However, this toxicity of photographic chemicals. book is not fulfilled if an aqueous lethal concentration (LC50) is used as T indicator because LC50 includes both bioconcentration and intrinsic by: toxicity of photographic chemicals. book   A large percentage of black and white darkroom chemicals are, when used at working strength, quite benign.

Even when concentrated, most black and white darkroom chemicals can be easily handled safely. None of the common darkroom chemicals should normally be swallowed, but that is the case with many household items. Toxicity. Toxic wastes are harmful or fatal when ingested or absorbed.

When toxic wastes are disposed of on land, contaminated liquid may drain (leach) from the waste and pollute ground water.

Toxicity is defined through a laboratory procedure called the Toxicity Characteristic Leaching Procedure (TLCP). Photographic processing or photographic development is the chemical means by which photographic film or paper is treated after photographic exposure to produce a negative or positive raphic processing transforms the latent image into a visible image, makes this permanent and renders it insensitive to light.

All processes based upon the gelatin-silver. Get this from a library. Health hazards for photographers.

Photgraphic Chemicals. Photographic chemicals generally fit into four categories: fixers, developers, rinses, and specialized chemicals. Standard developers and rinses can be rinsed down the drain during processing.

Most fixers contain silver in quantities above the amount allowed for sewer disposal.
