a group of three isomeric volatile organic
compounds (VOCs) can come from many sources, from
petroleum and combustion, to cleaning agents and
plastics1. Chronic and acute exposure to xylenes through
multiple exposure routes has been linked to an assortment
of adverse health effects2,3,4,5,6,7,8. With a high number of
VOCs being released from structural fires, firefighters
could potentially face an occupational risk in responding to
fires due to potential acute and chronic exposure effects9.
Characterizing xylenes exposure in structural firefighters
can provide a greater understanding into the
occupational risk that xylenes pose to those who could be
exposed at a higher frequency.

Firefighters provide critical services to communities around the world despite the occupational hazards that they face. One such hazard, is exposure to a suite of chemicals released during a fire. In particular, polychlorinated biphenyls (PCBs) are a concerning class of chemicals, which persist in older building materials and electrical equipment (e.g. transformers). PCBs are recognized as endocrine disruptors, carcinogens, and developmental toxicants. Furthermore, some studies have shown structural firefighters to have elevated levels of PCBs in their serum. In this study, silicone passive samplers similar to military dog-tags worn around the neck were used to measure the bioavailable fraction of PCBs firefighters were exposed to while on- and off-duty. The dog-tags were worn by firefighters for a total of 30 24- hour shifts (n=57). These firefighters were from two different stations in the Kansas City metropolitan area, one of which had fewer than two calls to respond to per month on average (low call volume), and one that had more than 12 calls per month on average (high call volume). Additional questionnaire data was collected on number of fire attacks an individual participated in, demographics, and lifestyle information that might influence chemical exposures. The dog-tags were extracted using solvent and underwent solid phase extraction prior to instrumental analysis. Gas chromatography - mass spectrometry (GC-MS) was used to analyze the extracts for 43 PCB congeners. PCBs were detected in sample extracts from 16 different firefighters, 12 of which were from the high call volume station. Out of 12 detected congeners, PCB 153 was the most frequently detected. Statistical analyses will be used to assess whether PCB concentrations were higher at the high versus low call volume department and while on- compared to off-duty. Finally, we will explore correlation between questionnaire data such as number of fire attacks, and firefighters’ individual PCB exposures. Although firefighters may be exposed to increased levels of PCBs in house fires, few studies have monitored these exposures. There are even fewer studies that measure dermal exposure, even though PCBs are known to be absorbed through and distributed to the skin. Given the hazards posed by PCBs, it is critical that we better understanding individual firefighters’ exposures to PCBs while on- and off-duty.

Abstract:

Chemical fate is a concern at environmentally contaminated sites, but characterizing that fate can be difficult. An important component of characterizing fate is identifying and quantifying the movement of chemicals at the air-water interface.  Superfund sites are often suspected sources of air pollution due to legacy sediment and water contamination. A quantitative assessment of polycyclic aromatic hydrocarbon (PAH) and oxygenated PAH (OPAH) diffusive flux in a river system that contains a Superfund Mega-site, and passes through residential, urban and agricultural land, has not been reported before. Here, passive sampling devices (PSD) were used to measure 60 polycyclic aromatic hydrocarbons (PAHs) and 22 oxygenated PAHs (OPAHs) in the air and water. Human health risk associated with inhalation of vapor phase PAHs and dermal exposure to PAHs in water were assessed. Excess lifetime cancer risk estimates show potential increased risk at sites within and in close proximity to a Superfund Mega-site. Specifically, estimated excess lifetime cancer risk associated with inhaling PAHs was above 1 in 1 million within the Superfund Mega-site. We show the majority of PAHs and some OPAHs in the water are from airborne sources. The majority of PAHs detected in both environmental compartments, 16 out of 26, the direction of mass transfer at all five study sites was deposition. This suggests that the river water in this Superfund site is predominantly a sink for airborne PAHs and OPAHs, rather than a source.

Epidemiological studies linking environmental exposures to health outcomes have been criticized for the lack of personal exposure data. The mobile exposure device (MED) is integrated personal environmental exposure tools coupled with software which links health data to location and chemical exposure. The MED combines a wristband passive sampling device with a smart phone application and biometric equipment providing a holistic tool to capture uniquely linked environmental-health information.  Silicone passive sampling wristbands sequester organic compounds while a cell phone application captures geographic location of study participants. Users were prompted to test lung function with a spirometer three times daily to identify variation in lung function throughout a typical daily routine.  Wristbands were worn daily then mailed to the laboratory, extracted, and analyzed for over 1,200 organic compounds including PAHs, OPAHs, PCBs, pesticides, flame retardants and industrial chemicals. Data is transmitted securely from a laboratory information management system and the smart phone app to a secure server through web services and integrated in order to discover statistical relationships among air pollutants, locations, and lung function. The MED was developed and tested in two different exposure scenarios, one community in Oregon with proximity to intense industrial activity, and another community in Ohio near unconventional natural gas drilling operations. Focus group meetings were employed in both communities to further enhance and optimize the MED. Early beta testing resulted in a daily accumulation of over 600,000 data points including geographic location, lung function, and chemical observations for each participant. The MED coupled with data integration and visualization techniques will enable researchers  to gain new insights and investigate new connections, while allowing communities to see their data in more intuitive ways.

Passive sampling devices were used to measure the air vapor phase and water dissolved phase at four Gulf of Mexico coastal sites. Sampling occurred prior to, during and after shoreline oiling concurrent with the Deepwater Horizon oil spill.  Measurements of 33 polycyclic aromatic hydrocarbons (PAHs) and 22 oxygenated PAHs (OPAHs) were taken across all time points and sites, and flux across the water/air boundary was determined.  While aqueous PAH concentrations have been previously reported, all air concentrations are some of the first to represent both vapor phase PAHs and OPAHs during the Deepwater Horizon incident.  The largest vapor phase Σ33airPAH concentrations in air were 24.1ng/m3 in Gulfport, MS during May 2010 and 22.7ng/m3 in Grand Isle, LA during June of the same year. The largest Σ22OPAH vapor phase concentrations in air were 26.6ng/m3 in Gulf Breeze, Florida during May 2010 and 20.6 in Gulfport, MS in May 2010.  Concentrations in May represented air data prior to shoreline oiling. The direction and magnitude of the time-integrated air-water exchange of 13 individual PAHs were strongly influenced by the Deepwater Horizon oil incident.  The largest Σ13 PAH volatilization was 11,200 ng/m2/day and occurred in Gulf Shores, AL in September 2010, with the largest individual PAH volatilization to air was acenapthene at a rate of 6,820ng/m2/day during the same deployment.  This work represent additional evidence of contamination during the Deepwater Horizon oil spill, but provides one of the first examples of flux determination with passive sampling data. In addition to impacting marine waters, the introduction of this volume of oil into this ecosystem combined with the combustion of this material had quantifiable impacts on Gulf of Mexico air chemistry and quality.

Polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) are persistent organic compounds that continue to drive risk management efforts. In order to characterize exposure pathways and assess human health risks associated with consumption of contaminated resident fish, regulatory agencies conventionally analyze homogenized fish tissue samples for PAHs and PCBs. However, obtaining fish for analysis is challenging, the analysis is destructive, and the analysis offers limited spatial and temporal information due in part to biological and physiological variability. For these reasons, an alternative tool capable of accurately predicting fish tissue contaminant levels would be useful to regulatory agencies and risk managers.

Passive sampling devices (PSDs) sample the bioavailable fraction of chemicals, are readily available in large numbers, provide a non-destructive sampling method, yield simpler chemicals analyses, and are capable of identifying spatial and temporal contamination patterns. We hypothesize that PSDs are capable of providing site-independent predictions of chemical load in aquatic tissues with useful accuracy. To test this, PSDs were deployed in the water column at 8 different sites within and outside of the Portland Harbor Superfund Megasite for 24 days. Simultaneously, nearly 100 resident crayfish were collected. Sites selected for PSD and crayfish sampling represented a wide range of PAH and PCB concentrations. PSDs and crayfish were then analyzed for 16 priority pollutant PAHs and 32 dioxin and non-dioxin like PCB congeners using a novel analytical method. Presented results will include regression analyses on total contaminant loads (ΣPAH + PCBs), chemical class specific loads (ΣPAHs, ΣPCBs), and individual contaminant of concern loads. Additionally, we will determine PSD-crayfish specific bioaccumulation factors (BAFPSD-CF) for a wide suite of contaminants of concern. PAH and PCB PSD loads will subsequently be used as surrogates for crayfish and used to generate human health risk estimates. Estimates will then be compared to risk results reported in the Portland Harbor Public health assessment for consumption of impacted resident crayfish. Results from this study will help identify novel PSD applications that could provide useful information to regulators and risk managers.

Environmental and occupational exposure to nickel is generally well characterized, however other potential routes of exposure,such as leaching from stainless steel cookware are not well known. Nickel occurs naturally in plants and animals, and humans are exposed to it from these dietary sources. Humans are estimated to ingest an average of 150 to 900μg of nickel per day. In 2001, the Tolerable Upper Intake Level (UL) of nickel was decreased to 1000μg per day. The toxicological studies of nickel indicate that single oral doses as low as 3000μg causes allergic dermatitis. It is recommended that individuals sensitive to nickel lower their exposure. However, nickel may be introduced to the diet via leaching from stainless steel cookware into foods during cooking processes, contributing to flare-ups of allergic contact dermatitis. We tested three variables, grade of stainless steel, cook time, and repeated usage or cooking cycles, for their effects on nickel leaching from stainless steel during the process of cooking tomato sauce. Sampling involved simulated home cooking procedures with stainless steel grades equivalent to those found in cookware. After the cooking procedure samples underwent acid digestion, and analysis using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). Results show significant differences in nickel leaching between grades of stainless steel, indicative of the reported protective properties of the chromium oxide film in stainless steel. The amount of nickel in tomato sauce increased from 4.99mg/kg after a cook time of two hours to 7.63mg/kg after a cook time of twenty hours. The first cooking cycle showed the highest nickel concentration of 5.76mg/kg. Sequential cooking cycles with the sample stainless steel resulted in decreasing amounts nickel leached with each subsequent cooking cycle. From this set of experiments we can conclude that in addition to dietary exposures, stainless steel comparable to cookware is a source of nickel. Nickel exposure from stainless steel is variable, and dependent on grade of steel,cook time, and number of cooking cycles.

Organizations and developing countries that attempt to assess pesticides and other environmental contaminants face many challenges of how to measure them, such as, the remoteness of sites and subsequently the difficulty of transportation and stability of chemicals in samples from these sites.  The Sahel region of Western Africa has many highly engineered agriculture-based irrigated systems that generally have three cropping cycles per year.  The need to assess changes in contaminants at these sites requires tools that can characterize contaminants at high spatial and temporal resolution.  Modification of farming pest management practices face the challenge of how to measure success; how to assess the changes in bioavailability of contaminants.  They need quantitative tools that can characterize contaminants and predict their risk to local organisms and humans.  To address these issues we have further developed passive sampling devices (PSDs) that can sequester thousands of bioavailable chemicals.  These devices can help organizations and developing countries to evaluate changes in pest management that may produce or release chemicals.  PSDs can help organizers characterize exposure more accurately.  We are using PSDs to capture relevant non-polar and semi-polar pesticides and other chemicals of interest at multiple sites in Western Africa.  PSDs do not require power, transport easily and are easily extracted with organic solvent. We deployed PSDs in irrigation canals at seven agricultural sites in Senegal, Mali, and Mauritania agricultural stations. We were able to screen the PSD extracts for nearly 1,200 potential contaminants with gas chromatography mass spectrometry through the use  of libraries we have further developed based on software, including automated compiled mass spectral de-convolution and identification system libraries that contain numerous classes of chemicals of concern (pesticides, PCBs, PAHs, pharmaceuticals, industrially related chemicals, etc.). The results for all sites combined showed positive hits of six PCB congeners, 11 pesticides, 21 PAHs and two legacy pesticides including ethiolate, p’p’ DDD and its breakdown products.  Furthermore the compound pentachloroanisole a breakdown product of pentachlorophenol was detected in Mauritania. PSDs coupled with GC-MS screening tools offer a powerful technology to identify persistent organic pollutants present at agricultural sites in three countries in the Sahel region of Western Africa.

Regulatory agencies are required to mitigate human and ecological exposure to toxic chemicals of concern. In order to meet this demand, chemical drivers of toxicity and accurate exposure pathways must be identified. Though mixtures are complex systems, it has been postulated that the bioavailable fraction of mixtures is linked to toxicity. Applying additional stressors to chemical mixtures will likely transform the composition of the bioavailable fraction and induce differential toxicological responses. In order to more accurately characterize exposure, regulatory agencies need experimental approaches that can determine the effect of natural/remediation processes on the bioavailable fraction of chemical mixtures and mixture toxicity.

Passive sampling devices (PSDs) readily sequester the bioavailable fraction of environmentally relevant mixtures, which includes polycyclic aromatic hydrocarbons (PAHs). We hypothesized that perturbations of PSD extracts via UV light exposure could reduce concentrations of PAHs and simultaneously increase concentrations of currently unmonitored oxygenated polycyclic aromatic hydrocarbons (oxy-PAHs). PSD samples collected from the Portland Harbor Superfund Megasite and the waters of the Gulf of Mexico following the Deepwater Horizon oil disaster were exposed to UV light (λ = 313 nm) for 30 minutes at an irradiance roughly 30-40 times greater than a single sunny day in Northern US cities. Along with PSD samples, 1 ppm standard mixtures of 16 EPA priority pollutant PAHs were also exposed. PAHs and 22 oxy-PAHs were quantified in pre- and post-UV exposed samples using a recently expanded and validated GC-MS analytical method. It was found that the concentration of nearly half of the monitored PAHs were significantly reduced in standard mixtures following UV exposure, while levels of 9,10-anthraquinone and 7,12-benz[a]anthracenequinone were increased by roughly an order of magnitude relative to controls. Similar results were observed in environmentally relevant PSD samples. Combining PSD technology with other environmental stressors could provide a powerful approach for identifying emerging chemicals of concern, accurate exposure pathways, and chemical drivers of toxicity.

Although communities often want and need chemical monitoring data to characterize chemicals in their environmental or from their activities, air monitoring equipment is often cost prohibitive or technically impractical.   We are further developing air monitoring bio-analytical tools that employ our passive sampling device (PSD).  PSDs require no external power, require minimal training for quality controlled sampling, and can be quickly and inexpensively deployed.  PSD are capable of providing qualitative and quantitative characterization of exposure to the bioavailable vapor phase fraction of legacy and emerging contaminants in the atmosphere. We demonstrate our PSD’s utility in three vastly different scenarios; before, during and after the Gulf of Mexico Deepwater Horizon oil spill in spring of 2010, at the interface of community tribal lands and high intensity industrial activities, and finally in Native American fish smoking activities.  Legacy and emerging PAHs were characterized for all three scenarios; analysis of PSD extracts using a 1,200 analyte screening method was also undertaken.  Acute chemical spills generally require a quick response, and often there is a significant, or unknown, exposure prior to elaborate air monitoring equipment setup.  We deployed air PSDs prior to, during and after shoreline oiling from the Gulf of Mexico Deepwater Horizon oil spill of 2010 in Louisiana, Mississippi, Alabama and Florida.  Emerging and legacy polycyclic aromatic hydrocarbons (PAHs) were quantified in the air PSD. PSDs were also screened for an additional 1,200 contaminants of concern.  We demonstrate the utility of the air PSD to respond to acute chemical spills, and to gather chemical data sets on a wide range of contaminants. Communities adjacent to highly industrialized lands often want to understand the contribution of contaminants of concern from industrial activities to their ambient activities.  The Swinomish Indian Tribal Community (SITC) offered their lands to further test our developing air PSD technology and to address these kinds of questions.  PSD were deployed at SITC, which borders a petroleum facility, continuously for a yearlong study, from these PSD samples legacy and emerging PAHs were identified and quantified.  The results indicate spatial and temporal trends that were related to the activities of the tribal community and the petroleum facility.  While PSDs have been demonstrated as a surrogate of fish for aquatic environment assessment, atmospheric PSDs have not been previously used as a surrogate of food for preparation technique assessment.  Community-based requests often include understanding the effects of special food preparations that are culturally important.  The Confederated Tribes of the Umatilla Indian Reservation (CTUIR) requested an assessment of their fish smoking methods.  As part of a larger study, we deployed air PSDs during the CTUIR smoking events to further evaluate the utility of using our PSD as a surrogate of smoke-processed fish.  In a side-by-side study the PSDs were paired with salmon during smoking.  PAHs were quantified from the air PSD and compared with the smoked salmon.  The results show excellent promise for an alternative method for assessing food smoking preparation techniques. Throughout these three studies the OSU SRP Research Translation and Community Engagement Cores partnered to develop culturally appropriate messages and data interpretation including workshops, print materials, brochures, and web-based information.

Re-circulating aquaculture systems may occasionally become contaminated or amplify biological or chemical agents. For instance, increased prevalence of intestinal cancers have been observed in some zebrafish re-circulating aquaculture facilities. The etiology of these neoplasms are unknown. We used passive sampling devices in re-circulating aquaculture systems to sequester a suite of non-polar and semi-polar contaminants. Passive sampling devices sequester and concentrate a wide range of contaminants that may be at very low concentrations within a system, thus are well suited to investigate contamination and episodic exposure events. Through the use of Agilent's Retention Time Locking software, Deconvolution Reporting Software and combining several mass spectral libraries, we were able to screen the passive sampling device extracts for nearly 2000 potential contaminants with gas chromatography mass spectrometry. Included in our screen were over 900 pesticides and endocrine disruptors, PCBs, along with a wide range of other chemicals. The passive sampling device extracts were also used with the embryonic zebrafish toxicity model where fish were grown out to determine if similar types of cancer formed.
