Abstract:
It is widely claimed that at least 80% of the plastic litter entering marine environments comes from land-based sources, yet there is little empirical evidence to support this. Most studies to date predict the flux of litter from land to sea using global models based on a handful of field studies conducted mostly in developed, Northern Hemisphere countries; others use proxies such as per capita waste generation and proportion of mismanaged waste to predict litter loads entering the sea. It thus remains unclear how accurate these predictions are, particularly for African countries where few fie

The conversion of land to agricultural, mining, industrial, or residential uses significantly alters the hydrological characteristics of the land surface and modifies pathways and rates of water flow. If this occurs over large or critical areas of a catchment, it can have significant short and long-term impacts, on the quality of water. While there are methods availa

This paper examines the Non-Point Source Identification Strategy (NPSIS); a modification of the Land Use Conflict Identification Strategy (LUCIS): NPSIS is a raster model useful for identifying non-point sources of water pollution from three known contributors (agriculture, domestic, and natural background). By using a standard operating procedure, developers are able to create standardized datasets useful for identifying non-point sources of water pollution throughout the contiguous United States. The NPSIS model process requires the use of three “non-point source water pollution” contributor

Still, one of these sources play a more crucial role in the protection of the marine environment than the other since that source is estimated to stand for 80 percent of all the marine pollution; namely marine pollution from land-based sources.

Abstract:
Microplastic are plastics that are < 5mm and is a contaminant of emerging concern in the aquatic environment. They are produced to be of a microscopic size or are created through the fragmentation of larger plastic material due to degradation. Microplastic has been found to be ubiquitous in the marine and freshwater environment with shoreline and deep sea sediment, oceans, rivers and lakes throughout the world observed to be polluted by microplastic. Wild populations of aquatic biota with various feeding behaviour have been observed to ingest microplastic. Exposure studies have also demonstrat

Abstract:
Dallas is the third largest growing industrialized city in the state of Texas. the prevailing air quality here is highly influenced by the industrialization and particulate matter 2.5µm (PM2.5) has been found to be one of the main pollutants in this region. Exposure to PM2.5 in elevated levels could cause respiratory problems and other health issues, some of which could be fatal. the current study dealt with the quantification and analysis of the sources of emission of PM2.5 and an emission inventory for PM2.5 was assessed. 24-hour average samples of PM2.5 were collected at two monitoring site

Abstract:
Sources of E. coli were determined from impaired waterways in the Appomattox River watershed (in the lower Piedmont and South-Central Virginia) for the development of bacterial Total Maximum Daily Loads (TMDLs). The Appomattox River watershed is primarily undeveloped with 70.8% of the land forested, 17.0% used for agriculture (mainly livestock production), and 7.7% classified as water, wetland or barren land. The remaining 4.5% is developed for residential, commercial, and industrial land uses (mainly within the city of Petersburg). Using Antibiotic Resistance Analysis, a known source libra

Abstract:
Ce travail porte sur quelques questions posées par l'identification de sources de pollution d'eaux de surface. Les questions traitées sont relatives à l'identification de paramètres pour différents modèles, à l'identifiabilité, à la stabilité du problème inverse et à des méthodes numériques de résolution de ces problèmes inverses. Les modèles considérés portent sur la concentration de la demande biologique en oxygène (DBO) et sur le déficit en oxygène (DO) couplé avec la DBO. Nous avons obtenu, dans un premier temps, des résultats d'identifiabilité, de stabilité et une méthode explicite d'iden

Abstract:
Background Air quality in Africa has remained a relatively under-researched field. Most of the African population is dependent on biomass for cooking and heating, with most of the combustion happening in low efficiency stoves in unvented kitchens. The resulting high emissions are compounded by ingress from poor outdoor air in a context of poor emissions controls. The situation is dire in slum households where homes are crowded and space is limited, pushing households to cook in the same room that is used for sleeping. This study assessed the levels of particulate matter with aerodynamic diamet
