“…It has been shown that in nature, S PM can be washed off of foliage by rain or blown away by strong wind, whereas W PM particles can stick to the surface or penetrate the wax layer and be immobilised (phytostabilised; Jouraeva et al, 2002). Gawrońska & Bakera (2015) suggested that a greater amount of waxes deposited on leaves can be a response of plants to conditions of stress. These authors found higher amounts of waxes on plants growing in an area with more polluted air than on those growing in a clean area.…”

Particulate matter accumulation -further differences between native Prunus padus and non-native P. serotina Received: 14 April 2017; Accepted: 23 June 2017 Abstract: Particulate matter (PM) is one of the most harmful inhaled pollutants. Where pollutants have been emitted into the atmosphere, the most effective method for cleaning the air is through phytoremediation, whereby plants act as biological filters. PM has a negative impact on plants, but knowledge of PM effects on the photosynthetic apparatus is limited. In European forests, species of the genus Prunus L. play a key role in the composition of the forest understory and urban as well as industrial plantings. Shrubs of the native P. padus L. and closely-related invasive alien P. serotina Ehrh. are particularly widespread. Thus, both are good model species in which to study the impact of PM pollution. The aim of this study was to assess the accumulation of PM in the context of leaf morphology and amount of epicuticular waxes on foliage, and the efficiency of the photosynthetic apparatus of P. padus and P. serotina. The study was conducted under controlled conditions using two variants of dust, cement and roadside PM. In addition, we analyzed the absorption of dust by leaves dividing it into three fractions by size (10−100 µm, 2.5−10 µm and 0.2−2.5 µm). Results showed that both P. padus and P. serotina accumulate PM mostly on the surface of their leaves ( S PM), rather than in the wax layer ( W PM). P. padus accumulated higher amounts of PM than did P. serotina. The higher presence of PM on leaves of P. padus resulted in a reduction of the efficiency of the photosynthetic apparatus, manifested by lower rates of photosynthesis and chlorophyll a fluorescence, coinciding with an increased stomatal resistance. A strong negative correlation was found between the amount of PM accumulation and the efficiency of the photosynthetic apparatus in P. padus, but not in P. serotina. We have concluded that alien P. serotina is more tolerant to the conditions of stress caused by PM pollution than is the native P. padus, which may partly explain its success in the invasion in Europe.

“…Indoor air quality (IAQ) is an important environmental health matter that needs to be assessed because people inhale 6-10 l of air per minute, which amounts to 15,000 l per day (Wood et al 2002). According to studies conducted in the last 20 years by the United States Environmental Protection Agency, indoor air is often more polluted than outdoor air, and indoor air pollution has been ranked among the top five risks to public health (Kotzias 2005;Gawrońska and Bakera 2015). The health effects associated with poor air quality contribute to heart and lung diseases (Shin et al 2015).…”

Bioaerosols play a significant role in indoor air quality (IAQ) as they can be the cause of several health problems, including acute allergies and infectious diseases. This study aimed to characterize and compare the microbial air quality of air-conditioned (AC) and naturally ventilated (NV) office rooms in the Upper Silesia region of Poland. The bacterial samples were collected during the late spring season. Culturable bacteria were deposited on the nutrient media on Petri dishes to investigate the viable-culturable count (VCC) of bacteria and bacterial community structure using a Biolog GEN III system. In total, 12 species of bacteria were identified, with the most isolated Macrococcus equipercicus, Micrococcus luteus D, Staphylococcus xylosus (indoor), and Bacillus species (outdoor). The indoor mean concentrations of bacterial aerosol ranged from 10 2 to 10 3 CFU m −3 , below Polish proposals for threshold limit standards in office buildings. The indoor-to-outdoor (I/O) ratios indicated that studied air pollutants in the office rooms originated from the indoor air. These results, together with community composition of bacteria, indicate that most of the bacteria present in the studied office building were relatively fresh and of human origin. Multi-antibiotic resistance (MAR) tests showed that the most antibiotic-resistant features were present in Macrococcus species. The office building exposure dose (OBED) and mass median aerodynamic diameter (MMAD) of bacteria aerosol were estimated. The highest value of OBED over the study period was obtained for staff working in offices with natural ventilation (141 CFU kg −1 ), in contrast to the value for staff working in offices equipped with air conditioning (about 100 CFU kg −1 ). The MMAD of viable airborne bacteria was higher in AC offices (2.4 μm) than in NV offices (2.2 μm).

“…The multiple boxesmodeling was used in a laboratory-type test to describe the performance of planting on the cleaning of indoor air. Although the earlier laboratory studies have demonstrated the ability of bioremediation technologies to remove VOCs (Kim et al, 2008;Xu et al, 2010;Xu et al, 2011;Dela Cruz et al, 2014;Gawronska and Bakera, 2015;Pandey et al, 2016;Hong et al, 2017), no experimental field-study has been made to investigate the potted-plant can bring about significant reductions of VOC pollution in the real environments. Our study might provide an accurate and relatively accessible platform for the public, interior designers and engineers to determine if the health risks of VOCs in their building space.…”

Formaldehyde is the most common volatile organic compound (VOC) emitted from household materials and is associated with many health risks, including sick building syndrome. A potted Hedera helix was used as an air purifier to remove the gaseous formaldehyde. Development of a test platform is necessary to evaluate the indoor performance of air cleaning protocols. The box modulation with a novel volatile pollutant-emitting source was applied in an air quality monitoring experiment to mimic a non-ventilated workplace. The environmental conditions and the pollutant concentrations in the air were measured in real time, and the monitoring data was uploaded to cloud storage media by a wireless technique. Compared with natural dissipation, our results demonstrate a 70% decrease in the required time to achieve 1.0 ppm of gaseous formaldehyde using the biological purifier. In addition, the effect of photo-regulation was not significant in the use of potted plants to remove gaseous formaldehyde. Our study provides an accurate and available platform for the public to determine the health risks of VOCs in their buildings.
