Abstract The occurrence of pharmaceutical compounds in surface water is global concern. Therefore, this study was conducted to assess the acetaminophen, caffeine, ibuprofen, diclofenac, aspirin, diazepam, and tramadol samples from hospitals, waste stabilisation ponds, river Obuasi metropolis, Ghana. Solid phase extraction (SPE) sample preparation followed by analysis using high-performance liquid chromatography (HPLC) method performed on samples. removal efficiency these pharmaceuticals ponds area also determined. Finally, ecological risk posed analysed estimated as quotient (RQ). All seven were found all hospital effluent, water, indicating their aquatic systems municipality. Acetaminophen most prevalent compound study, with a maximum concentration 23.0 µg/L, while diazepam least pervasive compound, 2.0 µg/L. percentage pond ranged 61.5 82.2%. RQs 0.0 0.191 for 0.0002 0.209 stabilization 0.0–0.295 wastewater. This indicates that RQ could pose low medium risk. has revealed possible threat pharmaceuticals; thereby staking justifiable claim an urgent action against water. ,

Microplastic pollution (MPs) emerged as a significant environmental concern due to its persistent nature. These MPs particles endure in waters, soils, and even the atmosphere, posing potential threats entire ecosystem. Aquatic organisms are at risk of ingesting MPs, leading accumulation tissues, ultimately affecting food chain. This study aims provide an overview sources distribution, impacts. have been documented various substances such bottled water, salts, seafood, air. However, full extent health consequences on human exposure remains uncertain. Therefore, it is imperative that we draw public attention presence these pollutants environment. To mitigate adverse effects reducing plastic consumption, implementing improved waste management practices, advocating sustainable behaviors essential for well-being natural ecosystems populations.

Antiviral drugs such as lamivudine have been globally identified in the environment and marked emerging pollutants of concern due to their bioactive extremity. Following therapeutic uses, approximately 70% oral dose is eliminated renally parent drug. Concerns has raised for neighbouring aquatic bodies effluent produced from production plants containing high concentrations antiviral drugs. drugs, lamivudine, are extremely bioactive, prompting interest urgent removal environment. The purpose present study was optimize synthetic solution using jamun seed (JS) (Syzygium cumini) biochar. influence sorption parameters pH, concentration, adsorbent dosage, contact time, calcination temperatures on investigated optimized a response surface methodology (SRM) based optimal design. results indicated that, quadratic model best fits data with regression coefficient R2, adjusted predicted R2 0.9934, 0.9761 0.8340, respectively. JS biochar calcined at 750 °C, pH 8, initial concentration 10 ppm time 30 min maximum experimental efficiency 84.9%. residual standard error (RSE) value 3.5% implying that reliable. Isotherm adsorption followed Freundlich isotherm, an 0.9977 while modified Langmuir 0.9852. These findings potentially useful other organics contaminated water wastewater effluents. Therefore, this presents environmentally friendly remedy against healthier ecology.

Scientific interest in antimicrobial pollutants, such as ciprofloxacin, has increased. Due to spread of antibiotic-resistant bacteria, resistance genes, and their dissemination the environment. Therefore, remediation is necessary ensure ecological sustainability. The current study aimed optimise removal ciprofloxacin from synthetic water using jamun seed (JS) (Syzygium cumini) biochar a response surface methodology (RSM). Result indicates elimination efficiency ranged between 32.46 94.95%, indicating material can be improved used for organics. residual standard error 4.4% were found predicted model, implying that model credible predict future experimental findings. R-squarred value Langmuir model's R2 0.9681 which inclose agreement with Freundlich isotherm, 0.9757. JS could utilized contaminated wastewater safety

This study aimed to identify and quantify the total dust exposure underground miners in Mererani, Tanzania, its composition generate evidence for informed decision- policy-making. The Analytical Air Monitoring System (AMS) was used collection, analysis conducted gravimetrically. analysed using Inductively Coupled Plasma Optical Emission Spectroscopy. results showed significant variation levels across different mining zones, with inhaling up 1859 mg of over an 8-hour period drilling zones (DZ), 797 loading (LZ), 382 resting (RZ). mean value significantly different, a p-value <0.05. Miners had higher heavy metal silica than those from unmined sites, chromium being most dominant element all samples. Cumulative time is linked long-term respiratory impairment serious health conditions such as lung cancer. These findings highlight need intervention, including education on hazards, provision personal protective equipment (PPE), enforcement safety standards safeguard miners' health. Addressing these issues critical promoting policy reforms sustainable practices Mererani similar communities.
