Article
Persistent Organic Pollutants (POPs) are a global threat, but impacts of these chemicals upon remote areas such as Antarctica remain unclear. Penguins can be useful species to assess the occurrence of POPs in Antarctic food webs. This work's aim was the evaluation of polychlorodibenzo-p-dioxins and furans (PCDD/Fs), polychlorinated biphenyls (PCBs)...
Article
The aim of the present study was to assess the presence of perfluoroalkyl acids (PFAAs), namely perfluoroalkane sulfonates and perfluoroalkyl carboxylic acids, in Spanish river basins in order to: identify potential spatiotemporal variations; evaluate the effectiveness of the measures implemented for the reduction/elimination of these pollutants; v...
Article
The air humidity in Antarctica is very low and this peculiar weather parameter make the use of flame retardants in research facilities highly needed for safety reasons, as fires are a major risk. Legacy and novel flame retardants (nFRs) including polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDs), 1,2-bis(2,4,6-tribromophenoxy)...
Article
Sea-spray (or sea-salt) aerosol (SSA) formation and their subsequent atmospheric transport and deposition have been suggested to play a prominent role in the occurrence of ionizable perfluoroalkyl substances (PFAS) in the maritime Antarctica and other remote regions. However, field studies on SSA’s role as vector of transport of PFAS are lacking. F...
Article
Perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA) acids are ubiquitous in the oceans, including remote regions, and are toxic to fish and mammals. The impact to the lowest trophic levels of the food web, however, remains unknown. We challenged natural bacterial communities inhabiting Antarctic coastal waters (Deception Island) with PFOS...
Article
In this study, we evaluate the main factors driving the exposure of Southern Ocean seabirds to perfluoroalkyl substances (PFASs) across a wide geographic range. Five perfluoroalkane sulfonates (PFSAs, C4-12), 10 perfluoroalkyl carboxylic acids (PFCAs, C4-13), and perfluorooctane sulfonamide (FOSA) were analyzed in plasma (n = 128) from eight specie...
Article
Bird migration studies have been given added impetus recently thanks to the minia-turisation of tracking devices. However, tracking methodologies have remained impractical for the smallest pelagic species and so important gaps in knowledge still exist. In the case of the European Storm-petrel Hydrobates pelagicus, while Atlantic populations are tho...
Article
Time series (2008-2015) of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (dl-PCBs) in ambient air from the Spanish Monitoring Program were analyzed. A total of 321 samples were collected seasonally each year in 5 urban and 7 background sites by means of passive air sampling. Air concentratio...
Article
The Stockholm Convention (SC) on Persistent Organic Pollutants (POPs) calls for the Parties' effectiveness evaluation of those measures taken to meet the reduction and eventual elimination of POPs from the environment. With that goal, air concentrations of different POP families have been measured uninterruptedly since 2008 under the Spanish Monito...
Article
A simplified, miniaturised matrix solid-phase dispersion (MSPD)-based method allowing the simultaneous extraction and purification of contaminants belonging to selected families of regulated persistent organic pollutants (POPs), i.e. polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) and penta- to octa-polybrominated diphenyl ethers...
Article
Studies on Persistent Organic Pollutants (POPs) in Antarctic wildlife are scarce, and usually limited to a single locality. As a result, wildlife exposure to POPs across the Southern Ocean is poorly understood. In this study, we report the differential exposure of the major southern ocean scavengers, the giant petrels, to POPs across a wide latitud...

The use of flame retardants (FRs) is a common practice to avoid the flammability of consumer goods like textiles, furniture, foams, electronics and building materials. FRs exhibit environmental persistence and long range transport potential, behaving like persistent organic pollutants (POPs). Due to their global occurrence, bioaccumulation potentia...
Article
Within the framework of the Spanish monitoring program, this study reports on air concentration of DDTs, HCB, HCHs, NDL-PCBs, DL-PCBs, PCDD/Fs and PBDEs measured during the five-year sampling period 2008-2013. Spanish coastal remote and urban locations were studied using PUF disk passive air samplers which were deployed and collected every three mo...
Conference Paper
Perfluoroalkylated substances (PFASs) have received worldwide attention due to their widespread occurrence, toxicity and bioaccumulation potential. Most PFASs are extremely persistent in the environment, even if they exhibit high water solubility and lipophobicity compared to legacy persistent organic pollutants (POPs). Previous studies report thei...
Article
In this study, perfluoroalkylated substances (PFASs) were analyzed in 92 surface seawater samples taken during the Malaspina 2010 expedition which covered all the tropical and subtropical Atlantic, Pacific and Indian oceans. Nine ionic PFASs including C6-C10 perfluoroalkyl carboxylic acids (PFCAs), C4 and C6-C8 perfluoroalkyl sulfonic acids (PFSAs)...

Perfluoroalkylated substances (PFASs) are environmental contaminants that have received worldwide attention due to their widespread occurrence1, 2. Most PFASs are extremely persistent in the environment, but compared to legacy persistent organic pollutants, they have high water solubility and lipophobicity3. Even though there are previous studies r...

Introduction The Stockholm Convention (SC) on Persistent Organic Pollutants (POPs) is a global treaty to protect human health and the environment from POPs. These highly toxic chemicals remain in the environment for long periods, and are bioaccumulative and ubiquitous since they undergo long-rate transport. The SC, which was adopted in 2001 and ent...
Article
Aim: Intraspecific variability in the migratory movements of seabirds is being revealed far more complex than hitherto recognized, and our lack of understanding undermines their effective protection. Our aim is to test whether the isotopic values of a single feather of two threatened seabirds, the Mediterranean (Puffinus yelkouan) and the Balearic...
Article
Dechlorane Plus (DP) and some of its possible degradation products were measured in eggs from the yellow-legged gull (Larus michahellis) and Audouin's gull (Larus audouinii) from a protected area in the southwestern Mediterranean Sea. Statistically significant differences were found between both gull species, with yellow-legged gull eggs showing th...

ABSTRACT: Trophic ecology and movements are critical issues for understanding the role of marine predators in food webs and for facing the challenges of their conservation. Seabird foraging ecology has been increasingly studied, but small elusive species, such as those forming the ‘little shearwater’ complex, remain poorly known. We present the fir...
Article
Trophic ecology and geographic location are crucial factors explaining OC levels in marine vertebrates, but these factors are often difficult to disentangle. To examine their relative influence, we analyzed PCBs, DDTs and stable-nitrogen isotope signatures (δ15N) in the blood of 10 pelagic seabird species across 7 breeding localities from the north...

Article
Although seabirds have been proposed as useful biomonitors for organochlorine contaminants (OCs) in marine environments, their suitability is still unclear. To understand the geographic variability and the influence of seabird trophic ecology in OC levels, we analyzed PCBs, DDTs, delta(13)C, and delta(15)N in the blood of adult Calonectris shearwat...

The existence of two seasonally distinct breeding populations of Oceanodroma storm-petrels in the Azores islands was first documented in 1996. The discovery of morphological differences between the populations led to the suggestion that they may represent cryptic sibling species. Recent mtDNA and microsatellite analysis from storm-petrel population...

Polycyclic aromatic hydrocarbons (PAHs) are well-known widely distributed environmental contaminants with toxic, mutagenic, and carcinogenic properties. Their hydrophobic properties and low biodegradability cause accumulation in organisms. Since most seabirds are placed at the uppermost trophic level of the marine food webs important toxic effects...
