[1] According to ECHA Guidance on Information Requirements and Chemical Safety Assessment; Chapter R.7a: Endpoint specific guidance, “…For the inhalation route, standard protocols involve a 4-hour exposure. Acute local effects are covered by the long term DNEL based on prevention of dermal sensitization. Seeds of corn (Zea mais) were put into Petri dishes on double filter paper together with suspensions from ferite containing nickel. less than 1/10 as common as the least common essential element, selenium), thus has low potential for any kind of biological role. Nickel concentrations in serum mainly reflect recent exposure because of the short biological half-time in this compartment.

Stanford Libraries' official online search tool for books, media, journals, databases, government documents and more. The core of the earth contains 8.5% nickel, deep-sea nodules 1.5%; meteorites have been found to contain 5–50% nickel (5). Biological effects data for tropical ecosystems were required to assess the risks of contaminant exposure and to derive appropriate water quality guidelines to protect our aquatic ecosystems and to ensure responsible nickel production in Southeast Asia and Melanesia. Acute systemic effects are not relevant due to the very low dermal absorption of nickel. Journal of Plant Nutrition: Vol. The purpose of this study was to investigate these effects and mechanisms, focusing on the nickel as a dental metal. Sunderman, F.W.
