Ecosystems in the tropical coastal zone exchange particulate organic matter (POM) with adjacent systems, but differences in this function among ecosystems remain poorly quantified. Seagrass beds are often a relatively small section of this coastal zone, but have a potentially much larger ecological influence than suggested by their surface area. Using stable isotopes as tracers of oceanic, terr...

There was a net influx of suspended particulate matter to the uppermost part of the Rhode River estuary during the several years of this study. Most of the influx was due to episodic discharges of suspended sediment from the watershed during heavy rains. In contrast, tidal exchange of particulate matter was not related to rainstorms. Sediment composition data and historical records indicate tha...

Background Air quality monitoring in brick kilns indicates very high concentrations of airborne particulate matter. Air pollution from brick kilns poses an enhanced threat to the environment and to human health. Objective To evaluate airborne particulate matter concentration and health status of brick kiln workers. Method A cross-sectional comparative study was conducted in the Kathmandu valley...

BACKGROUND We report on a novel approach to the analysis of suspended particulate data in a rural setting in southern Ontario. Analyses of suspended particulate matter and associated air quality standards have conventionally focussed on 24-hour mean levels of total suspended particulates (TSP) and particulate matter <10 microns, <2.5 microns and <1 micron in diameter (PM10, PM2.5, PM1, respecti...

Background & Aims of the Study: According to statistics reported by the international organization, 500,000 people annually due to airborne particulate matter exposure of the air are dying prematurely. Studies show the dust storm is responsible for the 7.1 % increase of fatality. Control of particulate matter is one of the most important methods of direct and indirect effects of par...

The yields of the tropical rivers of Southeast Asia supply large quantities of carbon to the ocean. The origin and dynamics of particulate organic matter were studied in the Houay Xon River catchment located in northern Laos during the first erosive flood of the rainy season in May 2012. This cultivated catchment is equipped with three successive gauging stations draining areas ranging between ...

Patos Lagoon is the largest choked coastal lagoon in world (250 km long, 40 wide and mean depth of 5 m), with banks formed by sand predominantly muddy bottom. The circulation mainly driven wind river flow, a minor contribution local microtidal regime. This one most studied water bodies Brazil. suspended particulate matter (SPM) data compendium consists over four decades (1978–2019) SPM gathered...

The circulation and transport of suspended particulate matter in the Caravelas Estuary are assessed. Nearlysynoptic hourly hydrographic, current (ADCP velocity and volume transport) and suspended particulate matter data were collected during a full semidiurnal spring tide, on the two transects Boca do Tomba and Barra Velha and on longitudinal sections at low and high tide. On the first transect...
