“…Marine ecosystems are the final receptors of an immense set of pollutants, and several biomonitoring programs have already been developed and implemented in the Atlantic area (Stagg, 1998;Roose and Brinkman, 2005). The use of biomarker data for detecting pollutant exposure is an old idea (Peakall, 1992;Heath, 1995), but the recognition of natural variability (seasonal and spatial, for example) is the first step toward the need of setting up baseline values for biomonitoring programs.…”

Sardina pilchardus is a marine species common in the North Atlantic Ocean, and is subjected to diffuse anthropogenic chemical contamination and seasonal fluctuations in biotic and abiotic parameters that may alter its physiology and condition. Biological material is easily available through commercial fisheries, which could facilitate its use as a bioindicator species. The aim of the present work was to address its potential inclusion in biomonitoring studies, considering a combinatory approach through the use of enzymatic biomarkers and somatic indices, by assessing spatial and temporal patterns in a metapopulation along the west coast of Portugal. Our results showed significant variability of the biochemical and physiological profile of the fish, mainly concordant between sampling sites. Large differences for most markers were found across periods of the year, showing the importance of seasonality, which was mostly related to the reproductive cycle. Hence, environmental scientists should acknowledge seasonality as a strong driving force for physiological adaptations, influencing biochemical markers that are normally used to identify effects of chemical contamination. The here-obtained set of data suggests that S. pilchardus may be successfully included in oceanic biomonitoring studies, when one considers that the contribution of seasonal factors may exceed the influence of eventual anthropogenic contamination.

“…The majority of studies to date have focused mainly on single tests, for example assessing lysosomal membrane stability (LMS) to test for the activation of catabolic processes or measuring glutathione peroxidase levels to test for oxidative stress (Tsangaris et al 2007). These types of approaches have previously been used in international marine biomonitoring programmes such as MEDPOL phase III, RAMOGE and OSPAR (Roose & Brinkman 2005). However, they have proven to be of limited success due to the small number of responses assessed and the variability inherent in all biological/ecological studies.…”

Monitoring of the marine environment is crucial for determining the impact of environmental stressors and/or pollution on ecosystem health. Classical assays that traditionally focus on a limited number of selected endpoints have thus far proven to be of limited success in this regard. Here, we apply 1 H-nuclear magnetic resonance (NMR)-based chemometric analysis to the marine mussel Mytilus galloprovincialis to investigate changes in the metabolic profile of digestive gland tissue as a response to exposure to nickel and chlorpyrifos, both as single chemicals and as a mixture. The multivariate data was analysed by principal component analysis and partial least-squares discriminant analysis. The major metabolite changes responsible for the spectral differences observed were related to amino acid, nucleotide and methylamine metabolism in all 3 cases. In addition, novel metabolic profiles were associated with exposure to each chemical and the mixture. Nickel produced changes in energy metabolism while chlorpyrifos resulted in an increase in acetylcholine levels. Mussels exposed to a single compound demonstrated a significantly different response to those given the mixture, where a small antagonistic effect was evident. The study demonstrates the potential of NMR-based metabolomics to provide a rapid and cost-effective screening tool for monitoring the aquatic environment.KEY WORDS: Antagonism · Metabonomics · Metabolomics · Mussels · Pollution · Nickel · Chlorpyrifos Resale or republication not permitted without written consent of the publisherMar Ecol Prog Ser 369: [169][170][171][172][173][174][175][176][177][178][179] 2008 molecule metabolites to be considered simultaneously. NMR-based metabolomics is becoming increasingly prevalent in environmental toxicology research, particularly in terrestrial studies (Griffin & Shore 2007). The uses and applications of this technique in marine science to date are limited but are summarised in Viant (2007).Mussels are well-suited to metabolomic analysis for environmental toxicology. They have a wide geographical distribution in both salt and freshwaters and, as sessile, filter-feeding organisms, they are exposed to and bio-accumulate many different classes of environmental contaminants. This, in conjunction with their importance as a food organism to humans, means they are widely used in ecological and bio-monitoring studies (Viarengo & Canesi 1991, Cajaraville et al. 2000. Therefore integrating ecotoxicogenomics-based data derived from metabolomics into environmentally relevant results is likely to be much easier for these species than for many others.In the present study, we applied 1 H-NMR-based metabolomic and chemometric analysis to the marine mussel Mytilus galloprovincialis. Changes in the metabolic profile of digestive gland tissue as a response to exposure to the heavy metal nickel (Ni) and the organophosphorus insecticide chlorpyrifos (Chlp), both singly and as a mixture, were assessed. Both compounds occur in the marine environment and their effects ar...

“…The determination and quantification of PAHs in sediment samples can be performed using extraction with acetone/n-hexane [41] and applying GC-MS [42]; extraction by a Soxhlet apparatus [43] and analysis GC-MS [44] with a capillary column; an extraction and fractionation technique based on the SW-846 test methods while quantification and qualification of PAHs are performed by the modified method of USEPA 8270 [45] by a capillary gas chromatograph [19]; an extraction procedure by using pressurized solvent [46] while PAHs fractionation and analysis is performed by activated silica gel column and a GC-MS [47,48]; extraction and purification by gel permeation chromatography and analysis by HR GC-MS [49]; following the EPA Method 8310 and using for analysis HPLC with ultraviolet and fluorescence detectors� PCBs are environmental contaminants regulated by the Stockholm Convention of POPs) [50], and are included on the OSPAR List of Chemicals for Priority Action due to their persistence, potential to bioaccumulation, and toxicity. The determination of PCBs in sediment generally involves extraction with organic solvents [51,52], clean-up and gas chromatographic separation with electron capture detection or mass spectrometry [53]. There is also the EPA-Method 8080 [54] providing gas chromatographic conditions for the detection of certain organochlorine pesticides and PCBs at mass fraction of μg·kg .…”
