Abstract Microplastics (MPs) pollution is a serious environmental issue, particularly in heavily polluted cities of India. Despite its relevance, comprehensive studies on MPs contamination street dust are lacking. This primary study aims to address this gap by investigating across various areas Delhi during two different seasons. Samples were collected from four distinct locations Delhi: industrial (Okhla Phase 1), commercial (Connaught Place), institutional (CSIR-National Physical Laboratory), and landfill (Bhalswa) the post-monsoon summer abundance ranged 4.44 ± 1.11 100 g⁻¹ 18.88 4.00 areas. During summer, concentrations increased, with showing highest counts at 116.66 18.95 areas, lowest 35.55 12.52 dust. FTIR analysis identified polymers such as high-density polyethylene (HDPE), low-density (LDPE), polystyrene (PS), terephthalate (PET) whereas scanning electron microscopy (SEM) revealed degradation patterns surface MPs. Fragments fibres most common shapes reported both Our results confirmed widespread evidence Delhi, posing significant health risks. Immediate action collaboration needed develop effective mitigation strategies. provides foundation for future research interventions urban environments.
