Micro and Nanoplastics in Greenhouse Workers: Biomarkers of Exposure and Effect
Study Details
Study Description
Brief Summary
MNPLs effects on human health are still preliminary. Workers exposed to plastic residues are exposed constantly to MNPLs. One of these jobs corresponds to greenhouse workers, that could be considered as a population highly exposed to plastics. The objective of the research is to be able to detect MNPLs on body fluids as well as their potential genotoxic and immunological damage.

Detailed Description
The exponential increase in the production/use of plastic translates into a parallel increase of environmental plastic waste that is continuously degraded into MNPLs. Information on the MNPLs' effects on human health is still preliminary and, furthermore, the limitations in current methodologies prevent accurate exposure/risk assessment.
This observational study will obtain body samples of greenhouse workers and from a control group. That would allow optimizing specific biomarkers of human MNPLs exposure and the characterization of biomarkers of early effect that allows an association among the exposure to MNPLs and effects on human health.
