“…However, the proline content in C. demersum, E. crassipes, H. verticillata, and S. cucullata increased when the atrazine concentration was increased. Increasing the proline content in the plant is another plant response mechanism to oxidative stress (Bibi et al, 2019) because proline can also act as an antioxidant molecule in plants (Din et al, 2020). Increased proline content has been reported in maize seedlings exposed to atrazine at 500 and 1,000 mg/L (Bibi et al, 2019).…”

“…The proline content of A. microphylla grown under atrazine contamination was higher than that grown under the non-contaminated condition. It was evident in the response of A. microphylla grown under 25 mg/L of atrazine, whereas proline acts as an antioxidant molecule that plants synthase in response to atrazine stress (Bibi et al, 2019). In addition, the phenolic and flavonoid contents in A. microphylla grown under atrazine-contaminated water without the plant growth regulator application did not significantly differ (P>0.05) from that with the plant growth regulator (6-benzyladenine, gibberellic acid, indole butyric acid, and salicylic acid) application (Table 2).…”

The extensive use of atrazine to control weeds in agricultural areas has contaminated atrazine in surface water and groundwater. Atrazine contamination in water resources causes human health concerns. Thus, this study investigated the possible use of aquatic plants for removing atrazine from contaminated water. The experiment was performed under plant nursery conditions and divided into two parts: (1) the atrazine-tolerant plants were screened, and (2) the most atrazine-tolerant plant was used for atrazine phytoremediation stimulated by plant growth regulators. The results showed that atrazine was toxic to all aquatic plants, as the dry weight of the plants was significantly decreased when exposed to 20 mg/L of atrazine (P<0.05). Based on five aquatic plants grown under 2.5–20 mg/L atrazine-contaminated water, Azolla microphylla Kaulf. was the most tolerant aquatic plant and was more suitable for use in atrazine phytoremediation than the other aquatic plants (Ceratophyllum demersum L., Eichhornia crassipes (Mart.) Solms, Hydrilla verticillata (L. f.) Royle, and Salvinia cucullata Roxb. ex Bory). The total chlorophyll, carotenoid, and proline contents in the biomass of A. microphylla cultured in 2.5–20 mg/L of atrazine did not significantly differ between the atrazine concentrations (P>0.05). Meanwhile, the proline contents in the other four aquatic plants increased with increasing atrazine concentrations, and the chlorophyll content significantly decreased with an increase in the atrazine concentration. However, A. microphylla could not remove atrazine from contaminated water, and the application of plant growth regulators (6-benzyladenine, gibberellic acid, indole-3-butyric acid, and salicylic acid) did not improve the atrazine removal from water. Atrazine in the water was around 21–26 mg/L on day five of A. microphylla cultivation compared to the initial concentration (25 mg/L). Using a plant growth regulator was ineffective for stimulating growth and atrazine removal by A. microphylla. Future research should explore other potential mechanisms for enhancing atrazine removal by A. microphylla.

“…Biochemical parameters could be used as important and sensitive biomarkers in ecotoxicological studies concerning the effect of metal contamination and fish health [9]. MgO nanoparticles are acutely toxic to aquatic ecosystems because of its accumulation and extensive use, posing a severe threat to the environment [10]. The haematological indicators are important for evaluating the physiological state of a fish.…”

Magnesium oxide nanoparticles were synthesized and characterized by using UV-Visible spectroscopy, SEM, XRD, EDAX, FTIR, and AAS. Toxicity tests were observed at 96 hours in different concentrations of magnesium oxide nanoparticles exposed in mrigal. The sub-lethal studies were conducted for 14 days. Biochemical and haematological parameters were estimated. The UV-Visible absorption spectra demonstrate that magnesium oxide nanoparticles were measured in the wavelength range of 200-1100. Morphological characteristics were observed by using SEM at the wavelength of 2µm. EDAX spectrum showed two peaks located between 0KeV to 10KeV. The peak at 1.2KeV comes from magnesium and the second peak at 0.3KeV indicates oxygen. XRD results confirmed the crystalline size of magnesium oxide nanoparticles and the approximate particle size is 10nm. The FT-IR spectrum was analysed at the wavenumber range of 400-4000cm-1and the functional groups are alcohols, alkaline, anhydride and sulfonate. Atomic absorption spectroscopies estimate the convergence of metallic components in magnesium oxide. Total protein and lipid content in the muscle, gill and liver of Mrigal is significantly increased and carbohydrate content decreased when reared in different magnesium oxide concentrations. All the blood parameters are gradually increased from lower concentration to higher concentration. In the DPPH assay, when hydrogen donating ability with the DPPH, the red colour turns to yellow colour. Hydroxyl radical scavenging assay showed that the polyunsaturated fatty acid moieties of cell damage in lower concentration compared to higher concentration.
