Abstract There is a growing threat of wastewater pollution impacting human access to clean water. The surge in pharmaceuticals and personal care products (PPCPs) such water has reached alarming levels, posing an unprecedented aquatic ecosystems health. Conventional treatment not specifically tailored address the presence PPCPs. This paper examines possibility using nano-chitin chitosan as effective sustainable adsorbents for removal PPCPs from wastewater. recent progress functionalized or composites reviewed with attention enhanced adsorption capacity selectivity toward different classes Unique features chitosan, their large surface areas biocompatibility making them good choice PPCP adsorption, are also discussed. Critical evaluation given about how these nanomaterials absorb by looking at various mechanisms like electrostatic interactions, hydrogen bonding, hydrophobic interaction, among others. Finally, future research directions provided improving performance scalability bio-based Graphical

Biostimulant application can be considered an effective, practical, and sustainable nutritional crop supplementation may lessen the environmental problems related to excessive fertilization. Biostimulants provide beneficial properties plants by increasing plant metabolism, which promotes yield improves quality of crops; protecting against stresses such as water shortage, soil salinization, exposure sub-optimal growth temperatures; promoting via higher nutrient uptake. Other important benefits include enzymatic microbial activities, changing architecture roots, solubility mobility micronutrients, enhancing fertility soil, predominantly nurturing development complementary microbes. are classified microbial, arbuscular mycorrhizae fungi (AMF), plant-growth-promoting rhizobacteria (PGPR), non-pathogenic fungi, protozoa, nematodes, or non-microbial, seaweed extract, phosphite, humic acid, other inorganic salts, chitin chitosan derivatives, protein hydrolysates free amino acids, complex organic materials.

In recent decades, previously unobserved trace compounds have become more widely detected in wastewater treatment effluents and freshwater ecosystems. Emanating from various sources presenting potential human health ecological risks at much lesser concentrations than traditional contaminants, detection of “emerging contaminants” has increased with improvements analytical techniques. The behavior emerging contaminants wetlands is a topic increasing interest, as natural are known to transform sequester pollutants constructed or utilized address elevated constituents concern. Both complex biogeochemical systems interrelated abiotic biotic mechanisms leading the removal contaminants.

Harmful cyanobacterial blooms have increased globally, releasing hazardous cyanotoxins that threaten the safety of water resources. Constructed wetlands (CWs) are a nature-based and low-cost solution to purify remove from water. However, bio-mechanistic understanding biotransformation processes expected drive cyanotoxin removal in such systems is poor, primarily focused on bacteria. Thus, present study aimed at exploring fungal contribution microcystin-LR cylindrospermopsin biodegradation CWs. Based CW mesocosms, two experimental approaches were taken: a) amplicon sequencing studies conducted investigate involvement community; b) isolates tested for their degradation capabilities. The data uncovered effects seasonality (spring or summer), exposure, vegetation (unplanted, Juncus effusus Phragmites australis) substratum (sand gravel) community structure. Additionally, arbuscular mycorrhizal fungus Rhizophagus endophyte Myrmecridium showed positive correlations with removal. Fungal revealed microcystin-LR-removal potentials approximately 25 % vitro experiments, while extracellular chemical fingerprint cultures suggested potential intracellular metabolization. results this may help us understand removal, as well ecology
