A recent Pitt study found that a four-day testing period for pesticide exposure may not account for long-term effects on humans and animals. The highly toxic pesticide endosulfan exhibited a 'lag effect' with delayed toxicity surfacing after direct contact had ended.
A study of 1060 vets in north Germany found that psychosocial stress increased with working hours, leading to demoralization and substance abuse. The research suggests a complex relationship between stress, tobacco consumption, problem drinking, and drug use.
A new methodology developed by Pedro Álvarez Lloret found that exposure to organochlorate pollutants and lead causes bone weakening and fracture in wild birds. The study also reveals that polychloro-biphenyl (PCB) increases bone maturity, making them more fragile.
The Center for Environmental Implications of NanoTechnology (CEINT) aims to define the relationship between various nanomaterials and their potential environmental exposure and ecological consequences. Researchers plan to develop a rigorous risk assessment framework, collaborating with policy-makers and society.
The University of North Carolina at Chapel Hill School of Public Health has received a $3.4 million grant to develop the Carolina Center for Computational Toxicology, which aims to advance computational toxicology by developing new methods and tools.
Research highlights diacetyl's acute toxicity and respiratory harm when inhaled by humans. Studies have found that diacetyl can injure lungs, particularly among workers making microwave popcorn and flavoring chemicals.
UC Riverside scientists warn that chemicals used to slow the spread of fires in consumer goods, such as televisions and sofas, can be found in high concentrations in human blood and breast milk. Long-term exposure to these chemicals may pose a health risk, particularly for infants and toddlers.
A recent paper identifies Five Grand Challenges for research on nanotechnology risk to meet the full potential of the technology. The challenges include developing a universal aerosol sampler, assessing fiber-shaped nanoparticles' health hazards, and engineering safe-by-design nanomaterials.
Fourteen top scientists propose five critical challenges for nanotechnology risk research, including identifying potential health and environmental hazards. They will discuss their recommendations at a live webcast on November 16th, 2006.
Dr. Kenneth Olden has received the Society of Toxicology's Public Communications Award for his efforts to bridge the gap between researchers, policymakers, and the public through open access journals and regional town meetings.
Recent safety studies by the National Toxicology Program will be reviewed by a public meeting on May 18. The studies include chloral hydrate, napthalene, and indium phosphide.
A new archaeon, Ferroplasma acidarmanus, is found in mining sites and accelerates the production of sulfuric acid, a major environmental pollutant. The microbe's ability to thrive in acidic conditions without a cell wall defies conventional understanding.
The NYU Center for Particulate Matter Health Research is conducting studies to identify tiny particles in polluted air that contribute to respiratory ailments, including asthma and chronic obstructive pulmonary disease. The center aims to establish specific chemical species responsible for mortality and morbidity associated with exposure.
Jeff Wheelwright, a renowned environmental writer, has won the American Chemical Society's James T. Grady-James H. Stack Award for Interpreting Chemistry for the Public. His work aims to ease public fears about chemicals in the environment and promote understanding of chemistry.
A Cornell University study suggests that chelation therapy used to treat lead poisoning in children may have adverse effects on the developing immune system. The therapy, DMSA, was found to impair immune function in offspring of pregnant rats who received the treatment during pregnancy.
A new study found that children retain more simulated air pollution per unit of lung surface area than adults, suggesting they are more susceptible to illnesses caused by polluted air. Researchers will extend their studies to exercising volunteers to further understand the effects of particulate air pollution on children.
A University of Georgia researcher's study found that many PCBs in the environment may not be as carcinogenic as previously believed. The project aimed to re-evaluate the toxicity of PCBs based on new scientific information and changes in cancer classification.
