Nano-plastics may adversely affect the functioning of organs such as liver, kidneys and intestines, cause breast cancer and may also affect reproduction by interfering with reproductive hormones, especially in women.

Article Micro(nano)plastics: A threat to human health?
It is an interesting question.Thank you for sharing it. Unfortunately, I am not expert in this issue. But I am enthusiastic to learn about it by following this question and beneficial answers of RG members.
Because nanoparticles are very small, they can be carried out very easily through the skin, lungs and organs of the human without knowing their effect on human health. On the other hand, can inhalation of nanoparticles (such as nanoparticles, nanoparticles, carbon nanotubes, etc.) ..) will lead to the flow of these substances within the body and then access to the brain.
There are no specific regulations or laws that specify the damage and hazards resulting from the use of nanomaterials because of the different properties and sizes of these nanomaterials, as well as the degree of toxicity of those substances. There are currently not many experiments and research on the dangers of this technique except some research on experimental mice, And some experiments have suggested that inhaled nanoparticles can cause inflammation in the lungs more than large-scale particles of the same species. Another study suggested that nanoparticles caused the death of some rodents and brain damage in fish, Other studies on air pollution that increase the concentration of nanoparticles in the air will increase the spread of disease and death.
In general, nanotechnology workers must take all kinds of precautions to avoid inhalation of nanoparticles of all kinds or contact with human skin.
The nanoscale size of nanomaterials is meant to be more capable of being absorbed within the human body than large particles. The issue of how to deal with these nanoparticles within the human body is one of those issues that require a solution. The behavior of nanoparticles is the function of their size, shape and surface interaction with surrounding tissue.
Would assume that spilling of plastic results more in problems with microplastic. Reaching size of nano particles (means 100 nm or smaller at least in one dimension) there will be an enhanced rate of degradation. Do not know about results showing that plastic particles in environment contain a considerable mass fraction of nano particles.
Clearly, the highest risk of microplastic for humans is through ingestion. Likely most of particles taken up will leave the body. Unfortunately, we might see only after a few years, whether part of the particles will accumulate in various organs. In addition it has to be considered that particles will be covered with biofilm and that they are not only accumulate organic toxins but also bind them efficiently.
This is just the beginning of our understanding of the consequences of micro/nano-plastics in the environment and food chain (oxidative stress and DNA damage in the cells of marine life)... https://phys.org/news/2018-07-first-time-geneticphysiological-nanoplastics-mussels.html
New technologies are welcome. However process of recycling of any material produced after use by human, should be studied. Pollution taxes should be imposed on the users of the products, to make the nature pure by expending the amount collected by the governments.
This era is PLASTIC era. For convenience sake identified/discovered by human, we reached such a stage difficult to manage our routine life without plastics . These days everything is plastic right from the lunch box to spoon, carry bags, water bottle everything... everything. Check the following link they mentioned about them, 'the chemicals added to plastics to give them desirable properties, such as malleability, and the even tinier nanoplastics that microplastics presumably degrade into. Those might pass into the tissues of fish and humans.'
WE MADE PLASTIC. WE DEPEND ON IT. NOW WE’RE DROWNING IN IT.
