GESAMP - Reports and Studies, 97. The magnitude and impacts of anthropogenic atmospheric nitrogen inputs to the ocean
World Meteorological Organization (WMO) ; Food and Agriculture Organization (FAO); United Nations Educational, Scientific and Cultural Organization (UNESCO); et al. - WMO, 2018The present global modelling study of the Nr atmospheric cycle and Nr deposition to the ocean is the first that evaluates past, present and future Nr atmospheric deposition accounting for ON primary sources as well as for secondary ON chemical formation as a N-dependent process. While the total Nr deposition to the ocean is not expected to change significantly by 2050, the relative importance of oxidized and reduced N is expected to change, with an increasing proportion of ammonium compared to nitrate, resulting from more efficient controls on terrestrial emissions of nitrogen oxides (NOx) com ...
European waters - assessment of status and pressures
European Environment Agency (EEA) - EEA, 2012This report's results present good and robust European overviews of the data reported by the first RBMPs, and of the ecological status and pressures affecting Europe's waters. Europe's waters are affected by several pressures, including water pollution, water scarcity and floods. Major modifications to water bodies also affect morphology and water flow. To maintain and improve the essential functions of our water ecosystems, we need to manage them well.

The World’s Worst Pollution Problems : Assessing Health Risks at Hazardous Waste Sites
The World’s Worst Pollution Problems: Assessing Health Risks at Hazardous Waste Sites report reveals that close to 125 million people are at risk from toxic pollution across 49 low to middle-income countries. Also, the report, for the first time estimates the total global burden of disease attributed to toxic pollution from industrial sites in these countries. It establishes the global burden of disease from toxic pollution as on par with better-known public health problems such as malaria and tuberculosis.

L'accumulation inquiétante des polluants dans l'Arctique: In lemonde.fr
2012S'il est vrai, comme le pense l'ex-première ministre norvégienne Gro Harlem Brundtland, que "les régions polaires demeurent celles du monde sur lesquelles on a le moins de connaissances", les travaux présentés du 22 au 27 avril à Montréal, lors de la conférence de l'Année polaire internationale 2012, ont permis de mesurer les avancées scientifiques réalisées.
C'est particulièrement le cas pour les études concernant la présence en Arctique de métaux - comme le mercure - et de polluants organiques persistants (POP), dont les impacts sur la santé et l'environnement sont très nocif ...

Pseudo steady states of HONO measured in the nocturnal marine boundary layer: a conceptual model for HONO formation on aqueous surfaces
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 7. Wojtal P.; Halla J.D.; McLaren R. - Copernicus GmbH, 2011A complete understanding of the formation mechanism of nitrous acid (HONO) in the ambient atmosphere is complicated by a lack of understanding of processes occurring when aqueous water is present. We report nocturnal measurements of HONO, SO2 and NO2 by differential optical absorption spectroscopy over the ocean surface in a polluted marine environment. In this aqueous environment, we observed reproducible pseudo steady states (PSS) of HONO every night, that are fully formed shortly after sunset, much faster than seen in urban environments. During the PSS period, HONO is constant with time, in ...

Size dependence of volume and surface nucleation rates for homogeneous freezing of supercooled water droplets
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 3. Kuhn T.; Earle M.E.; Khalizov A.F.; et al. - Copernicus GmbH, 2011The relative roles of volume and surface nucleation were investigated for the homogeneous freezing of pure water droplets. Experiments were carried out in a cryogenic laminar aerosol flow tube using supercooled water aerosols with maximum volume densities at radii between 1 and 3 μm. Temperature- and size-dependent values of volume- and surface-based homogeneous nucleation rates between 234.8 and 236.2 K were derived using a microphysical model and aerosol phase compositions and size distributions determined from infrared extinction measurements in the flow tube. The results show that the cont ...

A blueprint for ocean and coastal sustainability : an inter-agency paper towards the preparation of the UN Conference on Sustainable Development (Rio+20)
UNESCO, 2011The Blueprint provides an overview of the threats faced by the oceans, including unsustainable use, deforestation of mangroves, disappearance of coral reefs, ocean acidification and climate change. It further highlights the role of oceans in regulating the climate, contributing to food security and sustaining livelihoods.
15th Biennial Report on Great Lakes Water Quality
The focus of this report is the nearshore zone, the vital ecological link between watersheds, tributaries, wetlands, groundwater, and offshore waters of the Great Lakes. Most people live in the nearshore and get their drinking water from this zone. The nearshore also supports critical habitat for fish, invertebrate and wildlife populations. Beach losings, nuisance algal growth, the establishment of alien invasive species, and habitat loss are just some of the troublesome developments in the nearshore that act as harbingers of future changes in offshore waters. A revised Agreement should be ...
