nh4Criteria(pH, Cel, toxicity = c("chronic", "acute"), salmonids = FALSE)

Arguments

pH

a water pH for the criteria

Cel

a water temperature in degrees Celsius

toxicity

the type of criteria, toxicity = 'acute' gives the acute criteria (CMC) while toxicity = 'chronic' gives the chronic criteria (CCC)

salmonids
