である。2. Description of the Related Art Conventionally, the lawn of a golf course is protected from pests,
Large amounts of insecticides, herbicides, and fungicides and fertilizers are used to grow. Prefectural governments provide guidance on proper use of pesticides and regulation of total amount of pesticides to prevent environmental pollution by pesticides. On the other hand, private companies sell various pesticide countermeasure products and removal systems. Among these, few of the countermeasure products can immediately remove many kinds of pesticides and can maintain the removal effect for many years. Recently, a pesticide adsorption decomposer in which an adsorbent such as activated carbon is mixed with a porous sintered body obtained by firing a metal oxide composed of silicon dioxide, calcium oxide, aluminum oxide, iron oxide, manganese oxide, magnesium oxide, and potassium oxide. Can be seen (JP-A-4-110035).
However, it is not always possible to expect a long-term removal effect for many types of pesticides. In addition, the current situation is that there is no countermeasure product for simultaneous removal of pesticides and nutrients. Furthermore, regarding the removal system, the current situation is that the introduction of the system and the maintenance and management of the system have a large economic load.

た。Experimental Example 4: Agrochemical Removal Ability (Field Experiment) A water pipe was provided at the bottom of an experimental field with a width of 2 m and a depth of 2 m, and a remover with a thickness of 5 cm was laid on top of it, which is commonly used at golf courses in the Chubu region. A mixture of mixed mackerel soil and Kiso sand was laid on the grass for 30 cm, and then a pesticide removal experiment was conducted.

Water corresponding to 0 mm was uniformly sprayed on the experimental field, and the water discharged from the water pipe was analyzed. As the remover, the porous ceramic-based remover of Example 3 of the present invention and a commercially available pesticide adsorbent were used, and the pesticide concentration in the effluent was measured. The results are shown in Table 4.
