Environmental context. Tyre rubber particles, from both driving and reuse of tyre rubber, are pollutants that carry toxic chemicals into the environment. We investigated the long-term effects that these particles have on small aquatic organisms and found that they drastically reduce their ability to reproduce. Continued exposure of aquatic invertebrates to tyre-related pollutants, has the potential to affect the population by inhibiting reproduction into future generations.

Environmental context. Exploring the characterisation and sources of the chemical composition of fine particulate matter in the atmosphere is critical to human health. Dust, primarily from soil, is the main source of atmospheric fine particulate matter in Chengguan and Xigu Districts of Lanzhou City, Gansu Province, rather than other causes. This provides directions and ideas for future local ecological environment and pollution management. (Image credit: Qin Cui.)
