“…Despite the mortality of eggs and larvae that could occur after a spill, there is rarely a subsequent decrease in natural adult population. This can be explained in part by the considerable natural recovery of marine ecosystems to various high-gravity impacts.Marine organisms adapt rapidly to naturally high mortality levels, among other reasons by producing large surpluses of eggs, larvae andincorporation of populations reserves outside the affected area 13 Naphthalene can be identified as a modestly volatile compound, which allows its concentration to decrease more easily in the environment versus other compounds of the same group.This characteristic is related to its low molecular weight (MW) which in turn allows it to be available to organisms facilitating their mobility with respect to other PAHS and being retained for short periods of time 14 . Nonetheless, the compound with the highest concentration in the present study was naphthalene, corresponding with that reported by Pozo K. et al (2011) 15 , in that naphthalene, the simplest of the low molecular weight PAHs, was found at relatively elevated levels, which suggests that its source was mainly anthropogenic 16 .…”

Samples of fish species Lutjanus synagris (lane snapper, pargo biajaiba or pargo rayado) and Centropomus undecimalis (Common snook, sergeant fish or robolo) from municipality of Covenas and corregimiento of Berruga in the Gulf of the Morrosquillo (Department of Sucre, northern Colombia), were collected to evalute therir pollution degree with polinuclear aromatic Hydrocarbons (PAHs), also called Polycyclic Aromatic Hydrocarbons. Analysis to detect residual concentrations of siteen posible PAHs in fish muscles were carried out with gas chromatography coupled by masses (GC/MS). Results showed 11,230 µg.kg-1 of PAH saverage total concentrations for Lutjanus Synagris (ranging from 0,004 to 145,596 µg.kg-1) and 8,596 µg.kg-1 for Centropomus undecimalis (ranging from 0,002 to 85,915 µg.kg-1) where PAHs classified as carcinogenic (venzo[a] pyrene, dibenzo [a, h] anthracene), showed a low frequency in the detection. This condition allows to consider that PAHsaverage values do not represent an immediate risk for human health, but it would be a potential one because of the bio-accumulation property of these pollutants. Thus, a continuous monitoring of this problema is recommended since it could become a risk for the environment and public health.

Petrogenic hydrocarbon spills (PHS) are harmful to mangrove ecosystems along tropical coastlines both in the short and long term. The aim of this study was to assess the environmental risk of recurrent PHS on mangrove ecosystems in Tumaco municipality, Colombian Paci c. Mangrove characteristics and management aspects led to subdividing the entire the study into 11 units-of-analysis (UA) for which threats, vulnerability, potential impacts, and risks were assessed based on environmental factors and the formulation and use of indicators in a rating scale with ve categories, which are very low, low, moderate, high, and very high. The results showed that all UAs are highly (64%) or moderately (36%) threatened by PHS, highly (45%) or moderately (55%) vulnerable to this kind of pollution, and susceptible of high (73%) or moderate (27%) potential impacts. Environmental risk was high in 73% of the UAs, indicating likely irreversible damage to mangrove ecosystems by PHS, thus pointing to the need of urgent intervention by responsible authorities to ease their recovery and conservation. The methodology and results of this study become technical inputs that serve for environmental control and monitoring, which can be incorporated into contingency and risk management plans.
