PVC is an organochlorine and is 'perfectly safe' unless you start burning it. Which organochlorines in which tins are you suggesting ain't perfectly safe? I'll get my chair ... My tame biochemist is unable to think of any organochlorines that are safe for mammals in large quantities. Er- we seem to have an instance of moving goalposts. Safe 'if you follow the instructions on the tin' was the original target, not 'safe for mammals in large quantities'. Do you know the meaning of the word 'bioaccumulative'? Yes. Munch on this ragwort. Why is it significant that organochlorines such as aldrin and dieldrin have 'half-lives' measured in years? With respect to this argument, the half-lives of those compounds are of no significance whatsoever.. It is possible that you misunderstood the concept of "half-life" in this context. I (possibly wrongly) understand it to mean that if I ate a 1gm of a substance now, the half-life of that substance in me is the time after which there will still be 1/2 gm of it left in me. [Franz Heymann] My suggestion was that (garden) pesticides are perfectly safe if instructions are followed. My suggestion was _not_ that previous generations of pesticides were safe, so don't bother me with aldrin and dieldrin, or I'll tell you about lead arsenate. Clearly in the light of the toxicity of water itself my 'perfectly' is an exaggeration, and I'll withdraw it if you like. There are some serious health issues on the subject of pesticides- the use of organophosphates by sheep farmers for instance- but these hardly apply on a garden scale. To return to the point, the kneejerk classification of synthetic pesticides as 'poisons' is merely hysterical when there are so many natural poisons in the garden, and so many other 'poisons' in all other aspects of modern life. -- Anton |

Dear Mr Otter, Please tell me where you have seen a tin of DDT or aldrin or dieldrin recently, so that I can check the instructions on the tin. If like me you can't find any, please let sw know which decade we're in. Ah, sarcasm. Traditional refuge of the ill-informed. Tins of these these (and more besides) are still readily available in parts of Africa and elsewhere; and the instructions on the tin are? May I humbly suggest that you have had your mileage on this one by now? [Franz Heymann] the substances themselves are persistent in the environments of countries in which they were banned. Yes. Returning to the point, compare and contrast the dangers to the user of current pesticides when properly used with: a) previously used pesticides, such as lead arsenate b) other household chemicals c) urine -- Anton |

If the term does in fact involve the time for halving the quantity in your body, then you ahould think again.

Tins of these these (and more besides) are still readily available in parts of Africa and elsewhere; and the instructions on the tin are? I don't know. The label is printed in English and I'm an illiterate African farmworker. Alternatively, I'm English, literate, and firmly believer that if some is good, more is better. You are welcome to believe that (current) (garden) pesticides are safe if used according to the instructions on the tin. It may even be true for some, although the rate at which pesticides are banned as we discover more about their effects undermines your assumption of safety. But it's even more important to recognise that many people don't read the instructions, or don't follow them. Welcome to the real world. the substances themselves are persistent in the environments of countries in which they were banned. Yes. Returning to the point, compare and contrast the dangers to the user of current pesticides when properly used with: a) previously used pesticides, such as lead arsenate b) other household chemicals c) urine You forgot to put 'current' in parentheses. I suspect there's a proper debating term for deciding to change the rules because you can't win the game. regards sarah -- Think of it as evolution in action. |

It is fundamental to the safe use of chemicals of all sorts around the house that they *never* be mixed or stored, even for a few minutes, in any container that would ever contain food or drink. I would go so far as to say that this even applies to the stuff you wash the kitchen floor with. Don't depend on anyone remembering that the Coke bottle or the peanut butter jar has paraquat in it. Urglers! Don't let your household be the site of a tragedy! In *this* household, there is a special orange bucket for mixing herbicides and an orange watering can for applying the stuff, a further refinement that ensures that herbicide residues don't get into fertilizer solutions. -- Rodger Whitlock Victoria, British Columbia, Canada |

Something that would definitely be avoided by adding bitterex. It is insane to store toxic garden chemicals in lemonade bottles, but people do and it is impossible to legislate against stupidity.

People understood the need to ban that because of its known dangers to smokers, but some still risk using it. News to me. I thought so far the limit of state intervention on nicotine was to prevent the explicit advertising of the tobacco products to addicts. Using nicotine extracts as a pesticide was always ill advised because the LD50 for humans is about the amount you can solvent extract from just one cigarette. Lucky really that smoking the stuff is so inefficient. Major problem with it is you get tobacco mosaic virus as a freeloader. There are endless versions of fake Organic(TM) "kitchen sink" chemistry recipes on the net using fag ends that are quite literally lethal if executed correctly. Fortunately, most of them use the wrong solvent for extraction. Regards, -- Martin Brown |

It is easy to check that I have rinsed off enough that even somebody licking the bowl would come to no harm. [ Clue: a microgram a day is good for you, an occasional milligram is completely harmless, and a gram is potentially lethal. ] Most fertilisers are pretty safe, too. Regards, Nick Maclaren. |
