The Caloosahatchee Estuary in southwest Florida, USA, is regularly subject to the introduction of toxic Microcystis aeruginosa blooms, often originating from eutrophic Lake Okeechobee via C-43 Canal. focus this study was determine responses one these introduced blooms progressively elevated salinity levels as bloom water mass moved through estuary. In upper estuary, salinities were freshwater, and surface large colonies M. observed, along with peak microcystin toxin concentrations up 107 μg L-1, all particulate fraction. mid-estuary, increased 2-6, again 259 however, significant extracellular also observed (i.e., 17.8 L-1), suggesting a level osmotic stress on aeruginosa. lower ranged 6 25 very few viable but 0.5 L-1) present throughout column.

Coastal eutrophication caused by anthropogenic nutrient inputs is one of the greatest threats to health coastal estuarine and marine ecosystems worldwide. To better understand manage this threat, we compared six contrasting that are subjected a range riverine freshwater (buoyancy) nutrients address (i) impacts on ecosystem services; (ii) how traits minimize or amplify these impacts; (iii) synergies among pressures (nutrient enrichment, over fishing, development, climate-driven in particular); (iv) management ecosystems. Globally, ~ 24% N released watersheds estimated reach Our comparative assessment revealed terms spatial extent habitat degradation, Chesapeake Bay ranks number followed rank order northern Gulf Mexico, Baltic Sea, Great Barrier Reef, East China Sea Adriatic Sea; increases loading are, will continue be, exacerbated with other including development sea surface temperature, acidification rainfall; when defined quantitative ranges primary production, trophic status not useful for relating impacts.

Abstract This assessment by the Environmental Effects Assessment Panel (EEAP) of United Nations Environment Programme (UNEP) provides latest scientific update since our most recent comprehensive (Photochemical and Photobiological Sciences, 2019, 18, 595–828). The interactive effects between stratospheric ozone layer, solar ultraviolet (UV) radiation, climate change are presented within framework Montreal Protocol Sustainable Development Goals. We address how these global environmental changes affect atmosphere air quality; human health; terrestrial aquatic ecosystems; biogeochemical cycles; materials used in outdoor construction, energy technologies, fabrics. In many cases, there is a growing influence from seasonality extreme events due to change. Additionally, we assess transmission severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which responsible for COVID-19 pandemic, context linkages with UV radiation Protocol.

Populations and metropolitan centers are accumulated in coastal areas around the world. In view of fact that they geographically adjacent to coasts intense anthropogenic activities, increasing global offshore pollution has been an important worldwide concern over past several decades become a very serious problem needs be addressed urgently. Due pollution, various geological disasters occur high frequency, including intensified erosion salinization soils, frequent collapses landslides seismic activities. Moreover, shows increasingly impacts on topography geomorphology areas, degradation, retreating coastlines estuary delta erosion. Offshore sedimentation processes strongly influenced by pH changes terrestrial discharges, sedimentary dynamics have extremely acute complex due pollution. The seabed hydrodynamic environment determine fate transport pollutants entering regions. Coastal estuaries, port basins lagoons relatively moderate ocean currents winds more likely accumulate pollutants. regions undersea canyons can used as conduits for transporting from continent seabed. It is particularly noteworthy spatial/temporal distribution species, community structures, ecological functions undergone unprecedented recent decades. stable succession development trend marine ecosystems broken. thus identify regulate quantity, composition transportation their behavior ecosystems. particular, crucial actions stabilizing ecosystems, species biodiversity, should implemented enhance anti-interference capabilities. This review provides overview current situation well major trends pollutant transformation sediments, bioaccumulation diffusion. study retrospectively reviews long-term evolution perspective geology, analyses potential risks associated with released research influence based geology undoubtedly needed.
