New data from a BfR human study: no cyanide risk resulting from the consumption of marzipan and persipan


A human study conducted by the Federal Institute for Risk Assessment (BfR) enables more differentiated risk assessment of cyanide exposure following the consumption of bitter apricot kernels, persipan, linseed or manioc (cassava). The study results have now been published in “Archives of ...


Animal testing methods for endocrine disruptors should change, team argues

Review suggests that oral gavage, the accepted method of dosing lab animals to test chemical toxicity, does not accurately mimic how humans are exposed to chemicals in everyday life


Challenging risk assessment methods used for decades by toxicologists, a new review of the literature led by environmental health scientist Laura Vandenberg at the University of Massachusetts Amherst suggests that oral gavage, the most widely accepted method of dosing lab animals to test chemical ...


Royal Society of Chemistry welcomes non-animal test that could spare one million mice worldwide


The Royal Society of Chemistry welcomed the implementation of newly-developed non-animal methods of testing for poisons in shellfish from the seas around Britain which has led to 14,000 mice being spared testing and death in 2012. If the techniques were to be adopted worldwide it could save a ...


Super-strong, high-tech material found to be toxic to aquatic animals

Carbon nanotubes hold promise for industry but need monitoring, say researchers


Carbon nanotubes (CNTs) are some of the strongest materials on Earth and are used to strengthen composite materials, such as those used in high-performance tennis rackets. CNTs have potential uses in everything from medicine to electronics to construction. However, CNTs are not without risks. A ...


Risk re-classified for carcinogenic everyday substance: X-ray expert "decodes" diesel soot


Since June 2012, it is official: The World Health Organisation (WHO) has classified diesel soot as a lung carcinogen. Artur Braun, a physicist at Empa and an X-ray spectroscopy expert, has made crucial contributions to analyzing the structure and composition of soot particles. Soot particles are ...


ECETOC publishes Joint Assessment of Commodity Chemicals (JACC) Report No. 55 on Linear Polydimethylsiloxanes CAS No. 63148-62-9 (Second Edition)


The findings of an ECETOC task force on Linear Polydimethylsiloxanes have been published as ECETOC JACC Report No. 55. This report presents a critical evaluation of the toxicity, physico-chemical properties, and environmental fate and effects of linear polydimethylsiloxanes (PDMSs), a type of ...


The unsolved mystery of kava toxicity


A major new review of scientific knowledge on kava — a plant used to make dietary supplements and a trendy drink with calming effects — has left unsolved the mystery of why Pacific Island people can consume it safely, while people in the United States, Europe, and other Western cultures sometimes ...


New approaches needed to gauge safety of nanotech-based pesticides


Nanotechnology is about to emerge in the world of pesticides and pest control, and a range of new approaches are needed to understand the implications for public health, ensure that this is done safely, maximize the potential benefits and prevent possible risks, researchers say in a new ...


Better animal-free test for chemicals that can cause contact dermatitis


Scientists are reporting development of a fast, simple, inexpensive method for determining whether chemicals in consumer products and workplaces may cause skin allergies in people -- a method that does not involve use of animals. Their study appears in ACS' Chemical Research in Toxicology. Itai ...


Study finds conditions tough for agrochemical innovation

Plant protection R&D costs rise 68.4% in a decade


A new study of Research and Development (R&D) within the crop protection sector shows that, in a decade, the costs associated with the discovery, development and registration of new crop pest and disease agents have increased by 68.4 per cent to €189m. The research, conducted by agribusiness ...
