Presentation Transcript

Purpose for attending this course
Purpose for attending this course soil, water and fertilizer

  • Gain knowledge of Risk Assessment

  • Relates to my work

  • To know more analysis methods

What i have studied
What I have studied??? soil, water and fertilizer

  • “Silent Spring” & “Our Stolen Future”

  • Endocrine Disrupting Chemicals

    • Naturally or Synthesis substances

    • Effect to human

    • Can change sex in some species

    • Concentrate through the food chain

  • Food Safety soil, water and fertilizer

    • Calculate by Acceptable Daily Intake value (ADI)

    • Study of toxicity of each substances

    • Pesticide safety evaluation committee

    • Endocrine Disruptor suspected pesticide

  • Maximum Residue Limit (MRLs) soil, water and fertilizer

    • Related to the ADI value

    • Set up for each pesticides

  • Good Agricultural Practice (GAP)

    • Decrease the effect of pesticide

    • Reduce the dosage volume

    • More effective control

  • Safety assessment of pesticide

  • How to conserve the environment…

Dioxins pcbs cfc
Dioxins, PCBs, CFC soil, water and fertilizer

  • Remain in the environment for a long time

  • Accumulated in the body of living creature

  • Concentrate through the food chain

  • How to conserve and sustain the environment

Registration of new pesticides
Registration of new pesticides soil, water and fertilizer

  • Eco-toxicological effect study

  • Environment fate study

  • Ecological risk assessment toxicity exposure ratio

  • Study of distribution, effect and fate of man-made organic substances

  • Bio accumulation in the environment soil, water and fertilizer

    • Accumulation of Organochlorines in river water and sea water

    • Accumulation of Organochlorines in stripped dolphin

    • Accumulation of Organochlorines in plankton in Osaka bay area

Treatment of agro chemical compounds
Treatment of agro-chemical compounds soil, water and fertilizer

  • Degradation of Organophosphorus by bacteria

  • Isolation of TCP degrading bacteria from river water and properties of bacteria

  • Degradation of TBT by the bacteria in the river water, sea water and isolation of TBT degrading bacteria from the river water.

Solid waste management
Solid waste management soil, water and fertilizer


  • Reduce mass

  • Deodorization

  • Detoxification

    Exhaust treatment is require for eliminate particulate matter such as HCl, SO2, NO2, dioxins and heavy metals

Alternative way to reduce dioxins
Alternative way to reduce dioxins soil, water and fertilizer

  • Control the temperature to above 850C

  • Activated carbon

  • Active coke reactor

  • Dioxin catalyst

Consideration of waste management policy
Consideration of waste management policy soil, water and fertilizer

  • Current status of waste treatment/disposal

  • Responsibility of waste

  • Treatment and disposal technique for hazardous waste

  • Source of emission

Metabolism of pesticide in plant study
Metabolism of pesticide in plant study soil, water and fertilizer

  • Extrapolate toxicity effect in human from animals study

  • in vivo study use labeled compound and inject into animal

  • Pesticide and metabolite have different toxicity properties

  • in vitro study is for the metabolism study such as a cell culture

Soil study
Soil Study soil, water and fertilizer

  • Prediction half-life of pesticide

  • Clay type hold more pesticide than sandy soil

  • Leaching test; the herbicide was contained in mineral soil than volcanic ash soil

  • NO3 caused a meehemoglobinemia disease

Practice observation
Practice/Observation soil, water and fertilizer

  • GC, GC-MS

  • LC, LC-MS

  • UV-Vis spectophotometer

  • Portable devices such as pH, DO, CO, CO2, conductivity

  • AAS

  • Water quality assessment in agriculture

  • Study of effect of pesticide on soil microbial biomass

  • Pesticide residue analysis

  • Rapid analysis

Kobe quarantine station
KOBE Quarantine Station and Fisheries (HPTCAFF)

  • Simultaneous analysis of pesticide residue in fruits and vegetables

  • Simultaneous analysis of pesticide residue in Cereals, Beans and Seeds

  • GC-MS for screening and fast analysis

  • Principle of Good Laboratory Practice (GLP)

  • Confirm the result with GC
