“…Table 3 , Table 4 , Table 5 and Table 6 show the results of odorant and odour concentrations. The measurement results of methane are not presented, since every determination was below the quantification threshold, which may indicate that the source of gas emissions is not typical municipal waste; methane in biogas emitted from municipal landfills usually represents between 50% and 60% of the mixture [ 29 , 30 ].…”

During the pilot studies, it was found that the temperature of gases emerging from cracks in the ground was as much as 20 • C greater than the temperature of the ambient atmospheric air.…”

“…Municipal waste landfills, in contrast to hazardous waste landfills, are well recognized in the literature in terms of the processes occurring in the deposited waste and process gas emissions. The latter are mainly related to the decomposition of organic matter in the deposited waste [ 30 ]. Landfill gas consists mainly of methane (CH 4 , 50–60%), carbon dioxide (CO 2 , 40–50%), but also, as demonstrated by Young and Parker [ 31 ], hundreds of various chemical compounds present in trace amounts, the so-called trace gases (1%).…”

Mineral excavation is a common process throughout the world. The open pits remaining after the closure of a mine require well-considered and meticulous reclamation activities aimed at restoring the environmental properties of a given area. The inspections carried out in Poland indicate numerous irregularities in implementing the reclamation process. The research in this study was conducted in six measurement series and includes both chemical and olfactometry determinations by devices: multisensor portable gas detector and field olfactometer. Statistical analysis of the results obtained show high concentrations in ambient air of both chemical compounds (NH3, VOCs, H2S, CH3SH) and odour, excluding the possibility of occurrence in the pit of only waste types contained in the administrative decision on reclamation. In addition to the unpleasant odour, the listed compounds can have dangerous effects on the health and life of living organisms. This paper presents a suitable method of control and detection of irregularities in the conducted processes. The main advantage is the relatively low cost of purchasing sensors and field olfactometers compared to other devices, and the possibility to test the polluted air in situ, without the risk of chemical processes occurring during transport of gas samples to the laboratory.

“…Due to their long-term decomposition rates, landfills are a source of constant odour emissions (McKendry et al, 2002). Odours emanating from landfills is the result of the aerobic and anaerobic decomposition of waste materials into gaseous volatile compounds such as methane, oxygenated compounds and hydrocarbons, components known to be malodorous (Duan et al, 2021). Typically, landfills are located on the periphery of urban settlements, downwind from known sensitive land uses (Lane & McDonald, 1983).…”

Cannabis production standards are evolving with little understanding of their implications on land use planning. Health Canada currently administers a federally-regulated licensing system that does not address odour and light pollution land use impacts across the rural landscape. This literature review addresses the regulatory history of cannabis production in Canada, reviews current production standards, and compares possible cannabis production conflicts with documented land use conflicts from other odourous and light intensive operations to reveal flaws in the existing licensing system. Established cannabis production markets will be examined for further comparisons.

“…A crescente demanda pelo consumo de produtos industrializados leva à contínua produção de lixo. Com o crescimento econômico do país, esse problema foi agravado, pois sabe-se que o aumento do consumo e de produção impactam diretamente a produção de resíduos sólidos urbanos -RSU (Ferri et al, 2015;Duan, et al, 2021). A problemática dos resíduos sólidos urbanos é desde a etapa da geração até a disposição final.…”

O objetivo deste trabalho foi avaliar o processo de filtragem em escala piloto no pré-tratamento do lixiviado de aterro sanitário através de análises físico-químicas. Foram avaliados quatro tipos de filtros; nos quais os materiais filtrantes utilizados foram areia fina, média e grossa, carvão ativado, argila, brita n°0 e brita n°1. A análise estatística foi realizada por análise de variância (ANOVA) seguida pelo teste de Tukey, quando aplicável. Os dados foram expressos como média ± desvio padrão e os valores P<0,05 foram considerados estatisticamente significativos. O pH não obteve redução ou aumento significativo das análises dos filtros quando comparado com o lixiviado bruto, a condutividade elétrica obteve redução significativas no filtro 1 (p<0,001), 2 e 4 com p<0,05 quando comparado com o lixiviado bruto. No oxigênio dissolvido ocorreram aumentos significativos no filtro 1 e 2 (p<0,001) e no filtro 4 (p<0,01). Conforme a redução dos parâmetros, pode-se observar que o filtro 1 reduziu aproximadamente 50% da condutividade elétrica e obteve aumento de 377,75% no oxigênio dissolvido, sendo esses os maiores valores de redução e aumento dos parâmetros. A vazão dos filtros foram todas diferentes, na qual o filtro 4 obteve maior vazão e o filtro 3 com a menor vazão. Conforme a análise dos resultados, o filtro considerado o mais viável em relação a vazão e com a análise dos parâmetros foi o filtro 1.
