Antibiotic use in farming is now rampant. How meat is produced in China may mean the drugs you need here won’t work, says Prof Devi Sridhar, chair of global public health at the University of Edinburgh

"What we are seeing is compelling evidence that the climate crisis is not just an environmental emergency, it is potentially a neurological one."

A common pesticide can increase children’s risk of poor brain development and motor skills Kids exposed to chlorpyrifos while in the womb have altered neuron development and lower blood flow to their brains This can cause problems with motor skills among children

Some experts tee up public comment on EPA report calling fossil fuel concerns overblown, as others fast-track review

Almost 100 countries reject draft treaty as ‘unambitious’ and ‘inadequate’

Nonylphenol is a toxic xenobiotic compound classified as an endocrine disrupter capable of interfering with the hormonal system of numerous organisms. It originates principally from the degradation of nonylphenol ethoxylates which are widely used as industrial surfactants. Nonylphenol ethoxylates reach sewage treatment works in substantial quantities where they biodegrade into several by-products including nonylphenol. Due to its physical–chemical characteristics, such as low solubility and high hydrophobicity, nonylphenol accumulates in environmental compartments that are characterised by high organic content, typically sewage sludge and river sediments, where it persists.

Heat caused 2,300 deaths across 12 cities, of which 1,500 were down to climate crisis, scientists say

A chemical that takes thousands of years to break down is found in England's freshwater fish at 1,000 times above safe levels – and could end up on our dinner tables

Repeatedly mass infecting kids with COVID is not a public health strategy. It's a fast pass to declining population health

Repeated damage from extreme heat over time seems to be a leading factor causing kidneys to fail. Repeated damage from extreme heat over time seems to be a leading factor causing kidneys to fail.

A study led by the Joe C. Wen School of Population & Public Health at the University of California, Irvine has revealed possible links between exposure to per- and polyfluoroalkyl substances in drinking water and an increased risk of certain childhood cancers.

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.

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.

The exponential rise in microplastic pollution over the past 50 years may be reflected in increasing contamination in human brains, according to a new study. It found a rising trend in micro- and nanoplastics in brain tissue from dozens of postmortems carried out between 1997 and 2024. The researchers also found the tiny particles in liver and kidney samples.

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.

For hundreds of millions of people living in India and Pakistan the early arrival of summer heatwaves has become a terrifying reality that’s testing survivability limits and putting enormous strain on energy supplies, vital crops and livelihoods. Both countries experience heatwaves during the summer months of May and June, but this year’s heatwave season has arrived sooner than usual and is predicted to last longer too. Temperatures are expected to climb to dangerous levels in both countries this week.

Recent projections suggest that large geographical areas will soon experience heat and humidity exceeding limits for human thermoregulation. The survivability limits modeled in that research were based on laboratory studies suggesting that humans cannot effectively thermoregulate in wet bulb temperatures (Twb) above 26 to 31 °C, values considerably lower than the widely publicized theoretical threshold of 35 °C. The newly proposed empirical limits were derived from the Twb corresponding to the core temperature inflection point in participants exposed to stepped increases in air temperature or relative humidity in a climate-controlled chamber. Despite the increasing use of these thermal-step protocols, their validity has not been established. We used a humidity-step protocol to estimate the Twb threshold for core temperature inflection in 12 volunteers.

Pesticides affect a diverse range of non-target species and may be linked to global biodiversity loss. The magnitude of this hazard remains only partially understood. We present a synthesis of pesticide (insecticide, herbicide and fungicide) impacts on multiple non-target organisms across trophic levels based on 20,212 effect sizes from 1,705 studies. For non-target plants, animals (invertebrate and vertebrates) and microorganisms (bacteria and fungi), we show negative responses of the growth, reproduction, behaviour and other physiological biomarkers within terrestrial and aquatic systems. Pesticides formulated for specific taxa negatively affected non-target groups, e.g. insecticidal neonicotinoids affecting amphibians. Negative effects were more pronounced in temperate than tropical regions but were consistent between aquatic and terrestrial environments, even after correcting for field-realistic terrestrial and environmentally relevant exposure scenarios. Our results question the sustainability of current

Atrazine is an herbicide widely used on plantations worldwide. Experimental studies suggest that the herbicide impairs male reproductive function in mammals. This systematic review and meta-analysis aimed to evaluate the impact of atrazine exposure on the levels of hormones from the hypothalamic-pituitary-testicular axis using murine as the animal model. After an extensive literature search, we selected 25 articles for the systematic review.

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.
