5 Lichens as bioindicators of air pollution
Lichens are considered the result of a symbiotic association of a fungus and an alga. More precisely the term “alga” indicates either a Cyanobacteriae or a Chlorophyceae; the fungus is usually an Ascomycetes, although on rare occasions it may be either a Basidiomycetes or a Phycomycetes. In this association, the alga is the part that is occupied with the formation of nutrients, since it contain...
متن کاملEpiphytic Lichens: Their Usefulness as Bio-indicators of Air Pollution
Lichens are used as effective monitors to detect low-level air pollution which may affect different flora and fauna communities. Epiphytic lichens have been widely recognized as effective eco-friendly bio-monitors for detection of metal deposition on trees, rocks and bare ground. This article is concerned with the use of lichens in bio-monitoring of air pollution, how the lichens do recognize a...
متن کاملA new method to assess air pollution using lichens as bioindicators.
Lichens are increasingly used worldwide as air quality biomonitors because they are efficient, easy and cheap, but validation studies of the methodology are scarce. Three foliose lichen biomonitoring methods were compared by field tests (in the tropical urban habitat of San José, Costa Rica) and laboratory simulations: (1) the 100 uniform squares template traditionally used in North America, (2...
متن کاملMobile phones as monitors of personal exposure to air pollution: Is this the future?
Mobile phones have a large spectrum of applications, aiding in risk prevention and improving health and wellbeing of their owners. So far, however, they have not been used for direct assessment of personal exposure to air pollution. In this study, we comprehensively evaluated the first, and the only available, mobile phone-BROAD Life-equipped with air pollution sensors (PM2.5 and VOC), to answe...
متن کاملBiochemical changes of Conocarpus erectus (combretaceae) in response to gas refinery air pollution as an air pollution indicator
Environmental pollution consists of different types of pollutants in air, soil, and water. Due to the fact that plants can respond to environmental pollution, they can be used as bio-indicators for environmental monitoring. Air pollution in areas with oil and gas refineries nearby is an important problem. This study aims to survey the effects of gas refinery air pollutants on Conocarpus erectus...
