Aerobic scope, the difference between standard metabolic requirements and maximum metabolic capacity, is considered a particularly important metric influencing ecological success in fishes. Crude oil exposure can impair cardiorespiratory function in fishes, which reduces maximum metabolic rate, aerobic scope, and may impair ecological performance. Oil exposure is not the only environmental stressor that can affect aerobic scope, especially in areas affected by crude oil spills. Hypoxia (low dissolved oxygen) is also known to constrain maximum metabolic rate, yet there has been little effort to explore how hypoxia may influence the magnitude of metabolic injury following oil exposure. Therefore, our goal was to investigate the effects of acute oil exposure and hypoxia on the metabolic performance of red drum (Sciaenops ocellatus), an economically important fish common in the Gulf of Mexico. Here, sub-adult red drum were exposed to crude oil for 24 h before being exposed to hypoxic conditions following exhaustive exercise. Our results show that hypoxia exposure combined with crude oil exposure results in significantly reduced aerobic scope, which was additive compared to the reductions caused by each stressor alone. We also quantified hypoxia tolerance among treatments following exposure, and our results showed no changes to hypoxia tolerance among individuals, regardless of exposure to hypoxia or oil. These data offer insight into the metabolic constraints facing fishes exposed to oil while concurrently subjected to hypoxia, a notable climate change stressor.Worldwide, water resources are increasingly under pressure. The Water accounting approach of the System of Environmental-Economic Accounting (SEEA) has been developed to inform decision-makers on water supply, use, and quality. However, a critical issue in water accounting is finding data and models to populate SEEA water accounts. In particular, there are challenges in aligning hydrological models with accounting principles. Also, there is a need to test further how the SEEA water accounts can be connected to policy uses. The objective of this study is to develop water accounts with the use of a hydrological model. Specifically, we apply the SWAT hydrological model in the Buyuk Menderes Basin in Turkey to estimate the key hydrological parameters required for water accounting. To adapt and link SWAT to SEEA water accounts, we develop supply and use tables and asset accounts following the SEEA water for the year 2014 and explore how water accounts can inform policymaking. This article provides new insights into the added value of using a hydrological model in constructing water accounts for better water resources management.As natural gas has grown in importance as a global energy source, leakage of methane (CH4) from wells has sometimes been noted. Leakage of this greenhouse gas is important because it affects groundwater quality and, when emitted to the atmosphere, climate. Nesuparib We hypothesized that streams might be most contaminated by CH4 in the northern Appalachian Basin in regions with the longest history of hydrocarbon extraction activities. To test this, we searched for CH4-contaminated streams in the basin. Methane concentrations ([CH4]) for 529 stream sites are reported in New York, West Virginia and (mostly) Pennsylvania. Despite targeting contaminated areas, the median [CH4], 1.1 μg/L, was lower than a recently identified threshold indicating potential contamination, 4.0 μg/L. [CH4] values were higher in a few streams because they receive high-[CH4] groundwaters, often from upwelling seeps. By analogy to the more commonly observed type of groundwater seep known as abandoned mine drainage (AMD), we introduce the term, "gas leak discharge" (GLD) for these waters where they are not associated with coal mines. GLD and AMD, observed in all parts of the study area, are both CH4-rich. Surprisingly, the region of oldest and most productive oil/gas development did not show the highest median for stream [CH4]. Instead, the median was statistically highest where dense coal mining was accompanied by conventional and unconventional oil and gas development, emphasizing the importance of CH4 contamination from coal mines into streams.
Fine particulate matter (PM
) air pollution has been associated with increased risks of acute myocardial infarction (AMI), but it remains unknown about the potentially differentiated effects of size-fractionated particulate matter on AMI risk.

To identify the specific size ranges that dominate the effects of particulate matter on AMI onset.

We conducted a time-series study in Shanghai, China from January 2014 to December 2018. We evaluated particle size distribution of 0.01μm to 2.5μm from an environmental supersite and AMI emergency hospitalizations from the largest cardiovascular hospital in Shanghai. We used over-dispersed generalized additive models to estimate the associations of size-fractionated particle number concentrations (PNC) with AMI and its types.

We identified a total of 4720 AMI emergency hospitalizations. PM
was significantly associated with increased AMI risk on the concurrent day. The associations were significant only for PNC<0.3μm. For an IQR increase of PNCs for size ranges 0.01-0.03μm, 0.03-0.05μm, 0.05-0.10μm and 0.10-0.30μm, AMI hospitalizations increased by 6.68% (95% CI 2.77%, 10.74%), 6.53% (95% CI 2.08%, 11.17%), 5.78% (95% CI 0.92%, 10.88%) and 5.92% (95% CI 1.31%, 10.74%), respectively. The associations of PNC<0.05μm remained significant when adjusting for other air pollutants. There were consistently much stronger associations of particles with ST-segment elevation AMI than those with non-ST-segment elevation AMI.

This epidemiological investigation suggested that ultrafine particles, especially those <0.05μm, may be mainly responsible for the acute AMI risk induced by PM
.
This epidemiological investigation suggested that ultrafine particles, especially those less then 0.05 μm, may be mainly responsible for the acute AMI risk induced by PM2.5.
Although some studies have suggested that exposure to polycyclic aromatic hydrocarbons (PAHs) induces neurodevelopmental disturbances in children and neurodegeneration in animals, the neurotoxic effect of PAH exposure is unclear in adults. The aim was to examine the associations of PAH exposure with brain structure and neuropsychological function in adults without known neurological diseases.

This study included 421 men and 528 women dwelling in four cities in the Republic of Korea. Urinary concentrations of four PAH metabolites (1-hydroxypyrene, 2-naphthol, 1-hydroxyphenanthrene, and 2-hydroxyfluorene) were obtained. Participants underwent brain 3T magnetic resonance imaging and neuropsychological tests. Cortical thickness and volume were estimated using the region-of-interest method. Separate generalized linear models were constructed for each sex, adjusting for age, years of education, cohabitation status, income, tobacco use, alcohol consumption, and vascular risk factors.

The mean (standard deviation) age was 68.
