Development and Validation of a Method for the Detection of Titanium Dioxide Particles in Human Tissue with Single Particle ICP-MS

Ruud JB Peters, Anna K Undas, Joost Memelink, Greet van Bemmel, Sandra Munniks, Hans Bouwmeester, Peter Nobels, Wobbe Schuurmans and Martijn K van der Lee

Abstract

Human biomonitoring studies to determine total titanium (total-Ti) and titanium dioxide (TiO2) particles require very sensitive inductively coupled plasma high resolution mass spectrometry (ICP-HRMS) methods. The result of such studies can only be reliably when used in a risk assessment if the analytical methods are fully validated, as reported here for human liver and spleen.

Organic Pollution in Surface and Core Sediments from the Yangtze River Estuarine Region - Historic Research Study and A Review of Recent Investigations

Peter J Baugh, Simon M Hutchinson, Liu Min, Lizhong Lu, Weigou Zhang, Su Xu, Claire McGill, Helen Ball, Brian Ward, Daniel Marshall and Radja Bougherira

Abstract

The surface and core sediments obtained from the Yangtze River-south coast estuarine region, and analysed by GC/MS after sample preparation, exhibit a range of organic pollutants over depths from the surface to 0.5 m. The target organic compounds identified are in following categories, homologous series of hydrocarbons, polyaromatic hydrocarbons (PAHs) and linear alkylbenzenes (LABs).

DNA Adaptor Technology as PCR Application

Ichiro Kasajima

Abstract

PCR (polymerase chain reaction) is a popular analytical method in genetics of organisms. By using gene-specific primers, a small single region in the huge genomic DNA is selectively amplified by PCR. Thus, PCR is quite frequently used for determination of gene alleles and to identify nucleotide sequences of genes. For these variety of analytical purposes, PCR method is often combined with the other DNA-related methods such as sequence-dependent DNA digestion with restriction enzymes, bisulfite reaction of genomic DNA for estimation of cytosine methylation, and usage of adaptor DNA for advanced analyses.

Peroxynitrite and Hypochlorite Fluorescence Quantification by S,N and P,Nco-Doped Carbon Dots

Eliana FC Simoes, Joaquim CG Esteves da Silva and Joao MM Leitao

Abstract

Carbon Dots (CDs) responding to Peroxynitrite (ONOO-) and Hypochlorite (ClO-) were synthesised by microwave methodology. To improve the quantum yield, selectivity an sensitivity, CDs were doped with Sulphur, Nitrogen and Phosphorous, Nitrogen (S,N-CDs/P,N-CDs) using urea, cysteine and sodium phosphate.

Plotting Colors on Color Circle: Interconversion between XYZ Values and RGB Color System

Ichiro Kasajima

Abstract

Color is generated by optical properties of the pigments. Colors can be calculated by using color matching functions. Color-measuring apparatus such as colorimeters and digital cameras also provide convenient ways to analyze object colors.
