WebChlorophyll . a. is often reported in mass per unit volume, e.g. ug/L, mg/L. The chlorophyll . a. threshold for impacts on fish is generally considered to be 100 ug/L. 4. The cleanest waters will have chlorophyll-a. levels of less than 5 ug/L. 5. The specific, applicable water quality standard will depend on the uses and goals for that water body. WebMay 2, 2013 · Three variables, chlorophyll a, Secchi depth, and total phosphorus, independently estimate algal biomass. Phosphorus, Chlorophyll-a (algae concentration) and Secchi depth are related. When phosphorus increases, that means there is more food available for algae, so algal concentrations increase.

WebYou can measure chlorophyll a content as ug/g and then convert the resulting value to mg/m2 as: 2 chl. a = (0.001 × ug chl. a) × weight of 1 m2 leaf (g) Kazem Ghassemi-Golezani VOTE Reply David Paul a year ago Follow On the same note, I want to convert ug/L to ug/m2. Is this feasible? I know 1 litre = 0.01 m2. WebTSI = 9.81 ln Chlorophyll a (ug/L) + 30.6 TSI = 14.42 ln Total phosphorus (ug/L) + 4.15 where: TSI = Carlson trophic state index ln = natural logarithm The formulas for calculating the Carlson Trophic State Index values for Secchi disk, chlorophyll a, and total phosphorus are presented below. mydmv.colorado.gov vehicle services
