Unlocking Biochar’s Potential: Innovative Strategies for Sustainable Remediation of Heavy Metal Stress in Tobacco Plants

Scientifica, Journal Year: 2025, Volume and Issue: 2025(1)

Published: Jan. 1, 2025

Tobacco, being a globally cultivated crop, holds significant social and economic importance. Tobacco plants are susceptible to the adverse effects of heavy metals (HMs), particularly cadmium (Cd), which hinders root development, disrupts water balance, impedes nutrient absorption. Higher concentrations HMs, especially Cd, naturally accumulate in tobacco leaves due complex interactions within plant–soil continuum. The uptake Cd by from soil is influenced several factors, including type, pH, irrigation quality, chemical composition metal involved. Different techniques, such as bioremediation, phytoremediation, mycoremediation, have been employed tackle issue HMs. use biochar offers practical solution mitigate this problem. With its large surface area porous nature, can effectively alleviate HMs contamination. Under application, adsorption primarily occurs through physical adsorption, where ions trapped pores biochar. Additionally, electrostatic attraction, negatively charged surfaces attract positively ions, another major mechanism remediation facilitated In review, we documented, compiled, interpreted novel recent information on stress explored biochar’s role alleviating toxicity. By providing comprehensive review persistent threat posed crops exploring potential measure, work aims enhance our understanding contribute development sustainable agricultural practices.

Mitigation effect of alpha-tocopherol and thermo-priming in Brassica napus L. under induced mercuric chloride stress

BMC Plant Biology, Journal Year: 2024, Volume and Issue: 24(1)

Abstract Soil pollution with heavy metals has grown to be a big hassle, leading the loss in farming production particularly developing countries like Pakistan, where no proper channel is present for irrigation and extraction of these toxic metals. The study aims ameliorate damages caused by metal ions (Hg-Mercury) on rapeseed ( Brassica napus L.) via growth regulator (α-tocopherol 150 mg/L) thermopriming technique at 4 °C 50 maintain plant agronomical physiological characteristics. In pot experiments, we designed total 11 treatments viz.( T0 (control), T1 (Hg4ppm), T2 (Hg8ppm), T3 (Hg4ppm + °C), T4 tocopherol (150 m/L)), T5 T6 mg/L)), T7 (Hg8ppm T8 T9 T10 results revealed that chlorophyll content p < 0.05 antioxidant enzymes such as catalase, peroxidase, malondialdehyde enhanced up maximum level = Hg4ppm (50 under ppm mercuric chloride stress), suggesting high temperature initiate system reduce photosystem damage.

Investigating seasonal air quality variations consequent to the urban vegetation in the metropolis of Faisalabad, Pakistan

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Jan. 3, 2024

Abstract Urban atmospheric pollution is global problem and have become increasingly critical in big cities around the world. Issue of toxic emissions has gained significant attention scientific community as release pollutants into atmosphere rising continuously. Although, Pakistani government started Pakistan Clean Air Program to control ambient air quality however, desired levels are yet be reached. Since process mapping dispersion urban areas intricate due its dependence on multiple factors, such vegetation weather conditions. Therefore, present research focuses two essential items: (1) relationship between variables (temperature, relative humidity (RH), sound intensity (SI), CO, CO 2 , particulate matter (PM 0.5 PM 1.0 2.5 ) (2) effect seasonal change concentration magnitude variables. A geographic Information System (GIS) was utilized map residential Faisalabad, Pakistan. Pearson correlation principal component analyses were performed establish pollutants, vegetation, variation. The results showed a positive metrological most pollutants. Furthermore, with temperature cover. GIS distribution maps for 2.5, highest poorly moderated vegetated areas. it can concluded that requires rigorous design, planning, cost–benefit analysis maximize environmental effects.

Investigating the Influence of Seasonal Variability and Urban Green Spaces on Ambient Air Quality in an Urban Environment

Polish Journal of Environmental Studies, Journal Year: 2024, Volume and Issue: unknown

Global urbanization and increased emissions worsen air pollution, impacting both the environment health.Despite initiatives like Pakistan's Clean Air Program monitoring stations, inadequate management still fails to meet quality standards, posing risks environmental health of life.Thus, this study aimed find out fluctuations in due seasonal variations vegetation cover.The present was conducted spring autumn season Faisalabad city at selected locations.A geographic information system (GIS) utilized map parameters area.CO 2 , CO, temperature, relative humidity (RH), sound intensity, particulate matter were measured area.Air pollutants found be considerably higher than 24-hour standards NEQS compared season, which harms health.The CO humidity, PM 0.5 1.0 2.5 intensity values ranged from 320-370 340-390 ppm, 3.0-5.5,and 8.5-11 20-33 11-21 o C, 30-55 40-65%, 20-45 μg/m 3 75-100 80-105 110-135 120-145 40-65 35-60 dB, for seasons respectively.Furthermore, achieved maximum S 1 (poorly vegetated areas) rather 5 (densely areas).These significant changes highlight necessity frequent take proper actions reducing contaminants, particularly poorly vegetated, industrial, commercial areas.
