Effect Of Oil Spill On Hydraulic Conductivity Of Poorly Graded Sand

Pencemaran tanah oleh minyak diesel kebiasaannya berlaku disebabkan tumpahan minyak daripada kenderaan, kemalangan kebocoran daripada tangki atau kebocoran paip air. Pencemaran ini menyebabkan kerosakan yang ketara terhadap alam sekitar. Hidrokarbon yang terdapat dalam minyak berterusan memberi kesa...
