Global Challenges: Opening up Chemistry, Pandemics, and Air Pollution

As the first half of 2022 comes to a close, it is an interesting time to reflect on some recent trends. In many ways, the world is “opening” up again, with many colleagues going to their first “in person” conferences since the start of the pandemic in early 2020. A significant leap forward for open chemistry was made in 2021, with the Chemical Abstracts Service (CAS) Registry embracing a hybrid model and releasing half a million chemicals as the CAS Common Chemistry set under an open license. (1)ACS Environmental Au continues to develop as one of the key gold open access journals for publishing work on environmental topics. (2) The European Union has just launched the €400 million European Partnership for the Assessment of Risks from Chemicals (PARC), with ∼200 partners (3) and a whole work package on FAIR (Findable, Accessible, Interoperable, Reusable) (4,5) and Open (6) data. While these trends are cause for optimism, the CAS Registry continues to climb toward the 200 million chemical mark (7) and many of us were blown away by the sheer immensity of the chemical pollution problem at recent meetings. Other colleagues, e.g., those affected by war, by lockdowns, or with insufficient funds, are unable to share in the “post-pandemic” reopening, conferences, and travel. Others cannot afford the costs associated with open access or still do not see the benefits of open science.
Why the focus on these disjoint subjects? Both chemical pollution and the COVID-19 pandemic are global challenges requiring global solutions, where failure to act comes with a high price. Landrigan et al. estimated that 9 million premature deaths (16% of the global total) were caused by pollution in 2015. (8) Worldwide deaths directly due to the COVID-19 pandemic are already over 6 million (9) (January 2020 to May 2022). While public awareness is high, individuals often feel powerless to tackle global challenges─yet the pandemic has proven that individual actions can make an incredible collective difference. The same applies to open data and the exchange of research results─the collective benefit from many individual contributions can be extraordinary.
