The photodegradation of CEC using semiconductors such as TiO2 and ZnO nanoparticles (Chen et al., 2019; has been widely studied, but single-crystalline semiconductor photocatalysts cannot provide fast degradation kinetics Li et al., 2022). The activation of IO4 -has been reported using methods such as ultraviolet, ultrasonic irradiation, freezing, and microwaves. The azo dyes of chromium complexes damage the growth and development of plants (Lellis et al. 2019). The UV or chlorination process is efficient in degrading dyes from the wastewater, but it has not been executed in water bodies like ponds and lakes (Nikravesh et al. 2020). The toxic effects of dyes can be observed in aquatic animals like Xenopus laevis and Danio rerio and can cause developmental stages and embryonic damages, respectively.

A comprehensive body of literature exists to characterize the absorption, distribution, metabolism and excretion of trichloroethylene in humans and in experimental animals; it is clear that qualitative similarities are evident between humans and rodents. Two major metabolic pathways of trichloroethylene have been characterized in humans and laboratory animals. The major pathway is cytochrome P450 -mediated oxidation, resulting in formation of a variety of short- and long-lived metabolites. Subsequent processing of oxidative metabolites involves alcohol and aldehyde dehydrogenases and glucuronidation. In all species, trichloroacetic acid and trichloroethanol/trichloroethanol glucuronide are measured in vastly larger amounts than other oxidative metabolites.

ATL degradation could be described by the pseudo-first-order reaction kinetics. Combination of UV-254 nm and 100 μM of chlorine at pH 7 demonstrated 93.5% removal of 10 μM of ATL within 20 min. Radical scavenging tests indicated that both hydroxyl radicals and reactive chlorine species participated in ATL degradation by UV/chlorine. The highest degradation rate was achieved at acidic pH. The contribution of RCS towards ATL degradation elevated as pH value increased. ATL degradation rate constant directly correlated with chlorine dosage in the 0–100 μM range. Scavenging effect of the excess chlorine occurred above 200 μM.

Exposure to trichloroethylene was ascertained from the urinary concentrations of total trichloro-compounds, and subjects were divided into groups with low, moderate, and high exposure. Slight, but not statistically significant, increases in total and HDL cholesterol were observed with increasing exposure levels. No effect was found on the activities of the serum enzymes. In the follow-up study, concurrent fluctuations in urinary concentrations is the washington youth summit on the environment legit of total trichloro-compounds and subclinical (e.g. not exceeding the normal range in this study) changes in HDL cholesterol, AST, and GGT were observed. While there was some evidence for liver toxicity of trichloroethylene in occupationally exposed individuals, these effects were subclinical and reversible. Studies both in vitro and in vivo indicated that exposure to trichloroethylene can induce micronucleus formation.
