Regulations restricting uses of PCBs are being Introduced In Canada. Because PCBs and PCTs were formerly widely used In manufactured products, the Environmental Protection Service required Information on their occurrence In a range of recently manufactured goods. A large part of the output of manufacturing Industries Is disposed of at municipal solid waste facilities. Samples of composited pulverized garbage were available from cities across Canada and were analysed for PCB and PCT. The Ontario Research Foundation selected the products and analysed the products and the garbage samples under contract. The two reports form the substance of this document. Because only one sample of each selected brand and only a limited number of brands were analysed and because the significance of trace quantities of PCBs and PCTs Is unknown, the brand Identification, the manufacturer's name and the name of the retail outlet Involved have been deleted. Where duplicated analyses were carried out, both results are Included. The results In this report show that the levels of PCB In this range of samples were low but Indicate that PCBs are coamonly present in many products In everyday use. An extensive survey of PCB and PCT content of food-packaging materials undertaken In Canada In 1972 (JAOAC 56:999-1001. 1973) showed levels generally below 1 ppm but a substantial fraction of the samples contained 1 to 10 ppm; some were above 10 ppm. The limited survey reported here found only one sample (cork wall tiles) that contained more than 1 ppm PCB. Both PCB and PCT were detected in every garbage sample with the exception of one sample from Edmonton - West End. This limited number of results suggests that PCB and PCT levels, as expected, are very variable.

The main purpose of the survey was to determine If commercially available materials are currently contributing PCBs (polychlorobiphenyls) to the environment. Within the Initial limit of 100 samples, we attempted to cover the widest possible range of materials which were Judged more likely to contain PCBs. The samples were purchased during December 1976, and in January 1977, ve began the analyses as well as methodology work on materials which ve had not analysed previously. Because of the very vide variety of materials, even within the same product category, several different methods were used for the analyses. PCTs (polychloroterphenyls) were not requested, but ve endeavoured to Include it in the analyses, assuming that the PCB extraction and cleanup methods would be adequate. Method^ofAnal^rees Following preliminary methodology and recovery studies, the samples were extracted and deaned-up according to the following procedures: (1) Sample (3 g) weighed accurately In a 50 ml volumetric flask and made up to volute with hexane. Mixed well and pipetted 5 mis onto a 22 deactivated Plorlsil column for cleanup.

Concentrated on steaa bath using Snyder coluan and put through 2Z deactivated Florisil coluan. The 21 Water-deactivated Florisil Method for Cleanup and Separation of PCBs Reaaent:- Florisil, regular grade, 60/100 mesh (Travelon Oil Co.). Heated at 300*C overnight, 2Z water added. Procedure:- Pack 1" diameter glass wool plugged coluan with 6" of 2Z deactivated Florisil. Settle coluan by gentle tapping. Add 0.5" sodium sulphate. Rinse colun with 100 ml hexane. Add 5 al hexane to concentrated sample extract. Four sample solution onto column and elute with *150 al hexane, using eluant to rinse flask, onto colun. (The exact volume of hexane is determined for each new jar of 2Z deactivated Florisil.) Eluant should pass through at a rate of 5 ml/min. Concentrate to Incipient dryness, add 5 al hexane and Inject.

Reaulta^sn^^o^Mnts The PCB, PCT results of the first three sample categories (oils and lubricants, plastics, papers) are given In Table 1. The sensitivities and recoveries of the methods are summarized in Table II. The PCB, PCT levels reported have not been corrected for recoveries which were generally essentially complete. Recoveries were not carried out for PCTs but from previous experience, these usually follow the PCB recoveries closely. In general, the Soxhlet extraction gave slightly higher values than the shaking and blending methods, but it also showed somewhat higher background from coentractives. Figure 1 shows a typical PCB gas chromatogram of a sample and the reference standard against which it was quantitated. The method of quantitation is by reference to the peak heights of three major peaks and averaging the results. LMRievdm Attach. L.M.

Our earlier report. ORP 77-1. described the purpose of the survey, analytical methodology used, as well as the PCB and PCI results on 45 of the saspics. Our present report gives the residue results for the renalnlng 55 aanple materials and for 21 garbage samples collected across Canada. Methods of Analyses The analytical methodology Is described in report ORF 77-1. This Included twenty different extraction and cleanup schemes. The following two additional methods have heen used also: (21) Sample (2.0 g) weighed accurately and mixed well with 25 g Plorlsll (regular grade, heated at 300*C overnight). Packed column with 3 g Plorlsll and added Plorlsll/sample mixture. luted with 200 ml 5Z water/acetonitrile and allowed eluant to pass through column at a fairly steady pace (=5 ml/mln). Shook eluant with 100 ml hexane. Added 600 ml water and 10 ml saturated sodium chloride and shook vigorously. Washed hexane layer twice with 100 ml water and filtered through sodium sulphate. Concentrated and put through 2Z deactivated Plorlsll colon. (22) Sample (5.0 g) extracted on Soxhlet with hexane for 3 hrs. Concentrated and put through 2Z deactivated Plorlsll colian. MOMS 011440 - 2.2 - Results and Commants The PCB, PCT results on the final five sample categories (paints, etc., waxes, soaps, etc., building materials, adhesives) are given in Table 1. The results on the garbage samples are presented In Table II. It should be emphasized that quantitation of the PCBs is by reference to the peak heights of three major peaks and averaging the total value obtained with each peak. The values obtained for Aroclor 1242 or 1248 as reference, should be added to the 1254 or 1260 or the 1:1 mixture of 1254/1260 to give a total PCB content. Note, however, that because of overlapping of the major peaks, l.e. response from the same isomers, 1242 and 1248 are not additive; also 1254, 1260 and the 1:1 mixture of 1254/1260 are mot additive.

Love and Associates Ltd., as directed by EPS. The samples were extracted and cleaned-up by method 22. It was difficult to get fully homogenous samples and this Is reflected In the differences betveen duplicate analyses. (b) The PCB reference used was dictated according to the GC pattern observed. The 1254/1260 indicates a 1:1 mixture of Aroclor 1254/1260. The p.p.m. values are given on "as received" basis, and the commas Indicate duplicate values. (c) Aroclor 5460 was used am the PCT reference. (d) This sample showed Dips at Hit of 16.7 (larg^ and 18.8 (large). Note that the PCB values should be added to give a total PCB content.
