Fats and oils are recognized as essential nutrients in human diets and are presented in varying amounts in many foods. They provide the human body with a concentrated source of energy and supply essential fatty acids that are precursors for important hormones. The quality of edible fats and oils is assessed through parameters such as iodine value (IV), trans content, peroxide value (PV), anisidine value (AV), saponification number (SN), free fatty acids (FFA), and solid fat content (SFC). The traditional chemical ...

In recent years, new regulations have been introduced governing emissions from ships. With the International Maritime Organization (IMO) adopting Annex VI of MARPOL designed to limit sulphur oxides (SOx), nitrous oxides (NOx) and particulate matter emissions, as well as introducing emission control areas (ECAs) to reduce emissions of those air pollutants further in designated sea areas, ship owners/operators can face hefty fines for failing to meet these new requirements on the “polluter pays” ...

The history of air pollution regulation dates back as far as the 13th century when in 1273, Edward I (Longshanks) of England prohibited the burning of sea coal in London. The smoke produced by its combustion was considered detrimental to human health. By the late 19th and early 20th centuries, regulations were being passed that sought to control air pollution predominantly for smoke and odour control. Traditionally, regulators were concerned with the visual impact of the discharge from a stack or chimney. ...

Comparison of Technologies A gas chromatograph (GC) has traditionally been the technology of choice for laboratory analysis of gas samples. GCs have been used for over 50 years in the qualification and quantification of complex mixtures of gases. The techniques and methodology required to run GCs are often a pre-requisite for any laboratory technician. Recent developments in Fourier Transform Infra-Red (FTIR) gas analysis has enabled this technology to start to replace GCs in the ...
