“…Ebdon[17] recommended a method using a finely powdered paint sample, 0.07 molar (pH 1.15) hydrochloric acid and a temperature of between 20 and 22°C – which is intended to approximate to the dissolving power of the human gastric juices. In this study digestion conditions were slightly modified in an attempt to simulate conditions in the human stomach more realistically.…”

Paint and dust samples were collected from a children′s nursery in a London school. After chemical digestion using an available lead extraction method, lead concentrations were determined by atomic absorption spectrophotometry. Most samples analysed were considered to pose no hazard to the children. However, a few samples contained available concentrations in excess of 2,500ppm and were considered potentially hazardous. Such high concentrations were thought to be due to remnants of old paint applied prior to the introduction of regulations to limit the content of lead in paint. Although the lead‐in‐paint hazard has diminished in recent years, the possibility of old lead paint still being a hazard should not be ignored.

A novel ion concentration in liquid detection measurement method is proposed. This new technique uses an improved low pass filter (LPF) photonic band gap (PBG) cell structure, which is laid out on board a printed circuit (PCB). This paper demonstrates how the method can be applied to measure the concentration of CuSO4 with the advantage of low cost. © 2003 Wiley Periodicals, Inc.
