“…In the current study, the occurrence of stickiness after SDFs exposure may be a response to the toxicity of chemicals in SDFs, which may lead to the depolymerization or degradation of chromosomal DNA, or condensation of DNA, and/or a function failure of non-histone chromosomal proteins [57,58]. This can also be explained as the physical adhesion of the chromosomal proteins [59]. In addition to stickiness, we observed a significant increase in chromosome bridges, which could be related to chromatin dysfunction.…”

The use of drilling waste for land reclamation is a cost-effective way to improve soil fertility and to decrease landfills. However, the potential phytotoxic and cytotoxic effects of this waste on crops have not been investigated in detail. Here, we evaluated the toxicity of spent drilling fluids (SDFs) from a natural gas field using the non-target plant Zea mays L. (maize). Four different concentrations of SDFs (2%, 4%, 6%, and 8%, w/w) were used to test the toxic effects in two soils (aeolian and loessal). Different endpoints, including germination, root elongation, reactive oxygen species (ROS) accumulation, antioxidant activity, mitotic index, and chromosomal abnormalities, were used to test the effects of SDFs after four days of exposure. Higher levels (≥6%) of SDFs inhibited seed germination and root growth, and altered the oxygen status by increasing hydrogen peroxide (H2O2) and inhibiting superoxide ion (O2−) accumulation in the roots. SDFs-induced oxidative stress caused member damage, exacerbated cell injury, and reduced cell viability in the roots, compared with those untreated plants. The plants responded to high SDFs levels (≥6%) by upregulating antioxidants such as peroxidase, superoxide dismutase ascorbate peroxidase, and proline. A reduction in the mitotic index and induction of chromosomal abnormalities in root meristematic cells were indicators of the cytotoxicity of SDFs in maize seedlings. The upregulation of antioxidants due to the change of ROS and the induction of chromosomal abnormalities were more severe in roots grown in aeolian soil than in those grown in loessal soil. The present results provide insight into the mechanism underlying the phytotoxicity and cytotoxicity of SDFs and have implications for land reclamation to minimize deleterious effects on non-target crops.

“…Chromosome loss (Figure 3h, j, n) and the lagging segregation (Figure 3o) typically alterations associated to the malfunction of the mitotic spindle [27]. Indiate to stickiness (Figure 3f), which is considered to be a physiological effect caused by the affected proteins of the chromosome, might cause daughter chromosomes not to be completely separated by the cross-linking of chromoproteins [28]. Ring chromosome (Figure 3c) is one consequence of chromosome losses in the telomer domain [29].…”

In this study, β-alanine effects on the seedling growth (radicle number, radicle length and fresh weight), seed germination, chromosomal aberrations, mitotic activity and micronucleus frequency in Allium cepa L. germinated in both salt stress and normal conditions investigated. In only β-alanine medium, the fresh weight, radicle number and radicle length of the seeds partially reduced compared to the control seeds germinated in distilled water medium but the germination percentage indicate statistically the same value as the control. Besides, while the micronucleus formation and mitotic index in root tip meristems of A. cepa seeds germinated in alone β-alanine medium showed the same values as the control seeds germinated in distilled water medium, the chromosomal abnormalities exhibited an increase compared to the control. On the other hand, salt stress significantly inhibited the seedling growth and seed germination of A. cepa. What"s more, it majorly reduced the mitotic index in meristem cells of the seeds and increased the number of chromosomal abnormalities and micronuclei formation, which is the simplest indicator and the most effective of cytological damage. Althought the harmful affects of saltness on the chromosomal aberrations, seed germination, seedling growth and mitotic activity alleviated in varying degrees by β-alanine treatment, this application was inefficient in damage reducing of salt on the micronucleus formation.

“…Sulcotrione is a well-recognized triketone “eco-friendly” herbicide that is used on wide-leafed agricultural plants. However, recent reports on the possible health and environmental effects problematize their use and require systematic monitoring [ 14 , 15 ]. Quality control of herbicide content in distributed food requires prompt, accurate methods for its quantification.…”

Stable, water-soluble titanium complexed with mandelic acid was used as a precursor for titanium phosphorus double oxide obtained in hydrothermal conditions in the presence of phosphoric acid. Surprisingly, hydrolysis of organic complexes provided a microstructured sphere with narrow size distribution, low aggregation and a small fraction of morphological irregularities. Obtained microspheres had a complex structure comprised of flakes, whose size could be manipulated with temperature conditions. Samples were found to be electrochemically active against sulcotrione, a well-recognized herbicide. Electrochemical sensors based on the synthesized microspheres were successfully adapted for natural water reservoir analysis and exhibited low levels of detection of 0.61 µM, limit of quantification of 1.86 µM, wide dynamic linear range from 2 to 200 µM, good selectivity, excellent reproducibility and in-time stability.
