“…Here, urinary total mercury levels were higher among mothers and children residing on-Reserve than off-Reserve. A similar relationship was found among adults residing at varying distances from an active chlor-alkali plant in Poland (Jarosinska et al, 2006). Average concentrations found among and near Aamjiwnaang were above those seen in Poland for both the chlor-alkali and reference zones (mean chlor-alkali =0.40 μg/L, mean reference = 0.21 μg/L).…”

An Ecological and Human Biomonitoring Investigation of Mercury Contamination at the Aamjiwnaang First Nation

The Aamjiwnaang First Nations community is located in Canada’s ‘Chemical Valley’ situated in southwest Ontario near Sarnia. Mercury pollution in the region has been known since the 1940s but little is known about levels in the environment and area residents. The current study, using ecological and human exposure assessment methods, was conducted at the community’s request to help fill these gaps. First, Canada’s National Pollutant Release Inventory (NPRI) and the U.S. Toxics Release Inventory (TRI) were queried to investigate mercury releases from area facilities. In 2010, 700 pounds of mercury were emitted into the air, 25 pounds were released into water bodies, and 93 thousand pounds were disposed of on-site via underground injections or into landfills, and together these show continued releases into the region. Second, mercury levels were measured in stream sediment and nearby soil from sites at Aamjiwnaang (n=4) and off Reserve (n=19) in Canada and the U.S. during three seasons that spanned 2010–2011. Total mercury in sediment across all sites and sampling seasons ranged from 5.0 to 398.7μg/kg, and in soils ranged from 1.2 to 696.2μg/kg. Sediment and soil mercury levels at Aamjiwnaang were higher than the reference community, and Aamjiwnaang’s Talfourd Creek site had the highest mercury levels. Third, a biomonitoring study was performed with 43 mother-child pairs. Hair (mean±SD of all participants: 0.18±0.16μg/g) and blood (1.6±2.0μg/L) mercury levels did not differ between participants studied on- and off-Reserve, likely because of limited seafood intake (<1 serving/week). Urine mercury levels (0.5±0.8μg/L) were significantly higher (1.5–2.5 times) in mother-child pairs living on-Reserve versus those living off-Reserve. In general, the study links evidence of mercury sources, environmental fate, and human exposures, and in doing so it shows that mercury levels in ecological and human samples are similar to values found in other areas, though there are some trends and evidence of contamination at Aamjiwnaang that warrant attention.

“…In contrast to other parts of the world where plants have shifted to new Hg‐free technologies, approximately one‐third of chlorine and alkali in Europe is still produced using Hg cells . Mercury exposures among people living near chlor‐alkali plants in Europe depend on many factors, including Hg concentrations in the air, dietary habits, and combined exposures from other environmental sources . In regions contaminated from Hg mining, aquatic biota can contain elevated levels of MeHg, and Hg is transferred from soil to vegetation , to herbivores, and to carnivores up the food chain , making food consumption an important route of Hg exposure for the local population.…”

The effects of human exposure to mercury (Hg) and its compounds in Europe have been the focus of numerous studies that differed in their design, including recruiting different population groups at different levels of exposure and using different protocols and recruitment strategies. The objective of the present study was to review current studies of Hg exposure in Europe, taking into account the potential routes of Hg exposure, actual Hg exposure levels assessed by different biomarkers, and the effects of Hg to Europeans. All published studies from 2000 onward were reviewed, and exposure and effects studies were compared with known Hg levels in environmental compartments by mapping the various population groups studied and taking into account known sources of Hg. A study of the spatial distribution trends confirmed that the highest exposure levels to Hg, mostly as methylmercury (MeHg), are found in coastal populations, which consume more fish than inland populations. Fewer studies addressed exposure to elemental Hg through inhalation of Hg in air and inorganic Hg in food, particularly in highly contaminated areas. Overall, at the currently low exposure levels of Hg prevalently found in Europe, further studies are needed to confirm the risk to European populations, taking into consideration exposure to various Hg compounds and mixtures of stressors with similar end-points, nutritional status, and a detailed understanding of Hg in fish present in European markets.

“…Urine samples in the present study were collected from Swedish men (n = 140), aged 20-60 years (mean = 43 years), participating in the EU-funded, "EMECAP" (European Mercury Emissions from Chloralkali Plants) project (Barregard, Horvat et al 2006;Jarosinska, Barregard et al 2006). Whilst the primary purpose of that project was to quantify the internal dose of mercury in chloralkali workers and general populations living close to mercury cell chloralkali plants, this population presented the opportunity to compare multiple methods of analysing urinary 8-oxodG.…”

Urinary 8-oxo-7,8-dihydro-2"-deoxyguanosine (8-oxodGuo) is widely used as a marker of oxidative stress. Herein we report the comparison of two, distinct chromatographic assays, with ELISA. Chromatographic assays displayed good agreement (r = 0.89, p < 0.0001), whereas there was markedly worse, albeit still significant, agreement with ELISA (HPLC-GC/MS: r=0.43, HPLC-EC: r=0.56; p<0.0001). Mean values differed significantly between chromatographic assays and ELISA (HPLC-GC/MS: 3.86, HPLC-EC: 4.20, ELISA: 18.70 ng/mg creatinine, p<0.0001). Whilst it is reassuring to note good agreement between chromatographic assay, this study reveals significant short-comings in the ELISA, which bring into question its continued use in its present form.
