Columbia and UC Berkeley researchers report in Nature that microplastics spontaneously generate reactive oxygen species in the water around them. The finding offers a chemical route to the tissue damage associated with microplastics, though the authors hedge on harm to people.

Boiling hard tap water trapped up to 90% of added plastic particles in Chinese tests
Researchers in China removed up to 90% of added nano- and microplastics from tap water by boiling it and filtering the residue. Removal climbed with water hardness, and the plastic was spiked into the samples, so a kitchen result will depend on the local supply.

Murdoch review argues the enzymes to break down pollutants are already in the databases
Joseph Boctor of Murdoch University argues that machine learning should mine the millions of enzymes already in databases to break down pollutants. He frames it as a quicker response to contaminants that are already in the environment and causing harm.

California's Oct. 1 listing starts the legal process for regulating microplastics
California will add microplastics to its Candidate Chemicals List on Oct. 1, the step its toxics regulator must take before targeting any product. The listing starts a formal process of public comment and review while talks on a global plastics treaty remain deadlocked.

Plastic already at sea keeps microplastics building even if new inputs end by 2050, model finds
Researchers modelling the G20's Osaka Blue Ocean goal find halting new inputs by 2050 leaves microplastics at 58.4% of accumulated plastic without cleanup. Earlier cleanup of legacy debris leaves less behind but costs up to 3.4 billion euros a year, against 1.0 billion for a delayed start.

Hurricane Helene rained 18.8% of a year's microplastics onto one North Carolina station
Hurricane Helene's rain delivered 18.8% of a year's microplastic deposition at one North Carolina station, according to a new study. At two other sites it added under 5%, so how much one storm counts varies sharply from site to site.

Advertising exposure tracked bottled-water use in a 15,000-person survey recruited on social media
Concordia researchers surveyed more than 15,000 people across 81 countries and found convenience, absent public taps and ad exposure all associated with single-use bottles, even though three quarters of respondents believed those bottles shed microplastics.

Fourteen water samples put the Truckee's spring microplastic count ten times above fall
A DRI-led team compared microplastics in the Truckee River across two seasons and found spring concentrations near ten times the previous fall's, on fourteen grab samples taken above and below Reno.

Microplastics showed up in every one of nine sacred South African springs sampled
Counts ran from 5 to 48 particles per liter at springs in the Eastern Cape and KwaZulu-Natal. With no agreed safe level for freshwater, the researchers offer the figures as a baseline to track over time.

Empa measures 219 tonnes of microplastic falling on Switzerland below 2,000 metres each year
A year of monthly sampling at five sites puts about 219 tonnes of microplastic on Switzerland below 2,000 metres, with the four non-urban stations landing within about a third of one another.

Weighting microplastics by polymer type reorders which Brisbane creek ranks worst
A QUT sediment survey of three urban creeks found the heaviest particle load in Kedron Brook but the highest toxicity-weighted risk in Bulimba Creek, a split that follows from how the index is built as much as from what is in the mud.

A week of eating polystyrene foam lifted three detoxification genes in the wharf roach gut
Kyushu University fed shoreline isopods nothing but polystyrene board for a week and found the effect in their gut transcriptomes rather than in their survival, which puts real weight on the choice of control group.
