Air-borne microfungi population over Beijing in 1956-1967 and 1979-1981 were analyzed and compared. The population density has increased 350% from 1967 to 1981. This is probably due to the reason that air dusting is getting heavier in the past 24 years. The dominant species of the air-borne fungi are Cladosporiam, Alternaria, Aspergillus and Penicillium. In summer time the density of the Aspergillus population increases considerably, while the largest number of the identified genera appears in winter....

Air-borne microfungi population over Beijing in 1956-1967 and 1979-1981 were analyzed and compared. The population density has increased 350% from 1967 to 1981. This is probably due to the reason that air dusting is getting heavier in the past 24 years. The dominant species of the air-borne fungi are Cladosporiam, Alternaria, Aspergillus and Penicillium. In summer time the density of the Aspergillus population increases considerably, while the largest number of the identified genera appears in winter. This is probably due to lack of the plant coverage at that time. On the other hand, autumn is the cleanest season in a year because of its better plant covering, and less air-borne dust.

比较了1957年和1981年两次对气挟真菌的调查结果,证明北京上空气挟真菌的密度由1957年至1981年增加到原来的350%,这反映出空气挟尘量的急剧增加。经鉴定得知:优势菌种有四种即Cladosporium、Aspergillus、Alternaria和Penicillium,从全年的累计菌的群体比例上看,夏季Aspergillus密度增高。从已鉴定的真菌的属的数目上看,冬日菌种最多,这显然是因为植被枯萎、风砂严重所致,秋季是最清洁的季节,这和植被覆盖好、风砂少有关。

Poar this exiraet into a silira gel column clute with C6H6 -CH 3COOH(9 : 1) and collect the grcenish yellow fluo-rsceat eltiate under UV lighi. This cluate is coneentrated to a small volume, and spotied on the preparing TLC silica gel plates, developing with Toluenc-EtOAc-90% Formic acid(5 : 4 : l). Under UV light, remove the greenish yellow fluorescent zones from the plates and elute on a ehroma-tographic column with CHCI3. Tie eluate is evaporated on steam hath under N2 condition to dryaess, and crystallized from henzene. The pro-duct is colorless crystalline with m.p. 89-91℃. It is identified as ochra-toxin A by UV, IR, NMR, Ms spectra and other methods.

Having been extracted, concentrated and separated with thin layer, the aspergillus flavus B1 of samples is scanned on the thin-layer scanner. Then, the content of AFB1 of the samples can be precisely calculated by the linear relation of the content as well as the peak area between AFB1 of the samples and the standard. The paper shows the optimal condition of the measurement of AFB1 with the method of thin-layer scanning based on a series of tests.It also explores the ways to apply this method to the measurement...
