WHO regulation on human toxicity helps in reducing acute pesticide poisoning

Current WHO pesticide classifications are based on toxicity in rats but basing regulation on human toxicity will make pesticide poisoning less hazardous and prevent hundreds of thousands of deaths globally without compromising agricultural needs. These are the key findings from a study by Andrew Dawson (South Asian Clinical Toxicology Research Collaboration, University of Peradeniya, Sri Lanka) and colleagues published in this week's PLoS Medicine.

SO2 emission raise health concerns

Kilauea Volcano on Hawaii's big island has been erupting on its east rift since 1983. But, in March 2008, an additional eruption vent opened at the volcano's summit, resulting in about triple the amount of sulfur dioxide gas (SO2) emissions drifting to the local community of Ka'u, raising health concerns over the risks associated with exposure to "vog," as the islanders refer to this volcanic air pollution.

First in vivo screening system for complete human nuclear hormone receptor family

The InDanio screening system can be used, for example, to functionally characterize 'orphan' receptors - those for which their natural ligands or specific function are unknown - and thus qualify them as potential targets for drug discovery. The system can also be used to screen compound libraries in order to identify and refine potential new drugs that target NR proteins.

Cancer cluster among Sydney Harbour Bridge workers triggers investigation

There are reports of a cancer cluster among Sydney Harbour Bridge workers with at least eight known cases that unions believe are linked to the use of lead paint. The Roads and Traffic Authority (RTA) will investigate the matter. Of the eight workers five have already died and all of them had been involved in painting and maintaining the bridge for more than 10 years, the Construction Forestry Mining and Energy Union (CFMEU) said. This included scraping off lead paint, initially with little protective equipment.
