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.
Low-temperature CO2 hydrogenation might have sounded almost paradoxical until a recent study made it possible. Researchers have designed new catalysts that can transform the greenhouse gas into methanol at temperatures ranging from room temperature to 200° C, whereas most catalysts can operate only at or above 250° C. The research is published in the journal Nature Chemistry.
