What bad is there in when using Laser Printer?

I am using Laser Printer in the office and found that while printing, there's a smell coming out from the printer. Wondering whether it is good for health. i done a search through the net and this is what i found. (up to individual to believe)

The smells is classified into 3 things:

(a) mutagenic and/or carcinogenic compounds contained (and thereby released into the atmosphere) in the toner;

"Material Safety Data Sheets" from one particular Printer company. (i do not wish to name) These list under "hazardous ingredients" Ferrosoferricoxide, Styrene Acryic resin, "dye" and carbon black.

The toxicity of the oxide is described as zero. That of the resin as being rendered biologically inert by the polymerisation process. The "dye" is not discussed. Carbon black has been subject to toxicity and carcinogenic exposure experiments. One view is that while carbon black particulates contain some molecules of carcinogenic materials, the carcinogens areapparently held tightly and are not eluted by water, gastric juices orblood plasma.

Using a bacterial assay technique, extracts from several different photocopies were shown to be mutagenic. The evidence, they suggest, is that compounds in the toners used are responsible for this mutagenic activity.

(b) poisonous compounds on the drum; and

Not much on the drum compounds. Describes thepossible hazards associated with the use of photocopiers, and presentsrecommendations. Among subjects considered is the photoconductor (selenium).

(c) toxic gasses generated by the high electrical discharges involved.

Several people pointed to the dangers inherent in the production of ozone and oxygen radicals. Someone mentioned that the CaXXX LBP-8 engine uses a copper wool catalytic filter. Besides warning of the possible health hazards of chemicals used in toners (carbon black with aromatic polycyclic hydrocarbons and nitropyrenes,thermoplastic resins) and the evidence for mutagenic and carcinogeniceffects of these toners, also covers the effects of ozone, seleniumand organic solvents on health.

God Bless to all Office Worker and Users
