Movement of bromacil and hexazinone in soils of Hawaiian pineapple fields   总被引:1,自引:0,他引:1  
Zhu Y  Li QX 《Chemosphere》2002,49(6):669-674
Bromacil and hexazinone have been heavily used to control weeds in the pineapple fields in central Oahu, Hawaii, USA, since 1970s and 1980s, respectively. The last application prior to this study was at a rate of 0.6 kg active ingredient (a.i.) ha(-1) for hexazinone and 1.8 or 3.4 kg (a.i.) ha(-1) for bromacil in the six study fields during June-October 1998. Soils were collected from 0 to 1860 cm below the surface in January-May 1999 to survey the residue profiles of the two herbicides. Stratoprobe sampling showed to be an efficient and convenient method for deep soil cores. Bromacil was detected in all the soil samples above 60 cm (105-1338 ng g(-1) dry weight) and in 74% of the samples above 400 cm (26-473 ng g(-1)). Trace amounts of bromacil (90-113 ng g(-1)) were detected in some of the samples collected from as deep as 1540 cm. Hexazinone was detected in three of the six fields at 0-60 cm only (86-107 ng g(-1) dry weight). The more frequent detection of bromacil at higher concentrations than hexazinone is related to the prolonged higher application rates of bromacil in the fields and its higher persistence and mobility in soil.  相似文献

Pollution from supply chains can be controlled through the high level of efficiency realized by green supply chains. However, realizing a green supply chain depends on partners’ collaboration intentions. The purposes of this study are to explore the influence of oligopolies created through government intervention and how they can promote supply chain partners’ collaboration intentions in the context of green supply chains. Spearman’s correlation analysis, partial least squares, and the Sobel test are the main approaches adopted to evaluate the theoretical framework and hypotheses of this study. Our findings indicate that, in addition to a few leaders of the supply chain obtaining market order distribution authority, oligopolies created through government intervention guide consumers to more fully scrutinize these supply chain leaders and their partners. When their partners exhibit a lower collaboration intention in green supply chain improvement and increase the pollution emission risk, it is easy to induce and increase social pressure from consumers and thus pressure these leaders to reduce or even cancel the order distribution of these partners. To avoid order profit loss, these partners will continue to actively maintain their collaboration intentions in the green supply chain. In addition, environmental risk audits by supply chain leaders’ interventions are a common approach to improve green supply chains. However, partners are usually unwilling to cooperate with leaders’ audit interventions and show lower collaboration intentions. However, social pressure can threaten partners’ order profits and thus drive partners to show positive collaboration intentions and further accept leaders’ reasonable interventions in environmental risk audits and will have a positive effect on green supply chain improvement. Based on the above, to expedite the improvement of the green supply chain, oligopolies created through government intervention are not only an important external force but also an important national strategy in green environmental improvement.
