Summary: This in vivo study investigated the effects of sub-chronic lead (Pb) exposure on the distribution of other divalent metals in mice. The results showed that Pb levels in blood, bone, and hair could indirectly reflect Pb accumulation in the murine brain. Pb exposure altered levels of calcium (Ca), copper (Cu), iron (Fe), and zinc (Zn), but had no effect on magnesium (Mg) levels. The changes in metal ratios may serve as valuable biomarkers for chronic Pb exposure and suggest an involvement of altered distribution of essential metal elements in Pb-induced neurotoxicity.

Summary: The study investigated the chronic toxicity of an aluminum-based galvanic anode on Pacific oysters, highlighting the oysters' sensitivity at high aluminum concentrations and observing biological effects in the digestive gland. Additionally, the bioaccumulation of metals in the anode was measured in oysters' tissues, showing that bivalves accumulated more zinc than aluminum, and exposure time did not significantly affect the bioaccumulation of aluminum compared to zinc.

Summary: Our research aimed to investigate the health impacts of exhaust generated by the combustion of diesel and two different biodiesels. The results showed that exposure to Tallow biodiesel exhaust had the most significant health impacts, including increased airway hyperresponsiveness and airway inflammation; whereas exposure to Canola biodiesel exhaust had fewer negative health effects.

Summary: This study found that Thiacloprid affected biochemical parameters, cell viability, antioxidant biomarkers, and lipid peroxidation in Mytilus galloprovincialis, as well as causing tissue damage. Due to its harmful potential and cumulative effects, Thiacloprid may pose a potential risk to nontarget aquatic organisms and human health. Further investigation is necessary to fully understand the extent of this risk.

Summary: This study aimed to investigate the relationship between adiposity and microplastic bioaccumulation in fish. The results showed that the content of microplastics in fish exposed to high-fat diet (HFD) was significantly higher than that in fish fed a normal diet (ND). Furthermore, HFD combined with microplastic exposure resulted in increased levels of hepatic lipids and liver injury in the fish. Transcriptomic analysis revealed that microplastic exposure interferes with lipid metabolism and energy homeostasis in fish. Therefore, it is important to control plastic usage, implement proper recycling, and avoid blindly increasing fish weight through HFD to protect the quality of economic fish and prevent human consumption of microplastics through the food chain.

Summary: Intentional discharges of produced water from oil production platforms to the marine environment contain a complex mixture of toxicants, including polycyclic aromatic hydrocarbons (PAHs). Early life stages of fish are highly sensitive to petrogenic exposure, and short-term exposure during critical periods of embryonic development may have detrimental effects on larvae health and survival. However, why different periods are more sensitive to exposure than others are not fully understood.

Summary: The study showed that oil-contaminated seafloor resulting from in situ burning clean-up actions does not appear to cause serious effects on bottom-living shrimp, despite the presence of some sublethal effects after exposure, such as temporary reduction in feeding and mild inflammatory reactions and tissue alterations in gill tissue.

Summary: This study examines the long-term impacts of nanoplastics exposure on freshwater crustaceans, specifically Daphnia magna. The results show that at a concentration of 1 mg/L, nanoplastics had little effect on the adult organisms but increased fertility in the third generation. In contrast, mesoporous SiO2 of similar size induced high mortality and decreased fertility and size. Overall, this study suggests that synthetic nanoparticles of different chemistries may disrupt the energy balance of D. magna through multi-generation exposure.

Summary: Fetal alcohol spectrum disorder (FASD) is a common cause of mental disabilities, affecting 1%-6% of all births. This study found that alcohol exposure during the last months of human gestation may disrupt the development of multisensory integration (MSI), which could be the underlying cause of sensory problems in FASD. The findings suggest that alcohol exposure during pregnancy can have long-term effects on sensory development.

Summary: Study on the effects of exposure to trace metal mixtures in wild Mediterranean mussels revealed continuous increase in body burdens of Cu and Pb throughout the exposure period, while Zn accumulation reached a plateau after day 10 in the whole body and gills. Metabolomics analysis indicated that multiple metabolites were down-regulated and multiple metabolic pathways possibly interrupted by the exposure to the mixture of trace metals.

Summary: The study found that high concentrations of neonicotinoid pesticides combined with parasites affected tadpole immune function, but did not impact parasite infection success. Tadpoles exposed to both neonicotinoid + parasite treatments had significantly lower monocyte to leukocyte ratios compared to parasite-only tadpoles.

Summary: The study investigates the effects of long-term exposure to two individual neonicotinoids on northern leopard frog immune function. Results show that exposure to neonicotinoids can alter leukocyte profiles, indicative of a stress response. Future studies should further explore the impact of chronic exposure to neonicotinoids on amphibians' susceptibility to parasites and pathogens.

Summary: Tadpoles exposed to clothianidin at low concentrations exhibited mild physiological stress and oxidative stress response. However, this did not impact the survival, growth, development time, or hepatosomatic index of frogs. Therefore, the implications of these changes on overall health and fitness remain unclear.

Summary: Glucocorticoid hormones play a crucial role in maintaining homeostasis in vertebrates, but prolonged exposure to environmental contaminants may result in elevated GC levels, affecting individual health. Fish exposed to environmental contaminants have higher baseline GC levels than unexposed fish, with those exposed to pharmaceuticals showing even higher GC levels.

Summary: Freshwater biodiversity loss poses a significant environmental threat in today's changing world, yet efforts to address this crisis have received relatively little attention compared to other ecosystems. The Emergency Recovery Plan for Freshwater Biodiversity outlines crucial actions to help reverse the decline, but there is a need for broader, more concerted efforts at local scales to ensure meaningful impact. Relying solely on international agreements to drive change may take too long given the urgent nature of the situation.
