The stabilization and dispersion of titanium dioxide nanoparticles (TiO2 NP) in bivalves is a topic of increasing environmental and ecological significance due to the growing use of these particles in various industries and their inevitable release into aquatic environments. The focus of this review is to examine the current literature on this subject, identify gaps in knowledge, and propose directions for future research.
Titanium dioxide nanoparticles are a common component in many commercial products, including cosmetics, sunscreens, and consumer goods due to their unique optical and photocatalytic properties. However, this ubiquity also leads to the potential for widespread environmental exposure and bioaccumulation, especially in aquatic organisms such as bivalves.
Bivalves are an integral part of aquatic ecosystems, serving as both primary consumers and as biomonitors for environmental toxins due their ability to filter and accumulate pollutants from the water column. As such, understanding the effects of TiO2 NP in these organisms is critical for both ecological risk assessment and the development of nanoparticle waste management strategies.
In the existing literature, experimental protocols for the exposure of bivalves to TiO2 NP vary greatly, with the primary focus being on acute toxicity. Research has found that exposure can lead to physiological and biochemical changes in bivalves, including oxidative stress, inflammation, and DNA damage.
However, less attention has been paid to the processes of uptake, accumulation, excretion, and trophic transfer of TiO2 NP in bivalves. Also largely overlooked is the potential role of the nanoparticle’s physiochemical properties – such as size, shape, and surface coating – in mediating these processes.
Future research should aim to standardize experimental protocols and investigate these unknowns in order to establish a comprehensive understanding of the environmental and ecological implications of TiO2 NP exposure in bivalves. This could also potentially extend to other nanoparticles and aquatic organisms, contributing to the broader field of nanoecotoxicology.
Overall, the stabilization and dispersion of titanium dioxide nanoparticles in bivalves is an emerging area of study with significant implications for the environment. More rigorous and comprehensive research is needed to uncover the full extent of these impacts.
