THE Office of Disaster Preparedness and Emergency Management (ODPEM) said last night that environmental conditions along the Portmore toll road have normalised as an odour which caused a lockdown of the highway Thursday has dissipated and therefore poses no immediate danger to the public.

"Motorists may proceed freely along the main thoroughfares of Port Henderson Road and the Portmore toll road but are still advised to take precaution," ODPEM said last night.

And while ODPEM had not yet identified the source of the odour, it said samples of sand and sea water were collected by the National Environment and Planning Agency (NEPA) to be analysed over the coming days, while additional air-quality will be monitored over the next seven days.

Emergency response teams from the ODPEM, NEPA and the police yesterday conducted a reconnaissance tour to ascertain the type of substance which has been emitting fumes and its source. The teams visited the Portmore Toll Plaza, Fort Augusta Correctional Centre, sections of the Port Henderson coastline, Kingston Container Terminals and Kingston Wharves.
