Abstract

That societal perceptions differ between use of the land and the ocean is exemplified by environmental regulations in the United States that allow much higher levels of chemical contamination in sewage sludge to be used on land than in dredged material to be dumped at sea. Criteria for sewage sludge acceptability for land application are bulk chemical concentrations. Criteria for acceptability of dredged material for disposal at sea focus upon biological testing for toxicity and bioaccumulation. The result is that sludge applied to land can have much higher levels of contamination than are commonly found even in sediments deemed unacceptable for disposal-at-sea. The inconsistencies between these criteria suggest re-evaluations of both.

    However, depending on their contamination levels, they can also be dumped at sea in compliance with international treaties (van Der Burgt, 1994) and international or national guidelines (DelValls et al., 2004). Dumping of dredged sediment at sea is currently one of the most acute problems in coastal zone management (O'Connor, 1998; Moog et al., 2015; Marmin et al., 2016) because it generates millions of tons of dumped sediments around the world (Mymrin et al., 2017), causing environmental problems in coastal and marine areas (e.g., Fredette and French, 2004; Bolam et al., 2006; OSPAR, 2008; Guerra et al., 2009; Cesar et al., 2014). Some of these problems are seafloor instability, deterioration of water quality (e.g., an increase in turbidity and nutrients) and changes in habitat, food chains, and fisheries in the marine environment and ecosystem (Zimmerman et al., 2003; Simonini et al., 2005; Lee et al., 2010).

    A first and direct effect is the covering of sediment and benthos compartments (mechanical effect), which leads to the destruction of local habitats at least temporarily (Chauvin et al., 1986; Olenin, 1992; Boutin, 2000; Desprez, 2000; Smith and Rule, 2001; Bolam et al., 2006a, 2006b; Hermand, 2008; Marmin et al., 2014, 2016a, 2016b; Dauvin et al., 2017b; Méar et al., 2018). The environmental impact of dredging activities is one of the most important problems in coastal zone management (O’Connor, 1998). Nevertheless, most scientific studies generally focus only on studying the structure of benthic invertebrates, in relation to their environment.

    The dumping of dredged materials represents one of the most important problems in coastal zone management and leads to major physical, sedimentological and biological disturbances (O’Connor, 1998; Essink, 1999; Marmin, 2013; Marmin et al., 2014).

    Numerous authors have studied the environmental impact of dredging activities (De Jonge et al., 2004; Van Raalte, 2006; Van Maren et al., 2014) or their morphological consequences (Monge-Ganuzas et al., 2013), but few have addressed the impact of spoils in the open marine environment. Moreover, the dumping of dredged materials is one of the most important problems in coastal zone management (O'Connor, 1998). The physical impact of dredge spoil on coastal ecosystems depends on the methods of dumping, the amount and manner of disposal (Newell et al., 1998), as well as the oceanographic conditions at the deposition site (Cole et al., 1999).

    Marine disposal of sewage sludge, a common practice worldwide, was discontinued in the USA and Europe following pollution abatement measures and ratification of international conventions (e.g. Ocean Dumping Ban Act (O'Connor, 1998; Swanson et al., 2004), OSPAR Convention (Whomersley et al., 2007), Barcelona Convention (http://www.unepmap.org/index.php?module=content2&catid=001001004)).
