The chemistry of intercepted clouds in northern Arizona during the North American monsoon season
Cloudwater samples have been collected for the first time at a high-elevation site in the US interior Southwest. Cloud samples were collected at the summit of Mt. Elden near Flagstaff, Arizona. The samples were analyzed for pH, ionic composition, trace metals, organic carbon content, and volatile organic compounds.
Environmental chemistry and ecotoxicology: in greater demand than ever
Environmental chemistry and ecotoxicology have been losing support, resources, and recognition at universities for many years. What are the possible causes of this process? Here, several cases are presented that illustrate the great demand for innovative research and teaching in environmental chemistry and ecotoxicology.
Environmental chemistry in the twenty-first century
Human society actually faces many environmental challenges such as environmental pollution, climate changes and loss of biodiversity. These issues induce major risks for ecosystems and are a serious threat for further life on Earth. Environmental chemistry is a central and multidisciplinary science that will provide new concepts and applied methods to solve actual environmental issues. Here, we outline the scope of environmental chemistry.
The environmental significance of chemistry variations in the rivers around Taiwan
Chemistry variations in the rivers are key indexes of weathering mechanisms. This paper presents a chemical variation examination of water samples acquired from 11 Taiwanese rivers to assess the relationships between chemical and physical weathering based on the variations of major dissolved ions.
The inorganic carbon chemistry in coastal and shelf waters around Ireland
The wintertime spatial distribution of carbonate parameters in outer estuarine and coastal waters around Ireland is described from total alkalinity (TA) and dissolved inorganic carbon (DIC) data collected between 2010 and 2013. The seasonal impacts on inorganic carbon chemistry was also investigated.
Potential CO2 intrusion in near-surface environments: a review of current research approaches to geochemical processes
This study reviews the geochemical processes related to the intrusion of CO2 into near-surface environments with an emphasis on metal mobilization and discusses about the geochemical research approaches, recent findings, and current knowledge gaps.
Recent sediments: environmental chemistry, ecotoxicology and engineering
An introduction is presented in which the editor discusses various reports within the issue on topics including environmental chemistry, interpretation of chemical tracers in sediments, and ecotoxicology and risk assessment.
Sustainable environmental chemistry and technology with focus on the Mediterranean area
The article presents introduction which discusses the scientific topics for sustainable environmental chemistry and technology and particulate matter in coastal urban area of Thessaloniki, Greece and removal of heavy metals.
Toward sustainable environmental quality: Priority research questions for Asia
Environmental and human health challenges are pronounced in Asia. Researchers identified and examined 23 priority research questions needed to advance toward more sustainable environmental quality in Asia, including advances in environmental toxicology and environmental chemistry.

Assessing the toxicity of mine‐water mixtures and the effectiveness of water quality guideline values in protecting local aquatic species
Six tropical freshwater species were used to assess the toxicity of mine waters from a uranium mine adjacent to a World Heritage area in northern Australia. Key contaminants of potential concern for the mine were U, Mg, Mn, and total ammonia nitrogen (TAN). Direct toxicity assessments were carried out to assess whether the established site‐specific guideline values for individual contaminants would be protective with the contaminants occurring as mixtures.
A critical review of organic ultraviolet filter exposure, hazard, and risk to corals
Organic ultraviolet (UV) filters are found in products like sunscreens and enter the aquatic environment via direct (i.e., recreational activities) or indirect (i.e., land runoff) pathways. This review summarizes the current state of the science regarding the concentration of organic UV filters in seawater and sediment near coral reef ecosystems and in coral tissues, toxicological data from early and adult life stages of coral species, and preliminary environmental risk characterizations.
Environmental chemistry and ecotoxicology of hazardous heavy metals: Environmental persistence, toxicity, and bioaccumulation
This article comprehensively reviews the different aspects of heavy metals as hazardous materials with special focus on their environmental persistence, toxicity for living organisms, and bioaccumulative potential. The bioaccumulation of these elements and its implications for human health are discussed with a special coverage on fish, rice, and tobacco.
Management of PFAS with the aid of chemical product registries—an indispensable tool for future control of hazardous substances
Nordic countries are in the forefront of international chemical regulation and management. A key tool in their work has been the product registries (PRs), where all chemicals imported and produced over a certain reporting limit must be registered by the importers and/or producers. This paper explores the role of PRs in national and international chemical management.
Mercury exposure and toxicological consequences in fish and fish‐eating wildlife from anthropogenic activity in Latin America
Despite the risk of significant adverse toxicological effects of mercury (Hg) to humans and wildlife, Hg use in anthropogenic activities, and artisanal small‐scale gold mining (ASGM) in particular, is widespread throughout Latin America. In this paper, researchers reviewed the literature from published articles and reports and summarized and assessed data on Hg in fish from 10,391 individuals and 192 species sampled across Latin America.
Toxicity of nanoparticulate nickel to aquatic organisms: Review and recommendations for improvement of toxicity tests
In this paper, researchers reviewed the literature on toxicity of nanoparticulate nickel (nano‐Ni) to aquatic organisms, from the perspective of relevance and reliability in a regulatory framework.
