“…[44] Bromophosethyl was detected in our tested samples all over 2012 at low concentrations with a high frequency of detection. In agreement with other monitoring programs, [45] the low obtained concentrations revealed that this pesticide is no longer used. It is considered as persistent contaminant because of its slow degradation process in all media.…”

This study reviews the detection of pesticides in different surface and groundwater samples collected from South Litani region in South Lebanon during 2012. These have been analyzed using an optimized and validated solid phase extraction method followed by gas chromatography coupled with mass spectrometry. Organochlorine and organophosphate pesticides were mostly noted at levels below the recommended value for individual pesticide in water except pirimiphosmethyl that was recorded at 300.87 ng L −1 in groundwater sample, designated for drinking water and collected in February. DDE concentration exceeded 100 ng L −1 in both surface and groundwater in October. The reported results represent the first Lebanese statistical data illustrating the quantification of pesticides in water over a period of time. More importantly, it draws attention to the need of pesticides' monitoring programs in the Lebanese water resources.

“…The chemical composition of the Dead Sea brains consists of several salts with the approximate (weight/weight) percentages: magnesium chloride (14.5%), sodium chloride (7.5%), calcium chloride (3.8%), potassium chloride (1.2%) and magnesium bromide 0.5% (Al Bawab et al 2017;Es-Shahat et al 2003). The average ion concentrations of the Dead Sea brine over the period of 1987 to 2008 are reported, and it is found that the major ion composition of the Dead Sea is chloride as a dominant anion and magnesium, sodium and calcium as the dominant cations (Khlaifat et al 2010).…”

The unique climatic condition of the Dead Sea area makes it a renowned site for climatotherapy worldwide. Its water and mud are used for therapy and as sources for many cosmetic products. The high evaporation rate of the water of the Dead Sea makes the measurements of its minerals' concentrations with time a necessity. Therefore, the aim of this study is to determine the metal contents in both water and mud of the Dead Sea which may have influence on human health. Major, minor and trace elements (Na,

“…Further studies evaluating impacts on gonad development following exposure to ≤ 200 µg VZ/L, would be required to establish a LOEC. Using reported values of VZ in surface waters [17][18][19], and our estimated NOEC of ≤ 200 µg VZ/L, the risk quotient (RQ, the ratio of maximum environmental concentration to predicted noeffect concentration) would suggest that VZ is of low risk (RQ < 0.1) to fish in most areas, but medium risk in areas with ≥ 20 µg VZ/L (RQ 0.1 to 1) [34]. In order to compare our findings with the predicted toxicity of VZ, we applied a QSAR model (ECOSAR, [35]).…”

“…It has been detected in surface waters at concentrations ranging from 0.1 -2.4 µg/L [18,19] and as high as 52 µg/L [17]. Vinclozolin and its metabolites, butenoic acid (M1) and enanilide (M2) act as androgen antagonists [16,20,21].…”
