Alternative and legacy flame retardants in marine mammals from three northern ocean regions
- 2023
-
In: Environmental Pollution. - 0269-7491 .- 1873-6424. ; 335, s. 122255-122255

Journal article (peer-reviewed)abstract
- Flame retardants are globally distributed contaminants that have been linked to negative health effects in humans and wildlife. As top predators, marine mammals bioaccumulate flame retardants and other contaminants in their tissues which is one of many human-imposed factors threatening population health. While some flame retardants, such as the polybrominated diphenyl ethers (PBDE), have been banned because of known toxicity and environmental persistence, limited data exist on the presence and distribution of current-use alternative flame retardants in marine mammals from many industrialized and remote regions of the world. Therefore, this study measured 44 legacy and alternative flame retardants in nine marine mammal species from three ocean regions: the Northwest Atlantic, the Arctic, and the Baltic allowing for regional, species, age, body condition, temporal, and tissue comparisons to help understand global patterns. PBDE concentrations were 100–1000 times higher than the alternative brominated flame retardants (altBFRs) and Dechloranes. 2,2′,4,5,5′-pentabromobiphenyl (BB-101) and hexabromobenzene (HBBZ) were the predominant altBFRs, while Dechlorane-602 was the predominant Dechlorane. This manuscript also reports only the second detection of hexachlorocyclopentadienyl-dibromocyclooctane (HCDBCO) in marine mammals. The NW Atlantic had the highest PBDE concentrations followed by the Baltic and Arctic which reflects greater historical use of PBDEs in North America compared to Europe and greater industrialization of North America and Baltic countries compared to the Arctic. Regional patterns for other compounds were more complicated, and there were significant interactions among species, regions, body condition and age class. Lipid-normalized PBDE concentrations in harbor seal liver and blubber were similar, but HBBZ and many Dechloranes had higher concentrations in liver, indicating factors other than lipid dynamics affect the distribution of these compounds. The health implications of contamination by this mixture of compounds are of concern and require further research.

Review of life-cycle based methods for absolute environmental sustainability assessment and their applications
- 2020
-
In: Environmental Research Letters. - : IOP Publishing Ltd. - 1748-9326 .- 1748-9318. ; 15:8
-
Journal article (peer-reviewed)abstract
- In many regions and at the planetary scale, human pressures on the environment exceed levels that natural systems can sustain. These pressures are caused by networks of human activities, which often extend across countries and continents due to global trade. This has led to an increasing requirement for methods that enable absolute environmental sustainability assessment (AESA) of anthropogenic systems and which have a basis in life cycle assessment (LCA). Such methods enable the comparison of environmental impacts of products, companies, nations, etc, with an assigned share of environmental carrying capacity for various impact categories. This study is the first systematic review of LCA-based AESA methods and their applications. After developing a framework for LCA-based AESA methods, we identified 45 relevant studies through an initial survey, database searches and citation analysis. We characterized these studies according to their intended application, impact categories, basis of carrying capacity estimates, spatial differentiation of environmental model and principles for assigning carrying capacity. We then characterized all method applications and synthesized their results. Based on this assessment, we present recommendations to practitioners on the selection and use of existing LCA-based AESA methods, as well as ways to perform assessments and communicate results to decision-makers. Furthermore, we identify future research priorities intended to extend coverage of all components of the proposed method framework, improve modeling and increase the applicability of methods. © 2020 The Author(s).

Establishing common primary data for environmental overview of product life cycles. Users, perspectives, methods, data and information systems
- 2005
-
Reports (other academic/artistic)abstract
- This report describes how information about the environmental performance of products over their life cycles can be accessed anywhere and by any stakeholder throughout the product life cycle. Particular consideration has been given to different ways of performing a life cycle assessment (LCA). The report covers different users of environmental product information, the various methods and tools used to produce and disseminate that information, and the primary data needed for those methods and tools. The report also outlines an information system organisation for potential use as a cooperative approach to supporting stakeholders of product life cycles with environmental information. Chapter 2 contains a comprehensive (albeit not exhaustive) list of perspectives from which a stakeholder may environmentally view and assess products. A number of examples are given to describe reasons people have in practice for applying each perspective. The intention is to ensure that users find the methods and tools in chapter 3 to be truly relevant. Chapter 3 lists and presents methods and tools for assessing environmental performance, for acquiring information about environmental impacts, and for providing information on environmental properties of products. Particular emphasis is placed on the different types of LCA that have been identified, how they differ, how to use them, and their differing data requirements. Chapter 4 lists and presents the data and information that are used or produced by the methods and tools described in Chapter 3. This chapter includes discussion of data availability, data quality issues and data formatting. Chapter 5 proposes an information system organisation and design taking into account all perspectives and practical needs as described in Chapter 2, as well as all information and data issues described in Chapter 4. Particular attention is paid to the need for compatibility with existing systems, the technical and economic feasibility of building small systems instead of large ones, and the necessity of a short payback time for all investments, particularly those in the private sector. In chapter 6 the authors present outline recommendations for further work.

Toward Harmonizing Ecotoxicity Characterization in Life Cycle Impact Assessment
- 2018
-
In: Environmental Toxicology and Chemistry. - : Wiley. - 0730-7268 .- 1552-8618. ; 37:12, s. 2955-2971

Journal article (peer-reviewed)abstract
- Ecosystem quality is an important area of protection in life cycle impact assessment (LCIA). Chemical pollution has adverse impacts on ecosystems on a global scale. To improve methods for assessing ecosystem impacts, the Life Cycle Initiative hosted by the United Nations Environment Programme established a task force to evaluate the state-of-the-science in modeling chemical exposure of organisms and the resulting ecotoxicological effects for use in LCIA. The outcome of the task force work will be global guidance and harmonization by recommending changes to the existing practice of exposure and effect modeling in ecotoxicity characterization. These changes will reflect the current science and ensure the stability of recommended practice. Recommendations must work within the needs of LCIA in terms of 1) operating on information from any inventory reporting chemical emissions with limited spatiotemporal information, 2) applying best estimates rather than conservative assumptions to ensure unbiased comparison with results for other impact categories, and 3) yielding results that are additive across substances and life cycle stages and that will allow a quantitative expression of damage to the exposed ecosystem. We describe the current framework and discuss research questions identified in a roadmap. Primary research questions relate to the approach toward ecotoxicological effect assessment, the need to clarify the method's scope and interpretation of its results, the need to consider additional environmental compartments and impact pathways, and the relevance of effect metrics other than the currently applied geometric mean of toxicity effect data across species. Because they often dominate ecotoxicity results in LCIA, we give metals a special focus, including consideration of their possible essentiality and changes in environmental bioavailability. We conclude with a summary of key questions along with preliminary recommendations to address them as well as open questions that require additional research efforts.

Reports (other academic/artistic)abstract
- Hållbar utveckling innefattar såväl social, ekonomisk som miljömässig hållbar utveckling.I Miljöhandboken kommer dessa tre aspekter av hållbar utveckling att behandlas,dock ligger störst fokus på miljöaspekterna.Miljöhandboken ska hjälpa upphandlare att ställa relevanta miljökrav vid upphandlingoch är ett komplement till exempelvis Konkurrensverkets (f.d. Miljöstyrningsrådets)upphandlingskriterier och ska bidra med fakta kring hur miljökrav kan ställas.Miljökrav vid upphandling kan innefatta bl. a. energianvändning, livslängd, skadligaämnen, strålning, återvinning och miljöledningssystem. Kravens betydelse påverkasbl. a. av upphandlingens omfattning och miljömognaden inom produktsegmentet. Imiljöhandboken presenteras inga specifika kriterier eller gränsvärden för olika miljöaspekter,i stället ges länkar till exempelvis lagstiftning, myndigheter och miljömärkningar.Detta för att kriterier och gränsvärden uppdateras kontinuerligt som en följdav teknikutveckling men också för att den samlade kunskapen om vad som är miljöproblemständigt växer och kan ge upphov till nya kriterier och gränsvärden. Tyngdpunkteni denna handbok ligger på miljöpåverkan ur ett livscykelperspektiv, vilket innebäratt hänsyn tas till miljöpåverkan från utvinning av råmaterial till resthantering aven produkt.

231Pa and Th isotopes as tracers of deep water ventilation and scavenging in the Mediterranean Sea
- 2017
-
Licentiate thesis (other academic/artistic)abstract
- The naturally occurring isotopes 231Pa and 230Th are used as tracers of marine biogeochemical processes. They are both produced from the radioactive decay of their uniformly distributed uranium parents (235U and 234U) in seawater. After production, 231Pa and 230Th are removed by adsorption onto settling particles (scavenging) and subsequently buried in marine sediments. 230Th is more particle reactive compared to 231Pa. Consequently, 230Th will be removed from the open ocean by adsorption onto settling particles, while 231Pa tend to be laterally transported by currents and removed by scavenging in areas of high particle flux (e.g. ocean margins). The primordial 232Th indicates lithogenic supply via rivers and resuspension of sediments, which provides additional information about processes involved in the cycling of particle reactive elements in the ocean. The preferential deposition of particle reactive elements at ocean margins (boundary scavenging) has important implications for our understanding of the distribution and dispersion of micronutrients (e.g. iron) and pollutants in the ocean. It is therefore valuable to understand the nature of boundary scavenging processes in order to evaluate the relative contribution of circulation and scavenging behaviors.The major characteristics of thermohaline circulation in the Mediterranean are well known and have been studied for decades. This sea is an almost land-locked area, where limited water-exchange with the Atlantic Ocean only occurs through the Strait of Gibraltar. Therefore, this marginal sea is often referred to as a “miniature ocean” suitable as a “laboratory” for marine environmental research. In this licentiate thesis, distributions of 231Pa, 230Th and 232Th in seawater and marine particles collected during the GEOTRACES MedSeA-GA04-S cruise in 2013 are presented. Observed nuclide distributions indicate the impact of deep water formation processes, where observed differences can be linked to the type of deep water formation process that occurs in respective basin. Essentially all in-situ produced 230Th is buried in Mediterranean Sea sediments. Despite lower affinity of 231Pa for marine particles, most 231Pa is also scavenged and deposited in Mediterranean Sea sediments. The efficient scavenging of 231Pa produces a relatively low fractionation between 231Pa and 230Th in terms of the fractionation factor FTh/Pa. This licentiate thesis presents a summary of the methods used for the analysis of 231Pa and Th-isotopes with details on the exchange chromatography method and the treatment of mass spectrometric data. The study of 231Pa, 230Th and 232Th in the Mediterranean Sea has important implications for our understanding of processes that control their water column distributions and how their behavior can be utilized to trace chemical flux in modern and past ocean environments.
