Indoor air levels of chlordane and heptachlor following termiticide applications

In 1985, regulations describing the permitted use of these termiticides went into effect (NJDEP 1985). The major focus of these regulations was that (1) a certified applicator must be on site for all termiticide treatments, (2) the use of organochlorine termiticides on interior portions of slabs containing heating ducts was prohibited, and (3) for heating systems located in crawl spaces the ducts must be directed to the outside, and the crawl space must be vented. These regulations were adopted in response to misapplication cases investigated by NJDEP.
