“…Standard filter paper was used to filter the digested samples, which were kept in sterilized polythene vials in the freezer [11]. The primary feathers were collected from dead carcasses of waterbirds from the lake for the metals analysis [4]. Double distilled water was used to wash the external metals and other chemicals.…”

Waterbirds may be a good indicator of harmful metal levels in aquatic environments. Waterbirds’ organs and tissues were tested for the presence of pollutants, such as metals. However, very few reports describe the use of bird feathers and their prey in metal analysis. In the present research, seven metals were measured in the tissue, kidney, liver, and feathers of the Indian pond heron, the black-crowned night heron, and their prey species, including crabs, prawns, molluscs, and fishes from a freshwater lake. Metals were examined using an ECIL-4141-double beam atomic absorption spectrophotometer (DB-AAS). Metal concentrations differed considerably in the tissue, kidney, liver, and feathers of the Indian pond heron and black-crowned night heron (p < 0.001). Indeed, this research discovered a good correlation between the metals of prey species and the tissues, kidneys, liver, and feathers of waterbirds that were tested. The regression model explained that the Cyprinus carpio influence the accumulation of metals about 98.2% in tissues, Macrobrachium rosenbergii and Cyprinus carpio around 86.3% in the kidney, the Labeo rohita almost 47.2% in the liver and Labeo rohita nearly 93.2% on the feathers of the Indian pond heron. On the other hand, the Mystus vittatus, Cyprinus carpio, Labeo rohita influence about 98.8% in tissue, the Claris batrachus and Tilapia mossambica around 93.3% in kidney, the Mystus vittatus, Cyprinus carpio, about 93.2% in liver and the freshwater crab (Travancoriana schirnerae), freshwater prawn (Macrobrachium rosenbergii) and a fish (Cyprinus carpio) nearly 93.2% in feathers in the black-crowned night heron. This research evaluated metals in the dead carcasses of waterbirds, a non-invasive biomonitoring technique for pollution. Overall, the investigation revealed that the lake is severely contaminated with metals. Therefore, the management and protection of aquatic habitats, particularly freshwater lakes, should be enhanced to rescue wild species that rely on aquatic ecosystems and to ensure that people have access to clean drinking water.

“…Globally, aquatic environments are declining owing to diverse environmental contamination, notably metal pollution [1][2][3][4]. Heavy metals are harmful toxic substances that contribute to environmental pollution because they alter the physiology and behavior of diverse living forms, particularly top predators in an ecosystem [5,6].…”

“…Toxic metals can render water unsuitable for human consumption and are accumulated also by aquatic biota. Furthermore, contaminated water used for irrigation may contaminate soils and crops and, therefore, toxic metals and other pollutants may reach humans via food chains, thus representing an environmental and public health threat (Goyal et al, 2022;Carvalho, 2017aCarvalho, , 2017b.…”

The concentrations and distribution of thirteen metals and metalloids were investigated in soils, sediments, and two biological matrices (the fish Clarias gariepisnis and the earthworm Pontoscolex corethrurus) from the CECOMAF agroecosystem, in Kinshasa, Democratic Republic of the Congo, in order to assess the impact of anthropogenic activities. The results revealed high concentrations of heavy metals, such as Cu, Zn, As, Cd, Pb, and Hg all above values recommended by sediment quality guidelines and their probable effect levels on biota. According to the calculated Enrichment Factor, soil and sediments ranked from moderately to heavily polluted by Cu, Zn, Cd, Pb and Hg. The Contamination Degree and other ecological risk indices indicated very high contamination and very high ecological risks posed by Cd and Hg, respectively. The Geoaccumulation Index indicated that current metal concentrations in the agroecosystem originated from anthropogenic activities, while the Spearman correlation matrix values indicated that Hg could originate from different sources and pathways than the other metals. It was concluded that metals from unchecked anthropogenic activities have negatively impacted agricultural activities and fish production at the CECOMAF agroecosystem. Action to reduce the contamination level and the ecological risks by remediating and preventing metal pollution in the CECOMAF agroecosystem site is recommended.

“…Microbial communities in water samples were largely affected by the TN, TP, NO 3 (-)-N, and NO 2 (-)-N concentrations, and sediment was affected by Sed-OM and Sed-TN. Tetracycline, oxytetracycline, chlortetracycline, and sulfadiazine are the four dominant antibiotics in the wetland, and they had a major influence on microbial communities in both water and sediment samples (Wang et al, 2017;Han et al, 2019;Goyal et al, 2022;Malyan et al, 2022). Tetracyclines may have contributed more than sulphonamides in the abundance of sul1, sul2, and tetC gens in Honghu Lake (Yang et al, 2016).…”

Massive fish farming for more than two decades, combined with external sources of pollution, deteriorated the quality of water and sediment and damaged the ecosystem in Honghu Lake. Although water quality has been improving, great challenges remain in restoring the healthy function of ecosystems for self-mitigation. With concerns about contaminants in the sediment that might be the source of pollution, water and sediment samples were collected systematically across the wetland. With the 16s rDNA gene sequence and multiple statistical analyses, this study was able to identify locations where sediments were mostly impacted by non-point source pollution from the surrounding agricultural areas and fish farming inside the lake. The clustering analysis identified two distinct clusters coincide with areas with and without fish farming. The LEfSe algorithm successfully distinguished the differentially abundant biomarkers between the two clusters. By combining the GIS techniques with microbial analysis, hotspots with hazardous pathogenic bacteria such as Rokubacteria, Elusimicrobia, and Fusobacteria in sediments were located. This study showed that comprehensive biodiversity analysis combined with spatial analysis could make the microbial information serve well as biomarkers and indicators for environmental and ecosystem restoration.
