#Taraxacum #officinale (#Cichorieae) is native to Eurasia; it serves as a #pollensource for numerous insects and also is #indicatorplant for #calcium/#potassium. Its parts are relevant #foodsources. In their studies in Armenia B. Babayan et al. (2025) found concentrations of #heavymetals in the #soil leading to #DNApolymorphisms and thus being well-suited as a #bioindicator for #ecotoxicology.

Ecotoxicology is the scientific study of the effects of toxic chemicals on biological organisms, specifically at the population, community, and ecosystem levels. The field integrates toxicology and ecology to assess how natural and synthetic pollutants disrupt biological functions, impact biodiversity, and alter ecological dynamics.

Ecotoxicology: In-Depth Description

Ecotoxicology plays a vital role in safeguarding environmental stability, preserving biodiversity, and supporting the "One Health" framework.

The short documentary 'Parkinson tóxico' (in Spanish, but you can add translated subtitles) reveals the connection between pesticides and Parkinson. It is part of a campaign to recognize pesticide-derived Parkinson, one of worlds quickest growing neurodegenerative diseases, as a workplace hazard for farmers and fieldworkers (and of course, to reduce pesticide use).

Scleractinian #corals function as biological archives, absorbing and accumulating anthropogenic compounds—such as pharmaceuticals, herbicides, and personal care products—within their tissues. This process provides a time-integrated record of chemical exposure and pollution in marine ecosystems.

"To determine global pesticide risk, the study researchers looked at data on pesticide use from 2013 to 2019 in 65 nations that collectively represent nearly 80% of global crop acreage. They then combined these statistics with data on the toxicity of 625 pesticides for eight different species groups, including aquatic invertebrates and plants, fish, pollinating insects, soil organisms, and terrestrial arthropods, plants and vertebrates."

This TAT [total applied toxicity] is a very good approach to measure ecotoxicity. This is very important since the often used "tons of pesticides applied" is quite useless when we are talking about substances with highly varying toxicity. 👌

Of many pesticides, we do not really know the toxicity, or there is a lack of scientific consensus because the agrochemical corporations play dirty and have an army of paid pseudo-scientists. Additionally, toxicological studies focus mainly on acute toxicity on humans and not on long-term adverse health effects or the effects of combinations of different pollutants. And the toxicity for ecosystem functions is seldom even considered.
May this TAT help us to not underestimate toxicity so much.

Effects of triclosan at different salinity levels on swimming behavior, reproduction, and antioxidant status in the marine rotifer Brachionus plicatilis

<p xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" class="first" dir="auto" id="d8194589e77">Many cosmetics, toothpaste, medical devices, disinfectants, and household products use triclosan (TCS) as an antibacterial compound. However, many studies have shown increased ecotoxicity in various freshwater and marine ecosystems upon exposure to TCS. Rotifers are zooplankton that significantly impact the ecological processes of the ecosystem to which they belong. Rotifers are also popular in ecotoxicity studies because they have short lifespans, are small and inexpensive, are simple to culture in the laboratory, and make up a substantial percentage of the marine zooplankton community. This research article focuses on how toxic TCS affects rotifers at various salt concentrations. The locomotor and reproductive activity were accessed, and antioxidant activity and lipid peroxidation assays were performed to investigate the effect of TCS on the oxidative status of the rotifer. It was observed that there was a significant change in locomotor activity (swimming speed in μm/sec), oxidative stress marks such as antioxidant defense (superoxide dismutase, catalase, glutathione-S-transferase activity in U/ mg protein), and lipid peroxidation (thiobarbituric acid reactive substances in μM/mg protein) in rotifers when exposed to sublethal concentrations of TCS (100 ng/L and 200 ng/L) in different salinity levels (3 psu and 30 psu). This study shows that TCS can affect rotifers’ swimming and reproductive patterns in varying salinities and cause cellular toxicity. </p>
