New Englanders at Higher Risk for PFAS Exposure Due to Seafood Consumption, Study Finds
A recent study from Dartmouth has found a potential link between higher consumption of seafood and increased PFAS exposure in New England, particularly in New Hampshire. The study analyzed PFAS concentrations in fresh seafood and highlighted the state’s proactive approach to addressing PFAS concerns. The findings underscore the need for further research and potential regulatory measures to address PFAS exposure through seafood consumption in regions with a strong cultural tradition of seafood consumption like New England.
New Strategy for Assessing Applicability of Chemical Reactions Developed by University of Münster Chemists
Chemists at the University of Münster have developed a computer-aided, bias-free method for selecting model substrates to evaluate new chemical reactions, aiming to improve the quality and information content of chemical reaction data and close knowledge gaps. The method is based on the complexity and structural properties of real pharmaceutical compounds, with the goal of lowering the barriers to the application of new reactions in both academic and industrial contexts. The work, published in the journal ACS Central Science, aims to initiate a ‘rethinking process’ in the evaluation of chemical reactions and represents an important step towards standardizing and objectifying the development and evaluation of chemical reactions.
Household Chemicals May Adversely Affect Brain Development, New Study Finds
A new study suggests that everyday household chemicals, found in disinfectants, furniture, and even toothpaste, could have adverse effects on brain development. The study highlights the potential risks posed by these substances to brain health and their potential association with neurological conditions such as multiple sclerosis and autism spectrum disorders. The findings call for more comprehensive scrutiny of the impacts of common household chemicals on brain health and suggest the need for informed decisions regarding regulatory measures or behavioral interventions to minimize chemical exposure and protect human health.
Study Finds Environmental Chemicals Impact Oligodendrocyte Development
A recent study published in Nature Neuroscience has found that environmental chemicals can impact the development of oligodendrocytes, crucial for neurodevelopment. The study identified two classes of chemicals, quaternary compounds and organophosphate flame retardants, that disrupt oligodendrocyte development through distinct mechanisms. The research also demonstrated the impairment of oligodendrocyte development in mice and human 3D organoid models, as well as associations with adverse neurodevelopmental outcomes. This highlights the need for further investigation into the potential impacts of these environmental chemicals on human health.
Study Links PFAS Chemicals in Blood with Increased Risk of Cardiovascular Diseases
Study from DZNE – German Center for Neurodegenerative Diseases links PFAS chemicals in human blood to increased risk of cardiovascular diseases. Even low concentrations of PFAS are associated with unfavorable blood lipid profiles, especially in younger individuals. The findings raise concerns about the long-term impact on public health, highlighting the need for stricter regulations and further research on the health effects of PFAS.
Researchers Develop Energy-Efficient Strategy for Ethylene Synthesis via CO2 Reduction
Researchers at Université Montpellier and other institutes have developed a new strategy to facilitate the energy-efficient synthesis of ethylene via the reduction of carbon dioxide. Their approach involves functionalizing copper catalysts for CO2 reduction using aryl diazonium salts, aiming to address the modest selectivity for ethylene and improve energy efficiency. This breakthrough is expected to have significant implications for the energy industry and environmental sustainability.
Report Highlights Health Hazards of Endocrine Disrupting Chemicals in Plastics and Pesticides
A new report by the Endocrine Society and IPEN highlights the health hazards associated with Endocrine Disrupting Chemicals (EDCs) found in plastics and pesticides. The report raises concerns about the risks to human health and emphasizes the urgent need to address the implications of these chemicals. With EDCs being linked to hormone-related health conditions, the report serves as a wake-up call to the potential risks associated with these chemicals in our daily lives.
Synthesis of Pantetheine Under Everyday Conditions Suggests Origins of Life
Researchers have synthesized pantetheine, a crucial component of acetyl coenzyme A, under everyday conditions, suggesting it could have formed naturally on early Earth. This finding could have implications for the origins of life and the synthesis of biologically crucial chemicals.
New Tech Turns CO2 into Chemicals with 93% Efficiency, Runs Record 5000 Hrs
New tech developed at Huazhong University of Science and Technology in China has achieved a 93% efficiency in turning CO2 into chemicals, running for a record 5000 hours. This breakthrough could revolutionize industrial-scale projects aimed at reducing carbon dioxide in the atmosphere.
Study Reveals High Prevalence of Little-Known Pesticide Chlormequat in Human Bodies
A recent study by the Environmental Working Group found high levels of the little-known pesticide chlormequat in the urine of 77 out of 96 individuals, raising concerns about its impact on human health. The study highlights the potential risks of chlormequat, which has been linked to reproductive and developmental issues in animal studies. With increased levels found in urine samples and regulatory changes allowing its use on imported oats and other foods, the need for rigorous monitoring and regulation of pesticides to safeguard public health is emphasized.
