At the 15 targeted nephelometer locations, plus an additional 14 locations near the burns, trained local personnel placed passive samplers (which did not require a field operator or electricity) to measure particulate matter (RJ Lee Group, Monroeville, PA) and naphthalene (SKC Product Code: 575-003, Eighty Four, PA) for 24 to 120 hours and then sent the samplers to our laboratory for analysis.
Investigations included: Total cholesterol, total triglycerides, LDL-C and HDL-C using enzymatic colorimetric methods, ApoA1, Apo B100 were evaluated using a Behring nephelometer. Different therapeutic modalities were offered and reassessment of laboratory tests was done every three months.
