  • Hormesis: Why it is Important to Toxicology and Toxicologists - Critical Review

    This article provides a comprehensive review of hormesis, a dose–response concept that is characterized by a low-dose stimulation and a high-dose inhibition. The article traces the historical foundations of hormesis, its quantitative features and mechanistic foundations, and its risk assessment implications. The article indicates that the hormetic dose response is the most fundamental dose ...

  • On the road from environmental biomonitoring to human health aspects: monitoring atmospheric heavy metal deposition by epiphytic/epigeic plants: present status and future needs

    For the past few years, a strong and intensive combined study by analytical scientists and biologists on bioindication and biomonitoring has developed. To achieve a more public-related prophylactic healthcare feature derived from these biotechniques in the future, the collaboration between analytical scientists, ecotoxicologists and especially human toxicologists has to be strongly intensified ...

  • An assessment and perception of the hazards of pesticide use in the aquatic environment

    Various models are available to help assess the risk of chemicals to the aquatic environment. The hazard posed by pesticides in use in Prince Edward Island, Canada was estimated by a model based on fugacity. Groups of individuals currently working in the field of aquatic toxicology were asked to rank 20 of these pesticides in order of decreasing hazard. There is little agreement between ...

  • How do aquatic communities respond to contaminants? It depends on the ecological context

    Context dependency refers to variation in ecological patterns and processes across environmental or spatiotemporal gradients. Research on context dependency in basic ecology has focused primarily on variation in the relative importance of species interactions (e.g., competition and predation) among communities. In this Focus article, the authors extend this concept to include variation in ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...
