Environmental effects of stratospheric ozone depletion, UV radiation, and interactions with climate change: UNEP Environmental Effects Assessment Panel, Update 2020
(JOURNAL) [Published : Jan 20, 2021]
Changes in solar UV radiation and climate have direct and indirect effects on the way in which cycling of elements (e.g., carbon, nitrogen and sulfur cycles) and the fate of contaminants occur in aquatic and terrestrial ecosystems. It is well established that a wide range of synt...
Surveillance for harmful algal bloom events and associated human and animal illnesses—One Health Harmful Algal Bloom System, United States, 2016—2018
(JOURNAL) [Published : Dec 18, 2020]
Harmful algal bloom (HAB) events can result from the rapid growth, or bloom, of photosynthesizing organisms in natural waterbodies. HAB events can be exacerbated by nutrient pollution and a warming climate (1) and can negatively impact the health of humans, animals, and the envir...
Diets Enriched with Coconut, Fish, and Olive Oil Modify Peripheral Metabolic Effects of Ozone in Rats
(JOURNAL) [Published : Jan 01, 2021]
Dietary factors may modulate metabolic effects of air pollutant exposures. We hypothesized that diets enriched with coconut oil (CO), fish oil (FO), or olive oil (OO) would alter ozone-induced metabolic responses. Male Wistar-Kyoto rats (1-month-old) were fed normal diet (ND), or...
The impact of air pollution on terrestrial managed and natural vegetation.
(JOURNAL) [Published : Oct 30, 2020]
There is a long history of awareness of air pollution impacts on vegetation but until the twentieth century this was largely based on field observations of injury to vegetation in the absence of measurements of the pollutants. In the UK following the industrial revolution urban a...
Factors influencing carbon stocks and accumulation rates in eelgrass meadows across New England, USA
(JOURNAL) [Published : Dec 01, 2020]
Increasing the protection of coastal vegetated ecosystems has been suggested as one strategy to compensate for increasing carbon dioxide (CO2) in the atmosphere as the capacity of these habitats to sequester and store carbon exceeds that of terrestrial habitats. Seagrasses are a ...
Offspring Susceptibility to Metabolic Alterations Due to Maternal High-Fat Diet and the Impact of Inhaled Ozone Used as a Stressor
(JOURNAL) [Published : Oct 01, 2020]
The influence of maternal high-fat diet (HFD) on metabolic response to ozone was examined in Long-Evans rat offspring. F0 females were fed control diet (CD; 10%kcal from fat) or HFD (60%kcal from fat) starting at post-natal day (PND) 30. Rats were bred on PND 72. Dietary regimen ...
Mutagenicity- and Pollutant-Emission Factors of Pellet-Fueled Gasifier Cookstoves: Comparison with Other Combustion Sources
(JOURNAL) [Published : Oct 15, 2020]
Emissions from solid-fuel burning cookstoves are associated with 3 to 4 million premature deaths annually and contribute significantly to climate-forcing. Pellet-fueled gasifier stoves have some emission factors (EFs) approaching those of gas-fuel stoves; however, their emissions...
Assessment of NO2 Observations during DISCOVER-AQ and KORUS-AQ Field Campaigns
(JOURNAL) [Published : May 19, 2020]
NASA’s Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality (DISCOVER-AQ, conducted in 2011–2014) campaign in the United States and the joint NASA and National Institute of Environmental Research (NIER) Korea–United S...
A Community EcoHealth Index from EnviroAtlas Ecosystem Services Metrics
(JOURNAL) [Published : Aug 02, 2019]
Human health is inextricably tied to ecosystem services (ES), including those associated with greenspace in urban communities. EnviroAtlas provides close to 100 maps of ES metrics based on high-resolution land cover data in featured communities across the contiguous United States...
Sediment retention by natural landscapes in the conterminous United States
(JOURNAL) [Published : Nov 01, 2020]
Soil functions provide vital ecosystem services, from sequestering carbon to providing food and moderating floods. Soil erosion threatens the provisioning of these services while deteriorating downstream water quality. Vegetation plays an important role in soil retention – by hol...
Using satellite-based measurements to explore spatiotemporal scales and variability of drivers of new particle formation
(JOURNAL) [Published : Oct 27, 2016]
New particle formation (NPF) can potentially alter regional climate by increasing aerosol particle (hereafter particle) number concentrations and ultimately cloud condensation nuclei. The large scales on which NPF is manifest indicate potential to use satellite-based (inherently ...
Influence of infrastructure on water quality and greenhouse gasdynamics in urban streams
(JOURNAL) [Published : Jun 13, 2017]
Streams and rivers are significant sources of nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4), and watershed management can alter greenhouse gas emissions from streams. GHG emissions from streams in agricultural watersheds have been investigated in numerous studies,...
Universal industrial sectors integrated solutions modulefor the pulp and paper industry
(JOURNAL) [Published : Sep 01, 2017]
The U.S. is the world’s second-leading producer of pulp and paper products after China. While the pulp and paper industry has reduced its environmental impacts, concerns remain regarding the emissions of oxides of nitrogen (NOX) and sulfur dioxide (SO2) from the sector. Boilers, ...
A Review of Water Quality Responses to Air Temperature and Precipitation Changes 2: Nutrients, Algal Blooms, Sediment, Pathogens
(JOURNAL) [Published : Dec 20, 2018]
In this paper we review the published, scientific literature addressing the response of nutrients, sediment, pathogens, and cyanobacterial blooms to historical and potential future changes in air temperature and precipitation. The goal is to document how different attributes of w...
Isoprene Emission Response to Drought and the Impact on Global Atmospheric Chemistry
(JOURNAL) [Published : Jul 01, 2018]
Biogenic isoprene emissions play a very important role in atmospheric chemistry. They are strongly dependent on various environmental conditions, such as temperature, solar radiation, plant water stress, ambient ozone and CO2 concentrations, and soil moisture. Current biogenic ...
Earth Observation-Based Ecosystem Services Indicators for National and Subnational Reporting of the Sustainable Development Goals
(JOURNAL) [Published : Jul 01, 2020]
Decision-making impacting sustainability occurs at national and subnational levels, highlighting the need for Earth observations (EO) and geospatial data for assessing Sustainable Development Goals (SDG) at multiple spatial extents and scales. EnviroAtlas, developed by the U.S. E...
Seasonal disconnect between streamflow and retention shapes riverine nitrogen export in the Willamette River Basin, Oregon
(JOURNAL) [Published : Jan 01, 2020]
Watershed nutrient balance studies traditionally focus on annual fluxes. In areas with strongly seasonal, Mediterranean-type climate regimes, riverine nutrient export may be greater during wet seasons when hydrologic forcing overwhelms or bypasses retention mechanisms. By combini...
A framework for nitrogen futures in the shared socioeconomic pathways
(JOURNAL) [Published : Mar 01, 2020]
Humanity’s transformation of the nitrogen cycle has major consequences for ecosystems, climate and human health, making it one of the key environmental issues of our time. Understanding how trends could evolve over the course of the 21st century is crucial for scientists an...
Unexpected Nitrogen Sources in a Tropical Urban Estuary
(JOURNAL) [Published : Mar 21, 2020]
Tropical urban estuaries are severely understudied. Little is known about the basic biogeochemical cycles and dominant ecosystem processes in these waterbodies, which are often low lying and heavily modified. The San Juan Bay Estuary (SJBE) in San Juan, Puerto Rico, is an example...
Positive correlation between wood δ 15N and stream nitrate concentrations in two temperate deciduous forests
(JOURNAL) [Published : Feb 27, 2020]
A limitation to understanding drivers of long-term trends in terrestrial nitrogen (N) availability in forests and its subsequent influence on stream nitrate export is a general lack of integrated analyses using long-term data on terrestrial and aquatic N cycling at comparable spa...
