Toxic pollution from wildfires has infiltrated the homes of more than a billion people a year over the last two decades, according to new research. The climate crisis is driving up the risk of wildfires by increasing heatwaves and droughts, making the issue of wildfire smoke a “pressing global issue”, scientists said.

A microplastics and toxic chemicals expert says her family doesn't wear shoes at home. Microplastics from car tires and garbage, as well as street runoff, can be tracked indoors on shoes. The researcher thinks her kids' Japanese heritage helped them adopt the habit.

L’agence sanitaire a analysé 599 expositions et intoxications liées à 150 produits phytopharmaceutiques. Selon l’étude publiée lundi, les trois quarts d’entre elles étaient accidentelles, tandis que le quart restant « relevait de conduites suicidaires ».

Springtails illustrate in new research how global warning and antibiotic resistance creates synergistic effects: warming increases pesticide toxicity, triggering antibiotic resistance which spreads through horizontal gene transfer and predation.

Metals and metalloids are ubiquitous in soils, originating from bedrock and from human activities and infrastructure. These compounds can be toxic to humans and other organisms, and their soil distribution and concentrations at global scale are not well known. Hou et al. analyzed data from more than 1000 regional studies to identify areas of metal toxicity and explore drivers of these trends. They estimate that 14 to 17% of cropland exceeds agricultural thresholds for at least one toxic metal.

Microplastics have been found for the first time in human ovary follicular fluid, raising a new round of questions about the ubiquitous and toxic substances’ potential impact on women’s fertility. The new peer-reviewed research published in Ecotoxicology and Environmental Safety checked for microplastics in the follicular fluid of 18 women undergoing assisted reproductive treatment at a fertility clinic in Salerno, Italy, and detected them in 14.

The multibillion-dollar chemicals company 3M told customers its firefighting foams were harmless and biodegradable when it knew they contained toxic substances so persistent they are now known as “forever chemicals” and banned in many countries including the UK, newly uncovered documents show.

Une étude réalisée à l’aide d’une IA a analysé 180 goûts différents de cigarettes électroniques. Les résultats sont alarmants.

Le fentanyl et les autres opioïdes sont de plus en plus associés à des stimulants, en particulier la méthamphétamine. Une évolution qui met déjà en échec les traitements et les stratégies de lutte contre l’épidémie outre-Atlantique.

Comme dans le Sud-Ouest, des cas d’intoxications alimentaires ont été remontés aux autorités normandes, qui ont décidé d’une interdiction ce vendredi 29 décembre. Les symptômes sont ceux de «gastro-entérites aiguës».
