Prestige

AThe accident with the Prestige ship in Galicia, Spain INTRODUCTION 13 November 2002, Oil tanker Prestige (Bahamian flag) 77,000 tons of heavy fuel oil with a

high sulphur content:Issued an SOS off Cape Finisterre, as it was navigating at the mercy of the sea.

The crew was evacuated and the tanker towed:

impossible to take it into a safe harbour,

it was decided to tow it out to sea.

The accident with the Prestige ship in Galicia, Spain INTRODUCTION

Weather conditions: very extreme,

A crack appeared in the hull and gradually became larger

Until the vessel split in half, six days after, (19 Nov)

at a distance of 130 miles from Cape Finisterre

19 November

The stern sunk four hours after

And the bow four hours later

AThe accident with the Prestige ship in Galicia, Spain INTRODUCTION

Response:fishermen tried to remove all of the oil they could by using their bare hands or any kind of tool available

Response:

in order to prevent it from reaching the shore and entering into the Galician Estuaries (very rich in seafood).

a unique experience

AHigh toxicity:

(Russians): heavy fuel oil no. 2 or (British): no. 6 or hold fuel used basically for industrial purposes (thermal power stations, furnaces, etc.) obtained from residual fuel oil mixed with gas oil and diesel oil high sulphur content (2.58%) polycyclic aromatic hydrocarbons (PAHs), other hydrocarbons and heavy metals

characterised by its low volatility and solubility in water, high viscosity and adherence and a very lengthy degradation time

What could happen with this manipulation to the people?

High toxicity:Hydrocarbons with high sulphur content (PHAs)Taking account the:

composition of the product, the intensity and duration of the contact, the pathway of entry, the individual characteristics of the person exposed

It can enter our bodies by:inhalation, affecting the respiratory and digestive tracts, or by direct contact with the skin and mucous membranes

Surely, due to the geographical limits of our sample, this meant that:

care was provided to much more people than what official cyphers said.

A JUSTIFICATION

AAs a result of the foregoing:

keeping in mind that thousands of people were involved and that we lack experience in disasters of this kind,

JUSTIFICATION

we considered it advisable to prevent and also to study:

the acute morbidity, both the direct as well as the indirect,derived from the cleanup of the black tide that washed up on our shores

JUSTIFICATION

we considered it advisable to prevent and also to study:the acute morbidity, both the direct as well as the indirect,derived from the cleanup of the black tide that washed up on our shores

in order to be: better prepared in the event of the reoccurrence of a similar situation or to contribute our knowledge to assist any other area that may find itself immersed in a similar tragedy in the future.

JUSTIFICATION

General: To ascertain the acute morbidity derived from the cleanup work for removing the spill caused by the Prestige on the Galician coast.

Specific:To quantify and classify the acute cases treated.

To identify preventive measures capable of minimising the health problems derived from such cleanup activities.

OBJECTIVES

A MATERIAL AND METHODS:

AAn observational, descriptive study, based on the collection of data, on a standard and the 061 emergency care checklist, with respect to all of the people attended to in the primary care health centers and emergency services who were involved in the fuel oil cleanup.

A research group (Boiro Outpatient Emergency Service) was set up to perform the study, and the cooperation of the Primary Care Health centers and Outpatient Emergency Services of Rianxo, Poboa do Caramiñal, Riveira, Porto do Son, Noya, Padrón and Muros.

MATERIAL AND METHODS:

AThe field work: performed from November 02 - April 03.Statistical analysis: Input of the data was later effected on computer support, and performed a statistical analysis of variables noted on checklists.

Percentages were determined for the qualitative variables, while central trend and dispersion measurements were obtained for quantitative variables.

MATERIAL AND METHODS:

A RESULTS:

A1.-SUBJECTS:

982 people were treated (67% males vs 32% females); age average 26 (96% 18-40 years of age)

2.-PATHOLOGIES (cases): Eye irritations: 156 (16%). Skin irritations: 134 (14%). Traumatisms: 126 (13%). Pharyngeal irritations: 116 (12%). Colds and flu: 111 (11%). Nausea and vomiting: 87 (9%). Back pain: 82 (9%). Headache&general complaints: 78 (8%). Respiratory difficulties: 64 (7%). Gastric disorders: 16 (1%). Others: 12 (1%).

RESULTS:

It must be noted that:- 47 presented 2 or more pathologies at the same time (quantified as a single case and classified under the more or most serious pathology).- 34 were referred to hospital care (23 traumatisms, 7 respiratory insufficiency, 4 other reasons)…

... RESULTS:

A3.-CONCOMINANT PATHOLOGIES: Respiratory difficulties (64 cases:48 -75%- had

asthma or bronchial hypersensitiv); Skin irritations (134 cases: 72 ,- 54%- were

allergic). Back pain (82 cases: 38 -46%- had a lumbago

background). 4.-CHRONOLOGY: the major part of the demand

for emergency care occurred between 5 Dec and 6 Jan (15-45 days after):

694 cases were treated (70.67%).5.-PROTECTION EQUIPMENT: the majority of

those treated up to the end of December had not used any kind of protection whatsoever.

... RESULTS:

A CONCLUSIONS:

A1.- The major part of the demand for health

care was due to the lack of coordination, information and means of protection during the first month following the tragedy.

CONCLUSIONS:

2.- The most serious pathology was that derived from accidents, either by falls or by blows with the utensils or containers used in the cleanup work.

CONCLUSIONS:

2.- The most serious pathology was that derived from accidents, either by falls or by blows with the utensils or containers used in the cleanup work.

3.- The most prevalent pathology treated involved skin and mucous membrane irritations (406 cases, 41.34%).

ENVIRONMENTAL ISSUES:ANALISE DE ORGANISMOS

Fases principais do programa: a) Fase de evaluación: para determina-lo grado inicial

de afectación dos organismos. Permite información para calendarios de apertura das zonas onde a actividade extractiva está prohibida.

b) Establecemento dun programa de control permanente, para a determinación da presencia de derivados de hidrocarburos nas zonas de producción.- Nunha primeira etapa permitiría o seguimento do vertido e, - Posteriormente, detectaría os cambios na situación das augas costeiras respecto á presencia de HC (importante para o control de vertidos de pequena magnitude, contaminación mariña asociada a actividades portuarias, etc.)

Parámetros a considerar neste programa:

a) Concentración de hidrocarburos totais na columna de auga, dende la superficie ó fondo.

b) Examen visual dos organismos.

c) Examen organoléptico dos organismos.

d) Análises do contido de derivados dos hidrocarburos (PAH´s) nos organismos.

A) Contido de hidrocarburos totais na columna de agua.

Obxetivos: • Avalia-las concentracións de hidrocarburos disoltos nas

augas das distintas zonas dende a superficie ata o fondo. • Determina-las diferencias entre as distintas zonas de

producción. • Coñece-los cambios que se produzan no tempo.

Caracteristicas:• Periodicidade semanal• Toma de mostras en toda a columna de auga de 38

estacions nas rías de Vigo, Pontevedra, Arousa e Muros (con posterioridade extendeuse a toda a costa de Galicia).

PROBING: Feb 20th (3 months after the disaster)

B) Examen visual dos organismos:

Obxetivos: Avalia-lo grado de afectación directa por hidrocarburos nos organismos.

Procedemento Operativo (si examen visual positivo): • Solicitase informe sobre o estado da zona de producción (presencia de fuel nas augas e fondos, afectación das zonas rocosas próximas, etc.) os Servicios de Asistencia Técnica da Consellería de Pesca e Asuntos Marítimos.• En función do informe:

- Zona afectada: peche ou mantemento do peche; no se continúan as restantes análises sobre os organismos.

- Zona libre de hidrocarburos: mantemento da situación actual (pechada ou abierta) e continuación das análises.

C) Examen organoléptico dos organismos.

Obxetivos:• Avalia-lo grado de afectación por hidrocarburos dos organismos.• Impedi-la incorporación á cadea alimentaria humana de productos nos que un consumidor medio poida detectar sabor/olor a derivados dos HC.

Características:• Análise do olor a fuel en crudo e tras cocción, e sabor a fuel tras cocción.• En función dos resultados, clasificanse como Aptas, Dudosas e Non Aptas.• As análises son realizadas por un panel de catadores, altamente especializados e cada mostra é analizada cando menos por 15 catadores.• As analises organolepticas estanse realizando mediante convenio coa Facultade de Veterinaria en Lugo, da Universidade de Santiago. - Actualmente estase en fase de entrenamiento e fixación dos niveis de detección e nivel umbral, para a apertura ou peche das zonas de producción.

D) Contido de derivados de hidrocarburos (PAH´s).

Obxetivos:• Cuantificar analíticamente as concentracions de PAH´s acumuladas nos organismos.

Características: • Límite de contido en PAH´s para a apertura-peche das zonas de producción fixado pola Agencia Española de Seguridad Alimentaria en colaboración coa OMS.• Os resultados, no momento actual, son o criterio determinante para a apertura-peche das zonas de producción.

... D) Contido de derivados de hidrocarburos (PAH´s).

NIVELES TOLERABLES? - Unión Europea non ten establecidos límites para os residuos de PAH. - De acordo con expertos de: Agencia Española de Seguridad Alimentaria (AESA), Organización Mundial de la Salud, e outras Consellerías e CC.AA:Nas zonas de producción, dos 6 PAH principais: Benzo(a)antraceno, Benzo(b)fluoranteno, Benzo(k)fluoranteno, Benzo(a)pireno, Dibenzo(a,h)antraceno, Indeno (1,2,3-cd) pireno : • Moluscos (peso seco): 200 microgramos/quilo,.• Moluscos (peso de tecido fresco de parte comestible): 40 microgramos/quilo (a materia seca equivale a un 20% do peso fresco) • Peixes (peso seco): 20 microgramos/quilo • Peixes (peso fresco): 100 microgramos/quilo.

• Por las estimaciones realizadas en catástrofes similares (Erika, Braer, Exxon Valdez, Treasurer, Amocco Cadiz, etc.) sobre la cantidad de aves encontradas con respecto al total afectado, para el caso del Prestige oscilan entre el 15 y el 50%

• Estimando el número de aves marinas severamente afectadas en la banda baja (una estima conservadora), situaría el porcentaje entre el 10 y el 20%:

Por tanto, considerando que se han recogido un total de 23.181 aves entre vivas y muertas, en las costas de España, Portugal y Francia, se puede estimar que: el número de aves marinas afectadas por el fuel del “Prestige” oscila entre las 115.000 y las 230.000 aves.
