Limited data availability, chemical

Brominated HAAs are formed in waters that contain bromide. There are very limited data available on the toxicity of these chemicals. There are no studies on the health effects of brominated HAAs in humans. No formal reports have been made of carcinogenic or mutagenic effects of brominated HAAs. Metabolism of brominated HAAs has received little attention. 

Properties. Limited data are available for the types or grades of commercial agar which is usually in the form of chopped shreds, sheets, flakes, granules, or powder. The official specifications for agar are provided in the USP (12) and the Food Chemicals Codex (13). 

When no Kc< or HTU data are available, their values may be estimated by means of a generahzed model. A summaiy of useful models is given in Section 5, Table 5-28. The values obtained may then be combined by the use of Eq. 14-19 to obtain values of Hoc and Hql-This procedure is not valid, however, when the rate of absorption is limited by a chemical reaction.
