The COVID-19 pandemic has led to a significant increase in healthcare waste, including personal protective equipment (PPE), pharmaceutical residues, and viral pathogens, posing environmental and public health risks, especially in emerging economies like India. This study evaluates the environmental and health risks of healthcare wastewater during the pandemic, focusing on emerging pollutants like microplastics from PPE and pharmaceutical residues. A literature review analyzed the environmental impact, including the presence of SARS-CoV-2 RNA, antimicrobial residues, and microplastics, and explored wastewater-based epidemiology (WBE) for tracking viral spread and antimicrobial resistance (AMR).

Scene classification plays a vital role in various computer vision applications, but building deep learning models from scratch is a very time-intensive process. Transfer learning is an excellent classification method using the predefined model. In our proposed work, we introduce a novel method of multimodal feature extraction and a feature selection technique to improve the efficiency of transfer learning in scene classification.

The life of all creatures is supported directly or indirectly by soil, which is a significant environmental matrix. The soil has been polluted partly due to increased human activities and population growth, releasing several foreign substances and persistent contaminants. When toxic substances like polycyclic aromatic hydrocarbons (PAHs) are disposed of, the characteristics of the soil are changed, microbial biodiversity is impacted, and items are destroyed.

Serum samples from 840 animals were examined for Leptospira spp. antibodies by microscopic agglutination test (MAT) to assess the risk factors and the prevalence of leptospirosis among animal herds of Assam, Meghalaya, Mizoram the north eastern (NER) provinces. They were compared with Tamilnadu (TN) the southern province of India for the serovar and risk factor inconsistency.
