“…The general trend of decreasing values in pH concentrations found in the study, could be further associated to the environmental changes described for the BBE as part of the global change effects on biogeochemical processes in estuaries (Kopprio et al, 2015). Additionally, the increasing concentration of CO 2 gases as a consequence of the greenhouse effect might also lead to increasing CO 2 concentration in the seawater and thus a decrease in pH (Piccolo, 2013).…”

“…SWA estuaries located in the Pampean biome extends > 1000 km and are characterized by variable morphology and hydrography (Piccolo and Perillo, 1999) (Table 1). Samborombón estuary (SAM) is a microtidal estuary that corresponds to Samborombón-Salado system; its wetland area was declared a Ramsar site due to its importance for biodiversity conservation (Kopprio et al, 2015). Anthropogenic chemical impacts reported in SAM and adjacent areas are related to eutrophication, heavy metal and OCPs pollution (Colombo et al, 2005;Kopprio et al, 2015).…”

“…Besides, many of these coastal environments serve as nesting and feeding habitats for many species, among other ecosystem services, being protected natural areas of regional and global concern (Kopprio et al, 2015). Several studies reported the occurrence of PCBs and OCPs in sediment, water and vertebrate species from SWA estuaries (Colombo et al, 2005;Gonzalez et al, 2013;Tombesi et al, 2017).…”

Southwest Atlantic (SWA) estuaries have been historically impacted by industrial and agricultural activities that represent an important source of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs). Intraspecific differences in OCPs and PCBs levels were evaluated in the benthic polychaete Laeonereis culveri from SWA estuaries (Samborombón; Mar Chiquita; Quequén Grande and Bahía Blanca) at different spatio-temporal scales. Regarding inter-and intra-estuarine spatial comparisons polychaetes showed significant differences in OCPs/PCBs levels (p < 0.05) being DDTs, endosulfan, penta-and hexa-CBs homologues the most representative compounds. Intra-estuarine comparisons also showed significant differences in terms of seasonality and body size (p < 0.05). OCPs/PCBs concentrations were negatively correlated with animal weight, but this covariable was not relevant on differences observed. OCPs/PCBs levels in polychaetes showed strong relationships with those of sediments, being suitable for estuarine biomonitoring studies. Seasonal and body-size differences found in OCPs and PCBs levels in tissues reveal the importance of these factors for intra-estuarine monitoring.

Solo basta recordar algunos casos como el Río de la Plata, que acoge a una importante cantidad de la población urbana de Argentina y Uruguay (Buenos Aires, Montevideo) EcoPlata, 1999;Pérez-Cayeiro & Chica-Ruiz, 2015), o el estuario de Bahía Blanca (Argentina) que sufre una rápida expansión urbana en sus márgenes como consecuencia del desarrollo portuario y la instalación de grandes industrias (Dadon, 2010;Kopprio et al, 2015).…”

RESUMENLas áreas litorales de América Latina y Caribe (ALC) se encuentran cada vez más afectadas por los asentamientos humanos. La expansión urbana conlleva un importante cambio en los usos del suelo, especialmente sobre el litoral. La presente investigación analiza este proceso desde un punto de vista cualitativo y cuantitativo. Se estudia la evolución de la población en todas las ciudades de ALC mayores a 100.000 habitantes, litorales e interiores entre 1945 y 2014. El método empleado relaciona diferentes fuentes de información de las bases de datos de Naciones Unidas con las imágenes de sensores remotos de Google Earth. De esta forma es posible perfi lar ciertos fenómenos urbanos y costeros en ALC. Los resultados muestran un litoral de ciudades pequeñas y próximas a unidades fi siográfi cas y ecosistemas vulnerables como bahías, estuarios o bosques de manglar. El resultado obtenido pone de manifi esto algunas prioridades de gestión para las áreas litorales en la región de ALC. Palabras clave: América Latina y Caribe, ciudades costeras, cambio litoral, ecosistemas costeros, presiones urbanas ABSTRACTCoastal areas in Latin America and the Caribbean (LAC) are increasingly affected by human settlements. Urban expansion involves a signifi cant change in land use, especially in the coastal area. This research analyses this process from a qualitative and quantitative perspective. Population evolution is studied in all LAC cities with greater than 100,000 inhabitants, differentiating the coastal cities and the interior ones, from 1945 to 2014. The method relates different information sources; from United Nations databases and images from remote sensing. This allows obtaining different urban and coastal process in Latin America and the Caribbean. The results show a coastal area with small cities located close to fragile ecosystems, such as bays, estuaries and mangrove forests. Results obtained highlight management priorities for coastal areas in the LAC region.
