“…Recently recent researches put in question the current quality of the indoor-versus the outdoorenvironment in contrary to the common belief that the built environment is well protected (Mendoza et al, 2021). In Anogeia, more than half of occupants had the perception that there was no deterioration in the indoor air quality as a result of wood burning; notwithstanding, it should be noted that one out of two left a window open.…”

In several European rural communities, woody biomass is considered amongst the most important energy sources for heating and cooking. However, the use of old-fashioned replaces may affect indoor and outdoor air quality. To depict this situation and to plan the necessary improvement interventions, a pilot action was implemented in a typical mountainous Mediterranean area (town of Anogeia, Crete). The action involved: (i) identi cation of the quantities, use and source of the woody biomass used in the community based on the analysis of data collected through a systematic survey; (ii) on-site indoor and outdoor measurements of air quality (CO 2 , CO, NO X , PM), during wintertime and summertime. Based on the current survey, around 70% of the study area households in Anogeia using woody biomass for heating purposes in low energy e ciency systems resulted in high annual consumption of rewood.Fifty-three per cent of occupants didn't consider indoor air quality as a result of wood burning. The analysis of the air quality showed very high concentrations of indoor air pollutants in the majority of old buildings with seniors using traditional heating systems. The type of main/supplementary heating system used in a dwelling depends on factors such as the size of the dwelling, year of construction, education level and age of occupants. The results also demonstrate a strong correlation/liaison between the heating season (summertime/wintertime), and the (signi cant increase in the) concentrations of air pollutants in the sampling sites.

“…As a result, schools were shown to be more protective against the secondary pollutants that dominate inversion episodes -following a short lag, than during other situations. What remains concerning is that outdoor air during other pollution events has not been found to behave this way 22 . Since we found notable differences between outdoor air quality at the two schools, this may be a source of concern for other elevated pollution events such as wildfires.…”

“…Since indoor air quality is affected by outdoor 22 and indoor sources of pollution, environmental conditions, housing characteristics, and behavioral factors 23 , we installed research grade sensors to observe PM2.5 concentrations in indoor and outdoor settings at two high schools with a range of geographic and demographic compositions, (e.g., elevation, distance to pollution source, minority status, income level, etc.). These data and resulting analysis show that poor air quality may impact school settings, and the potential implications with respect to environmental inequality.…”

Every day around 93% of children under the age of 15 (1.8 billion children) breathe outdoor air that is so polluted it puts their health and development at serious risk. Due to the pandemic, however, ventilation of buildings using outdoor air has become an important safety technique to prevent the spread of COVID-19. With the mounting ev-idence suggesting that air pollution is impactful to human health and educational out-comes, this contradictory guidance may be problematic in schools with higher air pol-lution levels, but keeping kids COVID-19 free and in school to receive their education is now more pressing than ever. To understand if all schools in an urban area are ex-posed to similar outdoor air quality and if school infrastructure protects children equally indoors, we installed research grade sensors to observe PM2.5 concentrations in indoor and outdoor settings to understand how unequal exposure to indoor and out-door air pollution impacts indoor air quality among high- and low-income schools in Salt Lake City, Utah. Based on this approach, we found that during atmospheric inver-sions and dust events, there was a lag ranging between 35 to 73 minutes for the out-door PM2.5 concentrations to follow a similar temporal pattern as the indoor PM2.5. This lag has policy and health implications and may help to explain the rising concerns re-garding reduced educational outcomes related to air pollution in urban areas. These data and resulting analysis show that poor air quality may impact school settings, and the potential implications with respect to environmental inequality.

“…In recent decades, the most current and debated topic is undoubtedly that of environmental problems [1][2][3]. In general, the various industrial sectors are certainly increasingly involved in both energy saving and environmental impact issues, especially with regard to emissions and wastewater treatment [4][5][6][7][8][9].…”

The present work aims to analyze the various aspects relating to olive-vegetative waters (OVW) with particular reference to environmental problems. As is known, olive-vegetation waters are one of the most polluting by-products of the oil industry. They are produced in large quantities and have a polluting potential. For this reason, an in-depth and detailed analysis of the production chain is reported up to the correct and lawful disposal of the olive-vegetation waters. The chemical characteristics of vegetation waters are described, with particular reference to polyphenols, which are the most important compounds present in vegetation waters. The treatments, enhancement, perspectives and possible uses in agriculture are reported.
