The suspended particulate material (SPM) present in waters has fundamental importance for a better understanding of environmental behaviors aquatic pollutants. This work determined the physicochemical parameters (pH, temperature, conductivity, total organic carbon and metals concentration) water samples from Mundau-Manguaba estuarine-lagoon system, Alagoas, Brazil. extracted characterized matte...

In the manuscript by Wang et al., the authors claim that they have characterized the archaeal tetraether membrane lipids (GDGTs) produced by the marine euryarchaeota group II (MGII) and assess the effect of their synthesized lipids on the GDGT-based paleotemperature proxy TEX86. For that purposes, they analyzed core lipids (CL) and intact polar lipids (IPL) GDGTs, they performed 454 pyrosequenc...

Comprehensive studies on polycyclic aromatic hydrocarbons (PAHs) within an urban river are urgently needed to carry out strategies to limit their contamination and dispersal. Here, we analyzed 16 PAH occurrences in water, suspended particulate matter (SPM), and sediment monthly for a year in the Maozhou River mainstream (Shenzhen, South China). Monthly rainfall positively correlated with both t...

[1] Nearly continuous data collected using novel methods are utilized to advance the understanding of turbulence and suspended particulate matter (SPM) dynamics under strong tidal flow conditions. Key instrumentation includes a single acoustic current profiler that provides nearly continuous, concurrent turbulence and SPM information with respect to depth near the seafloor and within the water ...

Analytical methods for determining 14 endocrine-disrupting compounds (EDCs) in coastal waters, suspended particles, and sediment samples were successfully performed by ultrafast liquid chromatography with photodiode array fluorescence detections (UFLC-PDA-FLD). Solid‑phase extraction (SPE) ultrasound-assisted (USE) used sample preparation. Two chromatographic have been developed. An isocratic s...

Suspended particulate matter (SPM) strongly alters the trophic environment of photosymbiotic aquatic organisms. At high particles loads, phototrophic energy gains can be diminished due to light absorption by suspended particles, and stress from particle abrasion or deposition on tissues. However, energy gains are enhanced if organisms are able to use SPM as a food source. For photosymbiotic ben...

No observed data have been found in the Fukushima Prefecture (FP) for the time-series of atmospheric radionuclides concentrations just after the Fukushima Daiichi Nuclear Power Plant (FD1NPP) accident. Accordingly, current estimates of internal radiation doses from inhalation, and atmospheric radionuclide concentrations by atmospheric transport models are highly uncertain. Here, we present a ne...

Variation in water quality can directly affect the composition of benthic assemblages on coral reefs. Yet, few studies have quantified nutrient and suspended particulate matter (SPM) to examine their potential impacts community structure, especially around high oceanic islands. We assessed spatio-temporal variation nutrients SPM across six sites American Samoa over a 12-month period used explor...

Field observations were carried out in the East China Sea (ECS) in October 2000, May 2001 and April–May 2002. Biogenic silica (BSi) in core sediments, sediment traps, and suspended particulate matter (SPM) was measured; silicate profiles in pore waters were examined. The concentration of BSi in SPM was high in coastal areas. The content of BSi in ECS sediments is less than 1%, as the result of ...

Many estuaries exhibit seasonality in the estuary-scale distribution of suspended particulate matter (SPM). This SPM depends on various factors, including freshwater discharge, salinity intrusion, erodibility, and ability cohesive to flocculate into larger aggregates. Various authors indicate that biotic such as presence algae their excretion sticky transparent exopolymer particles (TEP), affec...
