Ibuprofen Pollution in the Environment: A Critical Review of Sources, Physicochemical Properties, Ecotoxicological Implications, Human Health Risks, and Bioremediation Technologies

This review examines ibuprofen as an emerging environmental micropollutant, tracing its journey from pharmaceutical manufacturing and wastewater treatment into aquatic ecosystems. Researchers found that ibuprofen can harm aquatic organisms and persist in the environment depending on various chemical and biological factors. The study explores bioremediation technologies as promising approaches to remove this widespread pharmaceutical contaminant from water sources.

Bio-removal of bisphenol A by cyanobacterium Gloeocapsopsis crepidium

Researchers tested the ability of the cyanobacterium Gloeocapsopsis crepidium to biodegrade bisphenol A, a toxic endocrine-disrupting compound that can be released from microplastic pollution. The organism was exposed to varying concentrations of BPA under controlled laboratory conditions, and results showed significant bioremoval capacity. The study suggests that naturally occurring cyanobacteria may offer a low-cost biological method for reducing BPA contamination in aquatic environments.

Environmental Microplastics Exposure and Its Biochemical Impacts on Human Oxidative Stress Markers: A Clinical Chemistry Perspective

This clinical chemistry review examined how environmental microplastic exposure affects oxidative stress markers in humans, synthesizing evidence on circulating reactive oxygen species, antioxidant enzyme changes, and inflammatory biomarkers. The authors found consistent evidence that MNP exposure elevates markers of oxidative damage across multiple tissue types.

Employing Phytoremediation Methods to Extract Heavy Metals from Polluted Soils

This paper is not directly about microplastics in the typical environmental exposure sense; it studies phytoremediation — using the Dodonaea plant to absorb heavy metals (zinc, nickel, cadmium) from contaminated soil — with no connection to plastic or microplastic pollution.

Combined effect of nano boron,zinc, bio-inoculum and white fungus waste on P. aeruginosa numbers and amidase activity in soil.

Researchers investigated the combined effects of nano boron, nano zinc, bio-inoculum (P. aeruginosa bacteria), and white fungus waste on P. aeruginosa population numbers and amidase enzyme activity in agricultural soil at a field site in Iraq. The study evaluated how these soil amendments interact to influence beneficial bacterial activity and nitrogen-related enzyme function relevant to soil fertility.

Synthesis, characterization and swelling behavior of a novel bio-adsorbent based on pectin grafted poly (acrylic acid -co- itaconic acid) hydrogels for adsorption and controlled release of ciprofloxacin

Researchers synthesized a novel bio-adsorbent hydrogel by free radical copolymerization of acrylic acid and itaconic acid grafted onto natural pectin, characterizing the product by FTIR, SEM, XRD, and TGA, and optimizing swelling behavior and adsorption capacity for controlled release of the antibiotic ciprofloxacin.

Synthesis, Characterization of New Ligand Derived from 4-aminoantipyrine and its Complexes with Few Metallic Ions and Evaluation of their Activity as Anticancer

Researchers synthesized a new heterocyclic ligand derived from 4-aminoantipyrine and characterized its Ni(II), Cu(II), Zn(II), Cd(II), and Ag(I) metal complexes using NMR, FTIR, UV-vis spectroscopy, and X-ray diffraction, then evaluated the ligand and its complexes for anticancer activity.

Preparation complexes Co(III), Ni(II), and Cu(II) with novel azo-Schiff base ligand (N, N, O) derived from 2- amino- 6- methoxy benzothiazole with spectral characterization, study biological activity as anti-cancer, anti-oxidant to complexes

Researchers synthesised novel azo-Schiff base ligands derived from 2-amino-6-methoxy benzothiazole and prepared Co(III), Ni(II), and Cu(II) metal complexes, characterising their octahedral geometry by spectroscopic and thermogravimetric methods and evaluating their anti-cancer and anti-oxidant biological activities.

Growth rates, chlorophyll content and interaction comparison of microplastics effect on asterarcys sp. and cyanobacterium sp. in water body of euphrates branch (Shatt Al-Furat in Al-Dywaniah), Iraq

This study monitored microplastic levels in an Iraqi river branch from 2019 to 2020 and tested how different microplastic types affected algal and cyanobacterial growth. Microplastic concentrations increased over the monitoring period and negatively affected algal photosynthesis, raising concerns for aquatic food webs and water quality.

Monooxygenase and dioxygenases by bacterial specific enzymes network

This review examines bacterial monooxygenase and dioxygenase enzyme networks involved in the degradation of naphthalene and other polycyclic aromatic hydrocarbons (PAHs) found in coal tar, petroleum, and industrial sites. The study details how these enzymatic pathways metabolize PAHs and their relevance for bioremediation of contaminated environments.

Evaluation of Soil Pollution Levels in Al-Qadisiyah Governorate, Iraq Using Contamination Index and GIS

Researchers used geo-accumulation index analysis and GIS mapping to evaluate heavy metal contamination from cadmium, nickel, lead, and zinc in 28 soil profiles collected from Al-Shamiyah city in Al-Qadisiyah Governorate, Iraq. They found that cadmium showed the highest contamination levels, ranging from non-polluted to significantly heavily polluted, with nickel concentrations elevated near major drainage infrastructure.

Microplastic Contamination of Surface Sediment of Euphrates River, Iraq: A Preliminary Study

This preliminary study found microplastics in all surface sediment samples collected along the Euphrates River in Iraq, with fibers being the most abundant type. The findings represent the first documentation of microplastic contamination in this important river system.
