Evaluation of the Toxicity, Morphological and Behavioural Effects of Pelargonium graveolens Essential Oil in Artemia franciscana, Along With Its Antimicrobial Activity

Flavour and Fragrance Journal, EarlyView.
Essential oil of Pelargonium graveolens exhibited potent antimicrobial activity against bacterial and fungal pathogens, while higher concentrations induced mortality and altered swimming behaviour in Artemia franciscana. These findings highlight its therapeutic potential and underscore the importance of defining safe concentration ranges to support ...

Prognostic bioindicators in severe COVID-19 patients

Cytokine, 2021
Background Severe acute respiratory syndrome caused by novel coronavirus 2 (SARS-CoV-2) emerged in Wuhan (China) in December 2019. Here we evaluated a panel of biomarkers to phenotype patients and to define the role of immuno-inflammatory mediators as ...

Metal Accumulation, Liver Histopathology, and Human Health Risk Assessment Across Different Trophic Guilds in a Mining‐Affected Neotropical River

Journal of Applied Toxicology, EarlyView.
ABSTRACT Metal pollution in aquatic environments represents a recurring global concern; however, traditional paradigms often assume linear bioaccumulation patterns that may fail under catastrophic contamination scenarios. This study evaluated metal concentrations in water, sediment, and tissues of 10 fish species from different trophic guilds in the ...

Detection, counting and characterization of nanoplastics in marine bioindicators: a proof of principle study

Microplastics and Nanoplastics, 2021
Plastic particulates in the environment pose an increasing concern for regulatory bodies due to their potential risk to higher organisms (including humans) as they enter the food chain.

Bioindication of Heavy Metals in Soil by Liverworts [PDF]

Archives of Environmental Contamination and Toxicology, 1997
Studies were made of the accumulation of the heavy metals Ba, Cd, Co, Cr, Cu, Fe, Hg, Ni, Pb, Sr, V, and Zn and the macroelements N, P, K, Ca, and Mg in liverworts Conocephalum conicum, Marchantia polymorphia, and Pellia epiphylla collected from 57 microhabitats in Poland (Lower Silesia, Tatry Mts., and Puszcza Augustowska forest) and one microhabitat ...

Ionic liquids: structure–toxicity relationships, predictive toxicology, and sustainable design

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Ionic liquids (ILs) have often been described as green alternatives to conventional solvents because of their negligible vapor pressure and highly tunable properties. However, low volatility does not necessarily translate into environmental safety, as their biological and ecological effects are strongly influenced by molecular structure.

Plant bioindicators of heavy metals

, 2021
The urban areas are exposed to high risk of contamination, and some of the plant species can indicate this contamination. For this study, plants which can accumulate heavy metals and meet the requirements for bioindicators were chosen.

Ciliates (Alveolata, Ciliophora) as bioindicators of environmental pressure: A karstic river case

, 2021
Ciliates are single celled eukaryotes recognized as key players in the microbial loop of aquatic ecosystems. The present study was carried out on the Krka River (Croatia), a karst freshwater ecosystem characterized by tufa barriers, biomineralization and

Bringing the Lab to the Field: Exploring Water‐Borne Corticosterone as a Physiological Indicator in Captive and Wild Common Frog Larvae (Rana temporaria)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Assessing physiological condition in wild populations is important for understanding how environmental variation shapes organismal performance. Water‐borne corticosterone (WB‐CORT) sampling shows promise for studying amphibian stress physiology, but its ecological relevance and limitations require evaluation, particularly when methods ...
