ABSTRACT
p-Chlorotoluene may be released to the environment in emissions and effluents from sites of its manufacture or industrial use, from venting during storage and transport, and from disposal of industrial waste products which contain this compound. If released to soil, p-chlorotoluene is expected to leach slowly with a relatively low soil mobility. If released to water, volatilization, sensitized photolysis, and adsorption to suspended solids and sediments are potentially important fate processes. Based on the vapor pressure, p-chlorotoluene is expected to exist almost entirely in the vapor phase in the ambient atmosphere. Using the Japanese MITI protocol, p-chlorotoluene was found to be resistant to biodegradation because the theoretical biological oxygen demand was less than 30 percent. p-Chlorotoluene is inert to chemical hydrolysis under environmental conditions. Based on the water solubility and log Kow, bioconcentration factors of 45-200 can be estimated for p-chlorotoluene from recommended regression equations.
