Microplastic (Mps) and Nanoplastic)Exposure through inhalation

 

   Micro and aNano exposure     Through Inhalation

Inhalation is another significant route

 of human exposure to MNPs.(Micro and Nanoplastic )

The hypothesised sources of 

Airborne MPs are synthetic textiles,

 construction materials, road-wear particles,

 abrasions of plastic materials, landfills,

 sewage sludge, and waste incineration.^12,33, 34, 35 

MPs were found in indoor air, constituting 4% of indoor airborne particulates.³⁶

 It has been estimated that, on average,

 an individual inhales up to 130 MPs per day.¹²

 MPs can reach the human respiratory system and cause adverse health effects;

 industrial workers are more susceptible to exposure to MPs.^37,38 

Aerodynamic size is a defining factor in determining the depth of particle distribution within the airways once inhaled. 

The smaller the particle, the more likely it is 

to reach deeper lung regions. 

Inhaled particulate matter below

 2.5 microns in aerodynamic size is of

 concern due to the higher probability 

of reaching the alveolar sacs, where gas exchange and particle translocation from epithelial to endothelial cells occurs
