The need to generate objective evidence and reliable information for decision makers to improve environmental policies for a better air quality, led us to evaluate the atmospheric aerosol components in the urban area of Carabayllo, by monitoring PM and PM to determine mass concentration and analyzing PM using -INAA and ICP-MS for metals quantification, ion chromatography for anions and the NIOSH method to determine organic and elemental carbon. The results obtained from mass concentration of PM and PM exceeded the permissible breathing annual average of WHO guidelines of 15 µgm and 45 µgm, respectively, which evidence an unhealthy air quality. Likewise, using the model Positive Matrix Factorization five sources of pollutants were defined: metallurgical industry, sea salt, industrial activity, dust and non-exhaust emissions and vehicle emissions.
为了生成客观证据和可靠信息，以供决策者改进环境政策以实现更好的空气质量，我们通过监测细颗粒物（PM）和可吸入颗粒物（PM）来评估卡拉瓦约市区的大气气溶胶成分，以确定质量浓度，并使用仪器中子活化分析（-INAA）和电感耦合等离子体质谱法（ICP-MS）分析细颗粒物以进行金属定量，使用离子色谱法分析阴离子，并使用美国国家职业安全与健康研究所（NIOSH）方法测定有机碳和元素碳。细颗粒物和可吸入颗粒物质量浓度的结果分别超过了世界卫生组织指南规定的年平均可吸入值15微克/立方米和45微克/立方米，这证明空气质量不健康。同样，使用正定矩阵因子分解模型确定了五种污染物来源：冶金工业、海盐、工业活动、灰尘和非尾气排放以及车辆排放。
