Abstract Sediment contamination jeopardizes wetlands by harming aquatic organisms, disrupting food webs, and reducing biodiversity. Carcinogenic substances like heavy metals bioaccumulate in sediments expose consumers to a greater risk of cancer. This study reports Pb, Cr, Cu, Zn levels from eight India. The Pb (51.25 ± 4.46 µg/g) Cr (266 6.95 concentrations were highest Hirakud, Cu (34.27 2.2 Bhadrak, (55.45 2.93 Koraput. mean values exceeded the toxicity reference value. factor for was...
Abstract Scientific investigations on levels of Organochlorine Pesticide (OCP) residues in plants largely consider the edible parts (crops, vegetables, and fruit plants). Though non-edible are not eaten by human beings directly, these consumed livestock other animals, thereby facilitating flow chemical through food chain. The objective present investigation was to evaluate concentration OCP plant provide insights their potential ecotoxicological impacts. Eighteen were extracted nine...
Abstract Background Habitat heterogeneity clearly distinguished in terms of availability food and habitat resources landscape features (natural or human-modified) play a crucial role the avian species composition population structure. To examine this, study was carried out Bhubaneswar, India, to understand ecological niche distinction birds based on heterogeneity. Regular sampling conducted 30 sites covering six different types predominantly urban Bhubaneswar for understanding birds. The...
Particulate Matter (PM) pollution is a prime component of air and poses substantial risk to human health, including the eye. This work envisioned show impact PM2·5 on Ophthalmic disease prevalence in India. national-level observational-based cross-sectional retrospective study included hospital-reported ophthalmic outpatients 2019-20. The sector-wise high-resolution (0·1° × 0·1°) emission data along with annual average concentration for 2019 from NASA adopted factor analysis. Nearly 32·6...
We measured the background level and spatial variation of carbon (C), nitrogen (N), phosphorus (P), sulfur (S) associated basic soil parameters along depth profile for 3 years, in habitats (woodland, wetland, grassland), Keoladeo National Park (KNP), an important water fowl reserve a world heritage site India. The study examined soils at 5 depths (0, 0.25, 0.50, 0.75 1.0 m) i.e. from 2003 to 2005. Total organic C (TOC), total N (TN), available P (TAP), S (TAS), irrespective habitat type...
Abstract In view of the depleting oil reserves and exponential rise in petroleum prices, search for alternative sources fuel is very timely important. The present paper addresses underlying issues biodiesel production from biomaterials sustainable supply first-generation biofuels, especially one jatropha. agencies research institutions involved biofuels national international efforts made this regard are discussed here. There also a dire need step towards large-scale second-generation...
In a study on the butterfly community of Oussudu (Ousteri) Bird Sanctuary and its environs at Puducherry, total 63 species belonging to 47 genera under five families were recorded which included two endemics three Schedule I species. Nymphalidae was most diverse abundant family area followed by Pieridae. The paper also discusses abundance assemblage pattern in local fauna along with their legal/protection status distribution patterns area.
We examined the ammonium acetate extractable forms of alkali (Na, K) and alkaline earth (Ca, Li, Mg) metals in soil system a world heritage site, Keoladeo National Park, Bharatpur, India for 3 consecutive years—2003, 2004, 2005. The were assessed along profile, from surface to 1.00 m depth (as 5 layers, at 0, 0.25, 0.50, 0.75, m). Sodium K negatively correlated (P < 0.05) found range 40–4533 77–1802 mg/kg, respectively. distributions these significantly different among habitats (Na: F =...
Generation of baseline information about ambient air quality any given region assumes significance, when the area is 1) an active mine site, 2) proposed to be mined out in future, and 3) industrialization fast pace. Ambient monitoring (with respect SPM, RPM, SO2, NOx CO) was carried around two mining complexes western parts Kachchh district Gujarat generate status area. This has major various large scale industrial projects (thermal power plants, cement plants several ports jetties) are also...
A network of Protected Areas (PAs) has been the main strategy adopted in India for conservation biodiversity and wildlife. Thus, more than 600 PAs are established; however, pressures from human settlements proximity have a serious concern their management. To appreciate interplay governance around them, we selected Keoladeo National Park (KNP), Ramsar world heritage site India, as model. We compared socio-economic state inhabitants 13 villages dependency on KNP resources two decades ago with...
In view of the variety waste items casually disposed off by humans, a survey was conducted in two cities, Indore and Coimbatore, roosting sites colonial birds looking for unusual their food.Of 891 regurgitated pellets examined, about 53% Coimbatore 14% contained rubber bands, balloons small plastic debris.Rubber bands (95.3%), balloon (2.35%), bits (1.41%) cap (0.94%) were found pellets.Among red predominant colour (73.1%) followed green (25%) yellow (1.9%).These findings show that misjudge...
The chemical partitioning of Cu, Pb and Zn was examined in the soil profile woodland system Keoladeo National Park, India using a five-step sequential extraction procedure (SEP). Metal assessed up to depth 100cm with 25-cm intervals. amount metals obtained from SEP exceeded pseudototal metal levels aqua regia digestion. results showed high preferential attachment Fe—Mn hydroxides. All three least preferences exchangeable pool. OM-S phase also less, may be because low organic matter soil. In...
