Environmental toxicology is one of the most interdisciplinary subjects which use the toxicological methods to study the effects of the harmful toxicants in the environment on living organism. It studies the deleterious effect of environmental pollutants mainly through animal experiments. Its main task is to study the possible biological effect that the environmental pollutants might have on organism and affect the detection index of mechanism and early damage to provide scientific basis for the making of the environmental sanitation standard and the implementation of environmental protection work. Biologists, microbiologists, chemists, engineers, environmentalists, ecologists, and other scientists have worked hand-in-hand within this new discipline. There is a growing need for techniques and practices to minimise the environmental effects of chemicals for the implementation of the corresponding principles in the planning of environmental policy and decision making.

In this special issue, it is intended to invite frontline researchers and authors to submit original research and review articles on exploring environmental contamination and toxicity.

Potential topics include, but are not limited to:

• Biomarkers for environmental pollution monitoring
• Effluent toxicity and performance of wastewater treatment plants and solid waste disposal facilities
• Bioaccumulation of chemicals
• New trends in environmental toxicology
• New trends in water quality monitoring
• Bioassays and biomarkers in water monitoring programmes
• Bio monitoring of water bodies
• Ecological footprints
• Ecotoxicity of emerging chemicals
• Biological effects monitoring
• Laboratory techniques and field validation
• Quantitative structure–activity relationships (QSAR)
• Ecosystem health and environmental health risk assessment
