The hydrodynamics and their evolution on the Upper Yangtze Block during the Ordovician-Silurian transition period remain unclear. The present study is an assessment of how regional and global events may have influenced the hydrodynamic evolution based on a planar lamination investigation of the shales from the Upper Yangtze Block. Analyses of large thin sections and argon-ion polished thin sections using field emission-scanning electron microscopy(FE-SEM) showed that there are four types of planar lamination, namely, silty graded planar lamination(SGPL), silt-clay graded planar lamination(SCGPL), silt-clay interlaminated planar lamination(SCIPL), and paper-like planar lamination(PPL). SGPL is formed by turbidity current with a flow speed less than 15 cm/s. SCGPL is formed by turbidity currents with a flow speed less than 15 cm/s for normal grading type and 15-25 cm/s for alternating grading type. SCIPL has a continuum of sparsely spaced type, closely spaced type, and alternating type, which is formed by bottom current with an increasing flow speed from 15 to 25 cm/s to above 25 cm/s. PPL can be divided into normal grading and composite grading types. The former is formed by vertical settling, while the latter is formed by bottom current with a flow speed of 5-15 cm/s. Vertically, types of planar lamination varied from SGPL to PPL and then SCIPL manifesting the waxing and waning of flow speed with a positive excursion at graptolite biozone Metabolograptus extraordinarius(WF4) and a negative excursion at graptolite biozone Persculptograptus persculptus(LM1). The sudden decrease in flow speed across Linxiang and graptolite biozone Paraorthograptus pacificus(WF3) and the subsequent progressive increase from graptolite biozone Akidograptus ascensus(LM2)to graptolite biozone Demirastrites triangulatus(LM6) and to graptolite biozone Stimulograptus sedgwickii(LM8) during deposition of the Ordovician-Silurian transition succession on the Upper Yangtze Block were linked to th

紫外吸收剂(UVAs)是个人护理产品和工业产品中常见的一类添加剂.因其伪持久性、生物累积性和毒性,UVAs的环境污染和风险已引起人们的广泛关注,然而目前对城市水环境中UVAs污染特征和生态风险的了解仍然较少.为探究水环境中UVAs的赋存、组成和空间分布特征,分析了珠江广州段40个水样(包括水相和悬浮颗粒相)中常见UVAs的浓度,并利用风险商评估其潜在水生态风险.结果表明,珠江广州段水相和颗粒相中UVAs被广泛检出,两相中总浓度(∑_(8)UVA,范围及平均值±标准差,ng·L^(-1))分别为6.52~85.8(2.80±6.34)和5.69~461(6.57±34.1).UVAs在水相中的占比范围为16%~99%,疏水性强的化合物更易于分配在颗粒相.珠江广州段下游水体中UVAs的浓度高于上游,娱乐场所、工业区和污水处理厂附近水体中UVAs检出浓度较高.个人护理品添加剂2-氰基-3,3-二苯基丙烯酸-2-乙基己酯(OCR)在水相和颗粒相中均是最主要的UVA,检出浓度分别占总浓度的50%和60%.风险商的结果显示珠江广州段水体中目标UVAs的水生态风险处于低到中等水平,亟需关注其长期暴露风险.
