Soil degradation due to industrialization is a growing global concern, emphasizing the importance of evaluating soil quality near industrial zones to ensure food security, environmental sustainability, and public health. This study compares soil quality across five industrial sites, including foundries, electroplating, paper mills, textile mills, and quarries and cement industries, in the Coimbatore district. Soil samples were collected via a purposive sampling approach from nearby agricultural fields via a 500 m grid.

Background: Soil-transmitted helminths (STH) affect approximately 1.5 billion people globally. The current STH control strategy is annual or twice-annual preventive chemotherapy, typically school-based deworming targeting children and women of reproductive age.

- - The study assessed the prevalence of childhood disability in Tamil Nadu, India, focusing on how functional difficulties affect school enrollment among 29,044 children aged 5 to 17 years.
- - Out of the children surveyed, 1.0% were found to have functional difficulties, with common issues being related to understanding and walking, and this disability significantly impacted their likelihood of enrolling in school (Prevalence ratio 4.59).
- - The findings reveal substantial differences across age and socioeconomic groups concerning the effect of functional difficulty on school enrollment, emphasizing a critical need for targeted interventions to improve educational access for affected children.
Article Synopsis
- * Researchers developed a sensitive method to detect STH DNA in soil samples (20 g) from households in Kenya, Benin, and India, using advanced techniques like qPCR and ddPCR to identify specific STH species.
- * The study found a significant association between STH detection in soil and human infections, highlighting that soil tests could be more reliable than microscopy, which often underestimated or overestimated STH prevalence.
This study aimed to investigate how the decomposing scale effect, technique effect and composition effect of foreign direct investment (FDI) impact on carbon dioxide (CO) emissions for 115 nations spanning 1999 to 2019 by employing Generalised Method of Moments (GMM) model. The results indicated that FDI, real GDP per capita, capital-labor ratio, institutional quality and urbanization increase CO emissions while the square of real GDP per capita and trade openness contributed to reducing CO emissions. Also, our findings fail to support Environmental Kuznets Curve (EKC) theory.
