(Answered) Can you calculate the equivalent exposure for the following

Academics

Can you calculate the equivalent exposure for the following two metals using the formula and the information provided?

E_m=(C₁÷L₁+C₂÷L₂)+. . .(C_n÷L_n)

Where:

E_m is the equivalent exposure for the mixture.

C is the concentration of a particular contaminant.

L is the exposure limit for that substance specified in subpart Z of 29 CFR part 1910.

The value of E_m shall not exceed unity (1).

Metal Fume concentration result of sampling OSHA PEL ACGIH TLV

Cadmium 0.025 mg/m³ 0.1 mg/m³ 0.01 mg/m³

Chromium 0.02 mg/m³ 1 mg/m³ 0.5 mg/m³
