Toxic effects of tetracycline on non-target lichen .

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).

Comprehensive tetracycline, ciprofloxacin and sulfamethoxazole toxicity evaluation to earthworm Dendrobaena veneta through life-cycle, behavioral and biochemical parameters.

Veterinary antibiotics are widely spread in the environment, however, the knowledge about their impact on soil key species is still limited. 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.

Veterinary antibiotics differ in phytotoxicity on oilseed rape grown over a wide range of concentrations.

Residues of veterinary antibiotics are a worldwide problem of increasing concern due to their persistence and diverse negative effects on organisms, including crops, and limited understanding of their phytotoxicity. 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.

Self-reported behaviours and measures related to plastic waste reduction: European citizens' perspective.

Consumer attitudes and behaviour regarding consumption of plastic goods and proper waste management are of importance for reducing plastic and microplastic (MP) pollution. Therefore, based on Eurobarometer survey, this study aims to analyse European attitudes and behaviour related to plastic pollution reduction. Europeans acknowledge marine and river pollution as important environmental problems and are worried about plastics and MP environmental impacts.

Effects of elevated CO2 concentration and temperature on the mixed-culture grown wild mustard (Sinapis arvensis L.) response to auxin herbicide.

Recently, there has been growing concern over the potential impact of CO concentration and temperature on herbicide efficacy. 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.

Physiological and Biochemical Parameters of Common Duckweed after the Exposure to Tetracycline and the Recovery from This Stress.

In this study, the ability of L. to recover to normal growth, after being degraded in a tetracycline-containing medium, was extensively investigated. The plants were exposed to tetracycline (TC) at concentrations of 1, 2.

Biological assessment of contaminated shooting range soil using earthworm biomarkers.

Environmental contamination at shooting ranges is a widely known ecological problem. The aim of the study was to evaluate the extent of contamination and the ecotoxicity of a shooting range soil assessing the physiological and biochemical effects on earthworm Eisenia fetida (Savigny). Adult E.

Effects of nickel on morpho-physiological parameters and oxidative status in Brassica napus cultivars under different sulphur levels.

Increased levels of trace metals are an important problem of environmental pollution. Ni is one of the metals essential for normal plant development, but elevated levels usually cause deleterious effects on plant growth. The aim of the study was to evaluate the effects sulphur nutrition on growth, oxidative status, and Ni bioaccumulation of Ni-treated rape (Brassica napus L.

Assessment of air pollution at the indoor environment of a shooting range using lichens as biomonitors.

The aim of the study was to examine the changes in ecophysiological parameters and accumulation of heavy metals in lichens transplanted to a shooting-range environment. Thalli of the epiphytic lichen were transplanted from an unpolluted site to a shooting range. Chlorophyll a fluorescence, thiobarbituric acid reactive substances (TBARS), and damage to cell membranes in the lichen and thalli were determined after 3 months exposure period indoors in a shooting range.

Physiological response of the bioindicator Ramalina farinacea in relation to atmospheric deposition in an urban environment.

Urban air pollution is one of the most important environmental problems. Lichens are good bioindicators in air pollution studies because of their dependence on the atmospheric deposition for nutrition. The present study focused on the effects of urbanization on the composition of atmospheric deposition inputs and physiological parameters of transplanted epiphytic lichen Ramalina farinacea.

Assessment of Toxicity to Earthworm Eisenia fetida of Lead Contaminated Shooting Range Soils with Different Properties.

The objective of the study was to evaluate the toxicity of trace elements to earthworms (Eisenia fetida) in recreational and military shooting range soils. The earthworms were exposed to soils; then mortality, growth, and reproduction endpoints were determined. In the recreational shooting range, the total Pb concentration was 6151 mg kg and in the soil of the impact berm of the military shooting range, it was 653 mg kg.

O pollution in a future climate increases the competition between summer rape and wild mustard.

The initial aim of this study was to evaluate an effect of elevated CO concentration and air temperature (future climate) and O pollution on mono- and mixed-culture grown summer rape (Brassica napus L.) and wild mustard (Sinapis arvensis L.).

Waste of electrical and electronic equipment: Trends and awareness among youths in Lithuania.

Waste of electrical and electronic equipment (WEEE) has gained significant attention recently because of increasing consumption and related environmental impacts. This work focuses on Lithuania and analyses the trends of WEEE generation and management during the period 2008-2015. Attitudes and behaviour of students and pupils (main future consumers) regarding WEEE are also determined in this work.

Projecting the impact of climate change on phenology of winter wheat in northern Lithuania.

Climate warming and a shift in the timing of phenological phases, which lead to changes in the duration of the vegetation period may have an essential impact on the productivity of winter crops. The main purpose of this study is to examine climate change-related long-term (1961-2015) changes in the duration of both initial (pre-winter) and main (post-winter) winter wheat vegetation seasons and to present the projection of future phenological changes until the end of this century. Delay and shortening of pre-winter vegetation period, as well as the advancement and slight extension of the post-winter vegetation period, resulted in the reduction of whole winter wheat vegetation period by more than 1 week over the investigated 55 years.

Response of deciduous trees spring phenology to recent and projected climate change in Central Lithuania.

The analysis of long-term time series of spring phenology for different deciduous trees species has shown that leaf unfolding for all the investigated species is the most sensitive to temperatures in March and April and illustrates that forcing temperature is the main driver of the advancement of leaf unfolding. Available chilling amount has increased by 22.5 % over the last 90 years, indicating that in the investigated geographical region there is no threat of chilling shortage.
