The report describes the measurement of urinary organic halogen compounds. The method is an application of the adsorbable organic halogen assay which is widely used for the analysis of industrial ...

Halogens are known to decrease the levels of stratospheric ozone. The latest measurements show that something similar occurs in the lower atmosphere over tropical oceans — and probably above most ...

THE FIRST DIRECT atmospheric measurements of iodine oxide and bromine oxide above the Antarctic snowpack unexpectedly indicate that the chemicals participate in destroying ozone and change the ...

Electronics companies have experienced some chemical reactions in the past two decades. Many will recall the European RoHS Directive (Restriction of Hazardous Substances), which came into force in ...

Halogens, specifically chlorine and bromine, are suspected of posing serious dangers to human health and the environment when used as a brominated flame retardant (BFR) or in polyvinyl chloride (PVC).

(Winona, MN) has expanded its line of halogen-free flame retardant (FR) compounds to include nylon and polyester grades. “Development of halogen-free FR materials by RTP has been driven by the global ...

SOME MARINE organisms have a knack for making steroidal compounds containing halogens. Chemists have long tried to do the same thing, because such compounds can be useful, for example, in treating ...

Increasing the recovery of valuable fossil raw materials, avoiding climate-damaging carbon dioxide emission, and stabilizing our energy supply network – these are the three major objectives of a new ...
