INDUSTRIAL AND URBAN CONTAMINATIONDahia residents gathering corrugated iron from building rubbleof 150 μg/m 3 . Therefore, appropriate mitigatorymeasures to control the dust problem, and theassociated health impacts, should be implementedas a matter of priority.In sum, the waste management issues included,but were not necessarily restricted to:huge volumes of demolition waste, composedprimarily of :– concrete rubble;– steel beams; and– aluminium sheeting;numerous derelict motor vehicles; andlocalized areas of soil and rubble contaminatedwith fuel oil.Contaminated landThe presence of many small generators in therubble is a common problem. According toresidents, these generators are operated in nearlyevery building by one or more of the residents,and the energy generated is sold as a backupduring the frequent power black-outs.In front of one of the generator rooms, a smallamount of machine oil had seeped into the ground.In addition, the whole room smelled of diesel fuel andoil. A sample was collected for laboratory analysis.Table 21.Parameter /Sample IdentitySample no: 44B-CL-01Unit44B-CL-01DutchInterventionValueSample depth bgs m 0.0EPH (DRO) (C10-C40) mg/kg 17,442 5,000PAH by GCMSNaphthalene μg/kg 1,655 –Phenanthrene μg/kg 4,946 –Anthracene μg/kg 602 –Fluoranthene μg/kg 903 –Benz(a)anthracene μg/kg 217 –Chrysene μg/kg 565 –Benzo(k)fluoranthene μg/kg 130 –Benzo(a)pyrene μg/kg 174 –Indeno(123cd)pyrene μg/kg 444 –Benzo(ghi)perylene μg/kg 556 –PAH Dutch List 10 Total μg/kg 10,192 40,000XAcenaphthylene μg/kg 460XAcenaphthene μg/kg 723XFluorene μg/kg 2,213XBenzo(b)fluoranthene μg/kg 261XDibenzo(ah)anthracene μg/kg 278XPyrene μg/kg 2,151PAH 16 Total μg/kg 16,278 –The analysis of the sample shows that the substancespilled in front of the generator was diesel.

The size of the spill (approximately2 m²) and the relatively good condition of thefuel drums inside the generator room led to theconclusion that:• United Nations Environment Programme • United Nations Environment Programme • United Nations Environment Programme •89
