IDENTIFICATION AND USE: Triclopyr is a solid. It is used as an herbicide that acts via the auxin system in plants. HUMAN EXPOSURE AND TOXICITY: Triclopyr is irritating to skin and eyes. One case report describes patient who ingested triclopyr and developed metabolic acidosis and coma with cardiovascular impairment. ANIMAL STUDIES: In male mice, triclopyr (480 mg/kg/day) caused single cell necrosis of the liver, significant increases in alkaline phosphatase, aspartate transaminase, and alanine transaminase, and enlargement of the liver with dark color. Centrilobular swelling and degeneration of hepatocytes were observed in a dose-dependent fashion at 120 mg/kg/day and above in male mice, along with mild increases in liver enzymes at 240 mg/kg/day. Degeneration of the proximal tubules of the kidneys of male and female rats was observed in increased incidence at 20 mg/kg/day and above for both sexes. Absolute and relative kidney weight was significantly increased in male rats at the 50 mg/kg/day dose, while relative kidney weight was increased in male and female rats at 250 mg/kg/day. In a chronic toxicity/carcinogenicity study in mice, there were no compound-related tumors observed in male mice. Female mice had a significant increasing trend in mammary gland adenocarcinomas. In an Ames assay, the mutagenic potential of triclopyr was negative in Salmonella tester strains TA-1535, TA-1537, TA-1538, TA-98, and TA-100 in the absence and presence of metabolic activation. Rats maintained on diets supplying 0, 3, 10, or 30 mg/kg/day over three generations exhibited no consistent treatment-related effects on reproductive performance, pregnancy, parturition, or neonatal survival. ECOTOXICITY STUDIES: Experiments on zebrafish embryos demonstrated that 3,5,6-trichloro-2-pyridinol, a metabolite of triclopyr, appears to be more toxic during development compared to the parent compound.

吸收、分配和排泄
在加拿大魁北克省,常用活性成分为三的植物杀虫剂Garlon 4来防止树木接触到电力导线。本文旨在评估接触Garlon 4的工人的潜在健康风险。十名工人在工作班次开始后的22小时内收集尿液。测得的尿液中三的含量在1到13毫克之间变化。通过使用一种将三消除速率与吸收剂量相连的动力学模型,估计了吸收的日剂量。将这些估计的剂量与大鼠观察到的无可见效应平(NOEL):每公斤体重5毫克进行了比较。工人的日吸收剂量的上限估计被发现为大鼠NOEL的13.3%或更少。
In the province of Quebec (Canada), the phytocide Garlon 4, whose active ingredient is triclopyr, is often used to prevent trees from reaching electrical conductors. The object of this paper is to assess the potential health risks in workers coming into contact with Garlon 4. Ten workers collected their urine during the 22 hr following the beginning of a work shift. Measured urinary amounts of triclopyr varied between 1 and 13 mg. The absorbed daily doses were estimated from the amounts of triclopyr in urine through the use of a kinetic model that links the rates of triclopyr elimination to absorbed doses. These estimated doses were compared with the no-observed-effect level (NOEL) observed in rats: 5 mg per kg of body weight. The upper-bound estimations of the worker's daily absorbed doses were found to be 13.3% or less of the rat NOEL.

吸收、分配和排泄
两种除草剂2,4-D和三pyr醋酸酯(应用比例1.6:1酸当量)被作为一个混配组合由8名背包喷雾器操作员、一名混合/装载员和一名现场监督员一起应用。这个团队在2002年夏季在加利福尼亚北部进行了一个针叶树释放项目。生物监测(尿液,24小时)使用了2,4-D和三pyr(酸当量)作为快速排泄的暴露生物标志物。根据棉质全身防护服和生物监测,计算了2,4-D和三pyr的吸收剂量。基于防护服上除草剂的积累,平均剂量为42.6微克(酸当量)2,4-D/千克-天和8.0微克(酸当量)三pyr/千克-天。连续六天的尿液收集显示,背包喷雾器操作员平均排泄了11.0微克(酸当量)2,4-D/千克-天和18.9微克(酸当量)三pyr/千克-天。根据曲线拟合的估计值为17.1和29.3微克(酸当量)/千克-天。结果表明,对于2,4-D,被动剂量测定法持续高估了使用生物监测测量的剂量的2-3倍,而对于三pyr,基于生物监测的被动剂量测定法低估了吸收剂量2-4倍。
Two herbicides, 2,4-D and triclopyr esters (application ratio 1.6:1 acid equivalents) were applied as a tank mix by a crew of 8 backpack sprayer applicators, a mixer/loader, and a field supervisor. The crew was employed in a conifer release program in northern California during the summer of 2002. Biomonitoring (urine, 24 hr) utilized 2,4-D and triclopyr (a.e.) as rapidly excreted exposure biomarkers. The absorbed dosages of 2,4-D and triclopyr were calculated based upon cotton whole body suits and biomonitoring. Dosages based upon accumulation of the herbicides on body suits averaged 42.6 ug (a.e.) 2,4-D/kg-d and 8.0 ug (a.e.) triclopyr/kg-d. Six consecutive days of concurrent urine collections showed that backpack applicators excreted an average of 11.0 ug (a.e.) 2,4-D/kg-d and 18.9 ug (a.e.) triclopyr/kg-d. Estimates based upon curve fitting were 17.1 and 29.3 ug (a.e.)/kg-d, respectively. Results suggest that passive dosimetry for 2,4-D consistently overestimated the dosage measured using biomonitoring by a factor of 2-3 fold, while for triclopyr, passive dosimetry underestimated the absorbed dose based on biomonitoring by a factor of 2-4 fold.

吸收、分配和排泄
(14)C-三酸(含量98.8% a.i.)在低剂量口服(3 mg/kg)、重复低剂量口服(3 mg/kg x 14天)和高剂量(60 mg/kg)下的雄性和雌性大鼠体内的分布和代谢进行了研究。比较静脉给药和口服给药大鼠的分布数据表明,三酸在口服给药后吸收良好。在低剂量下,排泄相对较快,大部分放射性在24小时内通过尿液排出。在60 mg/kg剂量下,由于肾排泄机制的明显饱和,雄性和雌性大鼠在0-12小时内尿液中(14)C-三酸衍生的放射性排出量减少。粪便是(14)C-三酸衍生放射性排出的次要途径,通过呼出气体排出也是如此。重复低剂量口服给药在雄性或雌性大鼠的(14)C-三酸代谢或分布方面没有观察到显著影响。所有剂量组的残留(14)C-三酸衍生放射性均极小,但在两性的肾周脂肪和雌性大鼠的卵巢中检测到了可测量的组织放射性平,这些平似乎随剂量增加而增加。因此,这些组织中可能发生(14)C-三酸衍生放射性的潜在积累。通过HPLC和GC/MS分离和鉴定了(14)C-三酸的尿液代谢物。未代谢的母体化学物质占尿液放射性的>90%,其余由代谢物3,5,6-三-2-吡啶(3,5,6-TCP)以及可能的3,5,6-TCP葡萄糖苷酸和/或硫酸盐结合物组成。静脉给药后血浆中(14)C-三酸的消除符合一室模型,半衰期为3.6小时,在60 mg/kg剂量下,从0-12小时为零级动力学。使用SIMUSOLV建模软件优化了动力学参数。该模型显示了一个明显的“翻转”现象,在3 mg/kg剂量下,吸收限制了(14)C-三酸衍生放射性的消除,但在60 mg/kg剂量下,肾排泄饱和,因此限制了(14)C-三酸衍生放射性的消除。
Disposition and metabolism of (14)C-triclopyr acid (98.8% a.i.) was investigated in male and female rats at a low oral dose (3 mg/kg), repeated low oral doses (3 mg/kg x 14 days), and a high dose (60 mg/kg). Comparison of disposition data in intravenously dosed and orally dosed rats demonstrated that triclopyr was well absorbed after oral administration. Excretion was relatively rapid at the low dose, with a majority of radioactivity eliminated in the urine by 24 hours. At 60 mg/kg, urinary elimination of (14)C-triclopyr derived radioactivity was decreased in male and female rats from 0-12 hours, due to apparent saturation of renal elimination mechanisms. Fecal elimination of (14)C-triclopyr derived radioactivity was a minor route of excretion, as was elimination via exhaled air. No significant effect was observed on metabolism or disposition of (14)C-triclopyr from repeated low oral dosing in male or female rats. Residual (14)C-triclopyr derived radioactivity was minimal in all dose groups, but measurable levels of tissue radioactivity were detected in perirenal fat of both sexes and ovaries of female rats which apparently increased with dose. Thus, potential accumulation of (14)C-triclopyr derived radioactivity may occur in these tissues. Urinary metabolites of (14)C-triclopyr were isolated and identified by HPLC and GC/MS. Unmetabolized parent chemical represented >90% of urinary radioactivity, with the remainder accounted for by the metabolite 3,5,6-trichloro-2-pyridinol (3,5,6-TCP), and possible glucuronide and/or sulfate conjugates of 3,5,6-TCP. Plasma elimination following intravenous administration of (14)C-triclopyr was consistent with a one-compartment model with an elimination half-life of 3.6 hr and zero-order kinetics from 0-12 hours at the 60 mg/kg dose. Kinetic parameters were optimized using SIMUSOLV modeling software. The model showed an apparent "flip-flop" phenomenon, in which absorption at the 3 mg/kg dose was rate limiting in elimination of (14)C-triclopyr derived radioactivity, but renal excretion was saturated and therefore limiting in elimination of (14)C-triclopyr derived radioactivity at the 60 mg/kg dose.

吸收、分配和排泄
的血液平和尿液排泄在给予单次口服剂量0.1和0.5毫克/千克体重的六名志愿者中进行监测。这些志愿者的五种后来在相当于3.7毫克三/千克体重的 forearm上应用了Garlon 4除草剂配方。口服给药后,血药浓度在2-3小时内达到峰值,在48小时内降至检测不到的平;超过80%的剂量以未改变的三形式出现在尿液中。应用剂量的平均百分比为1.37%;在纠正口服给药后的回收情况后,这相当于1.65%的吸收率。三通过皮肤吸收缓慢,并迅速消除。它对人体内积累或通过皮肤吸收急性毒性的潜力非常低。
Blood levels and urinary excretion of triclopyr, the active ingredient in Garlon herbicides, were followed in six volunteers given single oral doses of 0.1 and 0.5 mg/kg body weight. Five of these volunteers later received dermal applications of Garlon 4 herbicide formulation equivalent to 3.7 mg triclopyr/kg body weight applied to the forearm. Following oral administration blood levels peaked at 2-3 hr and declined to undetectable levels within 48 hr; more than 80% of the dose was found as unchanged triclopyr in the urine. An average of 1.37% of the applied dose was recovered in the urine; when corrected for recovery after oral administration this was equivalent to an absorption of 1.65%. Triclopyr is slowly absorbed through skin and is rapidly eliminated. It has very low potential to accumulate in man or to be absorbed through the skin in acutely toxic amounts.
