“…This interplay results in the observed mismatch between environmental concentrations and tissue levels of trace elements in the present study. Similar scenarios were also reported in other studies (Hao et al, 2019;Cano-Rocabayera et al, 2022;Bettoso et al, 2023). A more detailed examination of the bioaccumulation process is warranted for further understanding.…”

“…Additionally, trace elements can be excreted from cells via adenosine triphosphate-binding cassette transporters (Hu et al, 2019). Consequently, the bioaccumulation in tissues does not always linearly correlate with environmental exposure levels, particularly at higher environmental concentrations (Cano-Rocabayera et al, 2022).…”

The goal of this study was to evaluate the trace element pollution in a marine ranching area in China based on molecular responses (expression of metallothionein and antioxidant enzyme genes), and biochemical biomarkers (metallothionein content, antioxidant enzyme activities, and malonaldehyde level) in four indicator species. We collected samples of two fish (Lateolabrax maculatus and Sebastes schlegelii), one crustacean (Charybdis japonica), and one gastropod (Rapana venosa) from the western Furong Island marine ranching area and from an adjacent area in March 2022 and measured the trace element content in these indicator species as well as in the seawater and sediment. We found that the bioaccumulation characteristics of trace elements and the response patterns of biomarkers were species specific. Moreover, not every biomarker was significantly correlated with environmental trace element content. We then established two biomarker combinations indicative of trace element pollution in seawater and sediment, respectively, based on the correlation between biomarkers and trace element contents. The selected biomarkers were integrated using integrated biomarker response version 2 (IBRv2). IBRv2 values in the studied marine ranching area were lower than those in the adjacent area. Additionally, these values were consistent with the bioaccumulation of trace elements in the indicator species, the integrated trace element pollution index for seawater, and the potential risk index for sediment. These results show that this multi-biomarker and multi-species IBRv2 approach provided a comprehensive diagnosis of trace element pollution in the marine ranching area. Therefore, its application may be beneficial for marine environmental monitoring and management in view of the ecotoxicological impact of pollutants on organisms.

“…The Ciliwung River is now highly polluted in every area, from the upstream (Bogor District) to the downstream (Jakarta City), making it unsafe to use for recreational purposes (Elfidasari et al 2018). H. plecostomus can survive in extreme conditions of heavy metal contamination (Cano-Rocabayera et al 2022), making it the dominant species in the Ciliwung River. The heavy metals Pb, Hg, and Cd were detected in H. plecostomus (Loricariidae) from the Ciliwung River using the XRF technique.…”

Abstract. Widiyanti R, Nugroho HA, Megarani DV, Widiasih DA, Pakpahan S. 2023. Multiplex PCR detection of mackerel-based food adulteration with pleco and chicken in selected areas around Ciliwung River, Indonesia. Biodiversitas 24: 1538-1543. Detecting fish product adulteration is crucial to ensure food safety since pleco meat was already reported to carry several heavy metals that might harm human health. Pleco is invasive species in the Ciliwung River and is commonly used as adulteration material for fish-based products. Adulteration in mackerel-based food products may alter the nutritional value and carry heavy metal contamination from the bottom-feeder fish's meat (pleco). Therefore, using the DNA barcoding technique, a molecular approach has been used to authenticate mackerel fish products (including dumplings and otak-otak). This study aimed to develop a specific multiplex PCR method for simultaneously detecting processed products from mackerel and pleco. The sample consists of 21 processed food items initially made from mackerel. The samples were taken in the selected area around the Ciliwung River. All the samples can be amplified successfully, and amplification lengths were 108, 171, and 300 bp, respectively. Analysis from various claimed mackerel products showed that five samples were positive for pleco adulteration, and 11 products contained chicken meat addition. The phylogenetic tree was constructed from selected sequences from our samples and showed that the amplicons were clustered in three clades, mackerel (Scomberomorus), pleco (Pterygoplichthys), and chicken (Gallus gallusLinnaeus, 1758). The findings of this study revealed that 23.80% (5/21) products contained pleco, and 52.38% (11/21) contained chicken meat addition. The addition of an unusual component to food composition may alter nutritional value as well as may affect food hygiene and safety.
