6PPD-quinone in water from the San Francisco-San Joaquin Delta, California, 2018-2024
The Sacramento-San Joaquin Delta (Delta) is an expansive river delta supplying a large portion of California’s fresh water for agriculture and residential use, and it is also an area of critical habitat for numerous state and federally listed species of concern. In many locations, urban stormwater flows directly into the Delta. 6PPD-quinone (6PPD-Q), an ozonation byproduct of a tire...
Genome sequences of toxigenic cyanobacteria from a bloom in Lake Mattamuskeet, North Carolina (United States)
Lake Mattamuskeet, the largest lake in North Carolina, USA, has undergone decades-long eutrophication causing reduced water quality and promoting cyanobacterial blooms that may produce toxins. It is therefore necessary to evaluate the cyanobacterial diversity of the lake and their toxigenic potential. We present draft genomes of Microcystis, Pelatocladus, Raphidiopsis, and Umezakia...
Before the fire: Predicting burn severity and potential post-fire debris-flow hazards to Colorado River Cutthroat Trout (Oncorhynchus clarkii pleuriticus) conservation populations
BackgroundColorado River Cutthroat Trout (CRCT; Oncorhynchus clarkii pleuriticus) conservation populations may be at risk from wildfire and post-fire debris flows hazards.AimTo predict burn severity and potential post-fire debris flow hazard classifications to CRCT conservation populations before wildfires occur.MethodsWe used remote sensing, spatial analyses, and machine learning to...

Decoding Harmful Algal Blooms: Unraveling the Mystery
Harmful algal blooms (HABs) are a significant environmental concern due to their potential effects on health, ecosystems, and economies. Algal toxins, which are toxic compounds produced by certain species of cyanobacteria and algae, are commonly linked to these blooms. It's important to note that algal toxins can still be present even when a bloom is not visible, highlighting the need for ongoing...

Understanding Algal Bloom Dynamics in Lake Okeechobee
The U.S. Geological Survey (USGS) is conducting studies to better understand algal bloom dynamics to enhance lake management. Recent research, in Lake Okeechobee, Florida, focused on phytoplankton community and abundance. Phytoplankton can be a potential driver of harmful algal blooms (HABs).
USGS Research on 6PPD-quinone: Where the Rubber Meets the Road
Stormwater and road runoff are recognized forms of pollution that can contain chemicals harmful to fish and other aquatic animals. This includes 6PPD-quinone, the oxidized form of the chemical compound 6PPD that is used to prevent tires from degrading and cracking, ensuring driver safety. As 6PPD-quinone sheds from tires during normal wear it can enter streams in stormwater runoff.
