室内空气中真菌污染是当今一个非常普遍的问题。它的存在给室内居住者带来很多问题,业主或经理,因为它影响的室内空气质量(IAQ)感染建筑和与健康有关的症状包括头痛、哮喘、过敏和刺激效果,呼吸问题,真菌病(真菌疾病)和其他一些非特异性健康问题[1]。室内空气品质的定义是在一个封闭的建筑内的空气质量，导致舒适和健康的居住者[2]。这是一个主要问题，因为在发达国家和发展中国家，例如马来西亚、新加坡、印度尼西亚和其他国家，大多数人的大部分时间是在室内办公室、工厂、家庭或教育大楼中度过的。据估计，全球约有10%的人和5%的工业化国家人口对真菌过敏[3,4]。许多动物研究证实，真菌毒素与致癌、免疫抑制和其它性质的[5]有关。真菌释放微小的孢子漂浮在空气中，然后落在其他地方繁殖。当它们落在潮湿的表面时，孢子可以形成新的菌落。如果这些空气中的真菌孢子或真菌毒素被吸入支气管和肺泡，它们将被分解，人体因此暴露于初级和次级代谢产物[6]。吸入暴露可导致急性肾衰竭、上呼吸道损伤和中枢神经系统损伤。因此，这些真菌的存在是无法容忍的室内环境。

Indoor airborne fungal contamination is a very common issue nowadays. Its presence brings a lot of problems to indoor occupants, building owners or managers as it affects the indoor air quality (IAQ) of those infected buildings and it has been associated with unhealthy symptoms including headache, asthma, allergy and irritant effects, respiratory problems, mycoses (fungal diseases) and several other non-specific health problems [1]. IAQ is defined as the air quality within an enclosed building that leads to the comfort and healthiness of its occupiers [2]. It is a major concern as most people in the developed and developing countries, such as Malaysia, Singapore, Indonesia and others, spent most of their time indoor in either offices, factories, homes or educational buildings.It has been estimated that approximate 10% of people worldwide and 5% of the population in industrial countries have fungal allergies [3,4]. Some fungi such as Aspergillus versicolor and Stachybotrys chartarum are able to produce mycotoxins and have been associated with sick building syndrome [1] Many animal studies have confirmed that mycotoxins are associated with carcinogenic, immune-suppressive, and other properties [5]. Fungi release tiny spores that float through the air and land on other locations to reproduce. When they settle on moist surfaces, the spores can form new mold colonies. If these airborne fungal spores or mycotoxins are inhaled into bronchia and alveoli, they will be lysed and the human body thereby exposed to the primary and secondary metabolites [6]. Inhalation exposure has been suggested to cause acute kidney failure, damage of the upper respiratory tract, and central nervous system damage [7]. Thus, the existence of these fungi is intolerable in indoor environment.
