TOXIC SUBSTANCES IN OUR EVERY-DAY LIFE
• Chemicals – where do they come from?
• Effect on humans
• The PCB-story has restarted
MORE THAN 100 000 CHEMICAL SUBSTANCES ARE NOW IN USE IN DIFFERENT PRODUCTS
BASED ON NATURAL RAWMATERIALS THE INDUSTRY HAS DEVELOPED NEW CHEMICALS
CHEMICALS IN TEXSTILES
• Antibacterial agents
• Anti-mould agents
• Dyes
• Flame retardents
• Softeners
• Impregnation agents
• Anti-fouling biocides
Triclosan, nano-silver Dimethylforamide Azo-dyes Brominated flame retardents Phtataltes Perflurcompounds Organotin compounds
TOXIC SUBSTANCES IN OUR EVERY-DAY LIFE

PCB-molekyl
17β-Østrogen
Thyroksin
• PCB
• Bisfenol A
• Ftalater
• DDT
• Parabener
• Nonylphenol
Some substances have hormone like properties
MINAMATA BAY IN JAPAN – CHISSO CORPORATION
WASTE WATER CONTAINING METHYL-MERCURY WERE SEND INTO THE MINAMATA BAYBAY
CHEMICAL POISONING
• Release of methyl mercury in the industrial waste water from Chissco Corperation's chemical factory
• 1784 people died and 9 000 were invalidisert's
BHOPAL- DISASTER IN 1984
A cloud of methyl isocyanate gas leaked fromtheUnion Carbide pesticide plant
BHOPAL- DISASTER IN 1984
Up to10 000 in the first three days
Additional 25 000 died of related injuries by 1994

pregnancy outcome predictors
What is the cocktail effect?
Some medical researchers have observed reduced male fertility during the last 30 years
TOXIC SUBSTANCES IN OUR EVERY-DAY LIFE
• Chemicals – where do they come from?
• Effect on humans
• The PCB-story has restarted
POLYCHLORINATED BIPHENYLS (PCB)
• Production started in 1929
• No production in Norway
• 1100 tons imported as additive to transformer - and capasitors oil - paint, windows, sealants, plaster, concrete and plastics
ORGANIC PIGMENTS (PCBS DETECTED)
• Norwegian paints contain azo- and ftalocyanin pigments produced by CPS Color in Finland
• Mono PCB: 2,05 mg/kg
• Di PCB: 3,7 mg/kg
• The total PCB containt is not known
MODERN PRODUCTION OF PCB
• PCBs are produced as byproducts during the production of commonly used organic pigments.
• Their presence in common consumer products may dominate current sources to the environment
