Investigating the presence of organophosphate esters in sediments from a typical fishing port agglomeration in Dalian, North China

Pollution Characteristics and Ecological Impact of Screening Analysis of Fishing Port Sediments from Dalian, North China

“…Unexpectedly, the central fishing port with the highest vessel capacity in this study is not the port with the most severe external pollution. In addition to fishing vessels, other factors may modulate pollution source inputs to fishing ports, or managers may effectively control and manage pollution in central ports, thereby slowing the release of pollutants …”

“…The fishing ports were classified based on the service scope, the number of fishing vessels and the unloading volume, which are shown in Table S2 . Central, first-class, and second-class fishing ports can accommodate more than 800, 600, and 200 vessels for replenishment, respectively, and the unloading volumes of fish cargo can reach over 80,000 tons, 40,000 tons, and 20,000 tons, respectively. , The samples were first air-dried at room temperature for 3–4 days, then sieved through a 60-mesh stainless steel sieve and ground in a grinder. Then, the samples were sealed in polyethylene bags and stored at −20 °C until analysis.…”
