Assessment of parasitic pollution in the coastal seawater of Gaza city.

Hilles AH, Al Hindi AI, Abu Safieh YA - J Environ Health Sci Eng (2014)

Bottom Line: The results show that about 48% of the seawater samples from the shoreline region of Gaza City were contaminated with parasites.The parasitic species found were: Ascaris lumbricoides, Giardia lamblia, Strongyloides stercoralis, Hymenolepis nana, Entamoeba histolytica/dispar and Cryptosporidium parvum.The present study revealed a high level of contamination with parasites at most of the points which were investigated along the Gaza City coast line.

ABSTRACT

Background: The main objective of the study was the assessment of the prevalence and the identification of species of human gastrointestinal parasites as an indicator of the pollution of the seashore of Gaza City.

Methods: The investigation was conducted by analysis of the parasitic contamination of seawater along the study area. A total of 52 samples of seawater were analyzed during the summer period; from June to October 2011. The study area was divided into six zones (A, B, C, D, E and F) according to specific criteria such as the presence of the wastewater discharge points and other geographical characteristics.

Results: The results show that about 48% of the seawater samples from the shoreline region of Gaza City were contaminated with parasites. Zones A, B and D (mouth of Wadi Gaza, Al Sheikh Ejleen discharge and Al Shalehat discharge points respectively) have the highest level of parasitic contamination, while, zones C and E (From Al-Baydar restaurant to Khalel Alwazer Mosque and the basin of the Gaza marina respectively) had a lower level of contamination and zone F (From the northern part of the Gaza marina to the Intelligence Building) was uncontaminated. The parasitic species found were: Ascaris lumbricoides, Giardia lamblia, Strongyloides stercoralis, Hymenolepis nana, Entamoeba histolytica/dispar and Cryptosporidium parvum.

Conclusions: The present study revealed a high level of contamination with parasites at most of the points which were investigated along the Gaza City coast line.

Figure 4: Mean of parasitic contamination in North and South of the discharge points.

Mentions: FigureĀ 4 shows the mean of parasitic contamination for the six samples taken from the southern side of each of the major discharge points (wastewater sources) compared with that of the other six samples taken from the northern side of those discharge points. The results show that all of the samples located in the northern side of the discharge points have a higher level of parasitic contamination than the samples from the southern side of the discharge points.
