Suspended Particulate Matter (SPM) plays an important role in controlling water quality, particularly turbid estuaries. SPM may be impacted by changes weather and climate, including potential the frequency or intensity of extremes. Yet, linkages between extreme events wind river discharge, these have on local dynamics spatial patterns estuarine are, to date, largely unknown. This study investig...

Total metal concentrations are usually used as geochemical tracers to identify sources of suspended particulate matter (SPM) and sediment deposits, but their non-conservative behaviour can lead large uncertainties. This non-conservatism may be a significant issue when total contemporary SPM determine historical sources, diagenesis processes and/or past anthropogenic inputs modify in core profil...

Artificial sweeteners (ASs), as a new emerging pollutant, the fate from wastewater treatment plants (WWTPs) to sea is growing concerned. In this study, distribution and polluted loading of six typical ASs were analyzed based on measurement in influent, primary effluent, secondary tertiary suspended particulate matter (SPM), sludge four WWTPs receiving waters near coast Shenzhen city, China. Ele...

Indoor environment air pollution measurement has become a necessity because of global warming and climate change. All across the globe researchers are trying to monitor the pollutant gases precisely in real time. Sensing system using sensor arrays has been developed to monitor indoor environment, however, these systems are costly and have not gained wide acceptance. Precise measurement of indoo...

Ocean color satellite sensors are powerful tools to study and monitor the dynamics of suspended particulate matter (SPM) discharged by rivers in coastal waters. In this study, we test the capabilities of Landsat-8/Operational Land Imager (OLI), AQUA&TERRA/Moderate Resolution Imaging Spectroradiometer (MODIS) and MSG-3/Spinning Enhanced Visible and Infrared Imager (SEVIRI) sensors in terms of sp...

The uptake and release of 109Cd, 51Cr, 60Co, 59Fe, 54Mn, and 65Zn were studied using end-member waters and particles from Port Jackson estuary, Australia. The kinetics of adsorption and desorption were studied as a function of suspended particulate matter (SPM) loading and salinity. Batch experiments showed that the position and slope of the pH edges are dependent on the metal and on the salini...

The estimation of the carrying capacity (CC) is a fundamental process in integrated environmental management, policy making, and decision making. Aquaculture has been studied since 1960s to allow production limits aquaculture projects and, hence, their maximum economic performance within sustainable for local environment. One major drawback these approaches that they can provide CC estimates af...

Two oceanographic cruises were completed in September 2016 and August 2017 to investigate the distribution of particulate organic matter (POM) across northeast Chukchi Shelf. Both periods characterized by highly stratified conditions, with major contrasts regional water masses that impacted POM distributions. Overall, surface waters low chlorophyll fluorescence (Chl Fl < 0.8 mg m−3) particle be...

The objective of this paper was to compare the limits three image-based atmospheric correction models (top atmosphere (ToA), dark object subtraction (DOS), and cosine sun zenith angle (COST)), physical (atmospheric for flat terrain (ATCOR), fast line-of-sight analysis spectral hypercubes (FLAASH)), ACOLITE) retrieving suspended particulate matter (SPM) concentrations in inland water bodies usin...
