Is empenthrin much safer than 1-4 dicholorobenzene? (used in mothballs)

[QUOTE="jim mcnamara, post: 6388199, member: 35824"] If this was simple I could give you a simple answer. Simple but not completely correct: Regular moth balls are a lot worse We have these kinds of questions frequently. Some people are horrified by this statement: There is a tolerance limit in county where I live -- for positive Arsenic tests in well water sources. 50ppb as I recall. So. Your definition of "safe" creates a yes/no answer to 'is it safe or toxic?' LD50 helps to answer it for you. If the medical problems from the stuff are not enough to conclude anything LD50 means if you feed test animals X grams or milligrams per kilogram of weight means that 50% will die Example for moth balls. LD=lethal dose. So assume rats and people are the same, [COLOR=rgb(184, 49, 47)]Oral LD50 =500mg/kg[/COLOR] means one half of a gram fed to each 1000g member of a rat population of 200 rats == 100 rats will die. Say the average human weighs 80kg. He/She would need to eat 40g (like 1/4 cup) to have a 50% chance of dying. So answer your own question: look at the LD50 values for ORAL for both. Then YOU decide. Not me. [/QUOTE]
