A recent study reveals microplastics are accumulating in the lungs of birds, marking the first evidence of this phenomenon. Researchers, led by Prof Yongjie Wu, analyzed birds from 51 species that were part of a program to prevent bird strikes at a Chinese airport. Every bird's lungs contained microplastics, averaging 416 particles per gram of lung tissue. Terrestrial and larger birds exhibited higher contamination levels, suggesting their feeding habits and exposure routes contribute to this issue, which highlights the ecological risks posed by airborne plastic pollution.
Microplastics were found in every bird's lungs, with an average of 416 particles in every gram of lung tissue. This highlights their role as bioindicators for pollution.
The widespread contamination across all sampled species, regardless of size or habitat, showcases a significant environmental concern and the urgent need for further research.
