Summary
Radioactive cerium-144 was detected in Japanese food and animal bone samples. Clams from Hinuma Marsh showed the highest radioactivity, likely due to fallout.
Area of Science:
- Environmental Science
- Radiochemistry
- Ecotoxicology
Background:
- Radioactive isotopes can enter the food chain.
- Environmental monitoring is crucial for public health.
- Fallout from nuclear events can contaminate ecosystems.
Purpose of the Study:
- To investigate the presence and distribution of cerium-144 in environmental samples.
- To identify potential sources of radionuclide contamination in Ibaraki, Japan.
Main Methods:
- Radiochemical analysis of food and animal bone samples.
- Radioactivity measurement using appropriate detection techniques.
- Geographical sampling in Ibaraki, focusing on Hinuma Marsh.
Main Results:
- Detection of small amounts of cerium-144 in various food and animal bone samples.
- Highest radioactivity levels of cerium-144 found in clams (Schizimi, Corbicura sp.) from Hinuma Marsh.
- Widespread occurrence of cerium-144 suggests a common source.
Conclusions:
- Cerium-144 contamination is present in the environment of Ibaraki, Japan.
- The radionuclide's widespread distribution points to atmospheric fallout as the likely source.
- Clams from Hinuma Marsh are significant bioaccumulators of cerium-144.

01:30Vitamins
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
01:26Minerals
Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.
01:27Microorganisms in Agriculture and Food industry
Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...
01:23Microbial Spoilage of Food
Microbial food spoilage refers to the degradation of food quality resulting from the metabolic activity of microorganisms such as bacteria, yeasts, and molds. These microbes proliferate on various food substrates depending on factors such as moisture content, nutrient availability, and storage conditions, leading to undesirable sensory and structural changes.Bacteria are primary agents of spoilage in high-moisture, nutrient-dense foods like meat, milk, and vegetables. Microbial spoilage occurs...
01:27Principles of Food Preservation
Food spoilage results from microbial growth, enzymatic activity, and environmental factors that gradually degrade the sensory, nutritional, and safety qualities of food. Preservation techniques aim to slow or halt these processes to extend shelf life and maintain product quality.A key concept in food microbiology is the microbial growth curve, which includes four phases: lag, exponential (log), stationary, and death. During the lag phase, bacteria adjust to their environment without significant...
01:26Methods of Controlling Food Spoilage
Food spoilage is caused by microbial growth or by chemical and physical changes, all of which affect the taste, texture, and safety of food.Temperature-Based PreservationRefrigeration at 0–4 °C slows microbial growth and enzyme activity, making it ideal for short-term storage. However, certain spoilage organisms—such as psychrotrophs like Listeria monocytogenes—can still proliferate at these temperatures. Freezing below -18 °C further slows biological processes by forming ice crystals, which...
