The FirstPost website reports that man-made nanomaterials (MNMs), used
in popular cosmetic products such as shampoos, gels, hair dyes and
sunscreens, may be affecting the quality and yield of the crops.
So women's hair growth products products could be safer for the environment as well as being good for your locks.
John Priester, environmental scientist at the Bren School of
Environmental Science and Management, University of California, Santa
Barbara, told the website: “As MNMs are used more and more in consumer
products, there is a higher likelihood that they will end up in
wastewater treatment facilities.”
The journal Proceedings of the National Academy of Sciences reported
that conventionally-treated wastewater is often added to agricultural
soil as fertilizer.
Priester and his research team examined what happened when they grew
soybean plants in soil amended with high-production nanomaterials.
They looked at the effects on plant growth by measuring stem length, leaf count and leaf cover.
They found high levels of zinc in the leaves and beans of plants exposed
to particular ZnO nanoparticles, and found that soil fertility was
affected by others.
The researchers wrote: “These results indicate broader risks to the food supply.”
Another good reason to use women's hair growth products!
