An industrial park on the outskirts of Hanoi in northern Vietnam experienced a brief but intense rainstorm the previous night. The water level in the facility’s temporary wastewater storage pond rose rapidly, overflowing the embankment, and a large volume of accumulated industrial wastewater leaked out. Some of this untreated industrial wastewater—containing various chemical residues and…

A long-distance agricultural irrigation main pipeline in California’s San Joaquin Valley suddenly burst, causing large volumes of agricultural wastewater—contaminated with fertilizer residues—to flow through ditches into a tributary of the Sacramento River. Environmental sampling results show that nitrogen and phosphorus concentrations in the affected river section have risen sharply, posing risks of blue-green algae blooms…

The “Ross Fire” in northern Texas continues to spread rapidly. Fueled by extreme drought and strong winds, the fire has burned an area of approximately 202 square kilometers in just 24 hours, with only 5 percent of the fire contained. In 2026, the number of wildfires across the United States has already exceeded 50,000, breaking…

In a total of six regions—the northern and southern parts of Gyeonggi Province, Busan, Ulsan, and the northern and southern parts of Gyeongsang Province—ground-level ozone levels reached the “Poor” category, while air quality in the remaining areas was generally fair. Although PM2.5 levels were favorable, persistent high temperatures combined with intense sunlight triggered photochemical reactions…

Wildfires around Reno, Nevada, remain out of control. The blazes have caused injuries, prompted the emergency evacuation of large numbers of residents, and led to evacuation alerts for even more people. As a result of the disaster, widespread power outages and road closures have occurred in the area, and airport operations have been restricted. The…

Clark County, Nevada, has issued a dust pollution advisory. Due to downdrafts caused by severe thunderstorms in Arizona, large amounts of dust have been carried northward by strong winds, blanketing the entire Las Vegas Valley. This marks the second time this month that Las Vegas has experienced cross-border dust pollution. During the summer, severe convective…

A massive forest fire has erupted near the city of Kradovo in eastern Serbia. Fueled by strong winds and extremely dry vegetation, the fire spread rapidly within a few hours, with the burned area now exceeding 1,000 hectares. Meteorological authorities have issued a warning that a new round of extreme heat is about to hit…

At the Stora Enso paper mill in Imatra, eastern Finland, a byproduct storage tank exploded, causing approximately 50 cubic meters of tall oil (a byproduct of the pulp industry) to leak and spread. Some of the oil entered the Lake Sema watershed via the mill’s drainage system. Tall oil contains components such as resin acids…

Due to the combined effects of persistent high temperatures and agricultural nonpoint source pollution, the blue-green algae bloom in the western part of Lake Erie has expanded rapidly, covering an area of 812 square kilometers—the largest such bloom for this time of year in the past three years. Test results show that microcystin concentrations in…

A lightning strike hit an oil storage facility in Texas, causing two large crude oil storage tanks to catch fire and burn intensely. A column of black smoke rose dozens of meters into the air and was clearly visible from several kilometers away. Burning oil releases sulfur dioxide, nitrogen oxides, volatile organic compounds, and fine…
