The City

The impact of the urban effluents of Mytilene (Lesvos island, Greece) on the receiving coastal marine environment, was evaluated by studying the quality of the city effluents (BOD5, COD, SS, heavy metals) and the marine sediments (grain size, organic matter, heavy metals). It was found that the urban effluents of Mytilene contain high organic matter and suspended particle load because of septage discharge into the sewerage network. Furthermore, although the city does not host important industrial activity, its effluents contain appreciable metal load, which is mainly associated with the particulate phase. The city effluents are discharged into the coastal marine environment and their colloidal and particulate matter after flocculation settles to the bottom, where is incorporated into the sediments. Over the years, the accumulation of organic matter and metals into the harbour mud has created a non-point pollution source in the relatively non-polluted coastal marine environment of the island. Copper and Zn were the metals which presented the higher enrichment in the sediments of the inner harbour of Mytilene.

Environmental Challenge

This article appraises the Factors deteriorating marine environment due to violation of marine pollution laws in Pakistani waters. The environmental degradation of Pakistani waters especially in Karachi coast became a serious threat to the marine environment, marine life as well as human health and marine vessels since long for society. It is determined the level and the distribution pattern of various heavy metals in the coastal waters significantly higher than the standard values. Pollution created by a number of sources is the major contributing factor in this regard. Amongst all, the deteriorating environment in Pakistani waters warrants immediate corrective actions to control Marine Pollution in order to curtail further destruction by this menace. Many steps at Governmental and private level have been initiated however, improvement is a dream. It is rightly to mention that there is no dearth of legislation on the pollution control but implementation of the same by all the concerned agencies and cooperation by public in true letter and spirit is a dream. The prevailing environment cannot be improved without effective enforcement of existing laws in its true perspective by removing all obstacles and difficulties with creating political will of society.
