The high N[O.sub.2.sup.-]-N concentrations at station 2 ([approximately equal to] 0.081 mg/L of N[O.sub.2]) and station 3 ([approximately equal to] 0.065 mg/L of N[O.sub.2]) exceeded the MWQS (0.055 mg/L of N[O.sub.2]) in Malaysia (Table 1).
IP content at station 2, N[H.sub.4.sup.+]-N content at station 3, and N[O.sub.2.sup.-]-N content at the two stations also exceeded the guideline value of the MWQS. Station 1 was the only station along the coastline where Chl-a status was categorized as eutrophic status.
Coastal water quality at other stations was relatively good and mostly complied with the MWQS, except for N[O.sub.3.sup.-]-N where all stations violated the MWQS.
Results showed that N[O.sub.3.sup.-]-N concentration exceeded the MWQS in the coastal waters.
