Researchers have detected multiple antibiotics in Brazil's Piracicaba River, accumulating in water, sediment, and fish, especially in the dry season. A banned drug, chloramphenicol, was found in lambari fish sold for consumption. Experiments with the aquatic plant Salvinia auriculata showed it can remove some antibiotics but may alter fish exposure.

Pemex reported 85% progress in cleaning hydrocarbon-contaminated beaches in Veracruz and Tabasco, with 91 tons of waste collected. Cleanup brigades started work on March 5 in Veracruz and expanded to several areas. Federal authorities are coordinating the environmental contingency response.

Scientists have confirmed that Belgica antarctica, the southernmost insect on Earth, is ingesting microplastics in the wild. Lab experiments reveal that while the insect's larvae survive short-term exposure, higher plastic levels lead to reduced fat reserves. The findings highlight the global reach of plastic pollution, even in isolated Antarctica.

The Commission for the Megalopolis Environment (CAMe) reported that Phase 1 air quality contingency remains in effect this Friday, February 13, in the Metropolitan Zone of the Valley of Mexico due to poor air quality. Ozone buildup is expected with temperatures up to 27 degrees Celsius, keeping the Double No Drive program active. Authorities recommend avoiding outdoor activities between 1:00 p.m. and 7:00 p.m. to protect health.

In 2026, ocean plastic pollution continues to escalate, with estimates of 19 to 23 million tons entering aquatic ecosystems annually. Despite growing awareness, the Great Pacific Garbage Patch spans an area twice the size of Texas, holding 1.8 trillion plastic pieces. Initiatives like Plastic Bank and Delterra offer hope, but the UN Global Plastics Treaty remains unresolved after failed negotiations.

Trifluoroacetic acid (TFA), a persistent pollutant known as a forever chemical, has more than tripled in the global environment over the past two decades, largely due to refrigerants that protect the ozone layer. While current levels remain below known safe thresholds, the chemical's long-term accumulation raises concerns for human health and aquatic life. Researchers urge scrutiny of newer replacements to avoid unintended environmental consequences.
