Chemical Research in Toxicology: The Place for Chemists Curious about Contaminants

ACS-2833 Toxicology Axial 750x354

“‘Chemophobia’ is spreading,” says Janice E. Silverman, Acquisitions Editor of Chemical Research in Toxicology. “Everything is perceived as toxic.”

Many people may overestimate the dangers posed by “toxic” substances in their everyday lives, but toxicology research plays an undeniable role in our understanding of contaminants to the environment and living species.

“Toxicology tries to determine why a species suffers from exposure to a specific contaminant, looking at biological processes and pathways involved and the mechanism of actions,” Silverman explains. “Research and methods currently being developed in this field play an increasing role in the assessment of pollution, impact, and remediation.” 

Chemical Research in Toxicology is the prime source for scientists working on these problems. The journal publishes papers on the molecular mechanisms by which chemical and biological toxic agents interact with living systems to cause cellular damage. It also highlights studies on interactions of toxic agents with living systems. “It’s a venue for all aspects of the chemical basis of toxic responses,” Silverman says.

Chemical Properties, Environmental Fate, and Degradation of Seven Classes of Pollutants

Chem. Res. Toxicol.201427 (5), pp 713–737
DOI: 10.1021/tx500014w

Industrialization has benefitted civilization in many ways but has also caused irreversible changes to the environment that affect whole ecosystems. This Review covers polychlorinated biphenyls, halogenated hydrocarbons, estrogen analogues, phthalates, dioxins, perfluorinated compounds, and brominated flame retardants. These substances are among the most ubiquitous pollutants. The article presents the origins, chemical characteristics, intoxication mechanisms, detoxification pathways, environmental impacts, and degradation of these pollutants and their toxicological effects on humans and animals.

Changing Rates for Liver and Lung Cancers in Qidong, China

Chem. Res. Toxicol.201427 (1), pp 3–6
DOI: 10.1021/tx400313j

Residents of Qidong, China are undergoing rapid changes in the incidence rates of many types of cancer. This article examines the liver and lung cancer incidence rates tracked by the Qidong Cancer Registry for the past 40 years. Lung and liver cancer are the two leading cancer killers in Qidong, and both are influenced by environmental factors. The incidence rate for liver cancer has dropped significantly in the last 4 decades. On the other hand, lung cancer has increased among men in Qidong in the same time period, likely due to an increase in smoking. The rate of lung cancer was steady among women until the past decade, with the upturn possibly reflecting an increase in indoor and outdoor air pollution.

Combined Effects of Cadmium and UVB Radiation on Sea Urchin Embryos: Skeleton Impairment Parallels p38 MAPK Activation and Stress Genes Overexpression

Chem. Res. Toxicol.201528 (5), pp 1060–1069
DOI: 10.1021/acs.chemrestox.5b00080

Our oceans are currently being subjected to physical, chemical, and biological stressors caused by pollution. This article provides new information on the combined effects of UVB radiation and cadmium exposure on sea urchin development, looking at the induced malformation, gene activation, and protein activation. It contributes to the understanding of the molecular mechanisms adopted by embryos against multiple stress agents.

Seasonal Variation in Air Particulate Matter (PM10) Exposure-Induced Ischemia-Like Injuries in the Rat Brain

Chem. Res. Toxicol.201528 (3), pp 431–439
DOI: 10.1021/tx500392n

Air pollution is an important issue throughout the world, especially in the developing countries like China. Previous studies have shown correlations between levels of particulate matter (PM) and hospitalization for ischemic stroke. With air pollution worsening in China, the health risks caused by PM are becoming a serious concern. This article shows the effects of PM10 collected in different seasons in Taiyuan, China, looking at polycyclic aromatic hydrocarbons and carbon loading, and their possible association with brain ischemia-like injuries.
