Depolymerization and defunctionalization methods for existing chemicals that can allow circularity, especially for plastics; Design of circular systems with consideration of human health and ecotoxicity, ideally via rational design of benign commodity chemicals; Systematic application of life-cycle analysis, or thinking, and process metrics in developing new manufacturing/synthetic routes; Implementation

Though health disparities persist in most countries, many people living in developed regions have taken for granted the ability to control disease outbreaks, access to safe food, clean water, and healthy homes, and reliable sanitation. This consideration combined with fewer severe pandemics in recent years has contributed to reduced investments in public health systems. This pattern has resulted in

It has come to our attention that our Global Perspective (https://pubs.acs.org/doi/10.1021/acs.estlett.0c00844) contains several numerical errors. We note that these errors do not affect the overall findings and conclusions of our Global Perspective. In the first paragraph of the Water Use section, our comparison of water use from cannabis versus from total crop irrigation cited estimates from Butsic

A recent Global Perspective by Wartenberg et al. in Environmental Science & Technology Letters sheds much-needed light on the complex environmental impacts of cannabis cultivation.(1) Among the pathways identified by their ambitious review—land cover change, water use, pesticide use, energy use, air pollution, and water pollution—energy use may prove to be the most significant. Cannabis factory farming

In our Global Perspective, Cannabis and the Environment: What Science Tells Us and What We Still Need to Know (https://pubs.acs.org/doi/10.1021/acs.estlett.0c00844), we summarized existing scientific literature around cannabis and the environment. Our study was narrow in scope, with one exception; we reported only results that were peer reviewed and provided empirical evidence on environmental impacts

You only find what you are looking for has been a common principle within environment and health research and diagnostic activities. We routinely employ indicator approaches, for example, during surveillance of contaminants in air, water, soil, and food. We measure biomarkers to define health status in human populations and the integrity of aquatic and terrestrial ecosystems. This indicator strategy

The study of Xiao et al.(1) deals with the thermal stability of perfluoroalkyl substances (PFAS), in particular with the decomposition pathways of PFAS during thermal reactivation of spent granular activated carbon (GAC). The study provides valuable insights into the behavior of perfluorinated carboxylic acids (PFCAs) and sulfonic acids (PFSAs). It shows clearly that, contrary to common belief, PFCAs

Per- and perfluoroalkyl substances (PFAS) used as surface-active agents in nonstick cookware and firefighting foams have generally been assumed to be thermally stable. However, our results published in Environmental Science& Technology Letters showed that thermal decomposition of certain legacy PFAS compounds such as perfluorooctanoic acid (PFOA) can occur at temperatures as low as 150 °C.(1) In addition

Martin Luther King Jr. once famously said, “Life’s most persistent and urgent question is ‘What are you doing for others?’” Service takes many forms. Many of us serve in some capacity within our local community. We give our professional time in diverse ways, from serving on committees of societies to contributing to editorial boards of refereed journals. Each time we review a proposal or a manuscript
