Nine-volt battery batteries were formerly made in this size. They had higher capacity than the then-standard carbon-zinc types, a nominal voltage of 8.4 volts, and very stable voltage. Once used in photographic and measuring instruments or long-life applications, they are no longer manufactured as mercury is highly toxic and accumulates in the ecosystem, posing a risk to humans and wildlife. Most battery voltage testers and chargers that can also test nine-volt need another snap clip to hold the battery, while cylindrical batteries often share a holder that may be adjustable in size. Because of the proximity of the positive and negative terminals
Hungarian Food Safety Office was the scientific risk assessment relating to food safety, taking into account up-to-date scientific findings of recognised international institutions. The scientific risk assessment is based on identifying potential hazards, defining their characteristics, assessing their incidence and frequency and describing the risk. HFSO is responsible for assessing risks relating to concrete events, furthermore by analysing the data of annual official inspections concerning various agricultural, technological, environmental and biological contaminants, pesticide residues and natural toxic substances in raw and processed food. Based on the risk assessment, it forwards a proposal concerning the priority of inspections in the forthcoming period and participates in
