The application of mineral and organic phosphorus fertilizers to arable land has greatly increased crop yield to meet the world food demand. On the other hand, impurities in these fertilizers, such as heavy metals, are being added to agricultural soils, resulting both from the raw materials themselves and the processes used to obtain the final product. Cadmium, a non-essential and toxic heavy metal, has been found in relatively high amounts in common P fertilizers obtained from sediments. This metal poses a high risk for soil fertility, crop cultivation, and plants in general. Furthermore, human health might be compromised by the cadmium concentrations in agricultural and livestock products, due to the bioaccumulation effect in the food web. The accumulation in the different matrixes is the result of the high mobility and flexible availability of this harmful metal. This review summarizes risks to human health, the factors influencing cadmium movement in soils and crop uptake, as well as common plant responses to its toxicity. In addition, it summarizes cadmium balances in soils, trends, long-term experiments, and further studies. Cadmium inputs and outputs in arable soil, together with their calculated concentrations, are compared between two different regions: the European countries (in particular Germany) and China. The comparison appears useful because of the different proportions in the inputs and outputs of cadmium, and the diverse geographical, environmental and social factors. Moreover, these variables and their influences on cadmium contamination improve the understanding of the pollution from phosphate fertilizers and will help to establish future mitigation policies.

污染物在流域水土环境中存在复杂的源汇关系,在水土环境中的转化作用主要受控于各种水‒ 土界面过程,为此,水土环境污染治理需将水土环境作为一个整体,通过跨介质归因识别找到真正的污染源,然后进行跨介质治理。本文首先分析了污染物在流域水土环境中的跨水‒ 土介质迁移过程以及主要影响因素,在此基础上提出了流域水土环境跨介质调控原理及关键过程,主要包括流域水土环境污染跨介质归因识别和流域水土环境污染跨介质治理。同时,重点阐述了污染物在河道外的土壤‒ 水界面、坡面‒ 河道界面,河道内的水‒ 沉积物界面(包括河床潜流带和侧向岸边潜流带的水‒固界面)和水‒ 悬浮颗粒物界面过程在跨介质去除中的重要作用,并采用实际案例阐述了流域非点源污染物的跨介质控制、河流含氮化合物的跨介质去除以及湖泊氮磷的跨介质去除方法等。研究结果可为流域水土环境污染防治提供科学依据。

通过多因素对比预实验,将筛选出的7个石油烃降解的主要影响因素以正交表方法组合起来,对其进行了实验研究。探讨了石油迁移转化对于各种土壤物理化学条件及其他环境因素改变的敏感程度,并找出了各主要影响因素的重要性和最佳水平;测定了土壤中所存在的石油污染物在生物降解作用下的后期产物,研究了不同条件下的样品残留污染物组分之间的差异。影响土壤中石油烃类降解的主要因素有土壤石油污染强度、营养物(NH4NO3、K2HPO4)、氧化剂(3%H2O2溶液)、表面活性剂(TW80)、温度、土壤含水率和土壤透气性;在降解的不同阶段,各个因素的重要性以及最佳水平会发生相应的变化;在生物降解后期,土壤中残留的石油污染物主要是正构和异构烷烃;正构烷烃的色谱图由原来的对称钟形变为左陡右缓的偏钟形;异构烷烃所占比重增大,正十五烷和正二十一烷之间的谱图基线被明显抬高。

长江三角洲地区(简称长三角地区)是我国重要的工农业生产基地,关注该地区农用地土壤重金属污染状况对促进地区经济社会良性发展、保障生态环境安全具有重要意义。本文根据近 20 年发表的长三角地区农用地土壤重金属相关文献中的重金属含量数据,全面分析长三角不同区域农用地土壤典型重金属累积情况与污染状况,系统探究导致长三角地区农用地土壤重金属累积与污染的主要原因。分析发现,工业“三废”排放、交通运输、化肥、农药、农膜等的大量施用(使用),使得长三角地区农用地土壤中重金属 Cd 累积与污染情况最为严重,其次是 Cu、 Hg 和 Pb,而浙江台州和安徽铜陵分别存在Cd、 Hg 和 Cu, Cd、 Pb 和 Cu 多种重金属复合污染问题。针对长三角地区农用地土壤重金属污染防治的迫切需求和主要污染成因,在农用地土壤重金属污染源头控制、农用地土壤重金属快速动态监测、农用地土壤分级管理、重金属污染农用地土壤修复新技术研发、农用地土壤污染防治立法等方面提出了相关防治建议,以期为改善长三角地区农用地土壤生态环境、促进优质高效农业的可持续发展提供参考。

近几十年来,我国在快速发展和工业化的同时,在环境污染防治方面也做出了巨大努力。然而,这些全国性措施(如能源结构调整)对土壤中污染物浓度的影响尚未得到很好的量化。多环芳烃(PAHs)污染在全球范围内引发重要关注,且PAHs排放与能源结构有关。因此,我们推测我国能源结构的调整可能会降低土壤中PAHs的含量。为了验证这一假设,我们于2008 年和2019 年在北京54 个点位重复采集了土壤样品,分析了美国环境保护署(US EPA)提出的16 种优控PAHs 化合物(Σ16PAHs)的浓度,并收集了过去20 年全国1704 个土壤采样点的数据。结果表明,我国Σ16PAHs浓度沿城市-郊区-农村-背景点梯度下降,且Σ16PAHs 浓度与区域总产值(GRP)有关,在GRP 较低时Σ16PAHs 浓度随GRP 的增加而增加,随后在GRP 达到一定水平时趋于平稳。过去20 年,我国土壤Σ16PAHs 的平均浓度呈下降趋势,其中北京土壤Σ16PAHs的平均浓度从2008 年的22.7 μg⋅g‒1总有机碳(TOC)显著下降到2019 年的10.0 μg⋅g‒1 TOC。源识别分析推断,土壤PAHs浓度的下降趋势是由于我国煤炭、焦炭、部分油类消费量下降以及电力、天然气等清洁能源消费量上升所致。本研究例证了调整能源结构在降低土壤多环芳烃浓度和改善土壤环境质量中的重要作用。

Environmental pollution is one of the main causes of human cancer. Exposures to environmental carcinogens result in genetic and epigenetic alterations which induce cell transformation. Epigenetic changes caused by environmental pollution play important roles in the development and progression of environmental pollution-related cancers. Studies on DNA methylation are among the earliest and most conducted epigenetic research linked to cancer. In this review, the roles of DNA methylation in carcinogenesis and their significance in clinical medicine were summarized, and the effects of environmental pollutants, particularly air pollutants, on DNA methylation were introduced. Furthermore, prospective applications of DNA methylation to environmental pollution detection and cancer prevention were discussed.
