Description

This function calculates the Oregon DEQ pH and temperature dependent ammonia criteria. Tables of values and formulas can be found at http://www.deq.state.or.us/wq/standards/docs/tables303140.pdf.

Usage

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

logical, whether the criteria should be for streams with salmonid beneficial use (Table 30A). The default is FALSE. Ignored when toxicity = 'chronic'.

Details

Table 30A acute, salmonids are a designated use. Table 30b acute, salmonids are not a designated use. Table 30c chronic, fish and aquatic life are a designated use.

Value

a numeric vector of water quality criteria
