The fish early life-stage (FELS) test guideline (OECD 210 or OCSPP 850.1400) is the most frequently used bioassay for predicting chronic fish toxicity and supporting aquatic ecological risk assessments around the world. For each chemical, the FELS test requires a minimum of 360 fish and 1 to 3 months from test initiation to termination. Although va...

Does the post-WWII burial at sea of chemical weapons still pose a human and environmental risk?
Article
The risks associated with occurrence of pharmaceuticals in water resources are mostly unknown. In the absence of extensive toxicological data, we scanned all the compounds observed in the environment for toxicological properties by (Quantitative) Structure Activity Relationship ((Q)SAR). The results of the probabilistic distribution of environmenta...
Article
Four different classes of environmental concern are quantitatively and qualitatively assessed for environmental hazards; antibiotics (n = 226), antineoplastics (n = 81), cardiovascular (n = 272), and sex hormones (n = 92). These along with an ECOSAR scan of all pharmaceuticals (n = 2848) were then classified according to the OECD aquatic toxicity c...
Article
Full-text available
The challenges faced by universities and private industry in estimating their emissions for decarbonisation are similar, but the task of linking emissions to university operations, namely procurement, is complex and time-consuming due to the wide range and types of purchases. Here, participatory action research is used to address these challenges,...
Article
Full-text available
Exposure to hazardous chemicals can cause adverse effects in humans and the environment. In response to a large number of chemicals potentially emitted to the environment and costly monitoring programmes, prioritisation schemes have been developed to identify candidate substances for further investigation, based on their hazard, exposure and enviro...

Armed conflicts have, in addition to severe impacts on human lives and infrastructure, also impacts on the environment, which needs to be assessed and documented. On September the 26th 2022, unknown perpetrators deliberately ruptured the two gas pipelines Nord Stream 1 and 2 with four coordinated explosions near a major chemical munition dump site...
Article
Full-text available
There has been a notable absence of procurement emissions in university GHG inventories, which act to inform universities of possible decarbonization pathways only partially. Guided by a methodological trade-offs consensus document presented by a consortium of Danish universities, this study estimates the 2021 emissions of Aarhus University, includ...

During the 20th century, thousands of tons of munitions containing organoarsenic chemical warfare agents (CWAs) were dumped into oceans, seas and inland waters around the world. As a result, organoarsenic CWAs continue to leak from corroding munitions into sediments and their environmental concentrations are expected to peak over the next few decad...
Article
Cationic polymer (CP) ecotoxicity is important to understand and investigate as they are widely used in industrial and consumer applications and have shown toxic effects in some aquatic organisms. CPs are identified as "polymers of concern" and are to be prioritized in upcoming regulatory reviews, (e.g., REACH). Algae have generally been found to b...

To remain relevant in the green transition, companies are beginning to voluntarily account for the exchange of emissions in their supply chain transactions and using the resulting greenhouse gas inventories for climate resilient decision support. Market advantages of sustainability and transparency see a shift from internal decision support tools t...
Article
Cationic polymers are considered by the scientific and regulatory communities as a group of greater interest amongst the polymers in commerce. As a category, relatively little hazard information is available in the public literature. Very few examples exist of published, high quality polymer characterization and quantification of exposure. In this...
Article
Polymers have historically been excluded from registration and evaluation under the European chemicals management program of REACH. Recently, interest has increased to include polymers. A tiered registration system has been envisioned and would begin with classes of polymers of higher interest based on certain properties. Cationic polymers are one...

Adaptation to climate change poses two recognized significant types of risks to the private sector; (1) physical risks and (2) transitional risks. As markets respond to climate-related policies and shifting demands from customers and investors, opportunities as well as risks are presented. A very recent and important policy development is the Europ...

Sea dumping of chemical warfare (CW) took place worldwide during the 20th century. Submerged CW included metal bombs and casings that have been exposed for 50–100 years of corrosion and are now known to be leaking. Therefore, the arsenic-based chemical warfare agents (CWAs), pose a potential threat to the marine ecosystems. The aim of this research...

Sulphur mustard (HD) was the most widely produced chemical warfare agent (CWA) in the history of chemical warfare (CW). Simultaneously, the loads of HD account as by far the largest fraction of the sea-dumped CW. Nowadays its presence in the marine ecosystems recognized as a serious threat for marine users and maritime industries. Although, during...
Chapter
Polymers are highly diverse and understudied materials from an environmental toxicity point of view. For the past decades, polymers have largely been out of scope regarding detailed safety assessment in most regulatory programs as they are assumed to not possess relevant toxicological properties due to their size. This regulatory exclusion is curre...

The letter to the editor strongly suggests that the Freeling et al. (2019) paper be recast in the light of a more holistic understanding of surfactant physicochemical properties, fate, exposure, QSARs, SSDs, model stream studies, and eco-epidemiological assessments. Once understood and incorporated, we are confident that the authors will reconsider...

Multiple modes of action (MOA) frameworks have been developed in aquatic ecotoxicology, mainly based on fish toxicity. These frameworks provide information on a key determinant of chemical toxicity, but the MOA categories and level of specificity remain unique to each of the classification schemes. This study aimed to develop a consensus MOA assign...
