Office of Pollution Prevention and Toxicslaunched a research grants program called Alternative Synthetic Pathways for Pollution Prevention

Paul Anastas coined the term GREEN CHEMISTRY

an annual award was established for achievements in the application of GREEN CHEMISTRY principles

IUPAC Working Party on Green Chemistryfounded

the GREEN CHEMISTRY INSTITUTE (EPA) came into being in the USA. It fosters contacts between governmental agencies and industrial corporations on the one hand, and university research centres on the other

the first international GREEN CHEMISTRY symposium took place

the first national conference devoted to GREEN CHEMISTRY took place in Poland – EkoChemTech’03

GREEN CHEMISTRYGREEN CHEMISTRY (SHORT(SHORT HISTORY)HISTORY)

Our Common Future, also known as the Brundtland Report, from the United Nations World Commission on Environment and Development (WCED) was published

Green Chemistry Program was inaugurated by the US EPA

MM--SPMESPME conclusionconclusionpartitioning mechanism of the extraction, which is characterized by significantly higher linearity range when compared to commercial fibre

enabling highly polar sorbents to be used without the risk of dissolving in polar sample matrix

povides opportunity of application of quite new kinds of materials, which due to low melting temperatures or solubility in water have not been taken into consideration so far in this kind of applications

high extraction efficiency of phenols and VOCs obtainable with M-SPME fibres, comparable and better than the extraction efficiency using commercially available fibres

M-SPME combined with determination by GC may become a powerful, environmentally friendly tool for sampling, isolation and preconcentration of organic pollutants

• applicable on the sample preparation step prior to the finalquantitative determination of analytes on the ppb level

A new tool for evaluation of the greenness of analytical methodology

Eco-Scale = 100 – total penalty points

The result is ranked on the following scale:>75 – excellent green analysis>50 – acceptable green analysis<50 – inadequate green analysis

Penalty points are assigned for amount of reagents, hazards (physical, environmental,

health and occupational), energy used and waste generated in the analytical procedure
