According to a new study by the University of Exeter, tiny plastic particles contaminating the ocean not only enter the marine organisms orally, but also enter the body system through the sputum. Scientists have also discovered that when plastic particles are inhaled in this way, marine organisms need to spend six times longer than normal digestion time to get the plastic particles out of the body. Dr. Andrew Watts of the University of Exeter said: "Many studies on plastic particles have only considered the way in which plastic particles enter the animal. The results we just announced include other ways, such as ventilation. The crab has not been tested for experiments, but the results also apply to other crustacean mollusks and fish and those that use the same structure to ventilate the fish." From an ecological point of view, this is very important. If these plastic particles remain in the animal for a longer period of time, these plastic particles are likely to enter the top animal of the food chain. The researchers used fluorescently labeled polystyrene microspheres to show how the ingested plastic particles remained in the tissues of common coastal crabs. Multiphoton imaging showed that most of the microspheres were stuck in the hairy bristle structure of the crab. After being retained in the foregut.
