• 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

• Titanium dioxide from sunscreen is polluting beaches
  

  Scientists have found that sunscreen from bathers releases significant quantities of polluting TiO2 (titanium dioxide) into the sea. This has the potential to harm marine life. This work, which comes from research on beaches in the South of France, was presented at the Goldschmidt geochemistry confe more

Bacteria Found to Produce Compounds Toxic to Humans

A Scripps Oceanography-led research team discovered for the first time that a common marine sponge hosts bacteria that specialize in the production of toxic compounds nearly identical to man-made fire retardants. 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

• Cytotoxicity studies of selected cadmium-based quantum dots on 2D vs. 3D cell cultures

  In our work, the cytotoxicity of selected, cadmium-based quantum dots with various surface architectures was studied on 3D spheroids. A specially designed microsystem as a tool for three-dimensional cell culture and nanoparticle toxicity evaluation was used for this aim. Two types of hydrophilic qua more

• Structural investigations of SnS1-xSex solid solution synthesized from chalcogeno-carboxylate complexes of organo-tin by the colloidal and solvent-less route

  Tin chalcogenides are important semiconducting materials due to their non-toxicity, cost effectiveness and layered structure. In this study, a facile synthetic route has been used for the synthesis of a bis(selenobenzoato)dibutyltin(IV) complex, and used along with the bis(thiobenzoato)dibutyltin(IV more

• Implementation of a logic gate by chemically induced nitrogen and oxygen rich C-dots for the selective detection of fluoride ions

  The widespread pollution of fluoride ions in the environment badly affects the ecological system due to their high toxicity, mobility and the difficulty of their degradation. So, there is a need to design an environmentally friendly, highly selective and sensitive probe for their detection. Here, we more

• Production and Market of Malathion in China

  Malathion, a broad-spectrum, low toxicity and low price organophosphate insecticide, has been used in China for about 40 years. Currently, China’s malathion industry is still largely domestic-focused, with no more than 1,500 tonnes exported in 2008 for example. Low toxicity is one of malathion’s l more

• Production and Market of Lambda-cyhalothrin in China

  As one of the pyrethroid insecticides, lambda-cyhalothrin has been widely used in such agricultural products as cotton, fruit trees and vegetables for insect pest control thanks to its high efficiency and low toxicity. From this report, you can figure out basic info of Chinese lambda-cyhalothrin i more

• China Glyphosate Industry Report, 2007-2008

  Pesticide mainly consists of three categories: herbicide, insecticide and bactericide. In China, the most general pesticide we currently use is insecticide which occupies nearly 50% of the total use in pesticide. That totally differs from the international situation that the herbicide's use occupies 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
