Description

Microplastics (MP) are pieces of plastic less than 5 micrometers (mm) and Nanoplastics (NP) are less than 1 micrometer (um). Microplastics are found in our environment and have even been found in the food humans consume, including in drinks from plastic bottles (Hu 2020).

•Permethrin is an artificial insecticide commonly used on crops, livestock and human application.

•Very little research on the effects of permethrin on human health has been conducted especially on the reproductive system.

•Permethrin is believed to be a human carcinogen with damage and inflammation being found in liver and kidneys (Sun 2022).

•Weuse C. elegansas a model organismto ask about combinedNP and permethrin exposure (Liu 2024).

•C. elegans is a widely excepted model organism for toxicology studies.

•Here we use C. elegans to investigate the physiological effects involved when organisms are exposed to both nanoplastics and permethrin.
