从2008年到2009年，我们评估了一个水泥厂（Montcada i Reixac，加泰罗尼亚，西班牙）的环境影响，该水泥厂位于人口稠密地区附近。还评估了居住在附近的人口的潜在健康风险。从设施的不同方向和距离收集的土壤、植被和空气样本中确定了各种重金属的水平和多氯二苯并对二恶英和多氯二苯并呋喃的浓度。进行了三次6个月的连续运动，以确定时间和季节趋势。使用了多变量统计技术，如主成分分析。还计算了人类接触金属和多氯二苯并对二恶英/多氯二苯并呋喃的情况，以及相关的致癌和非致癌风险。环境污染物浓度，特别是在城市地区发现的浓度，略高于最近报告的加泰罗尼亚其他水泥厂周围的浓度。观察到一个季节性模式，在较冷的采样期间记录的值较高。尽管如此，人类接触金属和多氯二苯并对二恶英/多氯二苯并呋喃的致癌和非致癌风险仍在国际监管机构认为可接受的范围内。
From 2008 to 2009, we evaluated the environmental impact of a cement plant (Montcada i Reixac, Catalonia, Spain) that is located close to densely populated areas. The potential health risks for the population living in the neighborhood were also assessed. The levels of various heavy metals and the concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were determined in soil, vegetation, and air samples collected at different directions and distances from the facility. Three 6-monthly consecutive campaigns were performed to establish temporal and seasonal trends. Multivariate statistical techniques, such as principal component analysis, were used. Human exposure to metals and PCDD/Fs, as well as the associated carcinogenic and noncarcinogenic risks, were also calculated. Environmental pollutant concentrations, especially those found in urban sites, were noted to be slightly higher than those recently reported around other cement plants in Catalonia. A seasonal pattern was observed, with higher values recorded during the colder sampling periods. Despite this, the carcinogenic and noncarcinogenic risks derived from human exposure to metals and PCDD/Fs were within the ranges considered acceptable by international regulatory organisms.
