In the production of chlorine from brine, caustic is produced. What is to be done with this caustic Is it to be neutralized and discarded If so, what acid is to be used and where is the resulting salt to be dumped Will this cause pollution problems Maybe there are no federal or state pollution laws being violated, but the fastest way to get restrictive controls is for the chemical companies to ignore the public s feelings. On the other hand, if the caustic is to be purified and sold, how pure should it be, and can the amount produced be sold When the brine also contains some magnesium salts and bromides, then the scope must indicate if magnesium and bromine are to be recovered, and, if so, what their respective purities should be. 

The Elements.—Downs and Adams have reviewed the chemistry of chlorine, bromine, iodine, and astatine/ The role of fluorine in our environment and the use of lichens as monitors for air pollution have been discussed by Dobbs/ Particulate rather than gaseous fluorides were shown to be the pollutants in the vicinity of one aluminium refining plant/ Bronchitis, pneumonia, nervous disorders, and skin diseases were said" to occur more frequently in workers at a Russian AIF, production plant than in a control group. 

Fish with high fat contents is an important source of long-chain n-3 polyunsaturated fatty acids (PUFAs) in the human diet, in particular for docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) (EFSA, 2005). On the other side, a wide range of environmental contaminants have been reported to be accumulated in fish that can pose a potential human health hazard (Leonard, 2011). Major contaminations include the different OCPs, PAHs or the widely distributed persistent organic pollutants (POPs) with the polychlorinated biphenyls (PCBs) and the flame retardants compound class of the polybrominated diphenylethers (PBDEs). Also farmed fish can significantly contribute to dietary exposure to various contaminants due to the use of land sourced fish feed. A multi method for efficient control of fish and fish feed for various groups of contaminants from PCBs, OCPs, BFRs (brominated flame retardants) and PAHs is outlined in the following analytical procedure published by Kamila Kalachova et al. (Kalachova et al., 2013).
