“…There may be a slight difference in some other studies across the world; because the waste characteristics, most times depend on the nature of the countries concerned [14][15][16]. African countries are generally hot, especially Nigeria, sitting close to the equator with temperatures varying between 24℃ -38℃ because it directly relates to the meteorological conditions on the site [1,17]. The low wind speed or low mixing height of the atmospheric weather conditions could severely affect the rapid expansion and release of odour into the environment.…”

“…It usually contains suspended and dissolved materials; and is considered one of the most common liquids that seep into our groundwater resources and contaminate them [3,14,15,16]. The increase in landfill gas emission rates across the world has generated a lot of complaints, especially in tropical countries [17][18][19]. The waste materials placed in an active dumpsite for many years will naturally decompose.…”

An electrical resistivity survey was carried out at a dumpsite and controlled station located about 200m away from the dumpsite to assess the vertical extent of leachate contamination of the dumpsite and its impact on the soil and groundwater resources. Subsurface resistivity of the dumpsite and the controlled stations were examined, which reflects the subsurface soil tolerance and the impact of the vertical extent of leachate contamination on the subsurface. The leachate infiltration may reflect the state and the quality of the groundwater. This implies that leachates from the dumpsite must have also migrated into the aquifer system, thereby contaminating the water-bearing unit.

Landfill odorous gas emission has been a serious environmental problem, especially for the residents or passersby on the road near the landfill. In this paper, in situ monitoring and the numerical CALPUFF model were adopted to analyze the odor nuisance problem caused by municipal solid waste (MSW) degradation in a large landfill. The static chamber technique was used to measure the odorous gas emission rate on the working area, temporary cover area, and final cover area of the landfill during Dec. 2016 and Apr. 2018. The results showed that the emission rate of H2S on the working area varied from 0.003 mg/m2/min to 0.98 mg/m2/min, and it was positively correlated with the ambient temperature. The emission of H2S varied between 0.125 kg/h and 1.09 kg/h on the working area, and it varied between 9.2 × 10−6 kg/h and 6.8 × 10−4 kg/h on the temporary cover when considering the impact of the holes in a high-density polyethylene (HDPE) membrane, and it was negligible on the final cover. The contribution rates of H2S emission in the whole landfill were 90.79%∼98.59% and 0.0008%∼0.52% for the working area and the temporary cover area, respectively. The numerical simulation showed that wind velocity and gas emission rates were the critical factors that affect odor dispersion. To limit the H2S-influenced area within the landfill site, proper engineering measures should be taken to ensure the H2S emission rate of lower than 15% of its original value.

“…Emission of odorous gases from mixed land use patterns along with landfill in the cities have resulted in nuisance and other problems associated with the setting up of waste treatment facilities in and around cities as studied and documented [2]; [13]; [15]; [19]; [21]; [22]; [26]; [27]; [32]; [34]; [35]; [37]. Odour can be expressed as the "perception of smell" or in scientific terms, "a sensation resulting from the reception of stimulus by the olfactory sensory system" [12].…”

Landfills contain vast quantities of waste as they are sites for deposition of a city's solid waste. This solid waste further undergoes the process of decomposition producing several byproducts such as odorous gases and volatile organic compounds. Both of these compounds have potential to severely damage physical and mental health of human. These components were analysed using AERMOD by United States Environmental Protection Agency (USEPA). AERMOD needs uniform and horizontally consistent surface and upper air parameters of meteorology. Along with AERMOD, Landfill Gas Emission Model (LandGEM Version 3.02) was used to form an emission inventory. LandGEM analyses odorous gases and VOCs. The dispersion of odorous gases over areas adjacent to landfill of Pune, India has been estimated from information on advances in emission inventory and field monitoring operation. Four odorous gases namely Total Landfill gas, Methane, Carbon Dioxide and Non Methane Organic Compounds (NMOC) were detected at 17 discrete places and were found within permissible limits.
