OBJECTIVE To determine the use of lead-based paint in public playgrounds in the municipalities of Johannesburg, Tshwane and Ekurhuleni. METHODS Forty-nine public parks were selected from the municipalities of Johannesburg, Tshwane and Ekurhuleni. Lead levels in paint on playground equipment were measured in situ using a hand-held Thermo Scientific NITON XLP 700 Series X-ray fluorescence (XRF)...

In spite of the availability of substitutes for lead compounds used in paints, manufacturers continue to produce these paints for decorative and industrial applications. We report here on the concentration of lead in new paint sold in Cameroon and provide a summary of labeling practices on paints available in the country, based on a market survey. Investigators visited 76 retail and wholesale p...

Microorganisms growing on painted surfaces are not only an aesthetic problem, but also actively contribute to the weathering and deterioration of materials. A widely used strategy to combat microbial colonization is the addition of biocides to the paint. However, ecotoxic, non-degradable biocides with a broad protection range are now prohibited in Europe, so the paint industry is considering en...

In this paper, we present a watercolor inspired method for the rendering of surfaces. Our approach mimics the watercolor process by building up an illuminated scene through the compositing of several layers of semitransparent paint. The key steps consist of creating textures for each layer using LIC of Perlin Noise, and then calculating the layer thickness distribution using an inverted subtrac...

A major source of childhood lead poisoning, still a serious problem in the United States, is paint. The dangers of lead were known even in the 19th century, and the particular dangers to children were documented in the English-language literature as early as 1904. During the first decades of the 20th century, many other countries banned or restricted the use of lead paint for interior painting....

A THESIS ON TECHNIQUES FOR NON-PHOTOREALISTIC SHADING USING REAL PAINT by Reynold J. Bailey ADVISOR: Professor Cindy Grimm May, 2004 Saint Louis, Missouri The goal of this research is to explore techniques for shading 3D computer generated models using scanned images of actual paint samples. The techniques presented emphasize artistic control of brush stroke texture and color. We first demonstr...

Automobiles, planes, ships, machinery, facades and the interior of buildings, furniture, household appliances, magazines, posters and data storage devices: The list of products covered with lacquers and paints is sheer endless. In 2012 about 2.6 million tons of lacquer, paint and printing ink were produced in Germany (VdL 2013). This shows how important these products are in our daily lives. Su...
