and geochemical features of the rocks were studied in order to evaluate their genetic and geotectonic history. The petrographic results show that the rocks contain plagioclase, olivine, pyroxene, biotite, iron oxide, and traces of quartz in three samples. Major element characteristics show that the rocks are subalkaline. In addition, the rocks have geochemical characteristics similar to basaltic andesites. The trace elements results show inconsistent concentrations of high field strength elements (Zr, Nb, Th, Ta), moderate enrichment of large-ion lithophile elements (Rb, Sr, Ba) and low concentrations of Ni and Cr. Rare earth element results show that the rocks are characterized by enrichment of light rare earth elements, middle rare earth elements enrichment, and depletion of heavy rare earth elements with slight positive europium anomalies. Zinc concentrations are within the normal range in basaltic rocks. There are extremely high concentrations of Pb in three of the rock samples. The high Pb concentrations in some of these rocks could be as a result of last episodes of magmatic crystallization. The rocks intruded the Asu River Group; organic components in the sedimentary sequence probably contain Pb which has been assimilated into the magma at the evolutionary stage of the magma. Weathering of some rocks that contain galena could lead to an increase in the concentration of lead in the gabbroic rocks, especially when the migration and crystallization of magma take place in an aqueous environment. Nevertheless, high concentration of lead is hazardous to health and environment.

  • Estimated lead (Pb) exposures for a population of urban community gardeners 2016-08-01


    Urban community gardens provide affordable, locally grown, healthy foods and many other benefits. However, urban garden soils can contain lead (Pb) that may pose risks to human health. To help evaluate these risks, we measured Pb concentrations in soil, vegetables, and chicken eggs from New York City community gardens, and we asked gardeners about vegetable consumption and time spent in the garden. We then estimated Pb intakes deterministically and probabilistically for adult gardeners, children who spend time in the garden, and adult (non-gardener) household members. Most central tendency Pb intakes were below provisional total tolerable intake (PTTI) levels. High contact intakes generally exceeded PTTIs. Probabilistic estimates showed approximately 40 % of children and 10 % of gardeners exceeding PTTIs. Children’s exposure came primarily from dust ingestion and exposure to higher Pb soil between beds. Gardeners’ Pb intakes were comparable to children’s (in µg/day) but were dominated by vegetable consumption. Adult household members ate less garden-grown produce than gardeners and had the lowest Pb intakes. Our results suggest that healthy gardening practices to reduce Pb exposure in urban community gardens should focus on encouraging cultivation of lower Pb vegetables (i.e., fruits) for adult gardeners and on covering higher Pb non-bed soils accessible to young children. However, the common practice of replacement of root-zone bed soil with clean soil (e.g., in raised beds) has many benefits and should also continue to be encouraged.
