The environment being surrounded by accumulated durable waste organic compounds has become a critical crisis for human societies. Generally, effluents of industrial plants released into the water source and air are removed some physical chemical processes. Utilizing photocatalysts as cost-effective, accessible, thermally/mechanically stable, nontoxic, reusable, powerful UV-absorber creates new gateway toward removal dissolved, suspended, gaseous pollutants even in trace amounts. TiO2 ZnO two prevalent field removing contaminants from wastewater air. Structural modification with metals, nonmetals, metal ions, other semiconductors reduces band gap energy agglomeration increases affinity composite structures to expand their usability on an scale. This extent light absorbance improves photocatalytic efficiency. Selecting suitable synthesis method is necessary prepare target photocatalyst distinct properties such high specific surface area, numerous functional groups, appropriate crystalline phase. In this Review, significant parameters TiO2- ZnO-based discussed detail. Several proposed mechanistic routes according provided. Some electrochemical analyses using charge carrier trapping agents delayed recombination help plot direction photoexcited species (electron–hole pairs) design more effective processes terms cost-effective photocatalysts, saving time increasing productivity.

Environmental risk assessment, spatial distribution, and abundance of heavy metals in surface sediments of Dal Lake-Kashmir, India

Environmental Advances, Journal Year: 2024, Volume and Issue: 17, P. 100562 - 100562

Published: June 26, 2024

This study assesses the pollution levels of Dal Lake in Kashmir, India, focusing on spatial distribution, abundance, and risk heavy metals surface sediments. Granulometric analysis revealed a complex interplay sedimentation processes, characterized by wide range sand (1.25% to 47.03%), silt (2.65% 58.21%), clay (38.35% 94.48%) contents across sediment samples. The average CaCO3 content 18.65% is notably higher than observed other regional global lakes, indicating production or preservation carbonates. organic matter (OM) within samples varied significantly, ranging from 3.9% 25.01%, reflecting sedimentary dynamics. Utilizing environmental assessment indices (Contamination Factor, degree contamination, Pollution Load Index, Potential ecological index, Enrichment Geo-accumulation Index) multivariate statistical analyses (Pearson's Correlation, Principal Component Analysis, Cluster Analysis), it examines contamination Iron, Manganese, Cobalt, Chromium, Copper, Nickel, Lead, Zinc 32 Results indicate variability metal concentrations, with Cobalt 24.1178 ppm 52.95 Iron 25,800.99 164,747.82 ppm, highlighting areas significant potential risks, especially which exceeds safe for benthic invertebrates. Index suggests moderate lake. These findings emphasize urgent need continuous monitoring effective management protect Lake's integrity.

EURASIAN JOURNAL OF SOIL SCIENCE (EJSS), Journal Year: 2025, Volume and Issue: 14(2), P. 158 - 177

Published: March 26, 2025

Biochar is a highly stable carbon compound produced through pyrolysis, and it has been widely studied for its potential to enhance soil fertility sequestration. However, the impact of fresh residual biochar not thoroughly explored. Therefore, comparative study on were conducted at filed conditions wheat cultivation, using randomized block design. A (S1), previous season crop (S2) two old (S3) with nine different treatments varied amounts rice husk straw along fertilizers (recommended doses N, P, K) considered in triplicate. Result clearly indicates that application significantly improved plant height, leaf area, dry biomass plant, internodal length, node & internode diameter, as well biological yield, grain yield crop. S1 had most significant growth yield-attributing characteristics compared S2 S3, even higher doses. In S1, results observed rate 5 tons/ha, while showed maximum 10 tons/ha. highest was recorded dose 15 The present findings conclusively efficiency agricultural production succeeding
