Estuaries and coastal marine waters are acknowledged as the aquatic systems with the highest pollutionimpactsince the wide majority of countries havean 80 to 100 percentageof their population living close to the coastline, within the first 100 km, and with average population densities of over three times the global mean(Deycard et al.2014). Human burden on the coasts enhance pressure on these coastal ecosystems through habitat conversion, infrastructure for manufacturing, waste products disposal, among others (Martínez et al. 2007).Moreover, the rapid population growth without a proper planning creates problems with the disposal of the waste produced which shown a significant increased. As the discharge and dumping of waste in coastal environments is nowadays being closely monitored, increasing pressure is expected on the deep open ocean as a final repository of waste and unwanted substances from a variety of human activities (Kennish 1997; Mengerink et al. 2014).
