    Episode 14: Chemical Stripes – Visualizing Chemical Trends of the Past Influencing Today - with Dagny Aurich and Emma Schymanski

    Live from SETAC Europe 2023 - Raoul Wolf hosts a series of ZeroPM podcasts. In this episode he interviews Dagny Aurich and Emma Schymanski from the Univesity of Luxembourg about how the "climate stripes" data visualisation approach for climate change was adapted to "chemical stripes" to show the increasing ubiquity of persistent compounds in society and the enviornment. The number of chemicals threatening global health is rising rapidly, with increasing numbers of persistent compounds accumulating in our environment. There are alarming signals that elimination of existing and prevention of further contamination can no longer be delayed. Communicating this need for action to the scientific and non-scientific community in an understandable way poses a challenge for many researchers. This work shows the possibility to use chemical stripes to help communicate this message, modifying the existing graphics of the climate stripes - showing the trend of global warming - and applying it to the chemical space. Specific persistent organic pollutants (POPs) including per- and polyfluoroalkyl substances (PFAS), triazines and triazoles were selected based on their presence in regulatory lists, such as the Stockholm Convention. With the use of patent data for those compounds coming from the World Intellectual Property Organization (WIPO) and the comparison to the rise of overall chemical numbers registered in databases like the Chemical Abstract Service (CAS) registry, a definite trend can be seen: Patent and overall chemical numbers are on the rise and regulations do not stop this trend. Often the drafting, discussion, and adoption of legislation takes decades, even when there is need for quick action. The minimalistic but intuitive visualization of the chemical stripes helps communicate this information by indicating the evolving chemical numbers in traffic-light colours. The chemical and historical data presented, using the model of stripes, will be accompanied with open-source code (in progress) for others to generate their own stripes for a given set of chemicals. The colour scheme raises awareness of the "red" state we face today, with environmental pollution impacting our health and the ecosystems we live in. All substance classes investigated so far revealed the same pattern. Overall, the aim of these graphics is to emphasize the urgent need for elimination and prevention of persistent chemicals by illustrating the exponential growth of patent and chemical numbers over time, in the hope that this will help with the identification and prioritization of harmful substance classes and to help stimulate further action, without decades of delay.

    Episode 13: Need information on transformation products? There's an app for that! - with Emma Palm

    Live from SETAC Europe 2023 - Raoul Wolf hosts a series of ZeroPM podcasts. In this episode he interviews Emma Palm (Univesity of Luxembourg) about an app she developed to curate transformation product results, shiny TPs! An important consideration for understanding the hazards posed from different compounds is the transformation products (TPs) they form once they enter the environment. Unfortunately, there is much less information available for TPs than their parent compounds, while most of the information is text based in journal articles and databases. This makes it difficult to access and include into identification workflows based on high resolution mass spectrometry (HR-MS) and other analyses. One such database with text-based TP information is PubChem, which contains a lot of TP information, especially in the “Metabolism and Metabolites” section. In addition, PubChem runs a text mining software (LeadMine), which identifies chemical names in the text-based sections of the database. To better utilize this information, we have built a shiny app which will allow users to go through the text mined information in the Hazardous substance databank (HSDB) dataset to identify which of the extracted chemical names are TPs. After downloading the entire HSDB dataset and filtering based on the precursor compounds of interest, the app will display the structure of the precursor and the potential TP extracted via text mining, together with the HSDB text snippets to allow the user to identify whether the extracted structure is indeed a TP of the precursor. The information can then be saved in a table and downloaded for further analysis, or central upload as formal transformation reactions. In addition, the user has the option of saving the chemical names of TPs not identified by the text mining software together with their SMILES, to fill database gaps. The app has so far been applied to compounds from several datasets (28 from the NORMAN-SLE and 8 from the PubChem PFAS Tree, as well as 33 PBT compounds on the SIN-list). Of the 366 chemicals identified by the text mining software, 60 were new reactions that were not already available in the transformation products dataset in PubChem, the majority of which were found among the NORMAN and PBT compounds. Among these reactions were transformation products of azo dyes such as benzidine which has carcinogenic properties. In addition, some persistent substructures were identified in the TPs. This shows promise for expanding the current TP datasets available in databases such as PubChem as well as for improving TP suspect lists and furthering the understanding of the fate of environmental contaminants.

    Episode 12: Approaching variable data when assessing substance mobility - with Sivani Baskaran

    Live from SETAC Europe 2023 - Raoul Wolf hosts a series of ZeroPM podcasts. In this episode he interviews Sivani Baskaran (Norwegian Geotechnical Institute) about the how to assess mobility in relation to the new chemical hazard classes PMT and vPvM. Chemical hazard and risk assessments often use physical-chemical properties to categorize and identify chemicals of concerns. Recently, the European Commission introduced a draft revision of the classification, labelling and packaging (CLP) legislation that contained new chemical hazard categories, including persistent, mobile, and toxic (PMT) and very persistent and very mobile (vPvM) substances. Persistence is derived from the simulated half-life of a chemical in different systems (aquatic, soil, and sedimentary), depending on the compartment and degree of persistence evaluated, while mobility is determined based on the logarithmic organic carbon–water partition ratios (log Koc). But what is to be done when the log Koc data is either variable or uncertain? Sivani presents a way forward using a Bayesian approach.

    Episode 11: The Implementation of the Essential-Use concept in the REACH regulation - with Romain Figuière

    Live from SETAC 2023 - Raoul Wolf hosts a series of ZeroPM podcasts. In this episode he interviews Romain Figuière (Stockholm University) about the implementation of the Essential-Use concept in the REACH regulation. With ZeroPM colleagues, they approach this using "intentionally added microplastics" as a case study, by considering whether in products that #microplastics were essentially added to were essential for their uses, according to the current definition of the Essential-Use concept.

    Episode 9: Risk should not be made complicated when the hazard is clear - with Hans Peter Arp

    Live from SETAC 2023 - Raoul Wolf hosts a series of ZeroPM podcasts. In this episode he interviews Hans Peter Arp about his poster " Risk should not be made complicated when the hazards and exposure are clear", which can be found here. Different stakeholders will approach scientific uncertainty differently. Scientists are often driven to reduce uncertainty; regulators are driven to act on uncertainty (e.g. by invoking the precautionary principle), and those that are responsible for causing the environmental stress often seek to use scientific uncertainty as basis for inaction or deniability. To cut through these different viewpoints, the tool developed by William of Ockham (1287-1347), referred to as Ockham's razor, can be useful for governance. Ockham's razor states that "Entities are not to be multiplied without necessity", meaning in practice for this context that if adding new variables/complexities does not lower the overall uncertainty or picture of a sustainability assessment, then they should not be added, as they will only make governance more complex, and less transparent. When it preventing harmful chemicals from entering the environment, this has an impact on the role of risk perception and communication. In many cases, the hazards and risk of exposure are clear enough, from the perspective of some stakeholders, to prevent a substance from allowing a harmful chemical to be produced for a certain use. However, those who can profit from such substances, either as a producer or a consumer, may be drawn into the discussion of uncertainty to keep questioning the risk models, as a strategy to keep allowing the harmful substances in the environment.  To resolve diverse attitudes towards uncertainty, different stakeholders should be guided towards focusing on simple solutions with few variables, clear targets, that lay frank the societal winners and losers. Transparency is a key aspect here, as simple models and open data make it easier to engage in this dialogue. There should also be a focus on benefits of simple, sustainable solutions. Society should use  carrots (not just  sticks) to innovate towards beneficial, simple solutions to prevent environmental stressors, rather than argue about where the complicated impact thresholds are.
