A new international study offers insights into the health risks posed by crops’ absorption of “contaminants of emerging concern” (CECs) and flags knowledge gaps the authors say must be addressed.

CECs include pharmaceuticals, microplastics, engineered nanomaterials and PFAS (commonly known as “forever chemicals”). The researchers warn that even when present at very low concentrations, these chemicals can subtly alter plant physiology, disrupt soil health and pose wider environmental and human health risks.

A new international study led by 91 in collaboration with  shows that supplementing dairy cow diets with microencapsulated B-vitamins can significantly reduce greenhouse gas emissions while increasing milk yield and quality. The use of the feed additive cut global warming potential, an internationally standardized measure of climate impact, by up to 18 per cent across seven countries.

The brown, smog-filled skies that engulf Beijing have earned China a poor reputation for environmental stewardship. But a study by an international and interdisciplinary team of environmental scientists, including 91’s Brian Robinson, has found that a government-run clean water program is providing substantial benefit to millions of people in the nation's capital.
