Among the topics are the sustainability assessment of energy policies and technologies, applying life-cycle engineering to material selection, environmental implications of erosive rainfall across the Mediterranean, environmentally friendly methods for extracting and determining organophosphorus and organochlorine pesticides, metals and sustainable development, and assessing the impact of environmental management systems on the financial performance of firms.

In the journal Nature Chemical Biology, they showed that judicious doses of organophosphorus nerve agents caused levels of anandamide and 2-AG to rise 10-fold, and suggest this could lead to drugs which work by boosting the body's natural painkillers.

A polymer elastomer fills in the nonwoven fabric and the superfine fibers comprise an organophosphorus component-copolymerized polyester.

The amount of organophosphorus pesticides, which are known to cause neurologic effects in humans, in the children's urine was measured.

and Rhodia SA in Paris, France, have reached an agreement for Albemarie to acquire Rhodia's global Antiblaze organophosphorus and ammonium polyphosphate flame retardants business for applications in rigid and flexible polyurethane foams and flexible vinyls.

In lab tests, scientists nearly doubled the activity levels of an enzyme called organophosphorus hydrolase, known for its potential for biosensing and decontaminating poisonous agents.

As a starting point, he and a colleague, Michelle Cox, of the University of Sydney, have reviewed what we know of the effects of organophosphorus and carbamate insecticides on vertebrates.

Until now, one has only been needed for organophosphorus sheep dips but Food Safety minister Jeff Rooker announced the scheme would be extended to cover all sheep dips from January 1, 1999.
