“…Silver (Ag) has been used by humans for millennia; not only as a precious metal and symbol of wealth, but also in applications as diverse as sanitation (Oyanedel-Craver and Smith, 2008), photography (Bergthaller, 1996), industrial catalysis (Serafin et al, 1998), dentistry (Lorenz et al, 2012), and healthcare (Sambhy et al, 2006;Silver, 2003). In recent decades, efforts to reduce environmental pollution have brought about numerous resource recovery and effluent treatment guidelines and discharge limits; including some which specifically target key Ag emitting industries such as the photographic sector (e.g.…”

Increasing commercial use of nanosilver has focussed attention on the fate of silver (Ag) in the wastewater release pathway. This paper reports the speciation and lability of Ag in archived, stockpiled, and contemporary biosolids from the UK, USA and Australia, and indicates that biosolids Ag concentrations have decreased significantly over recent decades. XANES revealed the importance of reduced-sulfur binding environments for Ag speciation in materials ranging from freshly produced sludge to biosolids weathered under ambient environmental conditions for more than 50 years. Isotopic dilution with (110 m)Ag showed that Ag was predominantly non-labile in both fresh and aged biosolids (13.7% mean lability), with E-values ranging from 0.3 to 60 mg/kg and 5 mM CaNO3 extractable Ag from 1.2 to 609 μg/kg (0.002-3.4% of the total Ag). This study indicates that at the time of soil application, biosolids Ag will be predominantly Ag-sulfides and characterised by low isotopic lability.

“…There are basically three processes for obtaining colour photographs [6,7]:-1. by a dye-forming process. 2. by a dye-bleaching process (Cibachrome/Ilfochrome), and 3. by a dye-diffusion process (Polaroid).…”

“…The dye-forming process [6,7] In this chromogenic process the dyes are formed in proportion to the amount of photosensitised silver halide present in the film emulsion. The photosensitised silver halide contains the latent image and this must first be developed to produce the true image for subsequent viewing.…”

Digital photography was discovered by Sony in 1981. The technology struggled for many years, mainly because the electronics of the day were inadequate. Nowadays, digital photography is the mainstream photographic technology, having overtaken the mature silver halide technology. This paper describes the chemistry and technology of silver halide and digital photography. Particular emphasis is given to producing high-quality images by ink jet printing, the technology of choice to produce photographic prints from digital cameras. r
