Domestic waste disposal practices and awareness about its impacts on environment and human health in an islandic village: Akhada-St. Estevam in Goa
(ACS Publisher, 2025) Halankar, Richa; Naik, Neethu; Rath, Prabir Kumar
Effective domestic or household waste management is crucial for environmental sustainability and public health. Improper disposal practices lead to adverse sanitation, pollution, disease outbreaks and ecosystem degradation. This study examines waste disposal practices and awareness level among the households in a selected village in Tiswadi taluka of Goa. While residents show high awareness of the harmful effects of improper waste management, a significant gap exists between knowledge and action. Factors such as poor recycling habits, lack of infrastructure for waste disposal and limited public education contribute to this issue. By analysing household behaviours and perceptions, the study aims to recommend strategies for improving waste management practices and enhancing community health and sustainability. Improper waste disposal continues to pose significant environmental and public health challenges contributing to pollution, fear of disease outbreaks and the degradation of ecosystems. This study evaluates household waste management practices, awareness levels, and perceptions among 60 respondents from a selected village. Data collection was facilitated through structured questionnaires and findings were analysed using tables and visualized through pie charts created in Microsoft Excel to better understand patterns and trends.
A majority of respondents reported suffering from allergies due to waste exposure, and many experienced infectious diseases, highlighting immediate health threats stemming from poor waste management. The study also found that while several respondents consistently separated waste, a considerable number displayed inconsistent segregation practices. Daily waste disposal was commonly observed among households, reflecting regular management efforts; however, recycling habits remained poor, with most respondents rarely recycling and none reporting frequent recycling. Many individuals reused plastic bags, which is a positive trend, yet harmful practices like burning plastic and dumping in water bodies still persist among a minority.
The findings suggest that there is lack of confidence in local government initiatives and poor recycling support. The study recommends strengthening institutional waste management support, expanding public education initiatives focused on sanitary and household waste disposal, improving waste segregation facilities and promoting community engagement to bridge the gap between knowledge and practice. Addressing these issues is crucial to ensuring sustainable development in the studied communities.

New Mn(II) Mefenamates Appended by Substituted Bipyridine Linkers: Structural, Thermal, Magnetic, and Biological Investigations
(John Wiley & Sons, 2025) Vernekar, Beena K.; D'souza, Luann Romayne; Narvekar, Kedar Umakant; Gaonkar, Sanket Krishnanath; Bhowmik, Pradip Kumar
Two new manganese complexes of NSAID mefenamic acid (Hmef) with heterocyclic diimines, 4,4′-diethoxy 2,2′-bipyridine (DEB) and 4,4′-dimethyl 2,2′-bipyridine (DMB) were synthesized. DEB crystallised in triclinic Pī space group, exhibiting a 2-D network. MM1 crystallised in triclinic P1 space group, with mef2- adopting monodentate and bidentate chelate modes to Mn, owing to its flexibility and DEB with bidentate chelation. The interplay of O─H···O, N─H···O, and C─H···O interactions stabilised the overall lattice of MM1. MM2 crystallized in triclinic Pī space group with mef2- and DMB adopting diverse coordination modes to Mn and the π–π stacking and hydrogen bonding interactions gave rise to a parallel alignment of Mn units when extended along b axis. The thermalprofiles of MM1 and MM2 corroborated with the crystal structure, evidencing the loss of solvent between RT- 127 °C, followed by ligand decomposition. XPS analysis of MM1 and MM2 validated the presence of Mn in + 2 oxidationstate, thereby confirming ligand composition. The magnetic susceptibility values for MM1 and MM2 increased with decreasing temperature, suggesting paramagnetic nature of Mn(II) in both the compounds. Interestingly, MM1 and MM2 exhibited 15.67 ± 0.21 % and 19.17 ± 0.10 % cell viability, respectively, of HepG2 cancerous cells at 100 µg/mL and possessed DNA cleavage activity, indicating their role in biomedical applications.
