Abstract：
We exposed adult individuals of the sentinel mangrove crab Minuca rapax to waterborne microplastics (MP; 53-63 μm polyethylene spheres) in a long-term experiment (56 days). Weassessed 1) MP effects on growth, survival, and food intake. and 2) the MP tissue acumulation and its reduction of body burden through feces and molting. MP exposure did not affect growth and survival. The hepatopancreas accumulated more MP than the gills and muscle. Most of the ingested MP particles were released in the feces and molts, indicating a rapid passage through the digestive tract. MP impaired food intake of M. rapax, with unknown consequences to the local populations. These results provide insights on MP translocation mechanisms, its elimination and toxicity associated with MP.
摘要：
在长期实验（56天）中，我们将前哨红树林蟹Minucarapax的成年个体暴露于水性微塑料（MP；53-63μm聚乙烯球）。我们评估了1)MP对生长的影响，生存,和食物摄入。和2）MP组织积害及其通过粪便和蜕皮减轻身体负担。MP暴露不影响生长和存活。肝胰腺积累的MP比g和肌肉多。大多数摄入的MP颗粒在粪便和蜕皮中释放，表明通过消化道的快速通道。MP损害了M.rapax的食物摄入量，对当地居民的影响未知。这些结果为MP易位机制提供了见解，其消除和毒性与MP有关。
