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. 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.

  • Platinum in PM2.5 of the metropolitan area of Mexico City 2014-10-01

    Abstract

    The increase in platinum (Pt) in the airborne particulate matter with size ≤2.5 µm (PM2.5) in urban environments may be interpreted as result of the abrasion and deterioration of automobile catalyst. Nowadays, about four million vehicles in Mexico City use catalytic converters, which means that their impact should be considered. In order to evaluate the contribution of Pt to environmental pollution of the metropolitan area of Mexico City (MAMC), airborne PM2.5 was collected at five different sites in the urban area (NW, NE, C, SW, SE) in 2011 during April (dry-warm season), August (rainy season) and December (dry-cold season). Analytical determinations were carried out using a ICP-MS with a collision cell and kinetic energy discrimination. The analytical and instrument performance was evaluated with standard road dust reference material (BCR-723). Median Pt concentration in the analyzed particulate was is 38.4 pg m−3 (minimal value 1 pg m−3 maximal value 79 pg m−3). Obtained Pt concentrations are higher than those reported for other urban areas. Spatial variation shows that SW had Pt concentration significantly higher than NW and C only. Seasonal variation shows that Pt median was higher in rainy season than in both dry seasons. A comparison of these results with previously reported data of PM10 from 1991 and 2003 in the same studied area shows a worrying increase in the concentration of Pt in the air environment of MAMC.

  • Urinary arsenic levels influenced by abandoned mine tailings in the Southernmost Baja California Peninsula, Mexico 2014-10-01

    Abstract

    Gold has been mined at San Antonio-El Triunfo, (Baja California Sur, Mexico) since the 18th century. This area has approximately 5,700 inhabitants living in the San Juan de Los Planes and El Carrizal hydrographic basins, close to more than 100 abandoned mining sites containing tailings contaminated with potentially toxic elements such as arsenic. To evaluate the arsenic exposure of humans living in the surrounding areas, urinary arsenic species, such as inorganic arsenic (iAs) and the metabolites mono-methylated (MMA) and di-methylated arsenic acids (DMA), were evaluated in 275 residents (18–84 years of age). Arsenic species in urine were analyzed by hydride generation-cryotrapping-atomic absorption spectrometry, which excludes the non-toxic forms of arsenic such as those found in seafood. Urinary samples contained a total arsenic concentration (sum of arsenical species) which ranged from 1.3 to 398.7 ng mL−1, indicating 33 % of the inhabitants exceeded the biological exposition index (BEI = 35 ng mL−1), the permissible limit for occupational exposure. The mean relative urinary arsenic species were 9, 11 and 80 % for iAs, MMA and DMA, respectively, in the Los Planes basin, and 17, 10 and 73 %, respectively, in the El Carrizal basin. These data indicated that environmental intervention is required to address potential health issues in this area.
