“…Most research had concentrated on the use of date stones instead of powders as potential adsorbents. Some workers, 29 who fed different doses of date palm seed on some species of fresh water fish recorded a significant decrease on the heavy metal concentrations of the fishes. They therefore concluded that feeding common carp a diet enriched with date palm seed extract could decrease heavy metal concentration that can cause cancer.…”

At the present time, there is continuous increase of heavy metal burden in our environment, which has become one of the most serious problems globally. Heavy metals cause threat on land and in aquatic life. The problem of metals is significantly attributed by increase of activities from industrial, agricultural, hospital sectors etc. Heavy metals are not degradable, but they are persistent in environments. The aim of this study is to prepare adsorbent from powder of Ajwaa date seeds (PADS). The adsorbent was applied in removing heavy metal ion such as cadmium, lead, copper, chromium, cobalt and manganese from aqueous solution. The study also examined the removal efficiency of PADS. Constant mass of 0.1gram of PADS which was added in a volume of 50 mL of ultra-pure water reached maximum removal efficiency of 93.34%, 71.06%, 92.06%, 96.96%, 95.91% and 36.13% for Cd 2+ ions, Cr 3+ ions, Co 2+ ions, Cu 2+ ions, Pb 2+ ions and Mn 2+ ions respectively. The findings of the present study can be taken as a best solution and baseline information of heavy metal removal in different areas. The PADS treatment is efficient, simple, low cost and green alternative for heavy metal treatments methods to overcome the problems of heavy metals discharged in aqueous solution.

The current work presented here focuses on the remediation of mercury from water using modified low-cost materials. Modified date pits, low cost, minimal pretreatment steps and locally abundant agricultural waste materials were effectively employed as an adsorbent for remediating Hg2+ from aqueous media. Physical and chemical modification were developed such as thermal roasting (RDP), sulfur (SMRDP) and silane (SIMRDP) based modifications. Results showed that maximum adsorption by RDP was at pH 6, AC and both modifications was at pH 4. Furthermore, RDP has exothermic adsorption mechanism while AC, SMRDP, and SIMRDP have endothermic. All adsorbents except SIMRDP have spontaneous adsorption process. SEM analysis showed that the surface morphology of RDP was not significantly affected by different treatments while surface of AC was affected. The investigation for good adsorbents for Hg2+ uptake from different anthropogenic sources has been carried out by many investigators worldwide towards having a safe environment. In the current study, the highest Hg2+ adsorption of SMRDP was relatively high compared to other known adsorbents.

“…Date palm seeds are rich in fibers and phenolic compounds which mask the deteriorating effects of mercury. This useful function was recently pointed to in carp fish exposed to mercury and lead [ 47 ]. The supplementation of carp diet with date palm seeds at 1–4% of the diet significantly reduced muscle and liver content of mercury compared to positive control.…”

ObjectiveHeavy metals are major elements polluting our universe. The inhalation, ingestion or even contacting human body with these elements results in huge health problems. The most common pollutant in our surrounding is mercury. Therefore, the present study aimed to elucidating the protective ability of hot water extracts of dandelion (DA), coriander (CO), date palm seeds (DS), probiotic supernatant (PS) and their combined mixture against mercury-induced neurotoxicity and altered testosterone levels in male rats.MethodsFifty six male rats were randomly allotted into seven groups (n = 8 rats/group). Group1 (negative control; NC) animals were fed on the basal diet only, group2 (positive controls; PC) animals were fed on the basal diet and given an aqueous solution of mercuric chloride (25 ppm mercuric) in drinking water. Animals of the antioxidant-treated groups (3–7) were fed on the basal diet and given an aqueous solution of mercuric chloride (25 ppm mercuric) in drinking water together with the herbal antioxidant extracts and probiotics (25 ml/rat/day) throughout the experimental period. Where, group3 (Hg/CO) given coriander extract, group4 (Hg/DA) given dandelion extract, group5 (Hg/DS) given date palm seeds extract, group6 (Hg/PS) given probiotic supernatant, and group7 (Hg/Mix) given mixture of equal quantities of probiotic supernatant together with the three herbal extracts. The treatment lasted for 6 weeks, animals were sacrificed and blood samples were collected. Blood testosterone, enzyme activity and histopathological sections were performed.ResultsThe obtained data exhibited that mercury intoxication revealed increases of lactic dehydrogenase and decreases of glutathione-s-transferase and testosterone. Light microscopic investigations of the brain cortex and cerebellum were suggestive of multiple foci of inflammation, cellular infiltration, gliosis and degeneration. Moreover, decreased glial fibrillary acidic protein (GFAP)-immunoreactivity and potential astrocyte toxicity both reflected impaired neuro-protective function of astrocytes necessary for maintaining the brain structure and function.ConclusionAdministration of the herbal extracts and their mixture with probiotics enhance the body defense and contain protective factor against mercury neurotoxicity and for maintaining normal testosterone levels in male rats. Also, treatment restored the normal control levels of biochemical attributes and histological architecture.
