During economic growth, anthropogenic activities have exerted detrimental impacts on the tidal flat ecosystems in South Korea. Although scholars have conducted extensive research on the ecological quality of tidal flats in South Korea, most have primarily focused on benthic indices. Hence, we utilised two heavy metal indices and five benthic indices to assess the ecological quality in the tidal flats comprehensively. In our study, although heavy metals and total organic carbon concentrations were low in Garolim Bay, the final ecological quality at most stations was unacceptable (63%). The Benthic Opportunistic Polychaetes Amphipods Index (BOPA) demonstrated commendable outcomes in correlation and kappa analyses. However, the BOPA still had some limits. We believe that using multiple indices to assess the ecological quality in the tidal flats of Garolim Bay is more robust than using a single index.

“…The BPI, which was developed based on the ecological environment of the Yellow Sea and is widely employed in South Korea [48][49][50][51], also has its limitations. Notably, when there is a significant abundance of N1 and N2, the BPI tends to overestimate ecological quality [52].…”

As the global population continues to grow, sandy beaches, one of the most valuable ecosystems, have been widely impacted by human activities. Therefore, to develop policies for the conservation and management of sandy beaches, the impact of human activities on sandy beaches must be accurately assessed. We used seven benthic indices to evaluate the ecological quality of sandy beaches in Anmyeon Island, Korea. However, these seven indices were found to either over- or underestimate their ecological quality. Moreover, despite incorporating beach morphodynamics into our study, these indices did not respond to the pressure of urbanisation on beaches. Given the suboptimal performance of benthic indices in reflecting the actual state of Korean beaches, our study indicates that beaches without human interference but with the same morphodynamics must be selected as control groups to further explore the effectiveness of these indices. This is critical for advancing our conservation efforts and managing sandy beach ecosystems under increasing human influence.

With the rapid development of the South Korean economy, human activities have extensively affected Korea’s coastal environment. A precise ecological quality assessment remains paramount despite the relatively lower impact of human activities on the East Sea compared to the West and South Seas of South Korea. Accurate ecological quality assessments can provide valuable marine environmental protection and management references. In our study, we employed seven indices based on heavy metals and macrobenthos to comprehensively assess ecological quality. Our results indicated the final ecological quality in the central East Sea of South Korea was acceptable at most stations; however, the ecological quality in winter marginally falls short compared to that in spring. The concentration of heavy metals emerges as a significant determinant of the final ecological quality, underscoring the need for subsequent studies to investigate the origins of heavy metals in the central East Sea of South Korea and the influence of anthropogenic activities on heavy metal concentrations. Furthermore, employing a single biotic index proves challenging for accurately assessing ecological quality in the East Sea of South Korea.
