研究通过调查分析湖北省重要的水产养殖区——洪湖周边的鱼塘、河蟹塘和龙虾塘等三种淡水养殖池塘的水体和水产品微塑料污染特征,可以为评估该养殖区的微塑料生态风险和了解我国淡水养殖环境微塑料污染现状提供数据支撑。结果表明,三种养殖塘水体微塑料丰度在(296±140)—(992±558)items/m3。与国内外其他淡水养殖水体相比,该地养殖塘水体微塑料丰度处于中等水平。该地养殖池塘中超过一半的水产品受到了微塑料的污染,微塑料丰度为0—16 items/ind.。纤维状微塑料是水体和水产品主要的微塑料类型。相关性分析和微塑料群落相似度分析表明,水体微塑料污染特征并不是影响生物暴露微塑料的直接原因,同时生物微塑料污染水平也不受生物种类的影响。考虑到水产品安全与人类健康关系密切,建议加强对养殖环境和水产品中微塑料污染的关注。

Perovskites have attracted extensive attention as radiation detection material due to their long carrier diffusion length and lifetime, high absorption coefficient, and flexible manufacturing process. Compared with polycrystalline structures, single crystal perovskites improve the performance of optoelectronic devices due to their low defect state density, better photoelectric characteristics, and chemical ***, we review the recent progress of single crystal perovskite X-ray detectors. First, we briefly introduced the basic concepts, detection mechanisms, figure of merits of perovskite X-ray detectors, and the preparation methods of single crystal perovskites. Then, we summarized the significant advancements in single crystal perovskite X-ray detectors in recent times. Finally, we discussed the critical challenges and some practicable solutions for developing high-performance X-ray detectors.
