The brand new Department likewise has little information on breathing toxicity all over differing weights so you can mammals and especially wild birds in general
Despite the apparent need, the available research has not specifically addressed allometric equations that relate bird and mammal weight to inhalation toxicity. There is a lack of information from the open literature on inhalation toxicity of semi-volatile and volatile pesticides to birds and mammals of different sizes. The current use of allometric equations reviewed above represents the best available science that can be used in the context of inhalation toxicity. This model therefore employs the same allometric adjustment to the LDfifty to account for differences in the size of the bird or mammal in order to obtain an adjusted LD50 of a 0.020 kg bird or 0.015 kg mammal. In addition, the model accounts for differences in respiratory volume by applying the allometric equation relating body weight to inhalation rate to obtain a weight adjusted volume inhaled per unit time.
