WebJan 23, 2024 · However, determination coefficients R2 remained in the range of 0.36–0.51, highlighting the necessity of bioaccumulation analysis to fully estimate environmental risk. The results show that DDT contamination, even if residual, may still represent a risk due to its effective transfer to the trophic chain. WebThe field GC portion of total organics is determined by field analysis of a bag sample by GC with a flame ionization detector (FID). This procedure is described in this document as Appendix A and in EPA Draft Method 0040 (Appendix E). The identified range of organics for field GC is defined by boiling point range, in this case < 100 E C.
