Abstract Glyphosate, widely used herbicide, is considered harmful to the environment and human health. Its effects on growth rate and genotoxicity of Ipomoea aquatica were assessed in this work. The plants were grown in the soil which supplemented with glyphosate at 1- to 3-fold the recommended dose. After 30 days, lengths and dry weights of the roots and shoots were found to decrease in a concentration-dependent

Zinc oxide nanoparticles induce oxidative stress and histopathological toxicity in the thyroid gland and liver of rats Toxicol. Environ. Chem. (IF 1.8) Pub Date : 2021-06-30 Samar Sakr, Vanessa Steenkamp
Abstract Zinc oxide nanoparticles are incorporated into cosmetics and sunscreens and are widely used in biomedical applications and the food industry. The increasing use of zinc oxide nanoparticles raises concerns about their safety. The aim of the study was to assess the effects of zinc oxide nanoparticles on oxidative and genotoxic parameters in the thyroid gland and liver of adult albino rats. Rats

A review exploring the adsorptive removal of organic micropollutants on tailored hierarchical carbon nanotubes Toxicol. Environ. Chem. (IF 1.8) Pub Date : 2021-06-06 Haiyam Mohammed Alayan, Mustafa Mohammed Aljumaily, Mohammed Abdulhakim Alsaadi, Farouq Sabri Mjalli, Mohd Ali Hashim
Abstract Compared to other existing carbon nanomaterials (CNMs), carbon nanotubes (CNTs) are recognized for their significant properties. Despite their strong adsorption affinity, the difficulty of their dispersion and separation leads to limit their application in practical water treatment. Moreover, wastewater contamination by noxious organics, such as bisphenol A (BPA) and methylene blue (MB) dye

Interaction of copper (II) oxide nanoparticles with aquatic organisms: uptake, accumulation, and toxicity Toxicol. Environ. Chem. (IF 1.8) Pub Date : 2021-05-21 Gulen Oytun Akalin
Abstract Nanoparticles are used for several commercial applications, especially medical applications, energy-based research, and environmental applications. The usage of nanoparticles is increasing worldwide due to their unique properties, so all livings are exposed to these materials deliberately or unknowingly. The toxic nanoparticles disrupt the ecological balance of environment. The accumulation

Evaluation of stress factor on wheat (Triticum aestivum): the effect of ZnO and Ni-doped ZnO nanoparticles Toxicol. Environ. Chem. (IF 1.8) Pub Date : 2021-05-14 Zeynep Görkem Doğaroğlu, Fatma Ece, Buşra Nur Çiftci, Saadet Yıldırımcan, Selma Erat
Abstract Phytotoxicological evaluation of ZnO nanoparticles (NPs) is important to determine the possible effects on ecosystems. Although bulk Zn2+ ions can be used by plants as an essential micronutrient, it has many adverse effects on living organisms in nano-size. In this study, the growth, the development, and the stress effects of ZnO and Ni-doped (5%) ZnO NPs on wheat (Triticum aestivum – İkizce

Green synthesis of 1,7-bis(substituted phenyl)1,6-heptadiene-3,5-diones and their inhibition of human pathogenic bacteria Toxicol. Environ. Chem. (IF 1.8) Pub Date : 2021-05-03 Pudi Manga Veni, Padma Suhasini, Kilaru
Abstract Curcumin analogs are synthesized with solid support under the concept of green chemistry, i.e. in the absence of organic solvents or hazardous chemicals using silica-sulfuric acid under solvent free conditions. Their structures are established through infrared, NMR, and mass spectroscopy and elemental analysis. The antibacterial activities of the synthesized curcumin analogs are evaluated

Optimization of QuEChERS extraction of steroid hormones from infant formulae for mass spectrometric analysis Toxicol. Environ. Chem. (IF 1.8) Pub Date : 2021-03-11 Alireza Nezami, Bahram Daraei, Kamal razavi-Azarkhiavi, Maryam Amirahmadi, Javad Feizy, A. Wallace Hayes, John P. Giesy, Gholamreza Karimi
Abstract A rapid, simple and accurate extraction QuEChERS method was used for simultaneous determination of 22 hormones with a wide range of polarities in 35 infant formulae by use of LC–ESI-MS/MS. In the present method, some changes were made compared to other methods, which include eliminating the enzymatic hydrolysis step, derivatization and performing analysis a wide range of analytes with different

Immobilization of visible-light-driven photocatalyst g-C3N4 on ceramic fiber for degradation of organic dye Toxicol. Environ. Chem. (IF 1.8) Pub Date : 2021-02-11 Jeonghyun Hong, Jisue Kim, Rengaraj Selvaraj, Younghun Kim
Abstract In the case of wastewater treatment, many researche’s are mainly focused on nanopowder-type photocatalysts that have high efficiency because of their good dispersibility and high specific surface area. Ironically, these properties of nanopowder photocatalysts cause some drawbacks in their recovery from treated water, making practical applications in wastewater treatment difficult. The use
