    摘要： A dispensing apparatus for serially dispensing flexible plastic bags from a wound package of bags which are joined along perforated severance lines, including a panel, and at least one elongate dispensing slot extending through the panel. The slot includes relatively narrow and linearly aligned outer edge portions, and a laterally extending tongue positioned between the outer edge portions. Also, an opening is located on one side of the tongue. In use, the opening is used to facilitate thread-up of the initial bag through the slot, and the two outer edge portions serve to engage and hold the bag in the slot. During withdrawal, the tongue engages the central portion of the bag, and when the tongue engages the next perforated severance line, or the bottom of the cut out in the case of T-shirt bags, a significant resistance is imparted which causes the severance line to rupture, with the next bag positioned in the slot and ready to be engaged and withdrawn.

    摘要： A bag holder device for retaining a bag in an upright and open position for allowing an individual to fill the bag with debris. The inventive device includes a first support member and a second support member that are extendible into a ground surface. The first support member includes a pair of first legs, a pair of first arm members extending from the first legs, and a first bar member extending between the first arm members. The second support member includes a pair of second legs, a pair of second arm members extending from the second legs, and a second bar member extending between the second arm members. The first bar member and the second bar member are surrounded by a first engaging member and a second engaging member respectively for engaging a paper bag. A first board having first apertures and a second board having second apertures is included for receiving the first support member and the second support member upon hard surfaces such as concrete or asphalt.

    摘要： The present invention provides a method of reducing the concentration of recalcitrant organic contamination in a soil matrix. The method includes the steps of incubating the contaminated soil matrix with unacidified ozone sufficient to reduce the concentration of the recalcitant organic contamination in the soil matrix by about 10% to about 15%; and then applying unacidified ozone to the soil matrix sufficient to substantially reduce the concentration of the recalcitrant organic contamination in the soil matrix. During the incubation phase, the ozone demand of competitive, non-contaminant ozone consumers in the soil is satisfied. Additionally, during the incubation phase, ozone conditions the contaminated soil matrix to prepare the recalcitrant organic contamination for subsequent rapid and substantial destruction. When the concentration of the recalcitrant organic contamination has been reduced by from about 10% to about 15% in the soil, the incubation phase has ended such that the application of additional unacidified ozone to the soil matrix rapidly and substantially reduces the concentration of the recalcitrant organic contamination in the soil matrix.

    摘要翻译： 本发明提供一种降低土壤基质中顽固有机污染物浓度的方法。 该方法包括以下步骤：将污染的土壤基质与不足够的臭氧一起孵育，足以将土壤基质中顽固有机污染物的浓度降低约10％至约15％; 然后将不溶的臭氧施加到土壤基质中，足以显着降低土壤基质中顽固有机污染物的浓度。 在孵化阶段，土壤中竞争性非污染臭氧消费者的臭氧需求得到满足。 此外，在孵化阶段，臭氧会对受污染的土壤基质进行处理，以制备顽固的有机污染物，以便后续的快速和实质的破坏。 当土壤中顽固性有机污染物的浓度降低约10％至约15％时，孵化阶段已经结束，使得向土壤基质中施加额外的不溶臭氧迅速且显着降低了顽固的浓度 土壤基质中的有机污染物。
