Du plomb dans les jouets ? Un contrôle s’impose.
Une grande partie des jouets vendus sur les marchés américains et européens est fabriquée en Chine. Or ceux-ci connaissent de vives critiques en ce qui concerne la qualité au vu de la présence de matières potentiellement dangereuses, susceptibles d’aboutir à des actions de rappel et réclamations de dommages et intérêts onéreuses. Plus les cas signalés sont nombreux, plus les consommateurs hésitent à acheter des articles venus de Chine, ce qui justifie donc un contrôle sans failles dans l’intérêt des fabricants. Depuis l’entrée en vigueur de la directive européenne RoHS (Restriction of Hazardous Substances), la limitation de l’utilisation dans les biens de consommation de substances telles le plomb, le cadmium ou le mercure, est clairement réglementée.
What Hair Reveals
The detection of illegal drugs and pharmaceuticals plays a role in various fields, for example in forensic science, road traffic accidents, in competitive sports or at the workplace. Chemical substances can be detected in blood, saliva, urine and in hair. Hair has the great advantage of storing the substances for a long period, which means that detection is still possible several months after consumption of the drug. In addition to the detection of drugs, hair samples are also used for DNA analysis as well as for the analysis of heavy metals and minerals.
Green Chemistry in the Lab
Mechanochemistry is a very effective method to carry out syntheses without solvents and by-products. The technical literature describes a great number of reactions where a conversion of 100% is achieved. A precondition for the establishment of mechanochemistry in the industrial sector is the availability of suitable laboratory mills. A decisive factor is that – similar to conventional preparative chemistry – ambient parameters such as pressure and temperature can be documented and monitored. The Planetary Ball Mills and Mixer Mills from Retsch fulfill these requirements.
Size reduction within the context of sample preparation
In general “size reduction” is taken to mean the disintegration of solid substances by mechanical forces without altering their state.
Tracking Down Fake Cashmere
Cashmere wool is the best known precious wool. It is won from the cashmere goat which originates from the high mountain region of the same name. Due to its properties such as softness and warmth, cashmere wool gains more and more popularity in the manufacture of clothing. Genuine cashmere is won solely from the goat’s downy hair and must possess a certain hair structure with an exactly defined length and thickness.
What hair reveals
The detection of illegal drugs and pharmaceuticals is important in areas such as forensic science, traffic or competitive sports. Chemical substances can be detected in blood, saliva, urine and hair, the latter having the advantage of storing the substances for a fairly long period, depending on the hair length. In addition to the tracing of drug abuse, hair samples are also used for DNA analysis.
