Acute Toxicity of TiO2 Nanoparticles to Ceriodaphnia dubia under Visible Light and Dark Conditions in a Freshwater System

The ever increasing industrial and consumer applications of titanium dioxide nanoparticles (TiO2 NPs) raise concern over the possible risk associated with their environmental exposure. Still, the knowledge regarding nanoparticle behavior in a freshwater ecosystem is lacking. The current study focuses on the toxicity of TiO2 NPs towards Ceriodaphnia dubia (a dominant daphnid isolated from the freshwater) under two different conditions; (1) light and dark photoperiod (16:8 h) and (2) continuous dark conditions, for a period of 48 h. An increase in toxicity was observed with an increase in the concentration, until a certain threshold level (under both photoperiod and dark conditions), and beyond which, reduction was noted. The decrease in toxicity would have resulted from the aggregation and settling of NPs, making them less bioavailable. The oxidative stress was one of the major contributors towards cytotoxicity under both photoperiod and dark conditions. The slow depuration of TiO2 NPs under the photoperiod conditions confirmed a higher NP bioaccumulation and thus a higher bioconcentration factor (BCF) compared to dark conditions. The transmission electron micrographs confirmed the bioaccumulation of NPs and damage of tissues in the gut lining.

“…The results are in agreement with those obtained by Mendonç a et al [19], where a chronic toxicity test in D. magna exposed to NDs showed 100% mortality at concentrations higher than 12.5 mg l −1 and reproduction inhibited at concentrations higher than 1.3 mg l −1 .…”

“…Moreover, LPO results are supported by the histological observations that revealed the putative presence and accumulation of NDs in tissues, but also the alterations in the digestive gland cells such as degeneration, vacuolization, or thickening of the digestive gland cells. A study from Mendonç a et al [19] showed that Daphnia sp. exposed to different concentrations of NDs accumulated clumps of nanoparticles in organismís gut lumen but not inside cells.…”

“…Nonetheless, the result of releasing NDs into aquatic ecosystems and their effects on biota are largely unknown [19]. Consequently, the expected increase in the use of large quantities of nanomaterials highlights the discussion on environmental risk assessment, since aquatic ecosystems are generally the fate of discharges of industrial wastewaters [4,20,21].…”

“…The freshwater crustaceans like Daphnia and Ceriodaphnia are bioindicators and an extremely important member in aquatic ecosystems and has been used to determine the toxicity of chemicals or nanoparticles. They interact with large portions of the environment and therefore have a greater potential to be affected by ingestion of pollutant particulates compared to that of other aquatic organisms [16].…”
