Microplastics are emerging contaminants in terrestrial ecosystems which could potentially affect crop growth at all stages. Amongst various stages, seed germination is one of the prime factors determines success a and remains unexplored. Hence, an experimental study was conducted to observe influence different concentrations (0.25, 0.50, 0.75 1.0%) polyethylene (PE) microplastics on blackgram (Vigna mungo L.) tomato (Solanum lycopersicum L.). Results indicated that after 24 hours exposure,...

Many sewage waste treatment systems are aiming for complete pathogen removal which necessitates search novel approaches that does not harm the environment. One such approach is exploring possibilities of bacteriophages removal. Hospital wastewater was collected from different locations Tamil Nadu and used study. The total heterotroph coliform population ranged 1.6 × 105 to 8.3 106 per mL 1.2 103 103/ 100 sample respectively. Higher frequency antibiotic resistant E. coli, Pseudomonas sp....

Although plastics provide numerous conveniences for human life, concerns about ecosystems and life are rising tremendously due to increased plastic production consumption. The ubiquitous presence undeniable distribution of microplastics (MPs) in agricultural usage created a major risk concern soil ecology health. ecological assessment sites the Coimbatore region South India has been evaluated using three indices: Pollution Hazard Index (PHI), Load (PLI), Potential Ecological Risk (PERI)....

This study examines the pollution of soil by chromium using statistical analysis and Empirical Bayesian Kriging (EBK) modeling around leather tanning industries Southern India. Sixty-four samples were collected from agricultural lands analyzed for their major ions trace elements Atomic Absorption Spectrophotometer. It is observed that concentration elements, decreases in following order: Cr > Fe Ni Pb Mn Cu Zn. Also, present ranged between 0.1 2459 mg/kg. The higher Cr, Pb, Ni, Zn this...

To explore the existence of microplastics (MPs) in agricultural soils Coimbatore region Tamil Nadu, India, this study was carried out six sites with distinct agronomic practices and inputs. Using density-digestion separation method, 81% organic matter (OM) removed MPs were quantified characterised using a stereo microscope ATR-FTIR. MP abundance treated sewage irrigated field (1,650 items kg−1) > paddy (1,500 integrated farming system (1,250 inorganic fertilisers applied (1,025 manures...

Reed plants are cost effective method of remediating the wastewater. To test removal efficiency pollutants from sewage and paper mill effluents, four different reed plant species, Canna indica (Indian Shot), Colocassia esculenta (Taro), Typha domingensis (Southern Cattail) Xanthosoma sagittifolium (Tannia), were compared for their effluents. Because high limited effects present physico-chemical treatments in wastewater treatment plant, this bed system can act as a cheaper process, that...

Seed dormancy is a significant challenge that hinders the successful germination of Sesuvium portulacastrum, halophytic species with promising applications in phytoremediation and coastal stabilization. This study aims to evaluate efficacy several dormancy-breaking treatments on S. portulacastrum seeds. The assessed include potassium nitrate, sulfuric acid, manual scratching, hot water treatment gibberellic acid (GA?) promoting Each was applied seeds rates were monitored determine...

The accelerating effects of climate change, driven by rising greenhouse gas emissions, necessitate identifying key contributors like aerosols, mainly black carbon (BC), due to their significant impact on global warming. This study investigates the temporal and seasonal dynamics BC aerosols in Ooty, Tamil Nadu, India, using a decade (2013–2023) data from an Aethalometer. Annual concentrations varied 0.51 µg/m³ (2020) 1.1 (2023), with decadal mean 0.75 ± 0.26 µg/m³. Distinct season al...

Bioaerosols, comprising viable and non-viable biological particles, significantly influence atmospheric processes, climate modulation human health. This study investigates the impact of climatic conditions on bioaerosol composition microbial dynamics at high altitudes Western Ghats, specifically ISRO ARFI Environmental Observatory in Ooty, Tamil Nadu, situated 2520 meters above sea level. Bioaerosol samples were collected using a high-volume respirable dust sampler with flow rate 1.4 m³/min...

Since the Industrial Revolution, global expansion has primarily depended on extraction of natural resources. Anthropogenic activities, such as widespread use fossil fuels, deforestation and other types land-use change, have increased levels greenhouse gases (GHGs) in atmosphere, contributing to climate change. The most essential task world is become carbon neutral by 2050 counteract deteriorating To achieve this goal, it required challenging modify present industrial processes minimise GHG...

The biotoxicity of chromium (Cr) present in the soil is determined by transformation and bioavailability chemical species. A better understanding these factors aids developing appropriate remediation strategies for Cr contaminated soils. work studied effect bioamendments conducting a laboratory closed incubation experiment 60 days (duration). physical properties were enhanced addition such as farmyard manure, composted poultry pressmud compost, biochar with two moisture conditions. reduced...

A study was carried out to evaluate the effect of elevated tropospheric ozone concentration on 15 rice cultivars. The cultivars were exposed a weighted average 51 ppb ±10% (10:00–17:00 h) for 30 days its reproductive stage. On an average, significantly affects photosynthetic rate (−19.23%), stomatal conductance (−21.35%) and contents chlorophyll (−27.19%), malondialdehyde (+121.43%), proline (+98.38%), ascorbic acid (−20.99%) over control. Linear multiregression 3D model fits leaf traits...
