The study on the influence of air pollutants (coal dust) on lung of wild animals kept in Chang-gyeong Weon zoological and botanical gardens was carried out 2-year period from June, 1973 to June, 1975.
The micro and macro findings of the anthracosis of 231 captive wild animals were studied.
The obtained results were as follows:
1. The cases of anthracosis were found in 170 heads (73.6%) out of total 231 heads and 3.9% of 170 animals showed high degree of contamination and rest of them showed low or mild degrees.
2. 89.3% of 28 Mammalia, 71.5% of 200 Aves and 100% of 3 Reptilia had the anthracosis. Among the cases of anthracosis, the high degree of anthracosis were found in 3.5% of Mammalia and 4.5% of Aves.
3. The Animals showed the tendency of higher degree of lung contamination according to the progress of breeding period. 53.8% of the animals with less than 1 years breeding period has anthracosis, and 87.2% of the animals with more than 2 years of breeding period had the anthracosis.
4. Significant differences according to the breeding places were noticed. 69.6% of out-quarter breeding animals had the anthracosis and 74.5% of in-quarter breeding animals had anthracosis.
5. Most of the anomals examined showed microfindings of anthracosis and 5 heads showed macrofindings.
