1,4 Dichlorobenzene

1,4-dichlorobenzene (1,4-DCB or p-DCB): 1,4-DCB is reasonably anticipated to be a human carcinogen, and has been shown to cause kidney and testicular cancer in rats. It also has been shown to cause reduced lung function and increased asthma rates in humans. p-DCB is used as a pesticide and a deodorant, most familiarly in mothballs in which it is a replacement for the more traditional naphthalene or in air “fresheners”.
