Biomonitoring using birds of prey as sentinel species has been mooted a way to evaluate the success European Union directives that are designed protect people and environment across Europe from industrial contaminants pesticides. No such pan-European evaluation currently exists. Coordination large scale monitoring would require harmonisation multiple countries types samples collected analysed-matrices vary in ease with which they can be information provide. We report first ever assessment...
Biomonitoring using raptors as sentinels can provide early warning of the potential impacts contaminants on humans and environment also a means tracking success associated mitigation measures. Examples include detection heavy metal-induced immune system impairment, PCB-induced altered reproductive impacts, toxicity with lead in shot game. Authorisation such releases implementation is now increasingly delivered through EU-wide directives but there little established pan-European monitoring to...
Apex predators are good indicators of environmental pollution since they relatively long-lived and their high trophic position spatiotemporal exposure to chemicals provides insights into the persistent, bioaccumulative toxic (PBT) properties chemicals. Although monitoring data from apex can considerably support chemicals' management, there is a lack pan-European studies, longer-term in organisms higher levels. The present study investigated occurrence contaminants emerging concern (CECs) 67...
Birds of prey, owls and falcons are widely used as sentinel species in raptor biomonitoring programmes. A major current challenge is to facilitate large-scale by coordinating contaminant monitoring activities building capacity across countries. This requires sharing, dissemination adoption best practices addressed the Networking Programme Research Monitoring for with Raptors Europe (EURAPMON) now being advanced ongoing international COST Action European Raptor Biomonitoring Facility. The...
A study carried out in the Oldman River watershed southern Alberta, Canada, to delineate potential surface water pollution sources revealed that use of conventional raster-based digital elevation models (DEMs) and flow-direction algorithms resulted delineation incorrect boundaries. The inaccuracies from resolution available DEM, which is too coarse represent presence anthropogenically modified terrain features, such as roads, ditches canals, can significantly alter overland flow paths. This...
Abstract Monitoring data from apex predators were key drivers in the development of early chemicals legislations due to population declines many species during twentieth century, which was linked certain persistent organic pollutants (POPs). Besides triggering global treaties (e.g. Stockholm Convention), chemical monitoring have been particularly important for identifying compounds with bioaccumulative properties under field conditions. Many are protected and only a few environmental...
Long-term trends in alpine and prairie snow pack accumulation melt are affecting streamflow within the Oldman River Basin southern Alberta, Canada. Unchecked rural urban development also has contributed to changes water quality, including enhanced microbial populations increased water-borne pathogen occurrence. In this study we look at changing environment its impact on quality quantity. The cumulative effects include a decline net supplies, declining resulting risk of disease. Our data...
Abstract A large number of apex predator samples are available in European research collections, environmental specimen banks and natural history museums that could be used chemical monitoring regulation. Apex predators bioaccumulate pollutants integrate contaminant exposure over spatial temporal scales, thus providing key information for risk assessments. Still, present assessment practices under the different legislations hardly use existing data from top predators. Reasons include lack...
Abstract The chemical industry is the leading sector in EU terms of added value. However, contaminants pose a major threat and significant costs to environment human health. While legislation international conventions aim reduce this threat, regulators struggle assess manage risks, given vast number substances involved lack data on exposure hazards. European Green Deal sets ‘ zero pollution ambition for toxic free ’ by 2050 Chemicals Strategy calls increased monitoring chemicals environment....
Second-generation anticoagulant rodenticides (SGARs) are widely used to control rodent populations, resulting in the serious secondary exposure of predators these contaminants. In United Kingdom (UK), professional use and purchase SGARs were revised 2010s. Certain highly toxic have been authorized since then be outdoors around buildings as resistance-breaking chemicals under risk mitigation procedures. However, it is still uncertain whether how regulatory changes influenced birds prey SGARs....
Abstract Gridded estimates of daily minimum and maximum temperature precipitation from 1960 to 2005 were prepared for the Okanagan Basin British Columbia. The procedure utilized available climate data 182 stations employed a regression based interpolation scheme at 500 metre grid spacing. Spatial distribution took into account variations in with elevation, an observed north-south gradient, proximity several large lakes valley bottom. An inverse distance weighting was used interpolation,...
Abstract Despite the key role of raptors (including birds prey Falconiformes and owls Strigiformes) in ecosystems their sensitivity to environmental change, a well coordinated, Europe-wide monitoring is lacking. EURAPMON, Research Networking Programme European Science Foundation, was launched with aim establishing sustainable Europewide network for raptors. An overview current schemes raptor populations 28 countries, as reported by EURAPMON National Coordinators at workshop Murcia (Spain)...
Abstract This paper provides a novel survey of current collections frozen raptor carcasses and tissue samples in natural history museums (NHMs), environmental specimen banks (ESBs) other research (ORCs e.g. at universities institutes) across Europe assesses the extent to which might support pan-European biomonitoring through provision for contaminant analyses. The is based on questionnaire responses received late 2018 early 2019 from 116 institutions. Issues covered include number diversity...
Trace elements are chemical contaminants spread in the environment by anthropogenic activities and threaten wildlife human health. Many studies have investigated this contamination apex raptors as sentinel birds. However, there is limited data for long-term biomonitoring of multiple trace raptors. In present study, we measured concentrations 14 essential non-essential livers common buzzard (Buteo buteo) collected United Kingdom from 2001 to 2019 whether changed during period. addition,...
Using monitoring data from apex predators for chemicals risk assessment can provide important information on bioaccumulating as well biomagnifying in food webs. A survey among European institutions involved chemical their experiences with predator revealed great interest using such data. However, the respondents indicated that constraints were related to expected high costs, lack of standardisation and harmonised quality criteria exposure assessment, access, regulatory...
