Biomonitoring is a well-established method for assessing people's exposure to contaminants in the environment. Many non-communicable diseases can be prevented or aggravated by physiologically monitoring heavy metals biological matrices such as urine, evaluating their association with diseases, and attempting limit them. The focus of this research was determine between potentially toxic elements (PTE) arsenic (As), lead (Pb), chromium (Cr), zinc (Zn) urine concentrations anthropometric...

Abstract A novel magnetic biocomposite adsorbent, denoted as AgZnFe 2 O 4 @Ch, was utilized for the degradation of Metronidazole (MNZ) from water. Various analytical techniques, including vibrating sample magnetometer (VSM), X-ray diffraction (XRD), Brunauer–Emmett–Teller, Fourier transform infrared spectroscopy, and field emission scanning electron microscopy (FESEM), were applied to investigate characteristics adsorbent. XRD examination confirmed formation spinel ferrites phases. FESEM...

Reactive-oxygen-species are produced more often in the body when bisphenol A (BPA), an endocrine-disrupting-substance, is present. In this investigation, bio-sorbents from aqueous solution adapted Aloe-vera were used to survey BPA removal. leaf wastes create activated carbon, which was then analyzed using Fourier transform infrared (FTIR), Field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Thermogravimetric analysis (TGA), Zeta potential, and Brunauer-Emmett-Teller...

Human activities and climate may have an impact on the water quality of reservoirs. Therefore, present research aims to use entropy index assessment technique analyze features main supply reservoirs as well investigate effect parameters In this study, total non-carcinogenic health risks from various exposure paths were estimated for adults children. The major in Kohgiluyeh Boyer-Ahmad province was typically poor unfit human consumption. Besides, risk higher males (0.958–1.497) children...

Endocrine-disrupting chemicals (EDCs) can be a major risk factor for noncommunicable illnesses, especially when children are exposed to them. The purpose of this study was assess the urine concentrations triclosan (TCS), methyl (MTCS), triclocarban (TCC), and 2,4-dichlorophenol (2,4-DCP) its association with anthropometric demographic parameters in adolescents aged 6-18 living Kerman, Iran, 2020. A GC/MS instrument used measure analytes. TCS, MTCS, TCC, 2,4-DCP geometric mean (µg/L) were...

Nowadays, the presence of humic acid (HA) in water sources is highly regarded due to production extremely harmful byproducts such as trihalomethanes. In this study, effectiveness an Ag3PO4/TiO2 catalyst produced by situ precipitation a heterogeneous for degradation existence visible and solar light was evaluated. The catalyst's structure characterized using X-ray powder diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), after which dosage, HA...

Abstract This study aimed to evaluate the concentrations of sulfur dioxide (SO2) and nitrogen oxides (NOX) around Qom (a province in Iran) combined cycle power plant relation seasonal variations fuel type from December 2014 May 2015. Passive sampling was used three monitoring sites assess noncarcinogenic health risks associated with exposure SO2 NOX. Results showed higher NOX winter than spring. The highest (when plants gasoil) spring gas fuel) were 52.70 ± 21.70/52.70 13.20 22.10 7.00...

Abstract Pharmaceutical pollutants represent a significant class of industrial contaminants known for their persistence and adverse effects on the environment, posing substantial concern global ecosystems. Addressing removal these has become imperative in contemporary environmental management strategies. Among various remediation techniques, adsorption process stands out as an effective method treating diverse wastewater streams. In this context, utilization adsorbents plays pivotal role...
