I can't get the maximum permissible limit, as per WHO Guidelines...
Can anyone tell me and share a link of reference........will be very beneficial for me
The action level put by USFDA is 76 ppm for crustaceans and 86 ppm for molluscan bivalves. Codex has not set any MRL for As in Fish and Fishery products. There are countrywise variation in the limits.
Refer this doc.
Food Standards Code 2987 (1987), Australian Government Publishing Service, Canberra.
Australian standards-maximum residue limits for inorganic As in seafood: 2 mg/kg (for crustaceans such as crab, lobster, prawns), 1mg/kg for Molluscs (such as abalone), 2 mg/kg fish (such as sword fish, tuna, whiting)

Hi Sudeshna,
There is no current PTWI (provisional tolerable weekly intake) from the WHO. It is under review. The Committee concluded that the current PTWI for inorganic As (2.1 μg/kg bw per day) was no longer health protective and in 2011 the PTWI was withdrawn.

A nice explanation is found here as well of why this was withdrawn:
