Abstract
In the aquatic environment, pharmaceuticals and personal care products (PPCPs) detected in sediments are rising health concerns to human and aquatic ecosystem. The migration of PPCPs in the sediments poses a potential risk to surface water and groundwater environment. Insight on the spatial distribution and vertical profile of PPCPs in sediments at the regional scale is valuable for comprehensive prevention of PPCP risk. The Haihe River is one of the major water systems for the rapid development of urbanization, industrialization and agriculture in Northern China. The study aimed to characterize the occurrence, distribution and ecological risks of PPCPs in the sediments of the Haihe River, especially to investigate the vertical distribution of PPCPs using core sediments. High performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was used to analyze 24 selected PPCPs in sediment samples. In total, 11 PPCPs were detected, and the detected concentrations (0-1.26 ng g-1) were, lower than in other water bodies in literature (0-24.4 ng g-1). The sediments of the Haihe River located in the Tianjin downtown were most-severely polluted, with the highest cumulative concentration of PPCPs of 9.45 ng g-1, indicating the relatively high contribution of human consumption of PPCPs for the megacity. Spearman correlation analysis shows that both of the TOC contents and particle size distribution can influence the migration and deposition of PPCPs. The risk assessment results showed that the current level of PPCPs has no severe adverse effects on aquatic organisms in the Haihe River. However, special attention should be paid to the environmental risks caused by the migration of PPCPs with high loading and mobility (such as sulfamethoxazole).

Insights into the horizontal and vertical profiles of microplastics in a river emptying into the sea affected by intensive anthropogenic activities in Northern China.

Abstract
Studies focused only on surface water may underestimate microplastic abundance in aquatic environments. This was the first survey to investigate the vertical (surface, intermediate, and bottom waters) distribution and composition of microplastics (MPs) in the water columns and surface sediments collected from an urban seagoing river in northern China. Microplastic abundance in the water columns ranged from 5.6 to 31.4 items∙L-1 and from 2141 to 10,035 items∙kg-1 dry weight (dw) in the surface sediments. Polyethylene dominated throughout the water columns to the surface sediments, in which low- and high-density polyethylene (LDPE and HDPE) were dominant in the water columns and surface sediments, respectively. The dominant shape of MPs was fibers/lines in both the water column and the surface sediment samples. Different from the estimations, the average abundance of MPs in the surface and intermediate waters was significantly lower (p < 0.01) than that in the bottom water, which may be due to the resuspension of small-sized MPs in the bottom water. As the MPs size increased, their vertical distributions in the water columns were more affected by the water depth. The results showed that MPs were detained in the water columns of river system, and the high concentrations of MPs in the bottom water could not be neglected.
