Indoor health is the resultant of exposure to all building materials, the contents of room equipment, occupant activities, and the ability of the space to eliminate negative effects on life. This paper adequately describes sources of pollutant exposure, pollutant movement, biological processes, health impacts, all of which can cause Sick Building Syndrome (SBS). Furthermore, indoor depollution measures to counteract SBS need to be carried out at the stages of building design and construction. Based on the interests and needs, here it is necessary to propose a certification of potential SBS at the design and construction stages. Thus, SBS responsibilities can be proportionately distributed to designers, contractors, and building users.

In addition, aerosols that are directly absorbed through inhalation can have a negative impact on human health. Meanwhile, the ability of air to reduce the level of pollution is the deconcentrating of pollutants through abiotic mechanisms in the form of distribution, dilution, precipitation and washing when it rains. To strengthen the abiotic approach, this study aims to develop a biotic strategy by preparing plants capable of deconcentrating black carbon. The research method is based on a literature review, which specifically addresses the issue of black carbon. Literature is collected from the Mendeley platform and enriched through resource searches in open access journals. The results obtained are cleaning priorities for the closest source of aerosol generation, plant placement in priority areas, selection of plant species, intensification of vegetation quality...

Therefore, this study was conducted to evaluate the regressors and their operating parameters affecting the double anode chamber–designed dual-chamber microbial fuel cell (DAC-DCMFC) performance. Its primary design consists of two anode chamber compartments equipped with a separator and cathode chamber. The DAC-DCMFCs were parallelly operated over 8 days (60 days after the acclimation period). They were intermittently pump-fed with the different organic loading rates (OLRs), using chemically enriched sucrose as artificial wastewater. The applied OLRs were adjusted at low, medium, and high ranges from 0.4 kg.m−3.d−1 to 2.5 kg.m−3.d−1. The reactor types were type 1 and type 2 with different cathode materials. The pH, temperature, oxidation-reduction potential (ORP), optical density 600 (OD600), chemical oxygen demand (COD), and total organic carbon (TOC) were m...
