An integrated approach for the assessment of land-based pollution loads in the coastal zone

Modelagem da drenagem urbana e avaliação das cargas bacteriológicas na Vertente Marítima de Fortaleza, Ceará

“…A água, como solvente universal e veículo das diversas substâncias, pode ser um indicador das condições ambientais das bacias hidrográficas (BRITES & GASTALDINI, 2007;ZAFFANI, 2012), e os sistemas de drenagem podem representar fontes pontuais de poluição aos corpos receptores aos quais se destinam, como lagos, rios ou oceanos (PEREIRA et al, 2015;TOSIC et al, 2017;BATISTA & HARARI, 2017).…”

Hydrodynamic modelling of a polluted tropical bay: Assessment of anthropogenic impacts on freshwater runoff and estuarine water renewal

“…One such water body is Cartagena Bay (Fig. 1), Colombia, where human development has led to the eradication of coral reefs and seagrass communities (Díaz and Gómez, 2003;Restrepo et al, 2006;Restrepo, 2008) and continues to cause multifactorial pollution impacts, including hypoxic conditions and drastic reductions in artisanal fisheries (Tosic et al, 2019(Tosic et al, , 2018.…”

“…Various problems related to the waters, sediments and biota of Cartagena Bay have been observed for decades, including excessive turbidity, eutrophication, hypoxia, fecal contamination, presence of heavy metals, hydrocarbons and pesticides (FAO & CCO, 1978;Garay, 1983: Guerrero et al, 1995Castro, 1997;Garay and Giraldo, 1997;Alonso et al, 2000;Parga-Lozano et al, 2002;Tuchkovenko and Lonin, 2003;Restrepo et al, 2006Restrepo et al, , 2016Cañon Páez et al, 2007;Johnson-Restrepo et al, 2008;Olivero-Verbel et al, 2008, 2009Cogua et al, 2012;Mogollón, 2013;Jaramillo-Colorado et al, 2015Tosic et al, 2019). While the bay's water quality issues have been linked to local domestic and industrial wastewater, as well as continental sources of pollution (Tosic et al, 2018), foremost to these sources is runoff from the Dique Canal flowing from the Magdalena River, which is the principal source of fluvial fluxes discharging in the Caribbean Sea (Restrepo and Kjerfve, 2000;Restrepo, 2008).…”

“…If these local sources of pollution were to persist, reductions in freshwater discharge would simply result in greater algal blooms and further oxygen depletion, as the lack of turbid freshwater plumes would increase residence time and improve transparency, allowing primary productivity to flourish with the continued contribution of nutrients from local wastewater (Lonin, 1997a;Tuchkovenko et al, 2000). Yet unfortunately, the city's plan to redirect local wastewater sources out of the bay has fallen behind schedule and significant domestic and industrial pollution loads continue to discharge into the bay (Tosic et al, 2018).…”

Exceedance probability assessment of bathing water quality standards in lake Van based on a geostatistical analysis

“…Numerous research studies have been conducted so far to understand the causes of coastal pollution around the recreational waters, to find measures for its prevention, and to accurately monitor BWQ. For instance, an integrated approach of load estimation was used to determine pollution loads from nearby sources of domestic wastewater, runoff, and industrial wastewaters to estimate the total pollution load of Cartagena Bay in Columbia, and the study emphasizes the importance of calculating confidence intervals for each load value by combining different load estimation methods for land-based pollution loads in coastal areas (Tosic et al, 2018). In another study, remote sensing, and geographic information system (GIS) technologies were used together to assess pollution load on Burullus Lake via Landsat images.…”
