Konpoze polikik arom ki pi wo a twa bag gen solubility ba ak presyon vapè ki ba nan dlo. Lè ogmante nan pwa molekilè, tou de solubility ak presyon vapè diminye. Bicyclic polycyclic composés konpoze yo gen pi ba solubility ak presyon vapè. Konpoze polikik aromik yo se poutèt sa pi souvan yo te jwenn nan tè a ak nan sediman pase nan dlo ak lè. Sepandan, konpoze aromatik arik souvan yo jwenn sou sispansyon patikil nan lè a.

Polycyclic aromatic compounds above three rings have low solubility and low vapor pressure in water . When the molecular weight increases, both solubility and vapor pressure decrease. The bicyclic polycyclic aromatic compounds have lower solubility and vapor pressure. Polycyclic aromatic compounds are therefore more commonly found in the soil and in sediments than in water and air. However, polycyclic aromatic compounds are often found on suspended particles in the air.
