An Interpretation of all th prwaant data avallabla lndloataa that thaaa lowor chlorinated bi phenyls are not preeent in the general envlromeant aa a contaminant. When you dlaouaa the ioaodiats toxic afreet of camponenta of hydraulic fluids you gat involved in a diaouealon of the phyaleal and ohaaioal chareotariatloa of thaaa ooupounda. for oxaaplo, the solubilities of the PGB's lnareaae aa the peroent of ohlorlnation daoroaaaa. Those compounds are eoluble in the range of 50-150 ppb in water at roon tanparatura. Whan thaaa mmteriala are taatad on aquatic niganlawa aueh aa flah. the toxicity affaet has aueh to do with whether the Material la aaailelfled and nany other faotora. In the natural environment, ainoa these aateriala are quite a bit heavier than water, they will aink to the bottom and ean beeona a threat to bottou feeders and benthio plankton. On the other hand if a note soluble hydieulie fluid eenponent were released to a natural water environment (in sufficient aoneantratlon) it could pose a taalo threat to the larger organisms occupying this environment such as sport fish. It is also possible that soluble hydraulic fluids which are readily degradable biologi cally ean pose a similar threat through oxygen labalanoe in the receiving stream. This discussion points out the faot that any hydreullo fluid oonponent ean la sufficient concentration if discharged te a receiving water course be a threat to the biological stability of that water course, we reoemasnd to our customers that they sake sure that hydraulic fluids do not enter receiving water courses in concentration sufficient to cause harm. Since most hydraulic fluids including our cun are blended fluids nade eg of several components, an intelligent approach to pollution abatement is needed where it is possible for these fluids to be discharged. Where fluid components are lost to the receiving stress. It is neeessary to install equipment on the waste straaa to remove them. In most eases s settling basin or trap which la periodically cleaned will suffice. Such a device nakea it possible to oolloet and reproeees these fluids. Such equipment should be capable of collecting the aateriala that fall to the bottom aa well aa skimming tbs ooaponsets that float on tha top.
