The phosphonate fertilizers, Calphos （calcium phosphonate）, Magphos （magnesium phosphouate） and Phosphoros （potassium phosphonate） were used in Jordan and showed a nematicidal effect. This study aimed to investigate the fungicidal effect of these fertilizers against the growth of the fungi, Fusarium proliferatum, Altrenaria solani, Pythium debaryanum and Penicillium digitatum. Results showed that the phosphonate fertilizer Calphos at the concentration of 1% mixed with potato dextrose agar （PDA） totally inhibited the growth of all studied fungi. Magphos （1%） delayed the growth of the fungus F. proliferatum and inhibited the growth of other tested fungi. While Phosphoros （1%） mixed with PDA inhibited the growth ofA. solani and P. digitatum even after 12 d of incubation and delayed the growth ofF. proliferatum and P. debaryanum compared with the growth of the fungi on the PDA only.

The widespread mobile station’s antennas and the continued increase in the number of mobile phones users throughout the Gaza strip causing great panic in the population relating the debate overexposure to electromagnetic radiation EMR emitted from the antennas of mobile base stations. Therefore, this study was conducted to measure the levels of electromagnetic radiation emitted from the antennas of cellular base stations in Gaza governorate as well as to evaluate the citizen’s awareness and practices regarding potential health risks and mitigation methods of exposure to electromagnetic radiation emitted from cellular base stations, respectively. Fifty cellular base stations out of 197 stations were selected depending on the criteria of selecting one site per kilometer using Global Positioning System (GPS). Electromagnetic power density, electric field strength, and the magnetic field strength emitted from cellular base stations were measured using Narda-550. Assessment tool for observation was used to collect operational information of each station. A structured questionnaire with four-level Likert rating scale was used to survey 384 mobile phone users from the areas surrounding the selected cellular base stations. The results showed that the electromagnetic radiation levels of all stations were low and less than the national and international acceptable limits. Furthermore, the awareness of participant about health risks that could result from exposure to electromagnetic radiation emitted from cellular base stations and mobile phones was low. Nevertheless, the participant’s practices in mitigating the adverse impacts of electromagnetic radiation emitted from cellular base stations and mobile phones on their health were good.

Background: Worldwide, breast cancer (BC) is the most frequently diagnosed neoplastic disease in women around menopause that is the leading cause of DALYs, because it causes a significant reduction of these women’s ability to function normally in everyday life. Methods: The present hospital-based case-control study was carried out between January and August 2018 using a structured questionnaire on 105 breast cancer women and 210 controls who are clinically free from breast cancer. Data about the study cases were collected in the oncology day-care clinics of the two main hospitals in Gaza strip “Al-Shifa and European Gaza hospitals”. Univariate logistic regression and multivariate logistic regression analyses were employed to identify the significant factors associated with BC. Results: Multivariate logistic regression analyses with adjustment for all confounders revealed that woman with BMI more than or equal 30 kg/m2 are under risk of getting BC 2.9 times greater than those having BMI less than 29 kg/m2 (AOR = 2.895;95% CI: 1.305 - 6.423). Analysis of risk according to reaching menopause showed that the estimated AOR was greater among those reached menopause (3.137, 95% CI 1.824 - 5.395) than among those that did not reach menopause. The risk of developing BC in the case of a history of incidence of BC in the family was more than two times higher (AOR = 2.632, 95% CI 1.528 - 4.535) than in case of the history of a free family of BC. Conclusion: In this context, the above-mentioned risk factors must be taken into consideration in BC management processes in the Gaza strip.

Water quality and occurrence of water-borne diseases in the Gaza strip are vivid examples for most developing societies. In recent years, the quality and quantity of groundwater, the only source of waters in the Gaza strip, have deteriorated markedly. A general rundown of the infrastructure and water distribution networks, in particular, the spread of cesspools, excessive use of pesticides and fertilizers, and improper treatment and disposal of wastewater remain major contributing factors to the continued deterioration in the water status in the Gaza strip. Without a doubt, the (Israeli)-Palestinian conflict had a clear negative impact on the water sector in the Gaza strip. Apparently, there is a dire need to adopt the WHO’s water safety plan in the management of Gaza’s water supply systems from catchment to consumer’s tap in order to maintain the sustainability and quality of water resources and prevent outbreaks of waterborne diseases. Therefore, this review has been prepared to highlight the overall picture of the water dilemma in the Gaza strip in the last years and in addition, to identify the sources, sorts, levels, and health risks of consequence to microbial contamination of water. The impact of political conflicts on the water sector in the Gaza strip also was reviewed. Furthermore, recommendations were formulated in order to assist and guide future researchers, stakeholders, and policymakers to avoid the more exacerbation of water contamination as well as to protect public health.
