Carbamates are valuable compounds, albeit some of them can be hazardous. They may bring life and hope, as seen in relevant drugs and in agrochemicals that improve crop productivity through pest control. However, excessive use poses environmental and health risks. The inclusion of some carbamates in the Chemical Weapons Convention reminds of their toxicity and potential danger. Details are presented in the Review Carbamates: Are they "Good" or "Bad Guys"? by Diego G. R. Voris, Samir F. A. Cavalcante, Caio V. N. Borges and Antonio L. S. Lima on e-20240058.

In this short review, we present how carbamates can be seen as "good guys" by their use in medicine (hope), or "bad guys", due to their misuse in pesticides and as chemical weapons (death).

The study investigated the distribution of arsenic and metals in a Brazilian tropical reservoir over time. Elevated element concentrations were found in specific water and sediment zones. The sediment core dated back to 1940 and showed increasing element concentrations, emphasizing the need for ongoing monitoring.
