... If you were to begin your study of chemistry by looking at substances handy to you, you would most likely encounter more mixtures than anything else. In this section, we will discuss several methods for separating mixtures. As you read about each technique, see how many uses you can identify for it. ...

Bioaccumulation
... Biomagnification refers to the animals at the top of the food pyramid receiving huge doses of accumulated chemicals. At each level of the food pyramid, chemicals that do not get broken down build up in organisms. When the consumer in the next trophic level eats organisms with a chemical accumula ...

Registration, Evaluation, Authorisation and Restriction of Chemicals
Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) is a European Union regulation dated 18 December 2006. REACH addresses the production and use of chemical substances, and their potential impacts on both human health and the environment. Its 849 pages took seven years to pass, and it has been described as the most complex legislation in the Union's history and the most important in 20 years. It is the strictest law to date regulating chemical substances and will affect industries throughout the world. REACH entered into force in 1 June 2007, with a phased implementation over the next decade. The regulation also established the European Chemicals Agency, which manages the technical, scientific and administrative aspects of REACH.
