Factors affecting arsenic and mercury accumulation in fish from the Colombian Caribbean: A multifactorial approach using machine learning. ENVIRONMENTAL RESEARCH 2025; 268:120761. [PMID: 39756777 DOI: 10.1016/j.envres.2025.120761] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/01/2024] [Revised: 12/23/2024] [Accepted: 01/02/2025] [Indexed: 01/07/2025]
Abstract
In marine ecosystems, arsenic (As) and total mercury (T-Hg) represent two of the major pollutants, particularly in fish due to their ecology and the affinity of these metal(loid)s with biological cycles. This study assessed the influence of total length, total weight, relative condition factor, and trophic levels of ten marine fish species from the Colombian Caribbean on As and T-Hg accumulation in muscle tissue, as well as the differentiation in accumulated amounts based on fish habitat type. In this context, Balistes capriscus exhibited the highest As median (7949.08 μg/kg), along with Thunnus atlanticus (1567.15 μg/kg), Haemulon flavolineatum (1469.26 μg/kg), and Euthynnus alletteratus (1191.55 μg/kg), exceeding the maximum permissible limit of 1000 μg/kg for human consumption. Evaluated factors displayed complex and non-linear influences on As accumulation: trophic level > total length > relative condition factor > total weight, where all factors except total weight described a negative effect. Conversely, for T-Hg, influences were markedly linear and monotonic: trophic level > total length > total weight > relative condition factor, with all factors exerting a positive effect. The habitat plays a crucial role in the cumulative patterns of As, with demersal fish significantly differing from pelagic and reef-associated species. Results indicate that the accumulation of As and T-Hg in muscle tissue may be mediated by a multiplicity of factors inherent to the species' morpho-physiology and the chemical activity of each pollutant in the ecosystem, along with the feeding ecology and niche occupied by these organisms.

Abstract
Cadmium (Cd) and lead (Pb) levels in blood and tissues of Atlantic bluefin tuna were analysed to gather information regarding their distribution, accumulation and inter-relationships, as well as to examine how sex affects them. In the whole population, the concentration range was from below the detection limit (bone) to 8.512 μg g-1 (liver) for Cd, and from below detection limit (bone and gills) to 0.063 μg g-1 (kidney) for Pb. The median concentration in the muscles (0.008 and 0.029 μg g-1 for Cd and Pb, respectively) was 10 times less than the maximum permitted for consumption. Sex was shown to be an important variable affecting concentrations of Cd in both liver and kidneys, so taking into account sex when interpreting results is highly recommended. The importance of Cd and Pb bioaccumulation in fishery by-products, increasingly important in commercial circuits, is also highlighted.

Abstract
Tetrodotoxin (TTX) is a potent neurotoxin naturally occurring in terrestrial and marine organisms such as pufferfish. Due to the risk of TTX poisoning, fish of Tetraodontidae family and other puffer-related species must not be placed in the EU markets. This restriction applies to fish of the family Molidae even though no data on toxins’ occurrence is available. In this study, the presence of TTX and its analogues was investigated in the main edible tissue (the white muscle) and the main xenobiotics storage organ (the liver) of ocean sunfish Mola spp. (n = 13) from the South Portuguese coast. HILIC-MS/MS analyses did not reveal TTX in the analyzed samples, suggesting an inexistent or very limited risk of TTX poisoning.

Abstract
Heavy metal pollution is related to the fall in European eel (Anguilla anguilla) populations. The Mar Menor lagoon (SE Spain) is home to an endangered population of this species, which is still caught for human consumption. The presence of Pb, Cd and Hg in the livers and muscles and the Se:Hg ratio in muscle of 150 eels from this lagoon were determined. Pb concentrations were higher than those reported from other populations in the world, while Cd and Hg concentrations in the tissues analysed were lower. In terms of food safety, Se concentrations play an important role in sequestering Hg in eels from this lagoon.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2020; 194:110433. [PMID: 32171119 DOI: 10.1016/j.ecoenv.2020.110433] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/30/2019] [Revised: 02/29/2020] [Accepted: 03/03/2020] [Indexed: 06/10/2023]
Abstract
Fish cage farming has been generally banned in some regions since there is growing concern about adverse environmental issue caused by cage culture practices. This paper presents the long-term effects of past cage culture activities on heavy metal accumulation in sediment and fish in one historical cage culture lake (Changshou reservoir, Chongqing, China). Although cages were removed for over one decade in this studied lake, the average concentrations of heavy metals in sediments were still above 2 times higher than their background values, posing a moderate ecological risk. Higher levels of heavy metals appeared in demersal fish who is more susceptible to heavy metals exposure in sediment. Fish consumption would not lead to a significant health risk of most heavy metals. Hg levels in catfish posed a health risk to vulnerable group (children) and specific group (fishermen), whereas the presence of Se decreased Hg toxicity to a safety level. Therefore, it can be speculated that the cage culture activities could influence the heavy metal accumulation in sediment in the long term, however, consumption of current farmed fish in one lake used to carry out cage-culture is safe for local residents.
