摘要

尼日利亚拉各斯这座超大型城市受到各种环境问题的困扰，其中最主要的问题是城市工业废物管理不善和脱节造成的环境污染。本研究旨在确定和量化拉各斯州产生的城市工业废物类型。该州拥有尼日利亚最大的人口基数，人口超过 2000 万。研究采用了准实验设计。借助热质量气体流量计测定了土壤、工业废物产生量和污染物水平。使用称重秤对工业废物进行了现场测量，同时收集了 0-30 厘米深的表层土壤样本。结果表明，大都市产生的工业废物中有 20% 是可燃的（可能自燃）。随后，将这些结果与拉各斯州空气和土壤中各种污染物的允许限值国际标准进行了比较。在拉各斯产生的工业废物中，伊科罗杜的比例最大，其次是伊科贾、奥肖迪、奥霍/阿拉巴和苏卢雷。这些结果和发现的意义在于，为了有效监测和实施管理战略，拉各斯州需要在适当立法、执法和跟踪工业废物产生方面做大量工作。

SPATIAL ASSESSMENT OF POLLUTANTS CONCENTRATION IN AIR AND SOILS IMPACTED BY INDUSTRIAL WASTES IN LAGOS STATE, NIGERIA.

The mega city of Lagos, Nigeria is plagued by various environmental issues, chief amongst them being environmental pollution induced by poor and disjointed urban industrial waste management practices. This study aimed to identify and quantify the types of urban industrial waste generated in Lagos State. The State plays host to the largest population base in Nigeria with over 20m people. The study adopted a quasi-experimental design. Soil, industrial waste generation and pollutant levels were determined with the aid of a thermal mass gas flow meter. Industrial wastes were measured in-situ using a weighting scale, while surface soil samples were collected at depths of 0-30cm. Results show that 20% of the industrial waste generated in the metropolis was ignitable (possibility of spontaneous combustion). The results were thereafter compared with international standards on the permissible limits for various pollutants in air and soil of Lagos State. Ikorodu had the greatest contribution of industrial waste generated in Lagos, followed by Ikeja, Oshodi, Ojo/Alaba and Surulere. The implications of these results and findings is that a lot needs to be done in terms of appropriate legislation, enforcement and tracking of industrial waste generation in Lagos State for effective monitoring and implementation of management strategies.

期刊介绍： ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
