Forskare har identifierat utbredda silikonföroreningar i atmosfären globalt

Forskare har upptäckt oväntat höga nivåer av metylsiloxaner, en klass av silikonföreningar, i luftprover från städer, landsbygd och skogar runt om i världen. Studien kopplar en stor del av föroreningen till fordonsutsläpp från tillsatser i motorolja. Experter varnar för att den dagliga mänskliga inandningen av dessa ämnen kan överstiga exponeringen för andra kända föroreningar som PFAS.

Resultaten kommer från ett team vid Utrechts universitet och universitetet i Groningen. De mätte föreningarna på platser i Nederländerna, Litauen och Brasilien. Koncentrationerna nådde 98 nanogram per kubikmeter i São Paulo och sjönk till 0,9 nanogram per kubikmeter i en litauisk skog. Föroreningarna stod för 2 till 4,3 procent av de totala organiska aerosolerna i de testade proverna.

Study maps pesticide mixtures in Peru and finds higher cancer risk in high-exposure areas

27 april 2026 Rapporterad av AI Bild genererad av AI Faktagranskad

A study published in *Nature Health* reports a statistical link between environmental exposure to mixtures of agricultural pesticides and higher cancer risk in Peru. Using modeled pesticide dispersion from 2014 to 2019 and cancer registry data from 2007 to 2020 covering more than 150,000 cases, researchers found that people living in high-exposure areas faced, on average, about a 150% higher likelihood of cancer, with Indigenous and rural farming communities among those most exposed.

Land sources emit over 20 times more airborne microplastics than oceans

Researchers at the University of Vienna have determined that land releases more than 20 times as many microplastic particles into the atmosphere as the oceans, challenging prior assumptions. Their study, published in Nature, used global measurements to correct overestimated emission models. The findings highlight land as the dominant source, though uncertainties persist.

University of Michigan study finds lab gloves skew microplastics data

30 mars 2026 Rapporterad av AI

Researchers at the University of Michigan have discovered that common nitrile and latex lab gloves release particles resembling microplastics, potentially inflating pollution estimates. The study, led by Madeline Clough and Anne McNeil, traced contamination to stearates in the gloves during sample preparation. Switching to cleanroom gloves could reduce false positives significantly.

Pilot study finds microplastics in most prostate tumor samples, with higher levels than nearby benign tissue

25 februari 2026 Rapporterad av AI Faktagranskad

Researchers at NYU Langone Health reported detecting microplastics in prostate tumor tissue from a small group of men undergoing prostate removal surgery, with average concentrations about 2.5 times higher in tumor samples than in nearby noncancerous tissue. The team says the findings, scheduled for presentation Feb. 26, 2026, at the American Society of Clinical Oncology’s Genitourinary Cancers Symposium, add early evidence that microplastic exposure could be relevant to prostate cancer but do not establish cause and effect.

Is Delhi haze caused by Iran's petrol rain? Expert answers

In recent days, rumours circulating online have suggested that the haze over Delhi could be linked to smoke or chemical fallout from refinery strikes in Iran, even claiming that 'petrol rain' in the region was responsible for the unusual atmospheric conditions. An expert provides answers to these claims.
