Resumo(s)
Seven years of aeromycological study was
performed in the city of Funchal with the purpose to
determine the anamorphic spore content of this region
and its relationship to meteorological factors. The
sampling was carried out with a Hirst-type volumetric
spore trap following well-established guidelines. A
total of 17,586 anamorphic fungal spores were
recorded during the studied period, attaining an annual
average concentration of 2931 spores m-3
. Anamorphic fungal spores were observed throughout the year,
although the major peaks were registered during
spring (April–June) and autumn period (September–
November). The lowest spore levels were recorded
between December and February months. Over 14
taxa of anamorphic fungal spores were observed with
Cladosporium being the most prevalent fungal type
accounting for 78 % of the total conidiospores. The
next in importance was Alternaria (5.4 %), Fusarium
(4.7 %), Torula (3.9 %) and Botrytis (1.9 %). Temperature was the meteorological parameter that
favoured the most release and dispersal of the
conidiospores, whereas rainfall revealed a negative
effect. Despite the low concentration levels found in
our region, the majority of the fungal types identified
are described as potential aeroallergens. This study
provides the seasonal variation of the conidiospores
and the periods when the highest counts may be
expected, representing a preventive tool in the allergic
sensitization of the population.
