Cytochrome P450 monooxygenase specific activity reduction in wheat

Kangxin HE,Qixing ZHOU

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 2,   Pages 270-275 doi: 10.1007/s11783-015-0813-y

Abstract: Roxithromycin, as widely used medicine and livestock growth promoter, arouses concern because its occurrence and persistence in soil environments. However, effects of roxithromycin in higher plants are still vague. Accordingly, we hypothesized that roxithromycin-contaminated soil may exhibits ecotoxicological effects in wheat ( ). In this study, effects induced by a gradient concentration of roxithromycin stress (0.01, 0.1, 1, 10, and 100 mg·kg ) was investigated in a 7-d soil test in . Results indicated that the specific activity of cytochrome P450 (CYP450) monooxygenase was decreased dramatically with the concentration of roxithromycin in soil. The IC value was 8.78 mg·kg of roxithromycin. On the contrary, the growth related endpoints (i.e., the germination percentage, the biomass and the height), the content related endpoints (i.e., soluble protein content and CYP450 content), and the superoxide dismutase (SOD) activity failed to reveal the roxithromycin-induced effects. Further analysis revealed that the CYP450 monooxygenase specific activity reduction was enzymatic mechanism mediated, other than oxidative stress induced. We conclude that the soil roxithromycin declined the CYP450 monooxygenase activity in by the inhibition of the enzymatic mechanism. Further efforts can include, but are not limited to, investigation of joint effects induced by combined exposure of roxithromycin and the pesticides and evaluation of the similar effects in other higher plants.

Nanosized magnetite in low cost materials for remediation of water polluted with toxic metals, azo- and

María Fernanda HORST,Verónica LASSALLE,María Luján FERREIRA

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 5,   Pages 746-769 doi: 10.1007/s11783-015-0814-x

Abstract: Nanosized magnetite has emerged as an adsorbent of pollutants in water remediation. Nanoadsorbents include magnetic iron oxide and its modifiers/stabilizers, such as carbon, silica, clay, organic moieties (polymers, aminoacids, and fatty acids) and other inorganic oxides. This review is focused on the recent developments on the synthesis and use of magnetic nanoparticles and nanocomposites in the treatment of contaminated water. The emphasis is on the influence of the iron oxide modifiers on some properties of interest such as size, BET area, and magnetization. The characteristics of these nanomaterials are related to their ability to eliminate heavy metal ions and dyes from wastewater. Comparative analysis of the actual literature was performed aiming to present the magnetic material, its preparation methodology and performance in the elimination of the selected pollutants. Vast information has been properly summarized according to the materials, their properties and preferential affinity for selected contaminants. The mechanisms governing nanomaterial’s formation as well as the interactions with heavy metals and dyes have been carefully analyzed and associated to their efficiency.

fabricating photoluminescent carbon dots and its potential application as an efficient sensor probe for toxic

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 5,   Pages 536-547 doi: 10.1007/s11705-022-2239-y

Abstract: The past decade has witnessed a variety of members of the carbon family along with exposure of carbon dots due to their magnificent properties in sensing, bioimaging, catalytic applications, biomedical fields, and so on. Herein, we report the simple hydrothermal method to fabricate photoluminescent doped carbon quantum dots for the detection of noxious lead(II) ions. Lead(II) ion is very venomous for both the environment and human health for which its detection is demanded area in the research field. The as-prepared carbon dots show excellent photostability, low toxicity and significant photoluminescence properties along with good water solubility. Along with these properties, carbon dots have a quantum yield of approximately 15%. In the practical field of application, these carbon dots have been used as sensing probes for the detection of lead(II) ions with a detection limit of 60 nmol·L–1. The fluorescence intensity of carbon dots was remarkably quenched in the presence of the lead(II) ion selectively among all the tested metal ions. Furthermore, we have studied the Stern–Volmer relationship for lead(II) quenching along with the explanation of the probable quenching mechanism. Ability of the doped carbon dots in heavy metal ions sensing in an environmental sample was demonstrated.

Concentrations of toxic heavy metals in ambient particulate matter in an industrial area of northeastern

Frontiers of Medicine 2008, Volume 2, Issue 2,   Pages 207-210 doi: 10.1007/s11684-008-0040-z

Abstract: This paper investigates concentrations of various heavy metals in ambient particulate matter (PM) and provide evidence for prevention from air pollution. The concentrations of heavy metal components in the PM were determined by inductively coupled plasma/Mass spectrometry (ICP/MS) from September 2000 to August 2002 in a northeast industrial city in China. Concentrations of Cd, Mn, Pb, Ni, Cr and As in the PM were 9.3, 461.9, 588.7, 69.5, 205.7 and 57.4 ng/m in the industrial area, and 5.7, 245.5, 305.0, 31.4, 58.8 and 32.5 ng/m in the main road, respectively. Concentrations of these heavy metals except Cd were significantly higher in the industrial area and main road than those in the suburban area ( < 0.05 or < 0.01). The change curves of the six heavy metal concentrations show their concentrations increased in the winter and spring, but decreased in the summer and autumn. The results indicate that concentrations of the metals in the PM are relatively high in the industrial area and main road.
