Abstract :
Zinc oxide (ZnO) nanoparticles are not a result
of the rising demand for sunscreens being introduced into
aquatic environments. However, their realistic behavior
and long-term exposure still need to be comprehended. A
practical and rapid method was employed in this study to
extract "ZnO nanoparticles" from sunscreen products
with "ZnO" bases that are sold in Australia, which were
then transported to wastewater. The "ZnO nanoparticles"
were separated and had a negative charge at a controlled
pH of 7. The TEM" assessment of nanoparticles separated
from sunscreens and wastewater revealed that these
aggregates had a size of around 100 nm and were
irregular, spherical, and rod-shaped. "Zinc oxide, iron,
silver, and titanium" were among the numerous
nanoparticles discovered in wastewater samples from
treatment facilities. Furthermore, based on TEM"
elemental analysis, additional pollutants were present in
the treated water samples. These results are useless in
comprehending the identification and characterization of
"ZnO nanoparticles" in sunscreens and wastewater. They,
therefore, cannot support a more accurate investigation of
their destiny, behavior, and negative impacts.
