Module 1: Session 2
- This session covers aquatic microplastics, human exposure, human health risks, and ecological risks in aquatic ecosystems.
- Learning outcomes include understanding human exposure to aquatic microplastics, appreciating the human health risks, and appreciating the ecological risks.
Aquatic Microplastics and Human Exposure—Occurrence and Risk
- Human exposure to microplastics also happens through direct contact via personal care products like hand cleansers, facial/body scrubs, face masks, and toothpaste.
- Microplastics are found in tap water and significantly higher levels in bottled water.
- Microplastics transfer up the food chain to humans.
Aquatic Microplastics and Human Exposure—Occurrence and Risk
- Content of microplastics varies in tap water and bottled water.
- Microplastics have small sizes which means they are easily accumulated in aquatic organisms and terrestrial organisms, and they are transferred via food chain and end up in consumers.
- Microplastics present in food and drinks from different sources
Aquatic Microplastics and Human Exposure—Occurrence and Risk
- Microplastics in domestic food with microplastic additives range from 0.10 to 1.48 pieces per gram.
- People consume an average of 52,000 pieces per year from drinking and food. 121,000, counting inhalable MPs.
- The presence of microplastics is ubiquitous and inescapable, therefore humans are largely exposed in everyday environments and items.
Aquatic Microplastics and Human Exposure—Occurrence and Risk- Human Exposure Routes
- Exposure routes include ingestion, inhalation, and dermal penetration.
- Seafood is a notable source of ingested microplastics.
- Yearly consumption of microplastics per family unit is notable (e.g., mollusks , crustaceans, and fish).
Aquatic Microplastics and Human Exposure—Occurrence and Risk- Human Exposure Routes
- Microplastics are found in various types of salt. In water from groundwater sources.
- The size of microplastics in soft drinks, cold teas, and energy drinks is noticeable compared with other sources of microplastic.
Aquatic Microplastics and Human Exposure—Occurrence and Risk
- Factors that influence microplastic ingestion include direct release from food packaging and migration of chemical plasticizers from packaging to food.
- Size of microplastics in seafood (38.2-820 μm) and in canned seafood (up to 3800 μm).
Applied Microplastics and Human Exposure—Human Exposure Routes
- Microplastic particles can enter through the skin, passing through epidermal layers and reaching the microcirculation of the dermis.
- Microplastics are transported through the circulatory system.
Applied Microplastics and Human Exposure—Human Exposure Routes
- Dermal absorption often occurs when using personal care products such as hand cleansers, facial/body scrubs, face masks, and toothpastes.
- Large human skin area (1.5-2m²) makes exposure to ubiquitous MPs a concerning factor
Human Health Risks of Aquatic Microplastics- Toxic Chemical Additives
- Bisphenol A (BPA), phthalates, triclosan, bisphenone, organotins, and brominated flame retardants (BFR).
