2. Expressing milk for testing may cause harm to mother and might reduce fertility this suspicion was not limited to breast milk but testing of all bodily fluids. There was generally also a high level of apprehension from the mothers even after they were briefed by the nurses in charge at the clinic. Home visits were arranged for the mother who were unable to attend the clinic. There were also various challenges among those who participated in the survey. These problems included: 1. Participants who took the samples bottles home them decided that expressing was too much of a burden and could not continue. 2. Participants would agree to participate but would later discontinue as an older relative usually the participant‟s mother or grandmother would discourage the mother citing reasons relating to superstitious belief. 3. Some participants after agreeing for the samples to be collected at home, would then leave the home for some unknown location and then could not located or contacted. Sample collection occurred from mid November 2010 to the first week in January of 2011. Sample classification was done as described in Table 1 below.

Training Programme: All samples were analyzed by our trained analysts. However, UNEP arranged to send two experts from Spain, Drs. Benin and Encara to visit our laboratory and trained two of our analysts, Dr. Raymond Reid and Ms. Sherin Whyte, on the application of GC/MS method to detect trace amount of POPs and PCBs in breast milk and air samples. The training was quite helpful for the analysts. Analytical Support: Initially it was promised by the Regional coordinator and UNEP that all the glassware and chemicals will be sent by the UNEP and accordingly a list of requirements was sent to the UNEP. Unfortunately, except GC column and sample bottles no other items were arrived. It caused an enormous delay in starting the project and also because of shortage of glassware, specifically Soxhlet apparatus for extraction of POPs the analyses took us longer time than anticipated. Air Sample (PUFs) 2010-2011 Section 1 Air sample monitoring was done using polyurethane foams (PUF). The exposures of the PUFs were done in four (4) rounds between August 26, 2010 and July 8, 2011 (see details in table 1 below). There were eight (8) PUF samples per round, four (4) of which were analysed for Persistent Organic Pollutants (POPs), dioxins and furans by the designated local laboratory (Pesticide Research Laboratory, PRL) and the other four (4) samples were analysed by a designated laboratory in Spain for the same parameters. The Standard Operating Procedure (SOP) used for the analysis of the PUF samples and the results are shown section 2 and 3 respectively.
