Effect of long term aldicarb
applications on the development of field populations of some endoparasitic nematodes.
Eight of these chemicals were included in our current "high-priority" list, and the 6 remaining chemicals were very weak human AChE inhibitors, 2 of which, aldicarb
and dichlorvos, were identified as possible "false negatives" from our similarity analysis at a threshold of 75%.
The Member States trying to keep approval for aldicarb
are instead trying to win the Commission over to a compromise under which the use of the pesticide would be restricted but not outlawed completely.
Examples of pesticide active ingredients responsible for poisoning Organophosphates Methyl parathion Ethal parathion Malathion Diazinon Fenthion Dichlorvos Chlorpyrifos Trichlorfon Anticoagulants Brodifacoum Difethialone Chlorofacinone Coumachlor Difenacoum Diphacinone Warfarin Pyrethroids Allethrin Bifenthrin Cypermeter Permethrin Deltamethrin Organochlorines Lindane (lice shampoo) Carbamates Aldicarb
Carbofuran Oxamyl Methomyl Formetanate Methiocarb Aminocarb Mecarbam Bendiocarb Propoxur Herbicides Glysophate Atrazine Nicosulfuran Fenoxaprop Alachlor Pendimethalin Halosulfuran-methyl Paraquat Triclopyr Clopyralid Picloram N,N-diethyl-meta-toluamide (DEET- mosquito repellent)
Ever use of phosmet and of tebupirimfos were significantly associated with ankle reflex abnormality, whereas ever use of aldicarb
was inversely associated with ankle reflex abnormality.
Two treatments were compared: unprotected crops and crops protected with aldicarb
applied in the soil at sowing (0.45 kg [ha.sup.-1]).
Increased rate ratios (or odds ratios) and positive exposure--response patterns were reported for 12 pesticides currently registered in Canada and/or the United States (alachlor, aldicarb
, carbaryl, chlorpyrifos, diazinon, dicamba, S-ethyl-N,N-dipropylthiocarbamate, imazethapyr, metolachlor, pendimethalin, permethrin, trifluralin).
At planting, aldicarb
15G [2-methyl-2-(methylthio) propionaldehyde O-(methylcarbomoyl)oximel was applied at a rate of 0.94 kg a.i.
(1999) measured aggressive behavior, thyroxine hormone levels, and ability to make antibodies against a foreign protein in mice treated with atrazine, aldicarb
, and nitrate (and their mixtures) at maximum concentrations typically detected in groundwater.
The chemicals were dissolved in ethanol (except for aldicarb
, atrazine, and simazine, which were dissolved in DMSO) at the original concentration of [10.sup.-2] mol/L.
must be aware of the tragic misapplication of the carbamate insecticide aldicarb
to watermelons in California in 1986, resulting in 6 deaths, 17 hospitalizations, and > 1,000 probable or possible poisoning cases (Centers for Disease Control and Prevention 1986).
The safety reviews still to be completed are those for carbamate pesticides as a class and the carbamate aldicarb
