IEO


IEO is the Oceanographic Spanish Institute, created in 1914. It is a public reaserch organism devoted to the investigation of oceanography, the knowledge about oceans, sustainability of fisheries and aquaculture resources and the marine environment. IEO depends on Ministerio de Ciencia, Innovación y Universidades.

The work to be carried out in PLAS-MED project includes:

  • The optimization the analytical method for the determination of contaminants of emerging concern in biota, the characterization of their sorption, biodegradation and bioaccumulation kinetic in the marine environment
  • Determine the environmental distribution of contaminants of emerging concern in the Ebro Delta and the Mar Menor lagoon.
  • Effects of contaminants of emerging concern on mussels and other organisms, evaluating the influence of microplastics in these processes
  • The optimization of technics to investigate immune responses in mussels and to characterize the modulation that occurs in these processes due to the influence of microplastics.

People involved in PLAS-MED project:

Dr. Víctor León (PI at IEO)

email: victor.leon@ieo.es

The research lines developed by Víctor M. León León are:

a) Optimize and validate analytical methods for the determination of regulated organic pollutants and contaminants of emerging concern in water, sediment and biota, and more recently also in plastics.

b) Characterize of the distribution and bioaccumulation of regulated pollutants and contaminants of emerging concern in the marine environment, as a way to identify those with the greatest impact.

c) Characterize the behavior of organic pollutants, microplastics and their effects in the marine environment through laboratory tests under controlled conditions (sorption, degradation, bioaccumulation, etc.).

This work is developed through national (DECOMAR CTM2008-01832, IMPACT CTM2013-48194-C3, etc.) and international research projects (BASEMAN PCIN-2015- 170-C02-02, etc.) and also through the advice to the central administration in marine pollution, for example in the assessment of the state of the marine environment in the Mediterranean area required by the Marine Strategy Framework Directive.

Dr. Concepción Martínez-Gómez

The research lines developed by Concepción Martínez-Gómez are:

a) Development and validation of biomarkers of exposure and effects (in vivo-in vitro) related to chemical contamination and microplastics in fish and marine invertebrates and in their tissues (bile, hemolymph).

b) Development and validation of "in vitro" bioassays to evaluate the toxicity associated with water and marine sediments.

c) Characterization and assessment of biological responses (biomarkers) in the marine environment against chemical and microplastic contaminants.

d) Development of environmental assessment criteria of biomarker responses in fish and marine invertebrates applicable to the Mediterranean Region.

e) Study of the immune response in mussels by means of laboratory tests under controlled conditions ("in vivo" - "in vitro" bioassays).

These lines of research have been developed through national research projects (CRISISMAR CTM2009-10908, DECOMAR CTM2008-01832, IMPACT CTM2013-48194-C3, PLAS-MED CTM2017-89701-C3-3-R, etc.) (TOXPROF ERAC-CT2005-016165, EPHEMARE PCIN-2018-187-C03-01 etc.), advising to the central administration (i.e. assessment of the state of the marine environment in the Mediterranean area required by the Framework Directive Marine Strategy), and participating in international working groups and workshops on the integrated study of the biological effects of marine pollution (ICES / WGBEC, ICES / OSPAR ICON Workshop, UNEP / MAP).
