High concentration of particulate matter (PM) threatens public health and the environment. Increasing traffic in city is one main factors for increased PM air. Urban green spaces play an important role reducing PM. In this study, leaf surface in-wax (sPM wPM) accumulation were compared 11 plant species widely used landscaping South Korea. addition, biochemical characteristics leaves (ascorbic acid chlorophyll content, pH, relative water content) analyzed to determine air pollution tolerance....
Particulate matter (PM) is the most dangerous form of air pollution and known to cause severe health problems humans. Plants as biological filters can reduce PM in urban areas by accumulating on surface epicuticular wax leaves. The present study determined amount (large (10–100 µm) coarse (2.5–10 µm)) collected 10 plant species from two sites (urban forest roadside) Cheongju City, South Korea. Selected leaf traits (chlorophyll a (Chl a), chlorophyll b b), total (TChl), carotenoid, relative...
Particulate matter (PM) is the most dangerous type of air pollutant and harmful to human health. Plants can be used as a biofilter remove PM from atmosphere improve quality. In this study, we pollution tolerance index four leaf traits five different plant species commonly in landscaping Korea determine which plants are best suited roadside areas spring, summer, autumn. We found that concentrations impacted amount accumulated plants, with increased accumulation during periods environmental...
Particulate matter (PM), an extremely serious type of air pollution, leads to numerous human diseases. Mitigating PM in the urban city, where resident density has been increasing, a major challenge. The increase residents increasing traffic, primary source areas. Plants play important role reducing and maintaining ecological balance. For some Asian countries, such as Korea, with differing seasons environmental conditions, accumulation plant survival are greatly impacted by conditions. In...
Background and objective Particulate matter (PM) is the most dangerous form of air pollution, causes many diseases. Plants act as bio-filters to help reduce PM in atmosphere. also influences growth plants, so selecting suitable plant species for specific environmental conditions very important. The pollution tolerance index (APTI) was used determine level each pollution. purpose this study various order identify that can be grown polluted environments; achieved by evaluating APTI plants....
Background and objective: Since people spend 70-80% of their time indoors, the quality indoor air has become a crucial factor in overall health. Therefore, poor can have significant adverse effects on our well-being. Common pollutants are particulate matter (PM) carbon dioxide (CO2). Plants remove PM CO2 through photosynthesis process leaf surfaces, regulate temperature humidity air. By analyzing reduction four broad-leaved evergreen plants, this study aims to provide data for purification...
Particulate matter (PM) is the most dangerous air pollutant that adversely affects health. Increasing PM in urban areas a big problem must be solved. This study analyzed amount of accumulated on plant leaves, as well leaf traits contribute to accumulation, determine plant’s ability accumulate and impact plants. Scanning electron microscopy (SEM) energy dispersive X-ray (EDX) analysis were used quantitatively assess metal concentrations particles had samples. Eight common species grow...
Indoor air quality (IAQ) directly affects human health. The increase in PM and CO2 concentration indoors caused an the prevalence of sick building syndrome (SBS) symptoms. Plants could contribute to reducing particulate matter (PM) CO2. This study identifies most efficient evergreen plant species for improving indoor by assessing ability five different indigenous Korean reduce regulate humidity temperature under environmental conditions acrylic chambers. clean delivery rates (CADR) were...
Background and objective Particulate matter (PM) has a serious impact on health. Recently, studies are conducted to reduce PM in an environmentally friendly way using plants. This study investigated the physiological responses of plants their ability remove by continuously spraying different sources (loam, fly ash, carbon black) four native plant species, such as <italic>Iris sanguinea</italic>, <italic>Pteris multifida</italic>, <italic>Vitis...
