Environmental Commentary by Liza Field
After decades, my friend Mr. Crigger has abandoned his old foot-worn fishing spot along the river that bottoms our mountain watershed.
He quit not because the catch, even combined with his grandsons, kept decreasing. They didnt go there mainly for fish, but love of the river, its birds and sycamore shade and sweet old mineral vapors.
But today, the river often smells of perfumethe strong stuff used in dish soap, shampoo and laundry products.
These fragrances along Mr. Criggers old sandbar increasingly fumigate many U.S. rivers. They flow from shower drains, washing machines and sinks, via water treatment plants that remove sewage but not synthetic perfumes.
Mr. Crigger points out that he isnt persnickety. His Depression era childhood entailed hog slaughters, lye soap and no plumbing but an outhouse and spring.
He relishes real smells of bottomland, silage, even the cow manure he gathers by hand for his gardenbut not a river emanating the fumigants of a chemical porta-john. Nobody wants to eat a fish coming out of a smell like that.
Well, something is fishy about a deodorized river.. But synthetic perfume is now everywherewere all steeped in it.
Powerful contrails of floral-flea-bomb and sweet-artificial-grape billow from the most unlikely sourcesgarbage bags, kitty litter, truck cabs, bake sale cookies and diapered babies. Even the family dog smells embalmed with fabric softener.
Wheres it all coming from?
Todays artificial fragrance (synthetic musk) is mostly petroleum derived. Its why that greasy stick of Fresh Spring Breeze has rank undertones of epoxy, the cloying sweetness of nail-polish remover, benzene, acetones, nose-buzzing solvent.
Petrochemical VOCs (volatile organic compounds) are widely regulated in the discharge of other industries, but not the fragrance industry. It remains exempt even from ingredient disclosure, despite the accumulating presence of these products coming out in the wash of our environment.
But researchers analyzing these fragrances have found numerous toxic components.
These include hormone-disrupting phthalates, ethyl and butyl acetates (linked to liver and kidney damage), the carcinogens acetaldehyde and benzene, benzyl acetate (linked to pancreatic cancer and absorbed through skin), and central nervous system damagers like A-Terpineol, ethanol, toluene, pentane and linalool.
Perhaps thats why 13 percent of the population is now diagnosed with Multiple Chemical Sensitivity, their freedom literally lost to our common saturation in chemical fragrances.
Thirty percent of the population also considers these powerful VOCs irritating, and 20 percent report physical reactions to air fresheners, according to research surveys by Anne Steinmann at University of Washington, whose team has extensively analyzed these products.
Toxic fragrance VOCs are now found in human breast milk and adipose tissueeven the umbilical cord blood of newborns.
Howd this poison become so ubiquitous?
Synthetic musks can be easily produced and are very cheap, said Stanford researcher Till Luckenbach.
Hes one of many biologists concerned about the effects of these perfumes on waterways and marine ecosystems, where they end up.
Not only are petrochemicals cheap, they potentiate that odor-masking, nose-numbing power the industry esteems in its productspersistence.
And persistent they arenot least in the environment, where they do more than smell bizarre.
In water bodies from the Great Lakes to China to Germany, studies document the bioaccumulation of galaxolide and tonalideboth endocrine-disrupting fragrance components.
In aquatic systems, these compounds bind to sediment, harming the organisms that feed off it.
Stanford researchers Luckenbach and biologist David Epel studied the effects of six common perfume compounds on California mussels, and found that the fragrance chemicals compromised the mussels cellular defense equipmentthe xenobiotic defense systemwhich eliminates toxins.
Mussels impaired by fragrance compounds are thus left exposed to whatever other toxins come down the pike.
So may be humans, the study implies. We have similar xenobiotic defense equipment, not least in the blood-brain barrier tasked with keeping toxins from deranging our mental function.
Perhaps were already deranged.
Congress has defeated past bills calling for fragrance ingredient disclosure. The smell of money is a neurotoxin of its own, and petrochemicals fund many a political career.
But why should the average consumer help fund this pollution stream?
Its easy enough to buy only products that disclose all ingredients, and to houseclean with older effective scrubbers like baking soda, vinegar and fresh air (the real kind).
We can also go fragrance-free to respect that 13 percent afflicted with MCS. Perhaps their sensitivity to poison isnt abnormal, after all, but a gift of common sense to a species that appears to be losing ours.
