PAHs: An Ecotoxicological Perspective (Ecological & Environmental Toxicology Series)

Polycyclic fragrant hydrocarbons (PAHs), or polyarenes, are one of many biggest and so much structurally various category of natural molecules recognized. excessive probabilities of polyarenes, representing quite a lot of molecular sizes and structural varieties, are found in coal tars and petroleum residues. the most important resources of PAHs are crude oil, coal and oil shale.

1) Mycobacterium tuberculosis. On a total of 42 positive tests including 42 cultures and 65 guinea-pigs, 50 stocks of Koch bacilli have been isolated, 38 on the guinea-pig, 8 on the culture, 4 on both guinea-pig and culture. All these stocks belong to the human type and react positively to the nicotinic acid test. H. only. H, a concen­ tration of very high clinical sigificance; one single stock, isolated at the discharge level into the river from preventorium waste, shows normal sensitivity to this anti­ biotic (50 per cent resistant colonies at 0,1 y/cm2).

In the case of M. Kansasii, the anaerobiosis of the septic tanks seems to foster its growth. (d) Pathogenic Mycobacteria in vegetables grown on dried mud from sanatorium stations with bacilliferous discharge. Various vegetables such as: roots (potatoes, carrots, turnips), aerial plants (cabbage, tomatoes), mixed (leek) are grown on plain mud or on mud mixed with earth. At maturity the vegetable juice is extracted in a special fruit centrifuger, after very thorough washing in sterile distilled water.
