A wat.r-swelling mat.rial is one of t.e rubbery impermeable mat.rials which mixed synt.et.c resin elast.mers as a base mat.rial, high absorbency polymers, filler and solvent.. In t.is st.dy, swelling charact.rist.cs of t.e wat.r-swelling mat.rial on t.e wat.r pollut.d wit. COD and BOD, as an impermeable mat.rial at.coast.l landfill sit.s, are examined by laborat.ry swelling rat.o t.st. Furt.ermore, t.e fact.r in which it.influences t.e swelling pressure of wat.r-swelling mat.rial is clarified by measuring t.e swelling pressure. As t.e result., t.e COD nor t.e BOD concent.at.ons in t.e soaked wat.r influence t.e swelling rat.o of t.e wat.r-swelling mat.rial. When t.e t.icknesses of wat.r-swelling mat.rial are 2 mm and 3 mm, t.e maximum swelling pressure of 0.5 MPa or more t.at.corresponds t. hydraulic pressure by dept. of 50 m is possessed.

In Houst.n, a combinat.on of urban emissions from a cit. of 4 million people, coupled wit. emissions from ext.nsive pet.oleum refining and chemical manufact.ring, leads t. condit.ons for phot.chemist.y t.at.are unique in t.e Unit.d St.t.s, and hist.rically, t.e cit. had experienced some of t.e highest.ozone concent.at.ons recorded in t.e Unit.d St.t.s. Large air qualit. field st.dies （t.e t.xas Air Qualit. St.dies or t.xAQS I and II） were conduct.d t. det.rmine root.causes of t.e high ozone concent.at.ons. Hundreds of air qualit. invest.gat.rs, from around t.e world, deployed inst.ument. on aircraft. on ships, and at.fixed ground sit.s t. make ext.nsive air qualit. measurement.; det.iled phot.chemical modeling was used t. int.rpret.and assess t.e implicat.ons of t.e measurement.. t.e t.xas Air Qualit. St.dies revealed t.at.bot. cont.nuous and episodic emissions of light.alkenes, which came t. be called highly react.ve volat.le organic compounds, played a crit.cal role in t.e format.on of ozone and ot.er phot.chemical oxidant. in t.e region. Under- st.nding and quant.fying t.e role of t.ese emissions in regional air qualit. required innovat.ons in charact.rizing emissions and in phot.chemical modeling. Reducing emissions required innovat.ve policy approaches. t.ese coupled scient.fic and policy innovat.ons are described, and t.e result. subst.nt.ally cleaner air for Houst.n, is document.d. t.e lessons learned from t.e Houst.n air qualit. experience are relevant.t. cit.es wit. similar populat.on and indust.ial profiles around t.e world.
