The fish samples were collected from the three different Cities of Yemeni coasts. Aden, Al-Hodeidah and AL-Mukalla were chosen for the sample collection. Lethrinusmahsena, Thunnustonggol, Sphyraenajello and Epinephelusareolatus fish samples were considered for the study as they are more common eatable fish among the population.The study was carried out in the all three seasons of winter 2011,  summer 2012 and winter 2013  in order to check seasonal variation of heavy metal pollution.Total  Fish (108 samples of each muscles, liver and gills) were analyzed. The four heavy metals lead, Cadmium, Mercury and arsenic which are considered highly toxic were detected in the samples in the year 2010, 2012 and 2013. The mean concentration of Pb, Cd, Hg and as in muscle was 0.101±0.012, 0.046±0.010, 0.058±0.002 and 0.089±0.002 µg.g-1 dry wt. respectively; whereas in liver was 0.196±0.033, 0.132±0.020, 0.102±0.007 and 0.115±0.0005 µg.g-1 dry wt. respectively; whereas in gill was 0.294±0.042, 0.196±0.063, 0.016±0.0006 and 0.034±0.0005 µg.g-1 dry wt. respectively. The  results showed that, the heavy metals concentrations were high in stations AL- Hudaydah  and AL- Mukalla and low in station of Aden. Also the heavy metals concentrations were high in Seasons summer and low in Seasons winter. From the heavy metal concentrations mentioned above we can see that somewhere the concentration is crossing the limits as permissible by the World Health Organization. It suggests a high risk to the health of human being on the consumption of contaminated fish. Therefore it is recommended that the practice of trace element detection should be continued in order to update whether the heavy metal concentration is above or below the permissible limits and if it is above the limit then precautions must be taken to avoid possible consumption of contaminated eatables.

Peer Review History:

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
