BACKGROUND: Benzo(a)pyrene is a highly toxic substance which has been listed as a Group I carcinogen by the International Agency for Research on Cancer. There have been numerous studies by researchers worldwide on benzo(a)pyrene. Soxhlet, ultrasound-assisted, and liquid-liquid extractions have been widely used for the analysis of benzo(a)pyrene. However these extraction methods have significant drawbacks, such as long extraction time and large amount of solvent usage. To overcome these disadvantages, we aimed to establish a rapid residual analysis of benzo(a)pyrene content in agricultural products and soil samples. METHODS AND RESULTS: A Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) method was used as the pretreatment procedure. For rapid residual analysis of benzo(a)pyrene, a modified QuEChERS method were used, and the best codition was demonstrated after various performing instrument analysis. The extraction efficiency of this method was also compared with Soxhlet extraction, the current benzo(a)pyrene extracting method. Although both methods showed high recovery rates, the rapid residual analysis method markedly reduced both the measurement time and solvent usage by approximately 97% and 96%, respectively. CONCLUSION: Based on these results, we suggest the rapid residual analysis method established through this study, faster and more efficient analysis of residual benzo(a)pyrene in major agricultural products such as rice, green and red chili peppers and also soil samples.

This study examines consumers' perception of agricultural products using nuclear power plants waste heat. This study surveyed 348 consumers and found that presenting information about safety of waste heat utilization increased appropriacy of waste heat; after providing the information, the percentage of respondents in favor of using waste heat increased 27.5% point from 38.3% to 65.8%. The most important reason against using waste heat was because it threatened the safety of agricultural products, and the most important reason for its support was to reduce farm production costs. The purchase intention for agricultural products using waste heat had risen by at least 10% point after providing the information about safety of waste heat. Those means that it important provision of accurate and reliable information on the safety of waste heat to encourage the utilization of waste heat from nuclear power plants. Purchase intention for flowers using waste heat was most, followed by vegetables, fruits (including fruits and vegetables).

Investigations were made on the status of women groups on processing activities of agricultural products for the Hyogo prefecture in Japan. The data were analyzed with the Hideyosi for Windows(Version 1.19) and the Econometric View for Quantative Micro Softwere(Version 2.0). The results indicats that many rural women groups have their own experience on the activities of processing agricultural products and many other women groups have gained such experience from the management and establishment of the restaurants and direct sales stores. This kind of systems has influenced the activation of each rural district. Further development of the processing of agricultural products by rural women groups in the future demands better cooperation among diverse groups involved in these establishment centers and consumers. In addition, it is necessary to attract young people and train and upgrade them for successive consumers. (Korean J of Human Ecology 2(1) : 68∼79, 1999)

The purpose of this study is to analyze the school dietitian's cognition, practical use of environment-friendly agricultural products to provide fundamental information for the qualitative improvement in the school food service. The results of the study are as follows: 1. It was clearly recognized that the subsidy for the school food service is generally insufficient, the amount of additional appropriate subsidy for the school food service was different according to type of school and roughly 300~600 won in each of foods needs to be supported. 2. The environment-friendly agricultural products that were often used in the school food service were vegetables and grains. 3. In the analysis of cognition and problems toward using environment-friendly agricultural products, the dietitians recognized that environment-friendly agricultural products should be appropriately used. A reason that environment-friendly agricultural products were better than general agricultural products was composed of a use of less additive, good ingredient, and good outer condition. 4. In the analysis of countermeasure on increasing environment-friendly agricultural products in the school meal service, the response to that more additional subsidy was necessary for the school food service. The highest and the most positive effects after using environment-friendly agricultural products were students' health improvement and improvement in parents' satisfaction with the school food service.

Among the nutrients in feed, amino acids and minerals are important for the growth and development of pets. In particular, interest in nutritional components related to the health of pets is increasing as pet-raising households and pet food markets have recently grown. Therefore, in this study, 55 pet food products distributed in South Korea were purchased, and the content of 3 essential and conditionally essential amino acids (taurine, lysine, arginine) and 4 minerals (Ca, P, Na, K) was investigated. Among the three amino acids, arginine was found to have the highest content, and the average content was 1.79 and 1.37 % in cat and dog foods, respectively. On the other hand, the taurine content was the lowest, but it was found to be higher than the minimum requirement of 0.10 % for cats set by the American Association for Feed Control (AAFCO) and the European Federation of Pet Food Industries (FEDIAF). As a result of the four-component analysis of minerals, the content of Ca was found to be the highest, and the average content was confirmed to be 1.64 and 1.25 % in cat and dog food, respectively. On the other hand, Na was the lowest, but it was higher than the AAFCO minimum requirement and FEDIAF minimum requirement for young cat and dog food. Among all 55 samples examined, the content of the three amino acids and the four inorganic components was confirmed to be suitable for the recommended minimum intake and maximum allowable intake presented by AAFCO and FEDIAF.

This study investigated the online transaction status of low-carbon certified fresh agricultural products and analyzed the low-carbon certified premium. For two months from March to April 2022, eight products (rice, apple, pear, sweet persimmons, paprika, tomatoes, cherry tomatoes, and lettuce) were surveyed at major online shopping malls. The low-carbon certification premium was analyzed using hedonic price analysis model. As a result of the online market survey, the low-carbon certified agricultural products were not traded in the case of rice, cherry tomatoes, and paprika. And the proportion of low-carbon certified agricultural products in the case of tomatoes and lettuce was low. As a result of the low-carbon premium analysis, of the five products that analyzed the low-carbon certification premium, four products excluding pear did not have a low-carbon certification premium. Thus, it is necessary to expand the sale of the low-carbon certified agricultural products by distributors, and various efforts to secure the premium of certified agricultural products are important.

We studied an activation plan for utilizing eco-friendly agricultural products from agricultural producers' perspective through delphi techniques. Certification types of eco-friendly agricultural products held by producers were low-pesticide 26.1%, no-pesticide 39.1% and organic 52.2%. The major problems in handling the eco-friendly agricultural products were as follows: 'consumer distrust', 'lack of reliable and continuous shipping quantity' and 'lack of storage facilities, such as cold storage'. The major benefits of direct transactions between producers of eco-friendly agricultural products and processed food manufacturers including HMR processing companies were 'obtaining fresh food ingredients for processing' and 'confidence-building and income stabilization'. Regarding requirements for cooperation of eco-friendly agricultural producers and processed food manufacturers including HMR processing companies, the most common answers was 'multi-year contract based on trust'. When asked about governmental support for efficient cooperation between eco-friendly agricultural producers and processed food manufacturers including HMR processing companies, the most common answer was 'supporting plan for small producers' and 'arrangement for appropriate potential consumers'.
