Preparation of soil and sediment samples for the determination of organometallic compounds
PublikacjaZwiązki metaloorganiczne są szeroko stosowane niemal we wszystkich gałęziach przemysłu. W wyniku ich emisji, zarówno ze źródeł naturalnych jak i antropogenicznych, nastąpiło ich rozprzestrzenienie w środowisku, w którym ulegają szeregowi przemian chemicznych. Niektóre z tych związków charakteryzują się wysoką toksycznością. W oparciu o literaturę naukową dotyczącą procedur oznaczania wybranych związków metaloorganicznych rtęci,...

Metrics for green analytical chemistry
PublikacjaGreen analytical chemistry, although not being a new concept, does not have a greenness metrics system. Green chemistry metrics are not suitable for analytical procedure assessment because they often refer to the mass of the product. Some efforts have been made to develop suitable metrics for analytical chemistry. Some are simple to use but do not cover all aspects of analytical methods’ environmental impact. Others are more comprehensive...

The role of analytical chemistry in the study of the Anthropocene
PublikacjaThe term “Anthropocene” refers to not yet formalized epoch of geologic time during which geologic processes have been dominated by the human impact. This impact takes on many forms. Biological, physical and chemical changes to the Earth System caused by anthropogenic activity are recorded in natural archives either as new fossil assemblages (neobiota), anthropogenic deposits or a wide variety of pollutants emitted to the environment....

Greener organic solvents in analytical chemistry
PublikacjaThe paper presents the most recent advances in analytical applications of greener organic solvents. Substitution of problematic solvents with more benign organic ones is much easier than shifting to technique applying alternative solvents, such as ionic liquids or supercritical fluids. In the area of liquid chromatography greener mobile phases, much attention is given to application ethanol or acetone instead of acetonitrile. Solvent-based...

Green analytical chemistry metrics: A review
PublikacjaGreen analytical chemistry encourages reducing the use of toxic chemicals/reagents, using energy-efficient equipment, and generating minimal waste. The recent trends in analytical method development focus on the miniaturization of the sample preparation devices, the development of solventless or solvent-minimized extraction techniques, and the utilization of less toxic solvents. The twelve principles of GAC serve as a basic guideline...
