“…The contamination of sediments with trace metals that has accompanied rapid economic development in many countries has become a serious environmental issue worldwide (Ryu et al 2016;Zhang et al 2015). The concentrations, speciation, sources, and toxicity of trace metal pollutants in sediments have been studied extensively in recent years (Chakraborty et al 2014;Sundaray et al 2011).…”

The Haihe Basin extends over 318,000 km or 3.3% of the total area of China, has a population of over 120 million, and is one of China's most polluted river basins. We investigated the pollution and risks from mercury (Hg) in surface riverine sediments of this basin and found that total Hg concentrations in surface sediments ranged from 0.001 to 1.05 mg/kg and averaged 0.054 mg/kg. Using the modified European Community Bureau of Reference standard method, we found that the exchangeable/acid-soluble, reducible, oxidizable, and residual fractions of Hg accounted for 9.86, 6.54, 11.0, and 72.6% of total Hg, respectively. The riverine sediments in the Da Qing He watershed had the highest anthropogenic enrichment of Hg (enrichment factor >1.5). There was a high potential ecological risk from Hg in the riverine sediments in the upper reaches of the Bei San He and Da Qing He watersheds, the middle reaches of the Luan He and Hei Long Gang watersheds, and the lower reaches of the Zi Ya He watershed. Comparison with risk assessment code showed that the riverine sediments in the Da Qing He, Luan He, and Tu-Hai Ma-Xia He watersheds represented a medium risk, with 16.6, 11.9, and 11.8% of Hg in the exchangeable/acid-soluble fraction, respectively.

“…Moreover, benthic foraminifera can also dominate in low oxygen conditions, which support less diversity with high abundance, because the respiratory oxygen demand of benthic foraminifera is less. This explains their ability to survive in such conditions (Gupta and Machain-Castillo 1993) and also adapt to marine salinity levels (Kasilingam et al 2019) Application of site-speci c multi-indices helps to best describe the ecological status of coastal ecosystems based on the pollution load as well as the benthic diversity (Ryu et al 2016). The AMBI and M-AMBI indices developed by European Water Framework Directive (WFD) provided insights in the ecological health status (Selvaraj et al 2019) of the 14 sampling stations in the southwest coast of Tamil Nadu.…”

The diversity of macro and meiobenthos was documented in order to assess the ecosystem health of an anthropogenically impacted coastal ecosystem for the first time along the southwest coast of Tamil Nadu. Offshore sediment and water samples (n = 63) were collected from 14 sampling stations using the grid sampling method. Water and sediment samples were analysed for environmental variables such as pH, temperature, electrical conductivity (EC), total dissolved solids (TDS), salinity, sulphate, dissolved oxygen (DO), carbohydrate (CHO), protein, lipid, labile organic matter (LOM), total organic carbon (Corg), total organic matter (TOM) and sediment texture using standard methods. Benthic macro and meiobenthos were isolated and identified using standard identification keys. A total of 5 phyla of macrobenthos with 29 species and 5 phyla of benthos with 60 species were identified in the study area. Relative abundance analysis showed that the largest numbers of species belonged to Polychaeta for macrobenthos and foraminifera for meiobenthos. Redundancy analysis indicated that sediment carbohydrate content was the highest determining factor for explaining variation in the diversity of benthos. AMBI & M-AMBI results revealed that among the 14 stations, 2 were categorized as “poor” and 9 as “bad”. Multiple anthropogenic activities in the coastal environment leading to increased organic matter input have resulted in a decline in the ecosystem health of this region, which warrants site-specific management to control organic pollution.

“…AMBI, M-AMBI, and BOPA are all unable to respond to high-intensity anthropogenic pressures [21]. BPI appears to be the most tolerant index compared to H ′ , AMBI, and M-AMBI [22]. In sum, due to the complexity of marine ecosystems, the applicability of different indices may vary within the same region [23].…”

“…In sum, due to the complexity of marine ecosystems, the applicability of different indices may vary within the same region [23]. Therefore, employing multiple indices can provide a more accurate assessment of marine ecological quality than relying on a single index [22,24].…”

With the growing global focus on marine environmental conservation and management, it is imperative to evaluate the ecological quality of marine ecosystems accurately. In this study, we employed seven biotic indices, namely the AZTI marine biotic index (AMBI), BENTIX, benthic opportunistic polychaetes amphipods index (BOPA), benthic pollution index (BPI), multivariate AZTI marine biotic index (M-AMBI), abundance biomass comparison (W-value), and Shannon diversity index (H’), to assess the benthic ecological quality in the intertidal zone of Cheonsu Bay, South Korea. Except for the H’ and W-value, the indices (AMBI, BENTIX, BOPA, BPI, and M-AMBI) suggest that the ecological quality at most stations in the intertidal zone of Cheonsu Bay was acceptable. Furthermore, the influx of a large amount of eutrophic freshwater has impacted the intertidal zone of Cheonsu Bay, but the applicability of the seven biotic indices requires further investigation.
