Microplastic ingestion was reported for common bottlenose dolphins () inhabiting Sarasota Bay, FL, USA, a community that also has prevalent exposure to plasticizers (i.e., phthalates) at concentrations higher than human reference populations.

Traditional approaches to carbon capture involve corrosive and energy-intensive processes such as liquid amine absorption. Although adsorptive separation has long been a promising alternative to traditional processes, up to this point there has been a lack of appropriate adsorbents capable of capturing CO whilst maintaining low regeneration energies.

Herein, we synthesized a new moisture-stable Zn-MOF, , , by utilizing a bent organic linker 4,4'-sulfonyldibenzoic acid (HSDB) containing a polar sulfone group (-SO) and a N, N-donor spacer () with a Brunauer-Emmett-Teller surface area of 216 m g. This material displays greater CO adsorption capacity over N and CH with high IAST selectivity, which is also validated by breakthrough experiments with longer breakthrough times for CO.

However, gas stream moisture can be detrimental to both adsorbent performance and hydrolytic stability. One of the most effective methods to solve this issue is to transform the adsorbent surface from hydrophilic to hydrophobic.
