\u201cMost people don\u2019t think about the fact that the creams and emollients that we smooth on our skin don\u2019t just stay on our skin. Our investigations have shown that substances including parabens, which are common additives in skin creams and other cosmetic products, can be detected in blood samples shortly after you have used them. If these substances are found in your blood, that means they are also in your liver and other places in your body,\u201d says Torkjel Sandanger, a senior researcher at NILU.<\/p>\n
Norwegians spend more money on creams, deodorants and shampoos than ever before, and many of these products contain chemical substances that are potential pollutants. D2, a weekend magazine published by Dagens N\u00e6ringsliv, a Norwegian financial newspaper, invited the Norwegian comedian and TV personality Sigrid Bonde Tusvik, along with yoga instructor and program manager Vibeke Klemetsen to participate in a comparison of blood samples, in cooperation with NILU. Tusvik uses quite a few cosmetics and dabs them on, while Klemetsen carefully reads product labels and tries to select cosmetics that don\u2019t contain the questionable chemicals.<\/p>\n
\u201cWe found methyl- and propylparabens in the blood of both candidates, but the highest levels by far were in Bonde Tusvik,\u201d Sandanger told D2 after the blood samples were analysed. NILU also tested an anonymous third party who does not use cosmetics, and there were no measurable amounts of parabens in that individual\u2019s blood.<\/p>\n
\u201cWe humans are exposed to thousands of chemicals every day, and the basic idea should be that we do not need more chemicals in our bodies. Today, researchers must prove that a substance is likely to be dangerous before the authorities can ban it, but it would be better to use the precautionary principle. We know so little about how each substance affects the body and the environment, but we know even less about how many different substances interact with each other,\u201d said Sandanger.<\/p>\n
Sandanger is very careful with his own use of skin care products and usually studies the label before he buys a new product. \u201cEvery Day Green, a Norwegian environmental organization, has investigated many products and has made a list of what these products contain,\u201d he says, suggesting that consumers use the list as a resource.<\/p>\n
It has been difficult to determine whether parabens can cause cancer or hormonal disorders in humans, but in 2010 NILU scientists took a big step forward when they analysed blood samples from the \u201cWomen and Cancer\u201d study, led by Professor Eiliv Lund at the University of Troms\u00f8.<\/p>\n
Professor Lund has collected data and questionnaires from more than 70 000 Norwegian women.\u00a0 In 2010, NILU scientists analysed blood samples from 350 of these women and compared their findings with the women\u2019s own reports on their use of skin cream and other skin care products. \u201cWe found a clear correlation between self-reported use and the levels of parabens in the blood. The full results of this survey will be published in 2011,\u201d Sandanger says.<\/p>\n
NILU scientists are also concerned about methylsiloxanes, which postdoc Nicholas Warner found in the fjord outside of Longyearbyen in the arctic archipelago of Svalbard in 2010. \u201cWe also found siloxanes in Kongsfjorden outside of Ny-\u00c5lesund, and low levels in the remote Liefdefjorden on the northwest coast of Svalbard,\u201d Warner says. These results were published in the journal Environmental Science & Technology.<\/p>\n
\u201cCommunities in Longyearbyen and Ny-\u00c5lesund seem to be point sources, while it is difficult to say where the siloxanes in Liefdefjorden are coming from. It may be that fish have swum there from more contaminated areas, or that there have been discharges from cruise ships in the area,\u201d said Warner.<\/p>\n
Manufacturers have already phased out what are called D4 siloxanes, after studies suggested they had a toxic effect on marine life. \u201cProducers have shifted more to D5 and D6 siloxanes, which so far do not have any documented toxic effect. The main focus now is to investigate whether these substances accumulate in the environment. If we can show that they accumulate, we can go back to the toxicologists and check to see if they have any toxic effect. There seems to be a low risk of accumulation of methylsiloxanes in mammals, but there is reason for concern when it comes to fish and other aquatic organisms,\u201d Warner says.<\/p>\n
