Plastic Burning Particulate Matter as a Source of Environmentally Persistent Free Radicals and Reactive Oxygen and Chlorine Species
Опубликована: Фев. 26, 2025
Abstract
Burning
plastic
waste
releases
massive
amounts
of
atmospheric
particulate
matter
(PM),
but
its
chemical
composition
and
health-related
properties
are
largely
unelucidated.
Here
we
characterize
PM
generated
from
burning
common
types
plastics
quantify
reactive
oxygen/chlorine
species
oxidative
potential
(OP).
We
find
that
contains
high
levels
environmentally
persistent
free
radicals
(EPFRs),
transition
metals,
polycyclic
aromatic
hydrocarbons.
In
the
aqueous
phase,
generates
hydrogen
peroxide,
•OH
radicals,
carbon-centered
organic
exhibiting
OP
as
characterized
by
DTT
OH
assays.
Remarkably,
is
associated
with
concentrations
hypochlorous
acid.
Kinetic
model
simulations
demonstrate
respiratory
deposition
leads
to
formation
via
complex
redox
reactions
among
constituents
antioxidants
in
lung
lining
fluid.
Our
study
highlights
significant
health
implications
for
unregulated
burning,
particularly
many
areas
developing
countries.
