SEGH Journal Impact Factor News

03 August 2014
The Society's journal Environmental Geochemistry & Health (EGAH), received good news recently with the announcement of a significant increase in its impact factor, now reaching 2.573.

The editor in Chief, Professor Ming Hung Wong, sent the following message to SEGH members:

 

I am very pleased with the new impact factor which indicated the articles included in our EGAH are interesting, important and timely. The past few years, we have received an increasing number of high quality papers from more countries, addressing various current issues on environmental geochemistry of elements and their environmental and human health. There is no doubt that EGAH will scale new height in the very near future, judging from the momentum we have experienced the past few years.

May I use this opportunity to thank our publisher at Springer, Betty and Paul for their continuous guidance, Andrew (Hursthouse) and members of SEGH board’s contribution in shaping the future directions of EGAH, the coordinating editors for overseeing papers assigned to them, and the reviewers for commenting on the papers. I sincerely hope that you will continue to support EGAH by serving on the board, and serving as reviewers. Nevertheless, most important of all, send your high quality papers to EGAH.

Best wishes

Ming Hung Wong,

Editor in Chief, Environmental Geochemistry & Health

 

On behalf of the SEGH board I would also like to record our thanks to Springer staff and in particular personal best wishes to Betty Van Herk, who retired from Springer on 31st July 2014. Betty and her colleagues have supported SEGH over many years, beyond the role of publishing the journal by discussing SEGH conference themes and topics to help raise both the Society and Journal profile. A great team and part of a wider SEGH “family”. Our conferences continue to be successful and popular, organised with great enthusiasm and good scientific focus. It is wonderful to see this translating into high quality papers with increasing impact.  Don't forget, you can access EGAH and its back catalogue through www.segh.net as a full member of SEGH.

  • Genotoxic effects of PM 10 and PM 2.5 bound metals: metal bioaccessibility, free radical generation, and role of iron 2018-10-09

    Abstract

    The present study was undertaken to examine the possible genotoxicity of ambient particulate matter (PM10 and PM2.5) in Pune city. In both size fractions of PM, Fe was found to be the dominant metal by concentration, contributing 22% and 30% to the total mass of metals in PM10 and PM2.5, respectively. The speciation of soluble Fe in PM10 and PM2.5 was investigated. The average fraction of Fe3+ and Fe2+ concentrations in PM2.5 was 80.6% and 19.3%, respectively, while in PM2.5 this fraction was 71.1% and 29.9%, respectively. The dominance of Fe(III) state in both PM fractions facilitates the generation of hydroxyl radicals (·OH), which can damage deoxyribose nucleic acid (DNA), as was evident from the gel electrophoresis study. The DNA damage by ·OH was supported through the in silico density functional theory (DFT) method. DFT results showed that C8 site of guanine (G)/adenine (A) and C6 site of thymine (T)/cytosine (C) would be energetically more favorable for the attack of hydroxyl radicals, when compared with the C4 and C5 sites. The non-standard Watson–Crick base pairing models of oxidative products of G, A, T and C yield lower-energy conformations than canonical dA:dT and dG:dC base pairing. This study may pave the way to understand the structural consequences of base-mediated oxidative lesions in DNA and its role in human diseases.

  • A systematic review on global pollution status of particulate matter-associated potential toxic elements and health perspectives in urban environment 2018-10-08

    Abstract

    Airborne particulate matter (PM) that is a heterogeneous mixture of particles with a variety of chemical components and physical features acts as a potential risk to human health. The ability to pose health risk depends upon the size, concentration and chemical composition of the suspended particles. Potential toxic elements (PTEs) associated with PM have multiple sources of origin, and each source has the ability to generate multiple particulate PTEs. In urban areas, automobile, industrial emissions, construction and demolition activities are the major anthropogenic sources of pollution. Fine particles associated with PTEs have the ability to penetrate deep into respiratory system resulting in an increasing range of adverse health effects, at ever-lower concentrations. In-depth investigation of PTEs content and mode of occurrence in PM is important from both environmental and pathological point of view. Considering this air pollution risk, several studies had addressed the issues related to these pollutants in road and street dust, indicating high pollution level than the air quality guidelines. Observed from the literature, particulate PTEs pollution can lead to respiratory symptoms, cardiovascular problems, lungs cancer, reduced lungs function, asthma and severe case mortality. Due to the important role of PM and associated PTEs, detailed knowledge of their impacts on human health is of key importance.

  • Interactions between polycyclic aromatic hydrocarbons and epoxide hydrolase 1 play roles in asthma 2018-10-06

    Abstract

    Asthma, as one of the most common chronic diseases in children and adults, is a consequence of complex gene–environment interactions. Polycyclic aromatic hydrocarbons (PAHs), as a group of widespread environmental organic pollutants, are involved in the development, triggering and pathologic changes of asthma. Various previous studies reported the critical roles of PAHs in immune changes, oxidative stress and environment–gene interactions of asthma. EPHX1 (the gene of epoxide hydrolase 1, an enzyme mediating human PAH metabolism) had a possible association with asthma by influencing PAH metabolism. This review summarized that (1) the roles of PAHs in asthma—work as risk factors; (2) the possible mechanisms involved in PAH-related asthma—through immunologic and oxidative stress changes; (3) the interactions between PAHs and EPHX1 involved in asthma—enzymatic activity of epoxide hydrolase 1, which affected by EPHX1 genotypes/SNPs/diplotypes, could influence human PAH metabolism and people’s vulnerability to PAH exposure. This review provided a better understanding of the above interactions and underlying mechanisms for asthma which help to raise public’s concern on PAH control and develop strategies for individual asthma primary prevention.
