Polycyclic Aromatic Hydrocarbons in Soil and Human Health Risk Levels for Various Land-Use Areas in Ulsan, South Korea

Multiplicity and complexity in sources account for polycyclic aromatic hydrocarbons (PAHs) in soil and health risk levels in industrial zones. In the present study, cancer risks (CR) for soil-bound carcinogenic PAHs were estimated and compared for the first time in seven different land-use areas adjacent to an industrial zone (Ulsan) in Korea. The entire study area has been recognized as a “low CR” zone (10−6 < value < 10−4). Hence, all land-use areas were found to have significant (>10−6) CR levels, except for an area used to store ore and iron scraps. Estimated CR levels were highest in the railroad area (RA) and traffic area (TA), followed by those in the industrial area (IA). In addition, exposure through dermal absorption (61–70%) and ingestion (21–39%) were the most common factors for CR levels in the study area. Among all health parameters, exposure duration, body weight, and open skin surface area were distinguished as most sensitive to total CR levels. Moreover, among all carcinogenic PAHs, indeno[1,2,3-c,d]pyrene and benzo[a]pyrene were most sensitive to CR levels. Creosote, which was utilized in railroad ties in RA and vehicular exhaust emission in TA, was classified as a source of soil-bound carcinogenic PAHs. Therefore, CR levels resulting from transportation activities were found to be two to three times higher than those obtained from industrial processes. Transportation activities in urban areas mostly serve to provide rapid and comfortable carriage for commuters. However, these facilities were mostly responsible for potential carcinogen exposure. This study directly challenges the conventional perception that industrial zones are the most polluted areas, especially when compared to transportation zones in urban areas. These findings can help local and national governments to better manage resources and maintain an economic balance.

Development of Creative Handicrafts Industrial Zones in Rajapolah District, Tasikmalaya Regency: Spatial Recommendation for Village Areas

The creative craft industry in Rajapolah District as the main driver of the regional economy in supporting facilities that still concentrated in one particular area. There have been limited studies concerned on spatial functions in creative spaces. This article addresses the criteria for functions and facilities for the development of creative industrial areas and their application in spatial recommendation for village areas. This research used a quantitative method using instruments on statistical data. Data analysis was divided into three stages namely identification, determining the criteria, and determining spatial functions. The study used the form of production data includes raw materials, labor, product size, product diversity, as well as the distribution of production houses, marketing facilities and education and training. The results showed that the development of creative industrial zones can be identified on criteria functions in the provision of raw materials, production, research and development, and marketing. Some villages have fulfilled the criteria for the function of creative spaces, which are relatively scattered in craft production houses close to the center of village activities. Besides that, it is also relatively far away, however supported by adequate road access. Creative promotion centers in the form of markets, outlets and shops are mostly concentrated on the main road network. Meanwhile, creative education centers in the form of multi-purpose building are relatively concentrated in some villages. Articles contribute to the field of creative industry science which is practically used as a consideration for the government in preparing detailed urban masterplans.

Employing spider webs for environmental investigation of suspended trace metals in residential and industrial areas

Spider webs were gathered from residential and industrial areas to found the order of heavy suspended metals in the air. The treatment of spider webs were done with nitric acid and digested by atomic absorption spectrophotometer before analysis (AAS). The average value of several heavy metals concentration were observed to be meaningfully great at p < 0.05 in suspended ingredients in industrial zones including, Cadmium (Cd) 0.15 ± 0.05 and Lead (Pb) 0.53 ± 0.09 µgg-1, respectively. The average values of concentration of Copper (Cu), Nickel (Ni) and Zinc (Zn) were not meaningfully changed from residential, industrial and control zones. It was observed that, the heavy metals concentration reduces when the web specimens were collected more away from the road.

MONITORING THERMAL POLLUTION SOURCES IN VORONEZH (RUSSIA) USING REMOTE SENSING DATA

Рассмотрены вопросы мониторинга теплового загрязнения окружающей среды в городах. Представлена методика отбора спектрозональных спутниковых снимков, их обработки и интерпретации полученных результатов. Для оценки городского острова тепла были использованы снимки с космического аппарата Landsat 8 TIRS. На их основе построены карты пространственной структуры острова тепла города Воронежа за летний и зимний периоды. Определены тепловые аномалии и выявлено 11 основных техногенных источников теплового загрязнения в г. Воронеже, установлена их принадлежность к промышленным зонам предприятий, а также к очистным гидротехническим сооружениям. Поверхностные температуры данных источников в среднем были выше фоновых температур приблизительно на 6° зимой и на 15,5° С летом. Синхронно со спутниковой съемкой были проведены наземные контрольные тепловизионные измерения температур основных подстилающих поверхностей в г. Воронеже. Полученные данные показали высокую сходимость космических и наземных измерений, на основании чего сделан вывод о надежности используемых данных дистанционного зондирования Земли в мониторинговых наблюдениях теплового загрязнения городской среды. Результаты работ могут найти применение в городском планировании и медицинской экологии. The study deals with the remote sensing and monitoring of urban heat islands. We present a methodology of multispectral satellite imagery selection and processing. The study bases on the freely available Landsat 8 TIRS data. We used multitemporal thermal band combinations to make maps of the urban heat island of Voronezh (Russia) during summer and winter periods. That let us identify 11 artificial sources of heat in Voronezh. All of them turned out to be allocated within industrial zones of plants and water treatment facilities. Land surface temperatures (LST) of these sources were approximately 6° and 15.5° C above the background temperatures in winter and summer, respectively. To prove the remotely sensed temperatures we conducted ground control measurements of LST of different surface types at the satellite revisit moments. Our results showed a significant correlation between the satellite and ground-based measurements, so the maps we produced in this study should be robust. They are of use in urban planning and medical ecology studies.

DOMESTIC AND FOREIGN TYPES OF REDEVELOPMENT OBJECTS FOR HOUSING

Manufacturing has historically been the driving force behind economic growth and structural change. During the financial and economic crisis, governments in Europe provided short-term assistance to industries that had fallen into disrepair by converting them into market-oriented industries (such as steelmakers and car manufacturers). As cities grow and the density of megacities increases, the need for their "renewal" began to appear, which is characterized by the transformation of non-functional buildings and old abandoned buildings for the purpose of further operation. The state and private organizations were interested in the transformation of such territories and actively invest in these projects. Industrial complexes are transformed into areas with residential apartment buildings and offices, their own social infrastructure, transport, entertainment reflecting the needs of modern society. In the future, urban areas can benefit greatly from new opportunities. All over the world, industrial territories are an integral part of cities. The article discusses the experience of reconstruction of industrial zones in Russia and abroad. The industrial heritage is adapting to the new context of the city, using the principles of sustainability, economy and aesthetics

Sexual Risk Behaviors, HIV Prevalence and Access to Reproductive Health Services Among Young Women Migrant Workers in the Industrial Zones in Vietnam

Background: Young migrant workers working in the industrial zones (IZ) in low and middle-income countries are at risk for HIV and other sexually transmitted diseases. This study examines the sex-related risks of young women migrant workers in the IZ in Vietnam.Materials and Methods: This cross-sectional survey was conducted among 1,061 young migrant women working in the IZ park in Hanoi, Vietnam. Multivariate logistic regression analysis was used to identify factors associated with HIV testing and condom use at last sex.Results: A total of 1,061 young women migrant workers completed the survey in which 652 participants consented to take the initial rapid HIV test. All but one participant tested negative indicating a HIV prevalence of 150 (95% CI: 27–860) per 100,000 population among this population. There were no differences in sexual behavior, use of sexual and reproductive health services, HIV knowledge, perceived HIV risk or alcohol use between those who were HIV tested and those not tested. Single participants reported high rates of first sex while living in the IZ and high rates of condom use during the first-time sex, however, they had low levels of condom use at last sex. While the majority of married participants used the SRH/HIV services, nearly 80% of the single participants who reported having sex never used SRH/HIV services since living in the IZ. However, single participants were over 4 times more likely to use condoms at last sex compared to married participants (OR = 4.67; 95%CI = 2.96–7.85). Participants with vocational school or higher education was more likely to use condom (OR = 2.19; 95%CI = 1.05–4.57). Neither HIV knowledge or alcohol use were associated with condom use.Conclusions: Although HIV prevalence is very low among young women workers in the IZ in Vietnam, a significant number of them engaged in risky sexual behavior and low levels of condom use at last sex as well as low level of using SRH/HIV services highlights a need to develop interventions that provide tailored-made and cultural appropriate SRH education for unmarried female migrant workers to prevent risky sexual behaviors, sexually transmitted diseases and unwanted pregnancy.

Features of the negative impact of modern infrastructure facilities in urbanized areas on the environment

In the paper, the authors analyze the impact of modern infrastructure facilities in urbanized areas on the quality of the environment. The first stage of the study was to consider the changes in the urban environment of recent decades, which consists in the transformation of many former industrial zones into large objects of a cultural and entertainment nature, namely shopping and entertainment centers (SEC) or complexes (SECo). The authors also pay special attention to the description of the structural diagram of typical SEC or SECo, the main sources of negative environmental impact from them, as well as directly to the types of these impacts. The analysis carried out confirmed that it would be wrong to say that the quality of the environment in urbanized areas has improved due to the replacement of industrial facilities within cities with SEC or SECo. The authors consider the further task of scientific research to be the process of constructing physical models of pollution processes and reducing air pollution for individual sources for the purpose of subsequent analysis and highlighting promising directions (methods and options) for implementing a system for combating pollution.
