  1. 1. Research Progress on Biodegradation of Environmental Estrogen: 4-t-octylphenol in Sewage Sludge Liu Yang from Environmental Science
  2. 2. Contents What’s 4-t-octylphenol Harmful effects of 4-t-octylphenol Why choose 4-t-octylphenol What the experimental plan
  3. 3. What’s 4-t-octylphenol 4-t-OP for short non-ionic surfactant family components of plastics, detergents, paints, pesticides, emulsifiers, wetting agents, solubilizers and dispersants
  4. 4. Where the strains being screened from
  5. 5. Harmful effects Reproductive Disorder Inhalation : Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of breath. Ingestion : Causes irritation to the gastrointestinal tract. Symptoms may include nausea, vomiting and diarrhea. Aspiration into the lungs may occur during swallowing or vomiting, resulting in lung damage.
  6. 6. Skin Contact : Brief contact may have no effect . Prolonged or repeated contact may cause irritation, redness, itching and pain. Eye Contact : Can cause severe eye irritation with symptoms of inflammation, tearing, blinking, redness, swelling of the conjunctiva, and chemical burns of the cornea.
  7. 7. Why choose 4-t-OP Environmental estrogen 27 PTSs Measurable Less references
  8. 8. Experimental Plan Select the sampling points Screen ing Further study: biodegradation effects, controls of different living condition, degradation products of the strains and the compound
  9. 9. Thank you all!
