Scope

Concentrations of PCDD/Fs in fish describes average concentrations of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans furans (PCDD/Fs) in fish. Concentrations of sea and freshwater fish species are studied separately.

Definition

Data

POP concentrations in Baltic sea fish have been measured from samples collected in EU-kalat project.

Causality

Unit

pg/g fw

Formula

library(OpasnetUtils)
library(ggplot2)

dat <- opbase.data("Op_en3104", subset = "POPs")
dat <- dat[dat$POP == "2378TCDD" , ]

oprint(aggregate(dat$Fish_species, dat[c("Fish_species", "N_individuals", "Matrix")], FUN = length))

dat <- dat[dat$Fish_species == "Baltic herring" , ]
ggplot(dat, aes(x = Result, colour = N_individuals))+geom_density()+scale_x_log10()
