AB  - Sediment samples were collected from 11 typical sites in Hengshui Lake separately 
      in August 2018 and March 2019. Characteristics and ecological risk assessment of 
      typical persistent organic pollutants (POPs), including polycyclic aromatic 
      hydrocarbons (PAHs), organochlorine pesticides (OCPs), and polybrominated 
      diphenyl ethers (PBDEs), in these sediments were analyzed. The results showed 
      that the average content of SigmaPAHs in sediments of Hengshui Lake was 875.49 
      ng.g(-1) and 1010.17 ng.g(-1) in August 2018 and March 2019, respectively. 
      Compared with other regions in China and abroad, SigmaPAHs in sediments from Hengshui 
      Lake were at moderate pollution level. Distribution of SigmaPAHs varied between 
      different sites, but the values changed within a narrow range in different 
      seasons. Sources of PAHs in sediments from Hengshui Lake were complex, but 
      combustion of wood and coal was the main source, followed by oil pollution. 
      Generally, the ecological risk of PAHs was at a low level. However, fluorene 
      pollution control should be strengthened. For SigmaOCPs, the average values in 
      sediments were 35.57 ng.g(-1) and 38.39 ng.g(-1) in August and March, 
      respectively. Compared with other regions, the pollution of SigmaOCPs was at a 
      moderate level. In addition, the distribution of SigmaOCPs varied a small amount 
      between different sites. There were significant differences between the two 
      seasons. The contents of DDTs in sediments were mainly related to the residual 
      DDTs after long-term soil weathering and the input of recent DDTs sources. 
      Contents of HCHs in sediments were influenced by the use of HCHs in industrial 
      history and inputs of agricultural lindane. Generally, the ecological risk of 
      OCPs was at a medium level, but the DDTs pollution control should be 
      strengthened. For SigmaPBDEs, the average values were 1.77 ng.g(-1) and 1.45 ng.g(-1) 
      in the sediments in August 2018 and March 2019, respectively. Compared with other 
      regions, they were at a lower pollution level. The distribution of SigmaPBDEs showed 
      small differences between different sites, and did not obviously vary between 
      spring and summer. The PBDEs in sediments were mainly low-bromine PBDEs, which 
      might be contaminated with penta-BDEs from textiles and foams. Additionally, 
      PBDEs were also probably input by distant settlement and migration from the 
      atmosphere, and soil flushing into the lake. PBDEs posed no immediate ecological 
      risk.
