During cruise at FL340 we received a L BLEED DUCT warning. The First Officer was already flying; so I transferred control of the radios to him; told him to request a lower altitude; and ran the QRH. I ensured the Right bleed was selected per the procedure; however; I looked at the ECS (Environmental Control System) page and saw the right bleed valve had closed and the associated R ENG BLEED caution message had appeared. I double checked the procedure; and confirmed with my First Officer that we had completed it correctly. The cabin altitude had started climbing and I made the decision to make an emergency landing at a nearby airport. We donned our masks and complied with the emergency descent procedure. Once we reached 10;000 feet; we removed our masks. We noticed an acrid smell that burned the back of my throat (and persisted even after we had secured the airplane). We briefed for the visual approach and landing. The L BLEED DUCT warning message was still present and as a precaution I requested the emergency vehicles follow us to the ramp. Since we would land overweight I performed the landing. My First Officer noted our descent rate at touchdown of 200 feet per minute. As we taxied clear of the runway; the warning message finally went out. As we approached the gate; one of our flight attendants called and reported a thick haze and bad smell in the cabin. As a precaution; we elected to do an expedited deplaning just short of the terminal. The fire department was present and confirmed the odor. Later; while talking to a ramp agent; she also asked about the odor; that it made her lightheaded and burned her throat. In debriefing; the flight attendants reported that a passenger pulled roughly on a mask which caused the panel to fall on his face; and resulted in a bloody nose.L BLEED DUCT warning message; followed by L ENG BLEED caution message; which resulted in both bleed valves closing and a lack of pressurization.Emergencies happen. In debriefing with my crew; we felt we worked well as a team; and handled the situation with a successful outcome. The passengers were shaken; but remained calm and appreciative.
