My
mother-in-law was obsessive about the odor of air freshener. At any time when we
visited her, each toilet and bed room can be geared up with numerous sprays,
scents and room deodorizers. As soon as I woke up within the night time to one thing being
sprayed within the room. Within the morning, I discovered what it was: A brand new spray gadget
set to spritz air freshener into the room hourly.

However right here’s the factor: Aerosol
air fresheners contribute to, fairly than cut back, indoor air air pollution,
in response to the
Environmental Protection Agency (EPA). “Typically, the chemical substances that create the aerosol impact
are dangerous for the atmosphere, specifically the ozone,” says Stewart Lonky,
an professional in organic toxicity and writer of “Invisible
Killers: The Reality about Environmental Genocide.”

“Have you ever
learn the ingredient labels on most air fresheners?” asks Ok.B. Lee, founder and
CEO of Ever Bamboo, an organization that promotes pure methods to neutralize odors. Likelihood is you’d see perfume or
fragrance on the checklist, and that single ingredient might comprise as much as 400 extra components,
a few of them poisonous. Aerosol sprays additionally comprise chemical substances like formaldehyde and
xylene, so that you’re “freshening” with toxins.

“These components are carcinogens
and neurotoxins dangerous to our our bodies, youngsters and pets,” says Lee. There are
actual dangers, particularly with hair sprays and air fresheners, which might ship formaldehyde
and different risky natural compounds (VOCs) not solely into the air, but additionally
onto surfaces all through your own home.

“As soon as
on surfaces, these toxins can get in your fingers,” and from there, after all,
they will get into your mouth. Says Lonky. “This methodology of consumption is commonly extra
dangerous and ubiquitous than many individuals understand.” For instance, aerosol spray
paint could comprise methylene chloride, which is thought to trigger most cancers in animals,
in response to the
Consumer Product Safety Commission. And if you happen to ingest it, your physique converts it to carbon monoxide and may trigger signs related to carbon
monoxide publicity.

What aerosol
does to the atmosphere

Much more dismaying is how aerosols, that are tiny particles suspended in gasoline, are affecting the local weather. In accordance
to a
new MIT study printed in Geophysical
Analysis Letters, they could be altering rainfall. “Whereas it’s true that complete precipitation change is managed by
common world temperature change, … our analysis reveals that aerosols have
considerably impacted the distribution of precipitation change across the
world since preindustrial occasions,” stated Chien Wang, a senior analysis
scientist on the MIT Joint Program on the Science and Coverage of International Change
and the MIT Division of Earth, Atmospheric and Planetary Sciences.

NASA explains how aerosols can have an effect on the rain:

“Aerosols
are thought to suppress precipitation as a result of the particles lower the scale
of water droplets in clouds. Nonetheless, underneath some environmental circumstances,
aerosols can result in taller clouds which are extra prone to produce lightning
and robust downpours. In a couple of locations, meteorologists have even detected a
cycle wherein the frequency of thunderstorms is related to mid-week peaks in
aerosol emissions.”

Many individuals
affiliate aerosol sprays with damaging the ozone layer. However corporations
eradicated ozone-depleting chemical substances, also referred to as chlorofluorocarbons (CFC),
again within the ‘70s. Most aerosol merchandise made or bought within the U.S. now use
propellants — equivalent to hydrocarbons and compressed gases like nitrous oxide —
that don’t deplete the ozone layer.

Nonetheless,
that doesn’t make aerosols secure. Each
time you spritz an aerosol, you increase your carbon footprint as a result of they
comprise hydrocarbon and compressed gasses. In actual fact, at this time’s CFC-free aerosols
additionally emit VOCs that contribute to ground-level ozone ranges, a key cog in
asthma-inducing smog.

Lowering aerosol utilization

The EPA suggests avoiding aerosols when attainable. But when it’s important to use an aerosol
spray, they provide the following pointers:

  • Fastidiously estimate the
    quantity of product you should full a selected job and purchase solely that
    a lot. Keep away from “tremendous” sizes or bundled aerosol merchandise.
  • Skip merchandise which are
    sprayed instantly on the physique like sunscreen, hair spray and deodorant. Select
    non-spray choices, like lotions or a pump spritz, as an alternative.
  • Keep away from any spray-freshening
    product. Simply open your home windows to enhance air circulation and freshen
    indoor air.

Inexperienced disposal

If in case you have
empty aerosol cans, recycle punctured cans with scrap steel or in a separate neighborhood
program specified for aerosols. If the can held hazardous waste merchandise like
paint or solvents, or nonetheless has product left, it should be handled as hazardous
waste,
the EPA says. Contact your native waste administration workplace for extra data
on hazardous waste disposal in your space.
