Chlordane is widely used in Japan to control termites. A diffusion sampler monitoring system was developed to quantify trans- and cis-chlordane, trans- and cis- nonachlor, and heptachlor in indoor air. These compounds are the main components of technical chlordane. Concentrations were determined over a 1-yr period in five houses in Japan. Outdoor chlordane concentrations were also monitored continuously. Results indicated that chlordane in indoor air originates from indoor residues by volatilization. Highest concentrations were found in July, and all chlordane compounds showed similar seasonal variations. Indoor chlordane concentrations were detected both in houses where termite control was practiced and in houses made of pretreated wood products.
