A broad‐taxa approach as an important concept in ecotoxicological studies and pollution monitoring

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Год журнала: 2023, Номер 99(1), С. 131 - 176

ABSTRACT Aquatic invertebrates play a pivotal role in (eco)toxicological assessments because they offer ethical, cost‐effective and repeatable testing options. Additionally, their significance the food chain ability to represent diverse aquatic ecosystems make them valuable subjects for studies. To ensure consistency comparability across studies, international (eco)toxicology guidelines have been used establish standardised methods protocols data collection, analysis interpretation. However, current primarily focus on limited number of invertebrate species, mainly from Arthropoda, Mollusca Annelida. These are suitable basic toxicity screening, effectively assessing immediate severe effects toxic substances organisms. For more comprehensive ecologically relevant assessments, particularly those addressing long‐term ecosystem‐wide impacts, we recommended use broader diversity since present choice taxa exacerbates scope ecotoxicological This review provides overview focusing major how assess impact chemicals environments. The work supports broad‐taxa approach environmental as it better represents natural populations inhabiting various ecosystems. Advances omics other biochemical computational techniques feasible, enabling mechanistic studies non‐model By combining these approaches with vitro together approach, researchers can gain insights into less‐explored impacts pollution, such changes population diversity, development tolerance transgenerational inheritance pollution responses, organism phenotypic plasticity, biological invasion outcomes, social behaviour changes, metabolome regeneration phenomena, disease susceptibility tissue pathologies. also emphasises need harmonised data‐reporting standards minimum annotation checklists that research results findable, accessible, interoperable reusable (FAIR), maximising reusability data. ultimate goal is encourage integrated holistic problem‐focused collaboration between scientific disciplines, standardisation organisations decision‐making bodies, transdisciplinary knowledge co‐production One‐Health approach.

Nanoplastic exposure inhibits feeding and delays regeneration in a freshwater planarian

Environmental Pollution, Год журнала: 2023, Номер 332, С. 121959 - 121959

Опубликована: Июнь 2, 2023

The concentration of nanoplastics (NPs) is expected to increase in aquatic environments thus potentially threatening freshwater organisms through interactions with plastic particles that variously float, circulate the water column or sink into benthos. Studies mechanisms any NP effects are still scarce, particularly respect regenerative ability biota for which there no recognised model organism. present study therefore aimed investigate behavioural and regeneration responses planarian Girardia tigrina after 10 days exposed along a gradient 0.01-10 mg/L poly (styrene-co-methyl methacrylate) NPs (∼426 ± 175 nm). Exposure induced significant reduction feeding rate even at low concentrations (LOEC 0.01 mg/L), while head was delayed clear dose response way 0.1 blastema length). Planaria locomotion assessed not affected. Our results highlight potential adverse exposure show behaviour benthic organism can be indicators resulting toxicity. Planarians becoming widely used ecotoxicology help address polymers on regeneration.

The Role of Alternative Toxicological Trials in Drug Discovery Programs. The Case of Caenorhabditis elegans and Other Methods

Current Medicinal Chemistry, Год журнала: 2022, Номер 29(32), С. 5270 - 5288

Опубликована: Март 30, 2022

The discovery of a new drug requires over billion dollars and around 12 years research efforts, toxicity is the leading reason for failure to approve candidate drugs. Many alternative methods have been validated detect as early possible diminish waste resources efforts in medicinal chemistry research, vivo are especially valuable amount information they can provide at little cost short time. In this work, we present review literature published between 2000 2021 on screening employed chemistry, which believe will be useful because, addition shortening time, these studies much additional aside from compounds. These models include zebrafish, Artemia salina, Galleria mellonella, Drosophila melanogaster, planarians, Caenorhabditis elegans. most ones last decade were D. C. elegans due their reliability, ease, cost-effectiveness implementation flexibility. Special attention given because its rising popularity, wide range uses, including screening, active effects measurement, antioxidant anthelmintic antimicrobial activities, fast reliable results. Over also became viable high-throughput (HTS) automated option. Additionally, manuscript lists briefly other used initial toxicological analyses role scenarios, classifying them silico, vitro that receiving growing increase interest recent years.

Polycyclic Aromatic Hydrocarbons (PAHs) in Freshwater Systems: A Comprehensive Review of Sources, Distribution, and Impacts

Опубликована: Апрель 30, 2024

This review paper presents a comprehensive synthesis of current knowledge on the contamination water systems by polycyclic aromatic hydrocarbons (PAHs). PAHs, organic contaminants characterized two or more fused rings, are notably problematic due to their persistence, bioaccumulation, and significant health risks. The commences with an examination various sources PAHs in aquatic environments, encompassing both anthropogenic activities, such as industrial discharges, urban runoff, oil spills, natural phenomena including volcanic eruptions wildfires. Subsequently, discussion shifts distribution patterns within different ecosystems, analysis factors that influence transport. Considerable focus is placed entry mechanisms into interactions diverse environmental matrices. Additionally, ecotoxicological effects life scrutinized, particular emphasis molecular, individual, ecosystemic impacts. includes exploration PAH bioaccumulation organisms potential mutagenic carcinogenic consequences. further addresses challenges associated detecting quantifying settings, reflecting advancements analytical methodologies complexities introduced varied physicochemical properties. concludes summary existing regulatory frameworks guidelines governing systems, underscoring imperative for global collaboration monitoring management pollution.
