Researchers found that the inclusion of cigarette butts in nests led to significantly elevated hemoglobin and red blood cell concentration, indicating improved physiological condition.

We want an end to the use of herbicides in our creeks. This idea that we're just going to spray, hose down these creeks and leave them dead is unacceptable. Linas and other residents have filed requests for records detailing the chemicals the county uses to control vegetation in the waterways, such as glyphosate, triclopyr and imazapyr.

Glyphosate is one of the most commonly used methods of handling weeds on farms and elsewhere. It is a key part of modern agriculture, to the point that imagining a food system that operates without it is incredibly challenging. Yet, glyphosate is also the subject of much debate.

Exposure to a fungicide induced changes to gene expression in rats that persisted for at least 20 generations. It also increased the chance of offspring developing kidney disease, obesity or experiencing complications when giving birth, according to the longest-running study of 'epigenetic' changes in mammals.

Many human activities - from improper disposal of waste to the degradation of car tyres - release small plastic particles, which have infiltrated the atmosphere, oceans and other ecosystems. These include nanoplastics - particles measuring less than 1 micrometre across - and microplastics, which range from 1 micrometre to around 5 millimetres. They've entered our bodies and brains, and scientists are still working to understand their effects on people's health.

New analysis has identified 25 chemicals linked to cancer that the Food and Drug Administration ( FDA) still allows in American food production. The findings come from scientists at the Environmental Defense Fund (EDF), a nonprofit environmental advocacy group, who determined that eight of the chemicals are classified as known human carcinogens and 17 are reasonably anticipated to be human carcinogens.
