Northern Fulmar – Fulmarus glacialis

Northern Fulmar

Page 8: PLASTIC SOUP - WUR

• numerous, widely distributed, beached birds available• consumes all sorts of litter • feeds exclusively at sea• retains litter in stomach• integrates pollution levels over its oceanic foraging range

Fulmars are

fools ….but because

of that they may be

a convenient ‘tool’ for monitoring:

EcoQO on marine litter (plastic) in the North Sea

Quality elementbeached Northern Fulmars

Objective (‘target’):the proportion of Fulmars with more than 0.1g of plastic in the stomach must be less than 10%(all regions, for at least 5 years)

EcoQO Compliance or Performance =the percentage of birds in a sample that have 0.1 g or more plastic mass in the stomach

OSPAR EcoQOs - Ecological Quality Objectives

North Sea Regional Pattern (EcoQO performance 2005-2009)

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

Gulf Stream)

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

“member states shall take the necessary measures to achieve or maintain good environmental status in the marine environment by 2020 at the latest

Litter descriptor:“ properties and quantities of marine litter do not cause harm to the coastal and marine environment”

Indicators for litter descriptor: Trends in quantities on beach, in water and microplastics and in ‘impact of litter on marine life *

* = measured by ingestion by animals as in Fulmar example

European MSFD 2008(Marine Strategy Framework Directive):

Page 19: PLASTIC SOUP - WUR

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

RATE OF BREAKDOWN AND GUT PASSAGE OF PLASTIC IN DIGESTIVE SYSTEMS OF PETRELS ESTIMATED AT 75 % OF AVERAGE STOMAGE CONTENT PER MONTH

‘processed’ = reduced to mm size and below uptake of breakdown products in gut excretion as microplastics, partially in other habitats

Effects on all marine life and ultimately man are

extremely complex and uncertain !!

Priority Actions 

REDUCE – REUSE – RECYCLE Make deposit & return systems legally required: high deposit fees

for ALL products containing plastic must be standard.

Forbid the production of so-called degradable or compostable packaging for both fossil- or bio-sourced

Make strong legislation on toxicity of compounds used in plastic production (also of non-food plastics)

Let plastic be plastic! Create value on plastic ‘waste’

Use common sense in addition to scientific evidence
