城市乱扔垃圾被认为是全球重要的环境和公共问题。这个问题在南美洲南部地区的沿海社区中日益严重。本研究的目标是评估（1）城市垃圾的丰度和组成； (2) 其丰度的时空变化； (3) 阿根廷人口最多的沿海城市马德普拉塔的垃圾数量与三个人为变量（即行人数量、停放车辆数量和垃圾桶数量）之间的关系。 2008 年 4 月至 2009 年 3 月，在四个地点对 88 个横断面进行了采样，每个横断面面积为 1425 m(2)。结果显示，有 20,336 件物品（每 m(2) 约 14 件），其中烟头（33%）、纸张（31%）和塑料（22%）是最常乱扔的物品。工业区（城市港口）的垃圾数量较多，而全年垃圾数量相对均匀。冗余分析技术表明，与城市中央商务区和靠近主要海滨度假胜地的区域相关的所有三个人为变量都非常丰富，那里的烟头和纸张占主导地位。这是第一项研究阿根廷高密度沿海城市城市垃圾的空间和时间变化的研究。我们的研究结果表明，解决与城市垃圾相关的问题必须包括针对行人和停放车辆车主的密集教育和广告活动，但还应考虑减少废物、清理行动和执法。 (C) 2011 Elsevier Ltd. 保留所有权利。
Urban littering is considered an important environmental and public issue globally. This problem is growing considerably within coastal communities of the southern region of South America. The goals of this study were to assess (1) the abundance and composition of urban litter; (2) the spatial and temporal variations of its abundance; and (3) the relationship between the abundance of litter and three anthropogenic variables (i.e. abundance of pedestrians, of parked vehicles, and of trash bins) in Mar del Plata, the most populated coastal city in Argentina. Eighty-eight transects, each covering 1425 m(2), were sampled along four sites from April 2008 to March 2009. Results showed 20,336 items (ca. 14 items per m(2)) of which cigarette butts (33%), papers (31%), and plastics (22%) were the most commonly littered items. Higher amounts of litter were found in an industrial area (city's harbor), while the abundance of litter appeared relatively even throughout the year. Redundancy analysis techniques indicated a high abundance of all three anthropogenic variables associated with the central business district area of the city and an area in close proximity to a major seaside resort, where cigarette butts and papers dominated. This is the first study that has examined spatial and temporal variations of urban litter in a high-density coastal city in Argentina. Our results showed that addressing the problems associated with urban litter must include intensive educational and advertising campaigns directed at pedestrians and owners of parked vehicles, but waste reduction, clean-up operations and law enforcement should be also considered.
