  • Hydrophilic polymer is suitable as soil conditioners for green roofs that use rainwater, due to promotion of water retention capacity as well as enhancement of the water absorbing capacity. The objective of the present study was to investigate the effects of different levels of hydrophilic polymer concentrations (0, 0.1, 0.2, 0.4, 0.8% w/w) on the water holding capacity and growth response of 6 species in soils amended with hydrophilic polymer in 5 cm of soil thickness on green roofs. The results showed that the water holding capacity of the amended soil improved with increasing amount of applied polymer. The application of 0.8% w/w of the polymer increased the soil moisture by 87% compared to the control, and decreased slowly in green roofs during an arid period. The growth of Sedum spurium 'Dragon's blood' and Lampranthus spectabilis increased significantly and had greater than 60% relative coverage with higher hydrophilic polymer concentrations. However, Juniperus chinensis var. sargentii and Euonymus fortunei var. radicans had no significant differences upon change of hydrophilic polymer concentrations. In Carex kujuzana and Carex morrowii 'Aurea variegata', growth decreased with increase of hydrophilic polymer concentrations. 30 days after planting, Juniperus chinensis var. sargentii, Euonymus fortunei var. radicans, Carex kujuzana, and Carex morrowii 'Aurea variegata' died back due to lowest soil thickness (5 cm), but Sedum spurium 'Dragon's blood' and Lampranthus spectabilis had greater than 90% survival.

  • Lead is ubiquitous in the human environment as a result of industrialization. China's rapid industrialization and traffic growth have increased the potential for lead emissions. Lead poisoning in children is one of the most common public health problems today, and it is entirely preventable. Children are more vulnerable to lead pollution and lead in their bodies can affect their nervous, circulatory, and digestive systems. Children are exposed to lead from different sources (such as paint, gasoline, and solder) and through different pathways (such as air, food, water, dust, and soil). Although all children are exposed to some lead from food, air, dust, and soil, some children are exposed to high dose sources of lead. Significant sources of lead for China's children include industrial emissions (often close to housing and schools), leaded gasoline, and occupational exposure that occurs when parents wear lead-contaminated clothing home from work, burning of coal for home heat and cooking, contaminated food, and some traditional medicines. To assess the blood lead level in children in China, a large-scale study was conducted in 19 cities among 9 provinces during 1997 to 2000. There were 6502 children, aged 3-5 years, were recruited in the study The result indicates that the mean blood lead level was 8.83ug/dl 3-5 year old living in city area. The mean blood lead level of boys was higher than that of girls (9.1l ug/dl vs 8.73ug/dl). Almost 30 percent childrens blood lead level exceeded 10ug/dl. The average blood lead level was higher than that of in 1985 (8.83ug/dl vs 8.lug/dl). An epidemiological study was carried on the children living around the cottage industries recycling the lead from battery. Nine hundreds fifty nine children, aged 5-12 years, living in lead polluted villages where the lead smelters located near the residential area and 207 control children live in unpolluted area were recruited in the study. The lead levels in air, soil, drinking water and crops were measured. The blood lead and ZnPP level were tested for all subjects. The results show that the local environment was polluted. The lead levels both in the air and crops were much higher than that of in control area. In the polluted area, the average blood level was 49.6ug/dl (rang 19.5-89.3ug/dl). Whereas, in the unpolluted area, the average blood level was 12.4ug/dl (rang 4.6-24.8ug/dl). This study indicates that in some countryside area, some cottage industries induce seriously lead pollution and cause children health problem. For the introducing of unleaded gasoline in some large cities, such as Beijing and Shanghai, the blood lead level showed a declined trend since 1997. By 2000, the use of leaded gasoline in motor vehicles has been prohibited in China. The most recent data available show that levels of lead in blood among children in Shanghai decreased from 8.3ug/dl in 1997 to 7.6ug/dl in 1999. The prevalence rate of children lead poisoning (blood lead >10ug/dl) was also decreased from 37.8% to 24.8%. In children living in downtown area, the blood lead level reduced dramatically. To explore the relationship between gene polymorphisms and individual susceptibility of lead poisoning, a molecular epidemiological study was conducted among children living in lead polluted environment. The result showed that the subjects with ALAD2 allele has higher ZPP level, and the subjects with VDR B allele has larger head circumference than only with b allele. In the present study, we demonstrated that ALAD genotypes modify lead effects on heme metabolism and VDR gene variants influence the skull development in highly exposed children. The polymorphism of ALAD and VDR genes might be the molecular inherited factor modifying the susceptibility of lead poisoning. Recently, Chinese government pays more attention to lead pollution and lead poisoning in children problem. The leaded gasoline was prohibited used in motor vehicles since 2000. The government has decided to have a clampdown on the high-polluted lead smelters for recycling the lead from battery in countryside. It is hopeful that the risk of lead poisoning in children will be decreased in the further

  • The effects of protease and/or lipase on the removal of protein soil and oily soil were investigated in this study. Cotton, rayon, nylon, and PET fabrics were soiled by padding of fresh bovine blood and spotting of mixed artificial sebum evenly. The soiled fabrics were aged at $130^{\circ}C$ for 30 minutes. The fabrics were washed by using Terg-O-Tometer at various conditions. Protease and/or lipase were added in the alcohol ethoxylate (AE) detergent solution. The removal efficiency was evaluated by analysis of protein and/or oil on the fabrics before and after washing, respectively. The detergency of protein and/or oil on the fabrics was discussed with enzyme concentration, washing time, washing temperature, pH of washing solution and fiber characteristics. The hydrolysis of protease improved effectively the removal of oil as well as protein by increasing removal of protein-oil mixed soil at the same time. The effect of lipase added detergent solution was slightly shown on the removal of oil and/or protein. The removal of mixed soils from cotton fabrics was very low because of large amount of residual soils caused by the physical characteristics of cotton fiber.

  • This study aims to present basic data on long-term sexual effects of Savory (Satureja hortensis) by analyzing its zinc and V.B3 contents. These contents result in the activation of sexual functions induced by the blood concentration of sex hormones, thus improving menopauale symptoms. Results were obtained on August 20, 2020 after experimenting with 100 g of the herb from six indoor (green-house) experimental plots. The V.B3 results were analyzed using 100 g of Savory planted in open soil. Zinc had the highest values at 2.161 mg from the bed soil compounded with sapolite and poultry manure in the indoor condition and 2.077 mg from bed soil mixed with clay in the outdoor condition. The presence of V.B3 in Savory was also confirmed. Further research should be conducted on the interactions between Savory and other herbs.

  • The dry cleaning effect related to the type of soil and fiber was analyzed using silicone and alcohol-based solvents(ethyl alcohol, isopropyl alcohol, acetone) that are relatively safe for the human body and environment to improve the detergency of hydrophilic soils in dry cleaning system. Based on this analysis, an effective dry cleaning method to be carried out for improving the detergency according to the type of hydrophilic soils. After dry cleaning was performed using 20 types of artificial soiled fabrics consisting of 7 types of fibers and 4 types of hydrophilic soils, the detergency was measured and the results were compared and analyzed by solvents and fiber types. The results are presented as follows; first, the detergency of hydrophilic soils using silicone solvents showed a low rate of detergency. In particular, the tannin soil showed a lower level of detergency compared to the protein soil. Second, the detergency of hydrophilic soils using silicon solvents with dry soap differed in some detergency according to the soil and fiber types. Especially, the detergency of curry soil on cotton fabric showed significant improvement. Third, the protein soil was not removed from dry cleaning using alcohol-based solvents, but the effect of dry cleaning of curry soil on both cotton and polyester fabric was substantially improved. As a result, the elimination of blood soil is more effective in silicon solvents than in alcohol-based solvents. The removal of tannin soils may improve detergency by adding dry soap to silicon solvents or by using alcohol-based solvents as alternative solvents. The use of alternative solvents such as silicon and alcohol solvents can contribute to the environmental improvement of the dry cleaning industry, which uses petroleum-based solvents. It is also expected to provide consumers with the opportunity to choose eco-friendly and efficient dry cleaning methods.

  • A robust approach was conducted to determining the absolute oral bioavailable (fab) fractions of 238U and 232Th in rats exposed to contaminated soil along with their hematotoxicity and nephrotoxicity. The soil sample is the International Atomic Energy Agency-312 (IAEA-312) certified reference material, whereas blood, bones, and kidneys of in vivo female Sprague-Dawley (SD) rats estimate 238U- and 232Th-fab fractions post-exposure. We predict the bioavailable concentration (Cab) and fab values of 238U and 232Th after acute soil ingestion. The blood 238U (0.750%) and 232Th (0.028%) reach their maximum fab values after 48 h. The 238U (fab: 0.169-0.652%) accumulates mostly in the kidney, whereas the 232Th (fab: 0.004-0.021%) accumulates primarily in the bone. Additionally, 238U is more bioavailable than 232Th. Post 48 h acute ingestion demonstrates noticeable histopathological and hematological alterations, implying that intake of 238U in co-contaminated soil can lead to erythrocytes and proximal tubules damage, whereas, 232Th intake can harm erythrocytes. Our study provides new directions for future research into the health implications of acute oral exposures to 238U and 232Th in co-contaminated soils. The findings offer significant insight into the utilization of in vivo SD rat testing to estimate 238U and 232Th bioavailability and toxicity in exposure assessment.

  • Four different subtilisins of protease were investigated to see their effects on the cleaning activity. The cleaning solution was formulated with various non-ionic surfactants and other additives such as propylene glycol, triethanolamine, pH balancer etc. to evaluate their effect on enzyme activity as well. Evaluation of formulated cleaning solution was carried under K0120 using pre-soiled textiles from EMPA. The results showed that the cleaning activity on soil removal was not severly influenced by surfactant but the enzyme mostly. In addition, the activity of enzymes was not much affected by the type of surfactants as long as the surfactants were non-ionic. Liquinase among the four enzymes used in this study showed the best performance on soil removal, especially blood stain.

  • A study was conducted to determine the macromineral status of grazing cattle in three climatic regions of the province of South Sulawesi, Indonesia. Soil, forage, blood and rib bone samples were collected within the Western, Central and Eastern regions, respectively, in February-March and August-September of 1987. Calcium and magnesium were not deficient in soil samples. For forages, calcium and phosphorus were deficient for all regions and forage sodium was deficient except for the western region in the dry season. Crude protein was deficient during the dry season. The overall percentage of deficient plasma phosphorus samples was 17 or 23% for the wet and dry seasons, respectively. Based on these analyses, macrominerals most likely deficient in both seasons were phosphorus and calcium in all regions, in addition to sodium in the Central and Eastern regions.
