The presence of antibiotics residues in aqueous effluents is a potential concern due to their potential adverse effects on living organisms. In this work, perylene tetracarboxylic acid-functionalized expanded graphite (PTCA-EG) was synthesized as a metal-free adsorbent and its potential for efficient treatment of contaminated wastewater with cefalexin (CLX) antibiotic was studied. The experimental variables were modeled and optimized using central composite design (CCD) and response surface methodology (RSM) to maximize adsorption efficiency. In this regard, the contact time of 20 min, solution pH of 7.0, adsorbent dosage of 18 mg, and initial CLX concentration of 45 mg L<sup>−1</sup> were found to be the optimum conditions for adsorptive removal of CLX with a maximum efficiency of 99 ± 1.21%. In addition, the adsorption equilibrium data were well analyzed with isotherm, kinetic, and thermodynamic studies. The isotherm results revealed the adsorption process was favorable and took place on the heterogeneous surface. Moreover, the Langmuir maximum adsorption capacity (<i>Q</i><sub>max</sub>) was determined as 220.7 mg g<sup>−1</sup>.

In this study, the effect of organophosphate insecticides, dimethoate (DM) and malathion (MT), was investigated on <i>Solanum lycopersicum</i> L. The seeds were germinated under in vivo conditions and after 1 month of germination, they were transferred to separate pots. Insecticides were applied in three different concentrations (X, 2X, and 4X) using a nozzle spray at 7-day intervals for 21 days where X was the recommended dose. After 21 days of treatment, the toxicological responses of plants were confirmed by evaluating the growth patterns, anatomical, photosynthetic pigments, expression of proteins, and antioxidant enzymes catalase (CAT), guaiacol peroxidase (GPX), and ascorbate peroxidase (APX). The study findings demonstrated that both DM and MT treatment resulted in adverse growth effects even at the initial recommended dose (X) of application. However, compared to MT, at 4X concentrations of DM, maximum decrease in plant height (43.43%), leaf length (43.16%), leaf width (41.09%), and total numbers of leaves per plant (50.57%) was observed. Plants subjected to higher doses of DM and MT showed a gradual reduction in chlorophyll<i> a</i>, chlorophyll <i>b</i>, total chlorophyll, and carotenoids (67.25, 50.00, 62.03, and 41.04%, respectively, for DM and 61.75, 55.72, 59.87, and 41.04%, respectively, for MT). In addition, higher doses of these insecticides greatly disturbed micromorphology and protein contents. At high dose (4X) of treatment, the activities of CAT, GPX, and APX were found to increase by 14.01, 3.62, and 2.21 times the control value, respectively, for DM and 5.17, 2.53, and 1.46 times, respectively, for MT. Additionally, increased isoenzymes of CAT, GPX, and APX were demonstrated by nondenaturing PAGE and were also dependent on the concentrations of DM and MT. These results suggest that the isoforms of the antioxidant enzymes newly developed due to DM and MT excess may be used as biochemical markers for other crop plants grown under insecticide stress.

Despite the critical role of pesticides in safeguarding crop yields, the lack of regulatory enforcement and monitoring in Nigeria poses significant challenges. The review underscores the importance of understanding the health implications of pesticide residues in food. While acute and sub-chronic health effects of OPP exposure have been studied, there remains a need for a focused review of the long-term impacts, particularly in the context of limited regulatory oversight. Additionally, the manuscript highlights gaps in knowledge regarding the effects of pesticides on biodiversity, ecosystems, and vulnerable populations such as children, pregnant women, and the elderly. Recommendations include longitudinal studies to assess cumulative and delayed health consequences, systematic reporting of poisoning incidents, and routine analysis of food products to ensure safety.

OH rate coefficients were determined in UCLM, between 263 and 353 K and 50–600 Torr, using the absolute rate method of pulsed laser photolysis-laser-induced fluorescence technique, while Cl kinetics were studied in temperature (260–363 K) and pressure (34–721 Torr) ranges, using the relative rate method of the thermostated photochemical reactor equipped with Fourier transform infrared spectroscopy as the detection technique. In both OH and Cl reactions, a negative temperature dependence of the measured rate coefficients was observed, which is consistent with complex association reactions. The temperature dependence of OH rate coefficients was found to be well represented by the following expression: <i>k</i><sub>1</sub>(T) = (2.30 ± 0.35) × 10<sup>−12</sup> exp[(544 ± 46) K/T] cm<sup>3</sup> molecule<sup>−1</sup> s<sup>−1</sup>.

Additionally, statistical methods are used to assess the potential MSW management approaches. A comprehensive methodology has been adopted, including house-to-house waste collection from 25 pre-selected locations, to ensure representation across different income groups. The collected waste was segregated into food, plastic, paper, and textile waste categories, and the moisture content was analyzed using the oven-drying method. Further, it has been observed from the obtained result that 0.44 kg per/capita/day of MSW has been generated from the study area. The result shows that vegetable waste contributes the most followed by food waste and plastic. Additionally, the moisture content of the waste ranged between 12% and 76.25%, with high moisture content primarily found in organic wastes. Moreover, interpolation maps created using QGIS highlighted the spatial distribution of waste generation across the town.

The Moments-Quantile Regression method is employed to assess the effectiveness of these policies across countries with varying levels of emissions—high, medium, and low within the Environmental Kuznets Curve. The findings indicate that increased stringency in environmental regulations correlates with reduced carbon emissions per capita. Notably, the EPS index has a more significant effect on reducing PBA emissions compared to CBA emissions. A key finding is that the EPS index is more effective in countries with lower pollution per capita (i.e., lower quantiles) than in those with higher pollution per capita. Among the three components, market-based instruments are identified as the most effective in reducing carbon emissions. Additionally, in countries where per capita emissions are relatively low, the combination of market and non-market instruments proves to be the most effective in reducing emissions.
