“…Its concentrations varied between untraceable values and 293 µg m -3 , representing values up to 8.86 mg g -1 PM 2.5 . This anhydrosugar has long been pointed out as a tracer of the thermal breakdown of cellulose, which is a major component of biomass (Alves et al, 2019;Vicente et al, 2020). However, it has been speculated that the high temperature during cooking processes would also lead to the emission of levoglucosan due to thermal degradation of vegetable cellulose (He et al, 2004a) or decomposition of spices used as condiments (Hou et al, 2008).…”

“…Emission factors for trace gases and aerosols, as well as their chemical speciation for the open fire burning of pruning residues were investigated in Portugal. Burning prunings emitted substantial amounts of gaseous and particulate pollutants that can have harmful impacts on human health and ecosystems, including polyols which might occur as constituents in bacteria or fungi [25]. Elevated concentrations of arabitol and mannitol, fungal molecular tracers, were detected in fine particle samples collected in during a biomass burning season in China [26].…”

Biomass combustion is known to be one of the main contributors to air pollution. However, the influence of biomass burning on the distribution of viable bacterial and fungal aerosols is uncertain. This study aimed to examine survivability of bacteria and fungi in the post-combustion products, and to investigate the aerosolization of viable cells during combustion of different types of organic materials. Laboratory experiments included a small-scale combustion of organic materials contaminated with microorganisms in order to determine the survivability of microbes in the combustion products and the potential aerosolization of viable cells during combustion. Field experiments were completed during intentional and prescribed biomass burning events in order to investigate the aerosolization mechanisms that are not available at the laboratory scale. Laboratory experiments did not demonstrate aerosolization of microorganisms during biomass combustion. However, the relatively high survival rate of bacteria in the combustion products ought to be accounted for, as the surviving microorganisms can potentially be aerosolized by high velocity natural air flows. Field investigations demonstrated significant increase in the bioaerosol concentration above natural background during and after biomass combustion.

“…As in many emerging countries, the selected method in LC to manage solid waste is to pile up the waste in an open space and burn it down (Cheng et al 2020;Das et al 2018;Alves et al 2019). The LC has two main landfills, as shown in Fig.…”

Lae City (LC) of Morobe Province is the second-largest city in Papua New Guinea. Due to the abundant natural resources it inherits, the resultant urbanization has led to an influx of the human population. This increase in population as a result of industrialization has led to increased municipal solid waste (MSW) accumulation. To address this exigent issue, which affects the nation’s carbon footprint, it is imperative to review socio-economic and geographic factors to establish a feasible approach for managing MSW efficiently and sustainably. In the quest to achieve the same, the present assessment focuses on the 3 core waste management hierarchy systems to support sustainable development for LC by reviewing existing opportunities and challenges associated with the current MSW management system and the associated policies. The result shows that as a sustainable approach to MSW management of LC, a zero-waste campaign for resource recovery engaging all stakeholders can be implemented since the organic content of MSW generated in LC is as high as 70%. Moreover, the dumping of MSW at the dedicated dumpsite site can be minimized if policies are strengthened and the proposed waste avoidance pathway is implemented strictly. In addition to this, to avoid the contamination of groundwater and recovery of methane, the use of the Fukuoka approach in the existing landfills has been suggested to capture leachate without any huge expenditure.
