Answer #1

a)PEL is expanded as Permissible Exposure Limit : The defenition of OSHA for PEL is:

It is the Time-weighted average (TWA) concentrations that should not be exceeded during any 8-hour work shift of a 40-hour workweek.

Chlorine's current limit is 0.5 ppm (earlier this was 1 ppm), with a 15-minute short-term exposure limit of 1 ppm.

b)Hazard is f WTP- There is potential danger of leakage of harmful gases like chlorine in Waste water treatment plants.

Hazard of WWTP - Waste Water treatment plants are major sources of aerosols that are harmful for inhabitants living around it.

Halogenated compounds are particularly easy to identify by their mass spectra because chlorine and bromine occur naturally as mixtures of two abundant isotopes. Chlorine occurs as 35Cl (75.8%) and 37Cl (24.2%); Bromine occurs as 79Br (50.7%) and 81Br (49.3%); Boron compounds also stand out owing to the two isotopes 10B (19.9%) and 11B (80.1%). For the compound Bromoethane, C2H5Br: At what masses do the molecular ions occur? ___________________ (List in order of increasing mass separated by commas, e.g. 120,122.) What...
