The Environmental Health Study in the Korean National Industrial Complexes (EHSNIC) is a project that aims to monitor the exposure and health effects of environmental pollution among residents of national industrial complexes, as well as propose appropriate environmental health measures. Since its launch in 2003, this project has been initiated in eight national industrial complexes. Currently, it is necessary to review the accomplishments and limitations of the phases 1 and 2 of this project, and establish the direction of the upcoming the phase 3. Thus, the present study has developed principles and goals for the phase 3, considering the rationale and justification of the EHSNIC, and presented specific research contents accordingly. In the phase 3, it is important to improve the methods for exposure assessment and evaluation of health effects, in order to identify clearly the association between the pollutants released from industrial complexes and their health impacts, to develop and to reinforce communication strategies to promote participation of residents of communities near industrial complexes. Nonetheless, it is also important to maintain the basic goal of continuously monitoring the level of exposure to and health effects of environmental pollutants.

Background:
Coal is the largest source of energy on earth and is used to supply electricity in many countries. Unfortunately, as much as it helps light up some communities, coal-fired power plants are also the world's biggest industrial polluters.
Objectives:
This study investigated the environment and health conditions of the community before, and 20 years after the construction of the coal. It explored the perception of the respondents on the presence of a coal-fired power plant in their community, and determined strategies that can help protect the community against the coal-fired power plant.
Methodology:
It utilized descriptive phenomenological design using in-depth interviews through snowball
sampling. Data were analysed through Colaizzi method and was guided by the health belief model which
claims that change can occur if self-efficacy is built in.
Results:
Three themes emerged from the analysis: (1) realization of the deterioration of the environment and the residents' health, (2) awareness on the interplay between economic gain, politics, and impact on health and environment, and (3) recognizing the need for increased community empowerment on health and environment.
Conclusion
The presence of a coal-fired power plant in the community brings about negative changes in health and environment. Sustainable efforts to combat such negative effects are needed, and community residents in the vicinity of the power plant need to be empowered to conduct check-and-balance for their own health and environmental safety.

Wet detoxification has traditionally been seen as the most promising technology for treating chromium-contaminated sites. However, the addition of chemicals in the wet detoxification process not only increases the cost but also introduces extra pollutants. Moreover, the chromium-containing slag may be re-dissolved in the form of Cr(VI), and the increased concentration of Cr(VI) results in a serious "returning to yellow" phenomenon in the chromium-contaminated sites, causing undesirable secondary pollution. Microbial remediation is a promising technology to address the re-dissolution of chromium-containing slag after wet detoxification, and this article reviews the advances in this area. Firstly, the toxicity, current situation and conventional technologies for treating the chromium-containing slag were briefly summarized. The mechanisms of the inevitable re-dissolution of chromium-containing slag after wet detoxification were summarized. Three main mechanisms, namely bioreduction, biosorption and biomineralization, which are involved in the environmental-friendly and efficient microbial remediation technology, were reviewed. The variation of microbial species and the succession of microbial community during the bioremediation of chromium-contaminated sites were discussed. Finally, future research directions were prospected with the aim to develop long-term, stable and sustainable technologies for remediating the chromium-contaminated sites.

OBJECTIVEThe human socio-economic development depends on the planet's natural capital. Humans have had a considerable impact on the earth, such as resources depression and environment deterioration. The objective of this study was to assess the impact of socio-economic development on the ecological environment of Wuhan, Hubei Province, China, during the general planning period 2006-2020.
METHODSSupport vector machine (SVM) model was constructed to simulate the process of eco-economic system of Wuhan. Socio-economic factors of urban total ecological footprint (TEF) were selected by partial least squares (PLS) and leave-one-out cross validation (LOOCV). Historical data of socio-economic factors as inputs, and corresponding historical data of TEF as target outputs, were presented to identify and validate the SVM model. When predicted input data after 2005 were presented to trained model as generalization sets, TEFs of 2005, 2006,..., till 2020 were simulated as output in succession.
RESULTSUp to 2020, the district would have suffered an accumulative TEF of 28.374 million gha, which was over 1.5 times that of 2004 and nearly 3 times that of 1988. The per capita EF would be up to 3.019 gha in 2020.
CONCLUSIONSThe simulation indicated that although the increase rate of GDP would be restricted in a lower level during the general planning period, urban ecological environment burden could not respond to the socio-economic circumstances promptly. SVM provides tools for dynamic assessment of regional eco-environment. However, there still exist limitations and disadvantages in the model. We believe that the next logical step in deriving better dynamic models of ecosystem is to integrate SVM and other algorithms or technologies.

Cardiovascular disease (CVD) is the leading cause of mortality and healthy life expectancy loss, ranking first in causing the global burden of disease. In addition to the traditional CVD risk factors, such as hypertension and diabetes, environmental chemical pollutants may also play a role in the development of CVD. This paper summarizes the evidence regarding the relation of exposures to metal or metalloid and persistent organic pollutants with risk for CVD and introduces the research progress in the relation between the exposures to two environmental chemical pollutants and CVD risk. The study aims to provide scientific evidence for the effective prevention of CVD through the management of chemical pollutants in environment.

Context:
Exposure to environmental pollutants (EP) and Endocrine-disrupting chemicals (EDCs) is associated with several general negative health effects which compromise women's reproductive health, maternal, and neonatal outcomes. Unfortunately, many nonpregnant and pregnant women are unaware of their active exposure to these potentially slow-acting toxic substances, EPs, and EDCs. At any stage of life, and in the long-term minute exposures, there is no established safe level of exposure to these substances. Due to the potentially harmful effects on women in general, and to the pregnant and her unborn child in particular, it is important to establish the prevalence of their exposure.
Aims:
The aim of this study was to determine the magnitude (prevalence) of exposure among nonpregnant and pregnant women aged 18–49 years to common EPs/EDCs such as bisphenol A, pesticides, phthalates, and perfluorinated compounds among others.
Settings and Design :
This study was conducted at the Philippine General Hospital, University of the Philippines Manila.
Subjects and Methods :
The study participants were nonpregnant and pregnant women, with low-risk singleton pregnancy, and had a prenatal checkup and eventual delivery at the Philippine General Hospital. After consent, women were asked to answer a survey focused on their sociodemographics and frequency of exposure to EP- and EDC-containing items.
Satatistical Analysis Used:
Descriptive statistics were used to summarize the demographic and clinical characteristics of the patients. Null hypotheses were rejected at 0.05 α-level of significance. The computer software STATA 13.1 was used for data analysis.
Results:
One hundred and fifty-nine survey responses by women were analyzed. Possible EDC-containing household items (carpets, linoleum, upholstered, and stain-resistant furniture) are more prevalent in the homes of pregnant women compared to nonpregnant women. Pregnant women are also exposed to wallpapers compared to nonpregnant individuals. Nonpregnant women were 1.5 times more exposed to lotions. Unexposure to hand sanitizers is 1.3 times higher among pregnant individuals.
Conclusions
There are differences in the prevalence of exposure to household EDC-containing items between pregnant and nonpregnant women, with pregnant women having a higher prevalence of exposure.

The genus Dehalogenimonas (Dhgm) is a recently discovered taxonomic group within the class Dehalococcoidia of the phylum Chloroflexi. To date, Dhgm consists of three formally described species including Dehalogenimonas lykanthroporepellens, Dehalogenimonas alkenigignens and Dehalogenimonas formicexedens. All isolates of these three Dhgm species are obligate organohalide-respiring bacteria. They use hydrogen and formate as electron donors and chlorinated ethanes (e.g., 1,2,3-trichloropropane, 1,2-dichloropropane, 1,2-dichloroethane) as electron acceptors in energy-conserving reductive dechlorination reaction. Chlorinated ethanes are common groundwater contaminants in China. The unique metabolic capacities of Dhgm strains implicate it may play important roles in site remediation. The recently reported Dhgm sp. strain WBC-2 and 'Candidatus Dehalogenimonas etheniformans' strain GP are capable of dechlorinating certain chlorinated ethenes. More importantly, strain GP can completely detoxify the carcinogenic vinyl chloride (VC) to ethene. These findings expand the diversity of microorganisms involved in the respiratory VC reductive dechlorination and improve the understanding of Dhgm's ecological functions. Here, we summarize the advances in physiological and biochemical characteristics, ecological functions and genomic features of Dhgm, with the aim to develop effective and sustainable strategies to facilitate the bioremediation of chlorinated compounds contaminated sites.
