AB  - Microplastics (MP) pollution has become a matter of global concern because of its 
      several deleterious effects on environmental health, especially on the 
      terrestrial environment. The evidence of MP contamination in terrestrial 
      environment is less explored compared to aquatic bodies. However, in Bangladesh 
      despite having high possibility of MP contamination, there is lacking of 
      available research-based evidence. Urban areas soil is subjected to act as a 
      major environmental reservoir for MPs. Thus, this study was carried out to 
      investigate the presence of MP contamination in constructed landfill sites near 
      Dhaka city, Bangladesh. Ten unmixed soil samples were collected from the 
      Aminbazar Sanitary landfill sites, from that thirty replicated samples were 
      investigated via Fourier Transform Infrared Spectroscopy (FT-IR) analysis and 
      Stereomicroscope. The range of physicochemical parameters were found in the soil 
      samples as follows: moisture content; 15.84%-56.54%; soil pH; 5.76-6.02, electric 
      conductivity; 0.1 mus/cm - 2.43 mus/cm, alkalinity; 6.7 +/- 1.528-14.33 +/- 0.577, TOC; 
      0.18% +/- 0.02-1.09 +/- 0.03. Among the ten samples, 3 samples were identified to 
      have the presence of MP in the form of Low density polyethylene (LDPE), High 
      density polyethylene (HDPE), and Cellulose acetate (CA) respectively. The 
      detection limit ranged from 1 - 2000 mum. Hence, the results show that the 
      procurement and discharge of MPs in the landfills is an overlong process. The 
      results of this study provide an initial evidence and affirm that landfill can be 
      a potential source of MPs. This study indicates that MPs are comparatively 
      overlong outcome of human induced activities which can significantly cause 
      changes in terrestrial ecosystems.
