Abstract
The degradation of imidacloprid and acetamiprid in tea infusion by ultraviolet (UV) light irradiation was investigated in this study. Results showed that the influence of UV light irradiation on the quality of tea infusion was controllable and UV light irradiation was effective on the degradation of both pesticides. The maximum removal rates were 75.2% for imidacloprid and 17.6% for acetamiprid after irradiation (650 µW/cm,2 120 min). The degradation of both pesticides followed the first-order kinetics model. Three degradation products were identified for imidacloprid and one for acetamiprid based on liquid chromatography-tandem mass spectrometry analysis. The degradation pathway of imidacloprid involved in the cleavage of C-C bond with the loss of nitro group followed by the hydrogenation, oxidation and hydrolysis, while the degradation of acetamiprid involved in the oxidation at the chlorine atom with the bonding of C atoms at positions 1 and 4 on the pyridine ring. Simultaneously, the toxicity of both pesticides was mitigated by UV light irradiation according to LO2 cell toxicity evaluation. The study provided a low-cost and effective way to reduce imidacloprid and acetamiprid from tea infusion, and it has the potential to be applied to the ready-to drink tea beverage production in industrial scale.

Abstract
Due to its high solubility in water, a large amount of the neonicotinoid insecticide acetamiprid persisting in the soil of treated crops enters surface water or groundwater. The aim of this study was to investigate the photocatalytic degradation of acetamiprid in an aqueous medium. The experiments were carried out in an annular suspension reactor operating in recirculated batch mode and using a UV-A lamp as the radiation source. An appropriate modification of the commercial TiO2-P25 photocatalyst was carried out to reduce its band gap energy and electron-hole recombination as well as to extend the visible light range of TiO2. The photodegradation study was carried out using a three-factor two-stage Box-Behnken experimental design to investigate the main effects and interactions between the operating variables, such as solution pH, initial concentration of acetamiprid, and amount of photocatalyst. The efficiency of the processes was determined by high performance liquid chromatography. The first-order pseudo-reaction kinetic model, as a simplification of the models of Langmuir-Hinshelwood under conditions of relatively low acetamiprid concentration, was applied and the reaction rate constants were estimated. The results of the study showed that the initial concentration of the pollutant was the most influential factor for the photocatalytic degradation process. Using ANOVA analysis, a linear model was established to predict the system behaviour at different operating conditions. The highest conversion and rate constant of acetamiprid degradation were recorded in the experiment with the lowest tested concentration of acetamiprid (2 mg/L), the average concentration of photocatalyst (60 mg) and at pH 8.

Abstract
The aim of this work was to optimize the photocatalytic degradation of rhodamine B (RhB) using a four-factor Box-Behnken experimental design, and the study was carried out under artificial irradiation (24-W UV lamp) using ZnO in suspension. The Box-Behnken model has been validated with an error less than 5%. A total (100%) RhB removal and COD abatement rates were reached under optimal conditions of treatment time, ZnO dose, and stirring speed at different concentrations of dye. The study of the effect of irradiation type (solar and UV lamp) on the degradation of RhB showed that solar irradiation gave a better rate of degradation with complete discoloration after 2 hr. The study of RhB degradation mechanism indicates that O 2 ∙ - were the main active species for the degradation of this pollutant. The comparison between the degradation of RhB alone and RhB prepared with varnish (as it is usually used in industry) revealed that degradation of RhB alone is faster comparing than that of RhB/varnish mixture. The results showed that the biodegradability was improved after a contact time of 60 min with a BOD5 /COD ratio increasing from 0.23 to 0.90. PRACTITIONER POINTS: Optimization of the photocatalytic degradation of rhodamine B using a four-factor Box-Behnken experimental design. Investigation of dye mineralization. The degradation mechanism of rhodamine. Biodegradability assessment based on the BOD5 /COD ratio.

Abstract
Removal of persistent organic pollutants from water is quite challenging using biological treatment processes in waste water treatment plants. In order to improve the wastewater treatment quality for water reuse, many techniques are developed and the most commonly used is heterogeneous photocatalysis. This work studies the degradation of paracetamol (PAR), which is one of the most persistent pharmaceutical drugs in water, and widely used as an analgesic and antipyretic drug in Algeria. The paracetamol degradation has been carried out via heterogeneous photocatalysis, in a suspended solution of catalyst using a Compound Parabolic Collectors (CPC) reactor and in a fixed bed with immobilized catalyst under natural solar radiation. The degradation performance has been studied under various parameters such as substrate concentration and pH of solution. The degradation efficiency decreased when the initial paracetamol concentration increased from 2.5 mg/L to 20 mg/L. In addition, the selected reactors were found to be competent for the paracetamol degradation with an almost 98-99% removal of PAR. For the CPC reactor with suspended TiO2, the paracetamol elimination reached 98% after 300 min; however, for the fixed-bed reactor, TiO2 immobilized on cellulose-based paper was utilized, which yielded an almost 99% reduction in the PAR concentration after 90 min only of solar irradiation.

Abstract
Daphnids are freshwater crustaceans used in toxicity tests. Although lethality and immobilisation are the most commonly used endpoints in those tests, more sensitive parameters are required for determination of sublethal acute effects of toxicants. The use of various physiological endpoints in daphnids is considered as a low-cost and simple alternative that meets the 3R's rule (Replacement, Reduction, Refinement) criteria. However, currently there is no review-based evaluation of their applicability in toxicity testing. This paper presents the results on the most commonly determined physiological parameters of Daphnia in ecotoxicological studies and human drug testing, such as feeding activity, thoracic limb movement, heart rate, cardiac area, respiratory activity, compound eye, mandible movements and post-abdominal claw contractions. Furthermore, their applicability as promising endpoints in the assessment of water quality or drug testing is discussed.

Abstract
The effects of photo-degradation on the utilization of pesticides in agricultural production has been investigated. Various influencing factors were compared, with results showing that the initial pesticide concentration, light source, water quality and pH possessed different effects on neonicotinoids photo-degradation. The initial concentration and pH were found to be most critical effects. The photo-degradation rate decreased by a factor of 2-4 when the initial concentration increased from 5 mg L-1 to 20 mg L-1, particularly for acetamiprid and imidacloprid. The photo-degradation pathways and products of the five neonicotinoids were also investigated, with similar pathways found for each pesticide, except for acetamiprid. Degradation pathways mainly involved photo-oxidation processes, with products identified using liquid chromatography-quadrupole time-of-flight mass spectrometry (LC-Q-TOF-MS) found to be consistent with literature reported results. Bamboo vinegar exerted a photo-quenching effect on the neonicotinoids, with an improved efficiency at higher vinegar concentrations. The photo-quenching rates of thiamethoxam and dinotefuran were 381.58% and 310.62%, respectively, when a 30-fold dilution of vinegar was employed. The photo-degradation products in bamboo vinegar were identical to those observed in methanol, with acetic acid being the main factor influencing the observed quenching effects.
