PCB R Documentation
PCBs and herring egg thickness
Description
Thirteen sites in the Great Lakes were selected for a study to quantify PCB
concentrations in 1982 and 1996 (Hughes et al. 1998). At each site 9-13 American
herring gull (Larus smithsonianus) eggs were randomly collected and tested for PCB content.
Usage
data(PCB)
Format
A data frame with 26 observations on the following 3 variables.
nestNest number
levelPCB levels microgram/gram of dry weight
yeara numeric vector
