Chemicals such as polycyclic aromatic hydrocarbons (PAHs), phthalateesters, parabens, siloxanes and squalene, all of them classified as endocrine-disrupting chemicals (EDCs), have been reported to occur in all environmental compartments. The effects of EDCs on development, reproduction, growth, metabolism and obesity constitute a real public health issue. A list of EDCs (> 40 compounds) were characterised in total suspended particulates (outdoor soot: 92 samples) collected in July-September 2016 in an Algiers urban area; besides, settled indoor dusts (36 samples) were collected between November and December 2016 in schools, homes, manufacture and hospital of the same province. The analytical procedure consisted of ultrasonic bath extraction, column chromatography separation into fractions of different polarity and gas chromatographic-mass spectrometric processing. The total loads of phthalates ranging from 6.0 to 347 ng/m (median, 26 ng/m) were determined in indoor dust and 4.6 to 11.6 ng/m (median, 7.9 ng/m) in outdoor soot; meanwhile, PAHs ranged from 12.1 to 108 ng/m (median, 36 ng/m) in indoor dust and ranged from 5.6 to 7.7 ng/m (median 5.7 ng/m) in outdoor soot. Finally, illicit substances such as cocaine, cannabinol and Δ-tetrahydrocannabinol were found to range from 0.5 to 11 pg/m, 4.6 to 9.2 pg/m and 11 to 81 pg/m, respectively, in outdoor soot.
多环芳烃（PAHs）、邻苯二甲酸酯、对羟基苯甲酸酯、硅氧烷和角鲨烯等化学物质均被归类为内分泌干扰物（EDCs），据报道它们存在于所有环境介质中。EDCs 对发育、生殖、生长、代谢和肥胖的影响构成了一个真正的公共卫生问题。2016 年 7 月至 9 月，在阿尔及尔市区采集了 92 个室外烟尘样本和 36 个室内尘埃样本，共鉴定出超过 40 种 EDCs。此外，2016 年 11 月至 12 月，在同一省份的学校、家庭、工厂和医院收集了室内尘埃样本。分析过程包括超声浴提取、柱层析分离不同极性的馏分和气相色谱-质谱处理。室内尘埃中的邻苯二甲酸盐总负荷为 6.0 至 347ng/m（中位数为 26ng/m），室外烟尘中的邻苯二甲酸盐总负荷为 4.6 至 11.6ng/m（中位数为 7.9ng/m）；同时，室内尘埃中的多环芳烃含量为 12.1 至 108ng/m（中位数为 36ng/m），室外烟尘中的多环芳烃含量为 5.6 至 7.7ng/m（中位数为 5.7ng/m）。最后，在室外烟尘中发现了可卡因、大麻酚和 Δ-四氢大麻酚等非法物质，其浓度范围分别为 0.5 至 11pg/m、4.6 至 9.2pg/m 和 11 至 81pg/m。
