Scions <br /> AU samples were handled and analyzed in accordance,with EPA mo-hods as voted on the <br /> laboratory doctnontatiion. <br /> V. FMITiGS <br /> A. (imml <br /> AM reported chou;k ls, egWptiftmut and by-products of the clandestine activities were <br /> removed by law enfoncernent prior to the site inpection. Labomtory analysis o'' the <br /> submitted samples indicated the pre==of Metbamplwoumine (via method HPLC-U V by <br /> USP # 24) as well the precursor Naphthalene (via EPA; method 6260H) in the surFdce <br /> wipe samples collected_ <br /> B. pH <br /> Samples wme ar}alynd for pH to assess acid and aikalme contamination associated with <br /> the use-of correaive chemicals. The pH scale is a logarithmk scale, ranging from 0 to s 14, <br /> used to characterize corrosivity. A pH value less than 7 suairsts an acidic mat--,da, <br /> wherew a pH greater tlaa 7 is indicative to caustic (basic) materk s. The sample-r�sult <br /> was 8.01. The sanVlc results appear to be only slightly caustic. <br /> C. Phosphorous <br /> PhoWborous;bas ens esmbEsbed exposum Un-dt of O.1 milligrams peer cubic meter (ingt3) . <br /> of air. Along with iodide, it is cspable of producing eye, dein, nose and respiratory tract <br /> irritation along with cheat tightness, headachms, stomach pain, birth defects,jaundice and <br /> kk1ney aav%W. The rccog=d target organs are eyes, skin, respxatory system, central <br /> nervous sli, liver, kidneys, blood and cardiovascular system.
