  • Plastic consumer products contain harmful and unknown substances

    Plastic products are ubiquitous. Although considered indispensable in many areas of life thanks to their versality and practicality, are they really harmless? The PlastX research group led by the Institute of Ecological Research (ISOE) has examined everyday products made of plastic and found that th more

  • ECETOC Task Force provides new insights

    A Task Force set up by the European Centre for Ecotoxicology and Toxicology of Chemicals (ECETOC) has provided new insights into scientific testing for the impact of undissolved particles in the aquatic environment. ECETOC launched the Task Force in response to increasing concerns among the scientif more

  • Sustainable 'nano-raspberry' to neutralize poisonous carbon monoxide

    Scientists from the Nagoya Institute of Technology (NITech) in Japan have developed a sustainable method to neutralize carbon monoxide, the odorless poison produced by cars and home boilers. Traditionally, carbon monoxide needs a noble metal - a rare and expensive ingredient - to convert into carbon more

Natural vs. Man-Made Chemicals

The term ‘chemophobia’ has been used on social media amongst chemists with increasing regularity over the past year. Defined as ‘a fear of chemicals’, more specifically it refers to the growing tendency for the public to be suspicious and critical of the presence of any man-made (synthetic) chemical more

The Chemistry of Poisons

This graphic is the first in a planned series looking at the effects and chemistry of a range of different poisons. As such, it seemed appropriate to start with one of the most well known poisons: arsenic. Arsenic has been used by poisoners for centuries, primarily in the form of white arsenic, or a more

The Chemistry of Deodorants vs. Antiperspirants

Deodorants and antiperspirants are products that the majority of us make use of everyday. The two terms aren’t interchangeable, however; there is a difference in the manner in which they act to reduce body odour. Today’s graphic is a collaboration with ACS Reactions looking at the chemical compounds more

  • The Right Dose

    Although acute toxicity studies in animals are an indispensable prerequisite for the ­realisation of clinical trials in humans, these can only be projected to humans to a limited extent, and thus are scientifically problematic and ethically questionable. Therefore, the international regulatory authorities increasingly recommend the use of alternative in vitro methods in the framework of safety studies in accordance with the ”3R Principle“ (Replacement, Reduction, Refinement). more
