Active atmospheric carbon dioxide removal (CDR) is needed at a gigaton scale in the next decades to keep global warming below 1.5 °C. Coastal enhanced silicate weathering (CESW) aims increase natural ocean sequestration via chemical of finely ground olivine (MgxFe(1-x)SiO4) rich rock dispersed dynamic coastal environments. However, environmental safety technique remains question due high Ni and Cr content olivine. Therefore, we investigated short term bioaccumulation chronic toxicity marine amphipod Gammarus locusta. Acute 24-h exposure resulted significant grain size dependent ingestion subsequent accumulation tissues. Thousands small (mainly ≤ 10 µm) grains were ingested by G. locusta, but their importance for trace metal requires additional research. Most egested within 24 h. Chronic 35-day (3-99 reduced survival, growth, reproduction, likely as result induced oxidative stress disturbance major cation homeostasis. Amphipod reproduction was significantly concentrations 10% w/w higher. In context ecological risk assessment, application an arbitrary assessment factor 100 highest no observed effect concentration 1% yields very low predicted no-effect (PNEC) 0.01% This PNEC value highlights urgent need data accurately assess environmentally safe climate change mitigation.

Plant-extracted essential oils are generally suggested as potential sources for alternatives to synthetic insecticides in insect pest control strategies. The increased interest the use of derives from generalized perception their safety environment, human health, and non-target organisms well a lower risk resistance development. However, studies on have largely focused activity targeted pests while overlooking unintended effects biological reproductive traits, especially with sublethal exposures. Here, we first determined toxicity Eucalyptus globulus oil adults Drosophila suzukii assessed low concentrations (i.e., LC5 LC20) old (5–7 days) mated flies. Subsequently, longevity fecundity newly emerged virgin flies four couples’ combinations: unexposed couples, exposed females, males, couples concentration LC20. Our results show that eucalyptus has good insecticidal against D. suzukii. compared untreated flies, exposure enhanced females’ only when both female male were exposed, but not males’ life span was extended where females exposed. findings suggest although may be alternative adult suzukii, its age-, sex-, mating status-dependent stimulatory responses mediated by need considered further investigated.

Despite pleas to consider both evolutionary and multistressor climate change perspectives improve ecological risk assessment, the much needed combination of is largely missing. This especially important when evaluating costs evolution genetic tolerance pollutants as these may become visible only under combined exposure pollutant warming due energetic constraints. We investigated chlorpyrifos in Daphnia magna sequentially exposed 4-day pesticide treatments heat spike treatments. Exposure reduced fitness chlorpyrifos-sensitive clones (reduced survival, mass, reproductive performance), while it had positive (hormetic) effects on selected for tolerance. did not find any absence stressors a weak sublethal cost spike. Notably, spike, benefit was nullified chlorpyrifos-tolerant experienced (stronger) synergistic interactions between stronger thermal preceded by pesticide. highlights importance studies correctly assess potential rescue nontarget populations.

The widespread use of bisphenol A (BPA) has led to universal exposure among the population, raising concerns about its health effects. Epidemiological studies have linked environmentally relevant levels BPA obesity. We aimed uncover complex mechanisms by which oral during pregnancy with affects offspring. conducted a two-stage mouse study. In stage 1, we gavaged dams at 0.05, 0.5, and 5mg/kg per day pregnancy, tracked offspring's weight diet 12 wk age. 2, exosomes from BPA-exposed offspring were injected into pregnant mice 3-wk-old males, respectively, observed up wk. then sequenced exosomal microRNAs (miRNAs) in male whose had been exposed checked their expression adipose, liver, serum samples weeks 3, 6, 9, 12. Finally, explored functions miRNAs secreted adipose-derived mesenchymal stem cells, investigated whether they could affect glucose uptake, triglyceride synthesis, genes related lipid metabolism alpha liver cells. Gavage 0.05mg/kg obesity mice, injection also induced similar outcomes next generation pups. Exosomal miRNA sequencing identified differentially expressed associated BPA-induced offspring, revealing sustained high adipose tissue gradual increase over time. Further mechanistic showed that derived BPA-treated cells reduced peroxisome proliferator-activated receptor-gamma fibroblast growth factor 21, leading impaired insulin signaling hepatocytes. Overexpression miR-124-3p hepatocytes mimicked these effects; contrast, knockdown or inhibition exosome secretion reversed them. present study corroborates regulatory function resulting pregnancy. may be key novel molecular biomarker adverse effects chemical https://doi.org/10.1289/EHP14888.
