Published: June 26, 2023

Microplastics and pesticides are emerging contaminants in the marine biota, which cause many harmful effects on aquatic organisms, especially fish. Fish is a staple affordable food source, rich animal protein, along with various vitamins, essential amino acids, minerals. Exposure of fish to microplastics, pesticides, nanoparticles generates ROS induces oxidative stress, inflammation, immunotoxicity, genotoxicity, DNA damage alters gut microbiota, thus reducing growth quality Changes behavioral patterns, swimming, feeding habits were also observed under exposures above contaminants. These affect Nrf-2, JNK, ERK, NF-κB, MAPK signaling pathways. And Nrf2-KEAP1 signalling modulates redox status marinating enzymes Effects found modulate antioxidant enzymes, including superoxide dismutase, catalase, glutathione system. So, protect health from contribution nano-technology or nano-formulations was researched. A decrease nutritional population significantly impacts human diet, influencing traditions economics worldwide. On other hand, traces microplastics habitat water can enter humans by consuming contaminated may result serious hazards.

Microplastic pollution has become pervasive. Identifying a bioindicator species to track the occurrence and effects of microplastics (MPs) on ecosystems is crucial for determining their impact environment. The digestive tract Procambarus clarkii was thought be interest investigating MPs accumulation in freshwater organisms. Our hypothesis that same type found abiotic compartments (water sediment) could P. clarkii, which would make it an ideal candidate use as MP ecosystems. Water, sediment, specimens were collected from four sites lentic ecosystem (Lake Candia; northwestern Italy) two consecutive years (2021–2022). mean abundance 1.75 ± 0.95 items/m3 2021 2 0.81 2022 water samples 6.75 1.5 items/kg 8 sediment 2022, respectively.

Ecotoxicological bioassays with terrestrial plants: a holistic view of standards, guidelines, and protocols

Journal of Toxicology and Environmental Health Part B, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 39

Published: Jan. 5, 2025

Terrestrial and aquatic ecosystems face various chemicals that might induce acute and/or long-term harm. To assess these impacts, ecotoxicological bioassays are essential. However, using animals, particularly mammals, costly, time-consuming, raise ethical concerns. In this context, terrestrial plants emerge as a viable alternative to conventional assays. Thus, the aim of review was address history evolution plant bioassays, highlighting main regulations, guidelines, protocols governing use in tests. Initially, were employed cytogenotoxic effects chemicals, gaining prominence with GENE-TOX program 80s. Subsequently, used allelopathy studies aimed examine ecotoxicity pesticides soil. Currently, regulated by specific standards, such ASTM E1963–22, EPA 600/3–88/029, EPS 1/RM/45, ISO 11269-1, 11269-2, 17126, 18763, 29200, 22030, OECD-208, OECD-227, OCSPP 850.4100, 850.4230, 850.4800 OPPTS 850.4200. The existing standardize greenhouse lab environments, duration tests varies from hours months. parameters be analyzed after exposure include germination percentage, survival rate, root length, aerial part fresh mass exposed plants, phytotoxicity symptoms. addition, absorption rate substances genotoxic mutagenic also assessed. Therefore, data demonstrate represent an important tool analysis environmental risks associated serve crucial allies modern ecotoxicology.

First record of microplastic contamination in adult endemic amazonian anuran species

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 18, 2025

Abstract The microplastics (MPs), due to their high dispersion and bioaccumulation rates, have been identified in various animal groups, such as anuran amphibians during both larval adult stages. However, current studies on focus assessing only one exposure route, the digestive system, while other routes remain underestimated. Therefore, this present study aimed evaluate degree of contamination digestive, respiratory, integumentary systems, situ, two endemic Amazonian species ( Physalaemus ephippifer Boana multifasciata ). From this, we characterized microplastic particles for each assessed effects morphometric measures total MP level gastrointestinal tract (GIT). Additionally, determined different indices how they vary according systems. Based our data, showed highest levels species. variations indicated that P. had a higher contamination. Thus, provides first evidence through respiratory anurans it is identify terrestrial biomonitors Amazon.
