  • Non-toxic alternative for next-generation solar cells

    The team of researchers, from the University of Cambridge and the United States, have used theoretical and experimental methods to show how bismuth - the so-called "green element" which sits next to lead on the periodic table, could be used in low-cost solar cells. Their results suggest that solar c more

  • Bacteria in marine sponge produce toxic flame retardant-like compounds

    A Scripps Institution of Oceanography at the University of California San Diego-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. The new findings put the resea more

  • Preventing lead spread

    While lead pipes were banned decades ago, they still supply millions of American households daily with drinking water amid risks of corrosion and leaching that can cause developmental and neurological effects in young children. One common abatement: Dig up old lead lines and replace a portion of the 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

Market studies Toxicity

  • 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
