The relationship between dirt and fungal contamination in bathrooms and the effect of cleaning were examined. Levels of dirt were higher on the floor than on the wall, although the number of fungi was smaller. Factors other than fungal contamination, including bacteria and dust, may play an important role in the development of floor dirt. Exophiala in particular, more than Cladosporium, Rhodotorula, and other species, seemed to affect dirt levels on both

Osaka City has addressed the resolution of solid waste problems from the middle of Meiji era, and conducted fullscale research on disposal in the middle of Taisho era. It was the first time that City analyzed solid waste in detail within the research. City also analyzed solid waste in Showa era for the study of disposal method. In this study, experimental separate collection was implemented and separated solid wastes were analyzed. The Osaka Municipal Hygienic Laboratory took charge of analysis in those researches, and also analyzed solid waste independently. After the World War II, when City introduced continuous incineration plant from Europe, the Laboratory compared the conventional method of solid waste analysis with the method introduced from Europe, and found that there was little difference between two methods, and have established the analytical method that has been used until now. In the material, the results of solid waste analysis conducted in those studies are shown.

In the area of general foods, phytosterols are mainly present in vegetable oils, but it is not known to what degree these oils can contribute to the reduction of plasma cholesterol because the amount used in cooking is limited. In the present study, to investigate the contribution of vegetable oils to dietary phytosterol content, take-out lunches were selected as model meals and divided into three groups based on the amount of vegetable oils in the main dish: a deepfried dish group, a stir-fried dish group and a boiled or baked dish group. Even in the deep-fried group, which had the highest vegetable oil content, average phytosterol content was 49.2 mg/diet, which was much smaller than the value calculated by adding together the individual values for phytosterol contained in foodstuffs consumed daily. The boiled or baked dish group, meanwhile, which had the lowest phytosterol content, contained 33.5 mg/diet, which seemed to originate mainly in the vegetables and cereals themselves. The cholesterol content and cholesterol/phytosterol ratio were similar in the three groups and there was no significant correlation between cholesterol and phytosterol content in any of the groups.

A mass fish death occurred at Minami-Sotobori (moat) in Osaka-Jo Park on Oct. 4, 2007. It was reported that more than a thousand fish died. Features of the mass death were: 1) it involved many of the fish species that live in the moat, 2) most were fish with long body length and died with open mouth, 3) dissolved oxygen was 3.1 mg·L-1 or less throughout the water column. It was judged that the fish had died of anoxia. The air temperature had decreased rapidly seven days before the fatal accident and low temperatures continued for four days. As a result, it is thought that the epilimnion was cooled strongly and sank to the bottom during this period and that the hypolimnion, which contains less oxygen, welled up. Since the hypolimnion seems to become anaerobic under organic loading for long periods, it is possible that similar accidents will happen again when water stratification breaks down for some reason.

The fungal flora of bathrooms was examined using a modified medium. PDA medium consisting to one-fourth of nutrient was used for detecting fungi. This low-nutrient medium was thought to be convenient for detecting slowgrowing fungi while suppressing fast-growing yeast. Heavy fungal contamination was found on toys, soap dishes, and in the drain mouth. Characteristic mold genera in the bathrooms were Exophiala, Cladophialophora, Phoma and Scolecobasidium, which, in contrast to elsewhere, were more predominant than Cladosporium and Acremonium inside bathrooms. Cladophialophora in particular is not common in indoor environments, and the specimen was identified using genetic data. Of the yeasts, Rhodotorula was predominant in all areas of the bathroom. Molds characteristically found in bathrooms were similar to those found inside washing machine using detergent. Exophiala, Phoma, Cladophialophora and Scolecobasidium were also predominant in the lower areas and in unit-type bathrooms. In contrast, Cladosporium and Aureobasidium were predominant in the upper areas of the bathroom in all seasons and seemed to use glycerides derived from human skin as nutrient. Also discussed are factors affecting the differing distribution of Cladosporium, Exophiala, and other molds.
