“Le 3e Plan Santé Au Travail Inscrit Les Produits Chimiques Parmi Les Risques Prioritaires”
25858_une“10 Décembre-La prévention de l’exposition aux produits chimiques est identifiée comme l’un des risques prioritaires du PST 3. Amiante, nanomatériaux et perturbateurs endocriniens sont particulièrement ciblés.
Le Conseil d’orientation des conditions de travail (COCT) a adopté mardi 8 décembre le troisième Plan santé au travail (PST 3), qui constitue la feuille de route du Gouvernement dans ce domaine pour la période 2016-2020. « Ce plan marque un infléchissement majeur en faveur d’une politique de prévention qui anticipe les risques professionnels et garantisse la bonne santé des salariés plutôt que de s’en tenir à une vision exclusivement réparatrice », a déclaré la ministre du Travail.

“Skin Matches Lung Absorption of Phthalates”
skinchemicals_SI_850“Some people assume that the majority of pollutants enter the body through breathing; however, a new report by Science News suggests that equal amounts of some pollutants can enter the body via the skin.
As the body’s biggest organ, skin can serve as a sponge for such chemicals, said John Kissel, environmental engineer at the University of Washington in Seattle in the report.
“If the whole body is exposed, then even low rates of exposure can deliver what turns out to be nontrivial amounts of these chemicals,” he explained.
Phthalates Exposed
Phthalates are an example of harmful chemicals, which are used as solvents and building blocks for plastics. Due to their extensive use, phthalates are found throughout the environment and in people’s bodies. Studies have linked exposure to phthalates with changes in mental activity and reproductive organs for babies, young children and babies in utero. (…)”

“Heavy Metals, Pharmaceuticals and Endangered Species DNA Found in Traditional Chinese Medicines, Research Finds. “

“Some traditional Chinese medicines are laced with pharmaceuticals, heavy metals and even endangered animals, new research has revealed.
« Some traditional Chinese medicines are laced with pharmaceuticals, heavy metals and even endangered animals, new research has revealed.
Traditional Chinese medicines (TCMs) have long been thought by some as a more natural, herbal approach to curing ailments.
But now a study carried out by Curtin University, Murdoch University and the University of Adelaide has found 90 per cent of 26 widely available medicines tested were not fit for human consumption.
Key points:

• Study found 90pc of 26 widely available medicines not fit for human consumption
• Half contained illegal substances, including toxic metals, prescription medication, stimulants
• Some contained arsenic, lead, Viagra, rat poison and DNA of endangered species
• Researcher says ‘honour system’ of TGA listing being exploited
Half contained illegal substances, including toxic metals, prescription medications, stimulants and animal DNA, none of which were listed on the product’s label.

TCMs are a multi-billion-dollar industry and it is estimated 50 per cent of Australians have used alternative therapies at some point.
Researchers employed a new method involving highly sensitive DNA sequencing, toxicology and heavy metal testing to assess the composition of the TCMs.
« If we don’t know what’s in them, it’s very difficult to predict the interactions, … that’s obviously of great concern if they are been given to children, or pregnant women, the potential outcomes there are very serious.

The study does not disclose the brands of medicines checked, but confirmed they were purchased in Adelaide and available for sale in retailers and markets nationally.
Curtin University lead researcher Professor Michael Bunce said the results were shocking.
« Half of them have illegal ingredients in them, we’ve determined from DNA, half of them have got pharmaceuticals added to them that are clearly synthetic in nature and have not come from natural compounds, » he said.
« Another proportion of them have heavy metals beyond the safe ingestion recommendations … 90 per cent of them are really not fit for human consumption. »
Murdoch University biochemist Dr Garth Maker said contamination by undisclosed pharmaceuticals was a health concern.
He said over-the-counter drugs like paracetamol and ibuprofen were found but also steroids, blood thinner warfarin and even sildenafil, the active ingredient in Viagra.
« We were surprised but at the same time, there definitely seems to be an element of deception in designing these things to have a specific outcome, » he said.
« They may contain ephedrine, which will give a lot of people a buzz, and therefore they feel good and they think ‘this is fantastic medicine, I should keep taking it’. »
