Tetracycline (TC) antibiotics are one of the class of drugs widely used in clinical practice but also constitute a significant environmental concern. However, the adverse effects of TC on non-target organisms have not been well studied. The aim of this study was to examine the influence of exposure to high levels of TC on thalli of lichens to determine the impact on (1) physiological parameters including integrity of cell membranes, photosynthetic efficiency and viability, (2) oxidative stress response such as membrane lipid peroxidation, and (3) enzymatic antioxidant activities as catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX), and glutathione reductase (GR).

This study evaluated the short-term and long-term effects of tetracycline (TC), ciprofloxacin (CIP) and sulfamethoxazole (SMX) (1-500 mg kg) on earthworm Dendrobaena veneta by measuring multiple parameters (survival, growth, reproduction, behavior and biochemical responses). Neither antibiotic induced acute toxicity and low mortality was observed after chronic exposure.

The common plant response to exposure to vastly different stressors is the generation of reactive oxygen species (ROS) followed by activation of the defensive antioxidant system. We aimed to evaluate whether seed treatment with physical stressors can activate the activity of antioxidant enzymes and radical scavenging activity in young (L.

Therefore, this study aimed to compare the phytotoxic effects of veterinary antibiotics tetracycline (TC) and ciprofloxacin (CIP) applied in a wide range of concentrations on model plant oilseed rape (Brassica napus). Overall phytotoxicity of 1-500 mg kg of TC and CIP was investigated based on morphological, biochemical, and physiological plant response.

We applied an electromagnetic field (EMF) seed treatment to observe changes in the establishment and content of biochemical compounds in silver birch seedlings induced by a short (1 min) seed exposure to a physical stressor. The impact of EMF treatment was evaluated on seedling emergence and growth of one-year-old and two-year-old seedlings from seven half-sib families of silver birch.

Emerging pollutants and climate change are two main challenges affecting soil organisms today. Changes in temperature and soil moisture with climate change are key factors determining activity and fitness of soil dwelling organisms. The occurrence and toxicity of antimicrobial agent triclosan (TCS) in terrestrial environment is of high concern, while no data are available on TCS toxicity changes to terrestrial organisms under global climate change.

The aim of the study was to examine the influence of single elevated CO (400 vs. 800 ppm) and elevated CO in combination with temperature (21 °C vs.

The study aimed at determining the response of adult Eisenia fetida earthworms to chronic exposure to triclosan (TCS) (10-750 mg kg) in soil. TCS life cycle toxicity was evaluated by the means of survival, growth rate, and reproduction assessment. Biochemical responses including changes in the activity of antioxidative enzymes (catalase, superoxide dismutase, and glutathione reductase) and concentration of malondialdehyde (MDA) were determined.
