why worry about marine litter ?

DAMAGE economic

economical damage from litter: possibly over 1.000.000.000 Euro per year !

DAMAGE ecological

Northern Fulmar – Fulmarus glacialis

Lesser Black-backed Gull

Northern Fulmar

• talrijk, wijdverspreid, dode vogels op strand• eet allerlei soorten afval• fourageert alléén maar op open zee• hoopt plastic afval op in de maag• integreert vervuilingsniveaus in zijn voedselgebied op zee

Stormvogels zijn dom

maar juist daarom misschien …

een handige graadmeter voor

afval op zee

North Sea Regional Pattern (EcoQO performance 2005-2009)

The pattern indicates major local sources of pollution (rather than ‘ background’ from e.g. Gulf Stream)

The southern area, in particular the Channel, is most heavily polluted: ±twice the level of that in the Scottish Islands

in regions where fulmar sampling is not possible other options for bio-monitoring have to be explored

HARM?

Fulmar wreck 2004:highly unusual sex & age

compositionserious deficiencies in down

plumage illogical reproductive decisions

Suggesting a disturbed endocrine hormonal system !

Hormonal disruptions are a known effect of the types of contaminants accumulated by fulmars through food and/or plastic ingestion

From Honolulu 2011 5IMDC presentation: Chemicals in marine plastics and risks: a mass mortality incident among fulmars in 2004 showed many characters of hormonal disturbance,

potentially related to plastic ingestion

Fulmar is a

high quality scientific toolplus a

strong public relations tool

to create the political and public awareness that is essential to accept and support measures

aimed at the reduction of litter in the marine environment
