The unsafe contaminant levels could not be attributed to differences in regional geology, water source, or community size. Researchers suggest they are due to a failure of regulatory policy.
A quarter of 258 observed rivers had unsafe levels of at least one drug. The findings raise concerns about Earth’s aquatic life and the global threat of antimicrobial resistance.
Use of deicing agents may sometimes raise sodium levels in drinking water beyond healthy limits for people on salt-restricted diets.
City communities may need to consider whether water absorption or cooling benefits are more important when designing urban greening.
Although causality has yet to be established, an Italian case study found that an increase in annual average exposure to PM2.5 was associated with a jump in the rate of COVID-19.
After a flood, most people rely on officials to test public water sources. Private well owners are on their own, with little data to guide testing and treatment. New research seeks to change that.
A study of 369 lakes across the Midwest finds that many of them, especially those close to agriculture, have high concentrations of harmful algal bloom-causing cyanobacteria.
En un nuevo estudio, investigadores aplicaron un modelo global del sistema Tierra para estimar los impactos de las reducciones de emisiones por sector.
Deforestation in the Amazon has dropped since the early 2000s, but it is slowly climbing again. A new study shows the impact of that climb on public health—and how much worse conditions could be.
