Emerging pollutants represent a group of synthetic or naturally occurring compounds that are not normally monitored within the environment but can enter into the environment and cause different adverse ecological and health effects. This systematic review identified the various emerging pollutants in Nigeria. The following databases, ScienceDirect, PubMed, Google Scholar, and African Journals OnLine (AJOL) were searched to identify studies on pollutants of emerging concerns in Nigeria. A total of 933 articles were identified out of which 30 articles were selected to be eligible for the study. Over 250 emerging pollutants were identified and divided into 9 major groups which are personal care products, pharmaceuticals, industrial chemicals, polycyclic aromatic hydrocarbons, volatile organic compounds, pesticides, mycotoxins, radionuclides and electromagnetic radiations (Gamma radiation) and other pollutants of emerging concerns such as microbes, microplastics, and particulate matter. These pollutants are found in water bodies and underground waters, soils and sediments, biological systems, and ambient air at different concentrations with seasonal variations. Some of these pollutants act as endocrine disruptors, β-adrenergic receptors agonist blockers, oxidative stress inducers and can cause genetic alterations in DNA and epigenetic reprogramming through global DNA methylation, gene-specific CpG methylation and microRNA expression. Emerging pollutants of public health concern in Nigeria are on the increase and are threat to both ecological and human health.

尼日利亚的新兴污染物:系统评价

新兴污染物代表一组合成或天然存在的化合物,它们通常不会在环境中进行监测,但可以进入环境并造成不同的不利生态和健康影响。该系统评价确定了尼日利亚的各种新兴污染物。搜索了以下数据库、ScienceDirect、PubMed、Google Scholar 和非洲期刊在线 (AJOL),以确定对尼日利亚新出现的污染物的研究。共确定了 933 篇文章,其中 30 篇被选为符合研究条件。确定了250多种新兴污染物,分为个人护理用品、药品、工业化学品、多环芳烃、挥发性有机化合物、农药、霉菌毒素、放射性核素和电磁辐射(伽马辐射)以及其他新出现的污染物,如微生物、微塑料和颗粒物。这些污染物存在于水体和地下水、土壤和沉积物、生物系统和环境空气中,浓度不同,季节性变化。这些污染物中的一些充当内分泌干扰物、β-肾上腺素能受体激动剂阻滞剂、氧化应激诱导剂,并可通过全局 DNA 甲基化、基因特异性 CpG 甲基化和 microRNA 表达导致 DNA 的遗传改变和表观遗传重编程。尼日利亚引起公共卫生关注的新兴污染物正在增加,并对生态和人类健康构成威胁。和颗粒物。这些污染物存在于水体和地下水、土壤和沉积物、生物系统和环境空气中,浓度不同,季节性变化。这些污染物中的一些充当内分泌干扰物、β-肾上腺素能受体激动剂阻滞剂、氧化应激诱导剂,并可通过全局 DNA 甲基化、基因特异性 CpG 甲基化和 microRNA 表达导致 DNA 的遗传改变和表观遗传重编程。尼日利亚引起公共卫生关注的新兴污染物正在增加,并对生态和人类健康构成威胁。和颗粒物。这些污染物存在于水体和地下水、土壤和沉积物、生物系统和环境空气中,浓度不同,具有季节性变化。这些污染物中的一些充当内分泌干扰物、β-肾上腺素能受体激动剂阻滞剂、氧化应激诱导剂,并可通过全局 DNA 甲基化、基因特异性 CpG 甲基化和 microRNA 表达导致 DNA 的遗传改变和表观遗传重编程。尼日利亚引起公共卫生关注的新兴污染物正在增加,并对生态和人类健康构成威胁。这些污染物中的一些充当内分泌干扰物、β-肾上腺素能受体激动剂阻滞剂、氧化应激诱导剂,并可通过全局 DNA 甲基化、基因特异性 CpG 甲基化和 microRNA 表达导致 DNA 的遗传改变和表观遗传重编程。尼日利亚引起公共卫生关注的新兴污染物正在增加,并对生态和人类健康构成威胁。这些污染物中的一些充当内分泌干扰物、β-肾上腺素能受体激动剂阻滞剂、氧化应激诱导剂,并可通过全局 DNA 甲基化、基因特异性 CpG 甲基化和 microRNA 表达导致 DNA 的遗传改变和表观遗传重编程。尼日利亚引起公共卫生关注的新兴污染物正在增加,并对生态和人类健康构成威胁。
