To measure the amounts of pesticide residue in wool grown in Queensland between 1997 and 1999, and to describe the use of pesticides for the control of lice infestations and blowfly strike in Queensland sheep flocks.
Pesticide residues were measured in a random sample of wool from Queensland clips offered for sale during 1998 and 1999. Information on pesticide use was obtained from a trace-back postal survey.
Samples taken from wool lots were tested for the presence and amount of organophosphorus (OP), synthetic pyrethroid (SP) and insect growth regulator pesticides. A questionnaire seeking information on flock characteristics and pesticide use was sent to the manager of each flock from which a wool sample was tested.
The mean amount of OP and SP residue was 2.0 and 0.8 mg/kg, respectively. Ninety-five and 98% of wool samples contained < 9 mg/kg and 7 mg/kg of OP and SP residues, respectively. The mean amount of cyromazine, diflubenzuron and triflumuron was 12.7, 5.8 and 13.0 mg/kg, respectively. The amounts of OP, cyromazine and triflumuron residues were greater in wool from flocks located in southern Queensland.
Most (95%; 95% CI, 92-97%) Queensland wool clips grown between 1997 and 1999 meet the suggested Australian maximum acceptable residue amounts for OP and SP pesticides.
测定1997年至1999年间在昆士兰州生长的羊毛中的农药残留量，并描述昆士兰州羊群中用于控制虱子侵扰和蝇蛆病的农药使用情况。
对1998年和1999年出售的昆士兰州羊毛剪取的随机样本进行农药残留量测定。通过追溯邮政调查获取农药使用信息。
对从羊毛批次中采集的样本进行有机磷（OP）、合成拟除虫菊酯（SP）和昆虫生长调节剂农药的存在情况和含量检测。向每个提供羊毛样本进行检测的羊群管理者发送一份关于羊群特征和农药使用情况的调查问卷。
OP和SP残留的平均含量分别为2.0和0.8毫克/千克。分别有95%和98%的羊毛样本中OP和SP残留量低于9毫克/千克和7毫克/千克。环丙氨嗪、敌百虫和氟虫脲的平均含量分别为12.7、5.8和13.0毫克/千克。位于昆士兰州南部的羊群的羊毛中OP、环丙氨嗪和氟虫脲的残留量更高。
1997年至1999年间生长的大多数（95%；95%置信区间，92 - 97%）昆士兰州羊毛剪符合澳大利亚建议的OP和SP农药最大可接受残留量。
