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 LD50 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. By adjusting both the LD50 and the inhalation rate to a 0.020 kg bird and a 0.015 kg mammal, this tool provides a conservative comparison of exposure to toxicity based on the current state of knowledge.
A new assumption 's the element of bird otherwise mammal to help you inhale dirt away from 100 m during the diameter or a reduced amount of the latest direct squirt droplet shipping once applying of this new pesticide. Previous discussions during the 2004 Drain (Us EPA, 2004a) provided notion towards the measurements of particles you to a bird try capable breathe and you may respire.
