Ecosystem services and impact of industrial pollution on urban health: evidence from Durgapur, West Bengal, India

Moss as a passive biomonitoring tool for the atmospheric deposition and spatial distribution pattern of toxic metals in an industrial city

Anthropogenic pollution impacts human and environmental health, climate change, and air quality. Karabük, an industrial area from the Black Sea Region in northern Türkiye, is vulnerable to environmental pollution, particularly soil and air. In this research on methodological aspects, we analyzed the concentrations of six potential toxic metals in the atmospheric deposition of the city using the passive method of moss biomonitoring. The ground-growing terrestrial moss, Hypnum cupressiforme Hedw., was collected during the dry season of August 2023 at 20 urban points. The concentrations of Cr, Cu, Cd, Ni, Pb, and Co were determined in mosses by the ICP-MS method. Descriptive statistical analysis was employed to evaluate the status and variance in the spatial distribution of the studied metals, and multivariate analysis, Pearson correlation, and cluster analysis were used to investigate the associations of elements and discuss the most probable sources of these elements in the study area. Cd and Co showed positive and significant inter-element correlations (r > 0.938), representing an anthropogenic association mostly present in the air particles emitted from several metal plants. The results showed substantial impacts from local industry, manufactured activity, and soil dust emissions. Steel and iron smelter plants and cement factories are the biggest emitters of trace metals in the Karabük area and the primary sources of Cr, Cd, Ni, and Co deposition.

Advances in Ecosystem Services Valuation Studies in India: Learnings from a Systematic Review

Ecosystem services (ES) concept has gained global momentum as they hold immense importance for human well-being. On the other hand, direct and indirect drivers of biodiversity loss have led to deterioration of ecosystem health and their capacity to deliver ecosystem services. Worldwide, ES assessments have been increasingly used by administrators to formulate sustainable and environment centric policies. Similarly, there has been continuous expansion of ES related work in India to capture the material and non-material benefits derived from diverse ecosystems in the country. In the current paper, 105 research articles/reports have been reviewed to assess the growing trajectory of ES research and also to map their methodological approaches. The lacunae in the studies and literature have been critically examined. Analysis of the study shows that ES derived from forests have been captured widely while marine ecosystems have not received appropriate scholarly attention. Similarly, dearth of studies focusing on long- and short-term implications of climate change and other environmental challenges on the ES delivery was also evident. A strong need is felt to integrate interdisciplinary approaches for holistic ES assessment. Also, future ES assessments must assimilate traditional as well as indigenous knowledge systems within ES assessment framework to ensure formulation of tangible, sustainable policies.
