In vitro screening of metal oxide nanoparticles for effects on neural function using cortical networks on microelectrode arrays

Nanoparticles (NPs) may translocate to the brain following inhalation or oral exposures, yet higher throughput methods to screen NPs for potential neurotoxicity are lacking. The present study examined effects of 5 Ce02 (5- 1288 nm), and 4 Ti02 (6-142 nm) NPs and microparticles (MP) on network function in primary cultures of rat cortex on 12 well microelectrode array (MEA) plates. Particles were without cytotoxicity at concentrations ≤ 50 μg/ml. After recording 1h of baseline activity prior to partide (3-50 μg/ml) exposure, changes in the total number ofspikes (TS) and # of active electrodes (#AEs) were assessed 1, 24, and 48 h later. Following the 48 h recording, the response to a challenge with the GABAA antagonist bicuculline (BIC; 25μM) was assessed. In all, particles effects were subtle, but 69 nm Ce02 and 25 nm Ti02 NPs caused concentration-related decreases in TS following 1 h exposure. At 48 h, 5 and 69 nm Ce02 and 25 and 31 nmTi02 decreased #AE, while the two MPs increased #AEs. Following BIC, only 31 nm Ti02 produced concentration-related decreases in #AEs, while 1288 nm Ce02 caused concentration-related increases in both TS and #AE. The results indicate that some metal oxide particles cause subtle concentration-related changes in spontaneous and/or GABAA receptor-mediated neuronal activity in vitro at times when cytotoxicity is absent, and that MEAs can be used to screen and prioritize nanoparticles for neurotoxicity hazard.

Measurements of Oil and Natural Gas Well Pad Enclosed Combustor Emissions Using Optical Remote Sensing Technologies

The U.S. Environmental Protection Agency (EPA), Office of Research and Development (ORD) and EPA Region 8 are collaborating under the EPA’s Regional Applied Research Effort (RARE) program to evaluate ground-based remote sensing technologies that could be used to characterize emissions from enclosed combustion devices (ECD) at upstream oil and natural gas well pads. This paper describes a 5-day pilot study executed by ARCADIS in September 2014 to remotely observe emissions from ECDs at multiple well pads in Weld County Colorado using a passive Fourier transform infrared radiometer, and a mid-wave infrared hyper-spectral imager. The goals of the study were to evaluate the measurement technologies, provide speciated emissions information, and to assess the combustion efficiency (CE) of the ECDs. A total of 10 well pads were surveyed during the campaign. This paper describes the measurement systems, field deployment methods, and select results from the study. In general, the remote sensing approaches were found to be potentially useful as a research tool for offsite observation of ECD operation if more direct onsite measures are not available. Limitations were found in ease of execution, data analysis throughput, and observable ECD temperature ranges. Of the 10 sites observed, two sites had ECDs that could not be measured due to insufficient infrared signal caused by overall low combustion throughput (resulting in low temperature of the ECD). With uncertainties in CE accuracy noted, seven of the 8 measurable sites showed ECD CEs generally exceeding 95%. One site showed higher emissions of several alkanes and alkenes, with CE values calculated to be as low as 0.60.

Remote and Onsite Direct Measurement of Emissions from Oil and Natural Gas Production

Environmentally responsible oil and gas production requires accurate knowledge of emissions from long-term production operations1, which can include methane, volatile organic compounds, and hazardous air pollutants. Well pad emissions vary based on the geologically-determined composition of the product, production rates, age of the well, production equipment design, and maintenance states of systems and emission control devices. Well pad emissions can be difficult to measure and model due to the large number of potential sources. This extended abstract expands current knowledge of VOC and HAP well-pad emissions through comparison of several studies spanning a variety of measurement approaches. New data from an EPA onsite study and a series of remote mobile surveys are compared with four previous onsite studies.

Performance Evaluation and Quality Validation System for Optical Gas Imaging Cameras that Visualize Fugitive Hydrocarbon Gas Emissions

A U.S. EPA team, consisting of the Office of Research and Development and Region 6 (Dallas) and Region 8 (Denver), deployed passive-diffusive sorbent tubes as part of a method evaluation study around one oil and natural gas production pad in both the Barnett Shale Basin in Texas and the Denver-Julesburg Basin in Colorado to measure speciated volatile organic compounds (VOCs). EPA Draft Methods 325A and 325B, which focus on low-cost measurement and analysis of fenceline concentrations of benzene near refineries using passive sorbent tubes, were adapted to production pads in this study and include eight additional speciated VOCs. Sample collection began in fall 2013 and continued through summer 2014, which consisted of 14-day sorbent tube exposures at multiple locations around each production pad. Rural production pad measurements will also be compared to urban-scale 14-day passive measurements collected in Downtown Denver as part of this evaluation. Seasonal impacts on VOC concentrations as well as sorbent tube performance from a number of duplicate samples and blanks that were deployed alongside primary samples will be assessed. Specifics of each active production pad such as number of wells, number of tanks, and annual production rate will also be presented in poster format during the June 2015 AWMA Annual Conference.

Ocean and Coastal Acidification off New England and Nova Scotia

New England coastal and adjacent Nova Scotia shelf waters have a reduced buffering capacity because of significant freshwater input, making the region’s waters potentially more vulnerable to coastal acidification. Nutrient loading and heavy precipitation events further acidify the region’s poorly buffered coastal waters. Despite the apparent vulnerability of these waters, and fisheries’ and mariculture’s significant dependence on calcifying species, the community lacks the ability to confidently predict how the region’s ecosystems will respond to continued ocean and coastal acidification. Here, we discuss ocean and coastal acidification processes specific to New England coastal and Nova Scotia shelf waters and review current understanding of the biological consequences most relevant to the region. We also identify key research and monitoring needs to be addressed and highlight existing capacities that should be leveraged to advance a regional understanding of ocean andcoastal acidification.

Investigation of Low Cost Sensor-Based Leak Detection System for Fence Line Applications

With recent technological advances, low-cost time-resolved sensors may become effective tools to support time-integrated passive sampling strategies by helping to decipher origin of emissions in real-time. As part of the Petroleum Refinery Risk and Technology Review, New Source Performance Standards rule, the US EPA is proposing use of two-week passive sorbent tube fence line monitoring for benzene. A prototype low-cost sensor-based, stand-alone air measurement (SAM) network, called SEnsor NeTwork INtelligent Emission Locator (SENTINEL), was developed by EPA’s Office of Research and Development and deployed near a refinery in South Philadelphia. The sensor network consists of a base station and one solar-powered remote station, measuring non-speciated air pollutant concentrations using passive photoionization detectors (PIDs), with sensors for temperature, pressure, and humidity and a 3-D sonic anemometer for wind field diagnostics. Logged at one second intervals, data from the remote station is transferred over a short range network to the base station where it can be accessed remotely via cellular modem. In addition to system design and current sensor performance characteristics, time-series analysis providing insights into source identification under different meteorological conditions will be presented. The limitations of the current design and recommendations for future improvements will also be discussed.
