A mass production test of tsukuritake mushrooms ( Agaricus bisporus ) that can be cultivated in compost was conducted to develop a new utilization method for sewage sludge compost. The fruit body yield was 1350 ± 230 g/container in the test plots using sewage sludge compost/cow manure, which was comparable to the control plot using horse manure compost. In the test plots using sewage sludge compost, the amount of free amino acids in fruit bodies increased by 50-70 % compared to the control plots. Furthermore, heavy metal analysis of fruiting bodies showed the detection of Cd and T-Hg in fruit bodies in the test plots using sewage sludge compost. Judging from the acceptable values for agricultural products and the content of heavy metals in domestically grown mushrooms, however, the values of the fruit bodies cultivated in this test were judged to have no effect on health. The waste fungus bed was subjected to a cultivation test of komatsuna ( Brassica rapa var. perviridis ), and it was found that the mushroom waste bed containing sewage sludge compost and cow dung compost especially grew more than the section with chemical fertilizer application and could be used as a partial substitute for fertilizer.
为开发污水污泥堆肥利用新途径，对可在堆肥中栽培的土菇(Agaricus bisporus)进行了批量生产试验。污水污泥堆肥/牛粪试验小区的果体产量为1350±230 g/容器，与马粪堆肥对照小区相当。在施用污泥堆肥的试验区，果实中游离氨基酸的含量比对照区提高了50 ~ 70%。此外，子实体重金属分析显示，在使用污水污泥堆肥的试验田，子实体中检测到Cd和T-Hg。然而，从农产品可接受值和国产蘑菇重金属含量来看，本次试验培养的果实体值对健康没有影响。对废弃菌床进行了小松菌(Brassica rapa var. perviridis)的栽培试验，发现含污泥堆肥和牛粪堆肥的菌床比施用化肥的菌床生长得更好，可以部分替代化肥。

The Ministry of Environment Notification has defined no analytical method for recycled material resources. However, because an appropriate resource evaluation system is necessary, we compared the contents of WEEE and molten metal found using several methods. The methods included matte fusion, which is used for the evaluation of resources in the field of nonferrous metal smelting, and chemical analysis using test methods outlined in Notification No. 19 of the Ministry of the Environment, provisional analytical methods for precious and rare metals in electric and electronic products (“provisional analysis method”). The content values obtained using the test methods in Notification No. 19 were lower than those obtained using the other method, but the provisional analysis method seems to be suitable for use as a screening test. Although the reproducibility of analysis using the provisional analysis method was lower than that of the matte fusion method, both methods provided comparable content values. Matte fusion is difficult to imple-ment except by the refining industry. For various and diverse metals, provisional analysis is useful by environmental laboratories operated by local governments. Therefore, the provisional analysis method is expected to be used by local governments for analyses conducted in the resource recycling field.

We devised a new pretreatment to analyze asbestos in gypsum boards that are discarded when building new structures and demolishing old ones. In this pretreatment, crushed gypsum board powder is dissolved in a water solution of ammonium formate. Then, insoluble asbestos can be separated on filter paper for XRD analysis. This pretreatment is simpler than the determination of asbestos in building material products (JIS A 1481), and XRD analysis can confirm chrysotile of 0 . 1 wt% or greater in gypsum. This method can only be applied for the analysis of gypsum, but it can be used effectively for confirming asbestos in amounts of 0 . 1 wt% or greater in the gypsum for the purpose of avoiding asbestos in it.
我们设计了一种新的预处理方法来分析在新建和拆除旧建筑时丢弃的石膏板中的石棉。在这种预处理中，粉碎的石膏板粉末溶解在甲酸铵水溶液中。然后将不溶性石棉用滤纸分离，进行XRD分析。该预处理方法比测定建筑材料制品中石棉(JIS A 1481)简单，XRD分析证实温石棉为0。1 wt%或更大的石膏。本方法仅适用于石膏的分析，但可有效地用于确定0。在石膏中添加1wt %或更大，以避免其中含有石棉。
