Analysing trace elements in baby food for children with celiac disease

Andrew Meharg, University of Aberdeen, and colleagues from Universidad Miguel Hernández have investigated a number of essential and toxic trace elements present in baby foods, looking particularly at the diet of infants with celiac disease. Although research into trace element availability has been undertaken before, most focus on only a few essential elements such as zinc and iron, and none have specially investigated the foods designed for infants suffering from celiac disease.

Meharg et al. examined gluten-free rice-based baby foods, baby cereals with gluten and puréed baby foods from Spain and compared these with baby foods produced in the US, UK and China for essential (Ca, Na, Fe, Cu, Mn, Zn, Se, Cr, Ni and Co) and non-essential (As, Pb, Cd and Hg) elements.  They found that baby cereals (which contain gluten) were richer in Ca, Fe, Cu, Mn, Zn, Cr and Ni than the gluten-free baby rice options and in line with other recent studies, they found that the content of As in rice-based foods was elevated.  The researchers also discuss the fortification of different baby foods with trace essential elements in line with WHO recommendaitons.

JEM author Dr Kevin Ashley presented Moyer D. Thomas Award

Dr Kevin Ashley from the Centers for Disease Control and Prevention, NIOSH, USA, was recently awarded the prestigious Moyer D. Thomas Award for his “outstanding contributions to the standardization of the sampling and analysis of atmospheres” from the ASTM International Committee D22 on Air Quality.

Dr Ashley is a senior research scientist at the U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), where he has worked since 1991.  His current research is working to evaluate and validate workplace air sampling techniques to improve sample collection and analysis aspects and to harmonize methods for occupational exposure assessment.

A regular author in JEM, some of Dr Ashley’s recent work on environmental atmospheric analysis was published as part of our issue from last year’s AIRMON conference:

Interlaboratory evaluation of trace element determination in workplace air filter samples by inductively coupled plasma mass spectrometry
Kevin Ashley, Stanley A. Shulman, Michael J. Brisson and Alan M. Howe
J. Environ. Monit., 2012,14, 360-367
DOI: 10.1039/C1EM10695C

Preparation, certification and interlaboratory analysis of workplace air filters spiked with high-fired beryllium oxide

Thomas J. Oatts, Cheryl E. Hicks, Amy R. Adams, Michael J. Brisson, Linda D. Youmans-McDonald, Mark D. Hoover and Kevin Ashley
J. Environ. Monit., 2012,14, 391-401
DOI: 10.1039/C1EM10688K

The Moyer D. Thomas award was established in 1975 and is awarded in recognition of outstanding achievement in the standardization of the sampling and analysis of atmospheres. It was last awarded in 2010, to George Luciw, by a task group of the Executive Committee of Committee D22 on Sampling and Analysis of Atmospheres.

Our congratulations to Dr Ashley on receiving this award.

HOT article: baseline element compositions of lichens in SW Patagonia, Chile

Fabrizio Monaci and co-workers at the University of Siena, Italy, and the University of Concepción, Chile, have measured the baseline element composition of two lichens (Nephroma antarcticum and Usnea sp.) growing in a remote region of SW Chilean Patagonia.

The team recorded the lowest concentrations of major and trace elements from lichens in the rainforest, and say that these concentrations can be used as background levels for the area. The authors believe these levels will be useful for detecting environmental change in the region, which will become more important in the coming months due to the construction of hydropower dams in the area.

Read more about the differences in composition between the different lichens and along the climatic gradient in the full article:

JEM Issue 8 online now

Journal of Environmental Monitoring coverThe latest issue of JEM is now online, featuring two HOT articles on the cover from Knut Breivik and Matthew Nonnenmann et al.

Knut Breivik and colleagues have developed a method to estimate the potential risks of organic chemical emissions emanating from commercial activities. No methods currently exist to quantitatively estimate the risks associated with such emissions and here the authors have sought to address this by developing an approach that looks at the quantities of organic chemicals used, their intended function and physical–chemical properties to estimate emissions to air, soil and water:

Screening organic chemicals in commerce for emissions in the context of environmental and human exposure
Knut Breivik, Jon A. Arnot, Trevor N. Brown, Michael S. McLachlan and Frank Wania
DOI: 10.1039/C2EM30259D

Matthew Nonnenmann et al have sought to overcome some of the limitations associated with culture-based techniques for identifying and quantifying fungi in environmental samples by using pyrosequencing.  Pyrosequencing offers the potential for discovering new fungal species, where are more traditional methods such as PCR and QPCR require known species to develop assays. The paper compares the two approaches in dust samples, where fungi may be associated with lung disease:

Utilizing pyrosequencing and quantitative PCR to characterize fungal populations among house dust samples
Matthew W. Nonnenmann, Gloria Coronado, Beti Thompson, William C. Griffith, John Delton Hanson, Stephen Vesper and Elaine M. Faustman
DOI: 10.1039/C2EM30229B

HOT article: the effects of the Ajka red mud spill on test species

This HOT article from Orsolya Klebercz and co-workers from Hungary and the UK discusses the ecotoxicity of fluvial sediments that resulted from the spillage of bauxite processing residue (red mud) in Ajka, Hungary.

The team carried out physico-chemical analyses on a number of samples taken from sites downstream of the spill. Biological characterisation and ecotoxicity testing was also carried out on a number of test species, including the Vibrio fischeri luminescence inhibition test, the Sinapis alba root and shoot growth inhibition test and the Heterocypris incongruens mortality test.

Adverse effects were recorded across a range of trophic levels at the different sample sites, although the microbial activity was shown to have increased. Lemna minor was shown to be a useful test species when assessing the impact of red mud contamination.

Read more about the study here – the paper is free to access for 4 weeks:

HOT article: Measuring the deposition of polycyclic aromatic hydrocarbons

This week’s HOT article is by Dieter Gladtke from the Landesamt für Natur, Umwelt und Verbraucherschutz Nordrhein-Westfalen and co-workers. In their paper, they present different collector types, sample workup procedures and analysis methods to measure the deposition of polycyclic aromatic hydrocarbons (PAH).

Whilst workup procedures and analysis methods had no effect on the results, the team found that using different collectors did have an influence. For compliance with European legislation, funnel–bottle combinations were shown to be the best, with the highest deposition rates and a low measurement uncertainty.

JEM Emerging Investigators 2012

Our latest issue is dedicated to Emerging Investigators – highlighting the research of the best and brightest young minds in environmental science and engineering. This is the third year we have produced an issue dedicated to new researchers to the field, and we are delighted that 2010 Emerging Investigators David Cwiertny and Tamar Kohn guest edited this issue with us.

David Cwiertny and Tamar Kohn discuss the unique nature of the young environmental science field in their editorial and the challenges facing new researchers, from marketing work to funding agencies to communicating science to the public.

The issue contains plenty of HOT research, including fluvial transport of arsenic, groundwater contamination at an ex-uranium mine, Cr VI formation during chlorination of drinking water, interactions of organic matter and gold nanoparticles, effect of water treatment on antibiotic resistance and improving the measurement accuracy for water-soluble composition of PM2.5.
