In a study of 20 workers exposed for IQ-36 years to talc described as pure, at levels ranging from 15 to 35mppcf, no evidence of pneumoconiosis was found. In another study that compared the pulmonary function of workers exposed to either fibrous or nonfibrous talc, it was concluded that although the fibrous form was the more pathogenic type, both talcs produced pulmonary fibrosis no data were presented to document the types of talc involved." ...

Chemo-enzymic methods have been used to prepare a decasaccharide comprising two repeating units of the capsular polysaccharide of the human pathogenic type III group B Streptococcus,and the further decasaccharide 33 has been described. In the area of undecasaccharides compound 32 (n=2) and compound 34 have been described. The largest specific saccharides to have been reported apparently are the dodecamer 35 and the tetradecamer 32 (n=3). ...

In order to ensure the destruction of pathogens, the process of chlorination must achieve certain control of at least one factor and, preferably two, to compensate for fluctuations that occur. For this reason, some authorities on the subject stress the fact that the type and concentration of the chlorine residual must be controlled to ensure adequate disinfection. Only this way, they claim, can chlorination adequately take into account variations in temperature, pH, chlorine demand and types of organisms in the water. While possible to increase minimum contact times, it is difficult to do so. Five to ten minutes is normally all the time available with the type of pressure systems normally used for small water supplies. Many experts feel that satisfactory chlorine residual alone can provide adequate control for disinfection. In their opinion, superchlorination-dechlorination does the best job. Briefly, what is this technique and how does it operate ... 

Pathogenic organisms Bacteria, viruses or cysts which cause disease (typhoid, cholera, dysentery) in a host (such as a person). There are many types of bacteria (non-pathogenic) which do NOT cause disease. Many beneficial bacteria are found in wastewater treatment processes actively cleaning up organic wastes.
