Autocorrelated models are shown to be more reasonable from a biological perspective. Some of the most recent autocorrelated models also rely on a coherent treatment of instantaneous and average substitution rates while previous mode

Nonetheless, in certain central and eastern areas, mean or maximum recorded DDT concentrations nearing or exceeding 100 μg/kg were taped. Regarding land for building, grounds with exorbitant concentrations of HCH and DDT were primarily observed at websites of functional or defunct pesticide industrial facilities. In accordance with isomer and metabolite compositions, HCH and DDT at most sites originated from historical residues, but others was new inputs after 1983. Since 2015, the levels of HCH a
