Considering the merits of in vivo studies in biotransformation i. e. activation or inactivation, protein-binding such as sex hormone binding protein , toxicokinetics, and more evaluative in hazard identification and risk assessment, we selected a battery of short-term and long-term in vivo studies, including uterotrophic assay in weaning mice and ovariectomized adult mice, an in vivo multiple endpoints assay, and a gestational and lactational exposure assay to identify the estrogenic effects of endosulfan on the offspring.

考虑到体内试验在代谢转化、血浆蛋白如性激素结合蛋白的结合、代谢动力学等方面比体外试验优越，在危害鉴定和危险度评定中更有价值，我们选择了多项体内试验，包括对幼年小鼠和卵巢切除成年小鼠的子宫增殖作用、对成年去势小鼠的体内多终点观察以及大鼠孕期和哺乳期接触对雄性子代生殖系统结构和功能的改变，即去雄性化或雌性化作用等，来验证硫丹的体内雌激素样作用。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
