Face mask littering in coastal environment of Coromandel beaches, a comparison between street and beach littering - perspective and perceptions.

The usage of face mask has been encouraged globally to combat the COVID-19 pandemic. However, their improper disposal has begun to impact the environment. In the present study, face mask littering was assessed in sixteen stations across the beaches in Coromandel coast of South India for a period of four weeks.

Prevalence of microplastics in the sediments of Odisha beaches, southeastern coast of India.

The prevalence of microplastics along the coastal habitats has become a global concern owing to the increased input of plastic debris from multiple sources. The present study is the first of its kind to examine the prevalence and distribution of microplastics in Odisha coast. The average microplastic abundance in the nine stations along Odisha coastal beach is 258.

Prevalence and characteristics of microplastics present in the street dust collected from Chennai metropolitan city, India.

In the present study, we assessed the extent of microplastic pollution in the road dust of Chennai, the fifth largest metropolitan city in India. This study is the first of its kind to be reported from India. Sixteen different locations were selected from which road dust samples were collected.

Occurrence, distribution and composition of microplastics in the sediments of South Andaman beaches.

Herein, we report the prevalence of microplastics in the South Andaman beaches, India. The average microplastic abundance of the eight stations covered along the South Andaman beach was found to be 414.35 ± 87.

Quantification of microplastics using Nile Red in two bivalve species Perna viridis and Meretrix meretrix from three estuaries in Pondicherry, India and microplastic uptake by local communities through bivalve diet.

Microplastics ingested by two bivalve species Perna viridis and Meretrix meretrix collected from three estuaries viz. Ariyankuppam, Panithittu, and Chunnambar in Pondicherry, India was analysed for the first time in this research. Nile Red dye was used for microplastic detection.

Role of pretreatment and evidence for the enhanced biodegradation and mineralization of low-density polyethylene films by greater waxworm.

The present study reports the role of pretreatment for the enhanced biodegradation of low-density polyethylene (LDPE) with (Greater waxworm). The pretreatment of the LDPE film was carried out under solar radiation. The pretreated LDPE (PTLDPE) and untreated LDPE (UTLDPE) were characterized with AFM, FTIR and H NMR techniques.

Efficient biodegradation of polyethylene (HDPE) waste by the plastic-eating lesser waxworm (Achroia grisella).

Polyethylene (PE) is one of the major persistent plastic that is not biodegradable at considerable rates in most environments, and is the major source of unceasing environmental pollution. Recently, biodegradation of plastic wastes through waxworms and mealworms were reported. The present study focuses on the high-density polyethylene (HDPE) degradation capabilities of the larvae of Achroia grisella (lesser waxworm) and its ability to complete its life cycle when fed with HDPE.

Reclamation of grey water for non-potable purposes using pilot-scale solar photocatalytic tubular reactors.

Application of pilot-scale slurry-type tubular photocatalytic reactor was tested for the decentralized treatment of actual grey water. The reactors were fabricated by reusing the locally available materials at low cost, operated in batch recycle mode with 25 L of grey water. The influence of operational parameters such as catalysts' concentration, initial slurry pH and addition of HO on COD abatement were optimized.
