Chemicals, especially synthetic chemicals, might post poten-tial risks to ecosystem and human health if they excessivelyexist in the environment due to overuse, accidental spill,accumulation, and so forth. Therefore, it is urgent andimportant to explore the chemicals in the environment. Thisspecial issue is aimed at providing useful information on ana-lytical methods for monitoring harmful chemicals in variousenvironments, pollution control processes and technologiesfor harmful chemicals, the fate of harmful chemicals innatural and engineered environments, and ecological risksposed by the harmful chemicals. Therefore, some submittedarticles are selected to show the current research frontiersin measurement, fate, ecological risks, and remediation ofharmful chemicals in the environment.

Nutrient control was extensively explored. Therefore, theinfluences of different controlled irrigation and drainageconditions on dynamics of nitrogen (N) and phosphorus (P)were studied by S. Gao et al. and J. Cui et al. Controlledirrigation and drainage seemed to be an efficient method forcontrolling N and P.

Removal of heavymetal in water was tried using differentmethods. Y. Guo et al. reported a novel approach for remov-ing aqueousCu(II).They adoptedwheat strawwith alkali pre-treatment to adsorb Cu(II) under acidic condition and opti-mized alkali pretreatment conditions. J. Liu et al. investigatedadsorption properties of Cr(III) or Cr(VI) in the absence andpresence of Cu(II) onto kaolin under pH of 2.0–7.0. Theyfound that pH played a critical role in kaolin zeta potential.

Studies on organic pollution control were performedthrough different aspects. G. Zhu et al. used biologicalpretreatment reactors to remove organic pollutants fromeutrophic water of Lake Taihu. Biological contact oxidationreactors-cascade biofilm reactor (CSBR) was proved to beefficient in low-molecular-weight organic pollution. X. Bianand J. Zhang explore photodegradation of sulfadiazine underultraviolet (UV) light. The degradation of sulfadiazine inwater followed the first-order kinetics with a half-life of8.44min. Y. Dong et al. studied the promotion effect ofmethanoic acid onphotoelectrocatalytic degradation of fulvicacid. They also discussed the degradation mechanism. S. Liuet al. focused on the natural degradation and ecotoxicity ofnonivamide in seawater and tap water.

Ecological risks posed by pollutants were also paidattention to. J. Hussain et al. studied temporal distributionand ecological risk of polycyclic aromatic hydrocarbons insediments of Changdang Lake, China.

Z. Xu et al. brought us new knowledge on chemicalsin the tailings dam. They paid attention to permeabilitycharacteristics of tailings during chemical-physical cloggingprocess.

The articles of this special issue contributed to new infor-mation on monitoring, fate, risks, and treatment of harmfulchemicals in the environment. We hope this special issue willhave a long-term impact in the field of the environmentalchemistry and technology.
