The main pigments found in oil palm tree leaf are chlorophylls a, b, and c. Chlorophyll a converts light energy into chemical energy through photosynthesis process. The content of chlorophyll pigments varies by their ages. The aim of this research was to determine the concentration in chlorophyll a in different ages. This study is significant in oil palm fertilization for monitoring oil palm nutrient content (NPK). Chlorophyll measurement was done by extracting using methanol solvent and concentration measurement using spectrophotometric method in order to quantify chlorophyll a concentration based on their ages. 6 samples of oil palm tree leaves, collected from 2 different ages, were analyzed. The observed values were determined based on the absorbance at wavelength (670nm) and were calculated for concentrations value based on to the Lambert-Beer law Equation. It showed that the chlorophyll a concentrations at the age of mature stage had been higher than those at the old stage. The results depicted that the chlorophyll a concentration values at the mature stage were 0.33mg/ml, 0.32mg/ml, and 0.18mg/ml, while at the old stage were 0.22 mg/ml, 0.18mg/ml, and 0.06mg/ml.

This paper was studying the effects of palm tree wastes on the behavior of the concrete to reduce cement content in the concrete to ensure a sustainable environment. Both fibers of palm tree and the ash of palm tree leaves are used in this study considering different percentages of palm tree wastes, which are replaced the cement, to investigate both of workability and strength of the concrete. Also, the combination of palm tree leaves ash and fibers of palm trees is investigated. The slump and compression tests are carried out to evaluate both workability and concrete strength. The palm fibers were reducing the workability of concrete at both of different percentage of replacement and different fiber lengths. The slump is reduced by 26.667% at 2 cm fibers length and it is completely lost at 5 cm length fibers at the same percentage of replacement of 5% of the cement content. The palm fibers were weakening concrete compressive strength at different percentages and different fiber lengths. Palm leaves ash was enhancing concrete workability and concrete compressive strength.

Purpose Industrialization is leading to gradual accumulation of heavy metals in the date palm fruits and ecosystem. This paper aims at estimating the bioaccumulation of  heavy metals in soils, fruits (dates) near the industrial area of Al-Rusail in the Sultanate of Oman. There were three sites located for sampling and each with three farms except site 3 with one farm; industrial site, cement factory and control farm. The soil, water and date palm fruits were analyzed for heavy metals concentration using inductively coupled plasma optical emission spectrometer. The results of  analysis showed that the mean concentration of heavy metals in soil was in the following order: Ni> Zn > Pb > Cd. The concentration of heavy metals in the groundwater was found to be in this order Zn > Ni> Pb> Cd, and Zn> Pb > Ni > Cd in fruits. The statistical interaction of heavy metal mean concentrations indicated cadmium with the highest mean (0.007117mg/kg) in Farm 1 during the month of June at 0-30cm (mg/kg) in soil under Industrial sites. The fruit stages differ statistically with the highest concentration of zinc ranging from 0.190517 mg/Kg of khalal stage of farm 1 to the 0.03127 mg/kg of the control farm. groundwater heavy metal concentration was very low across the farms with the least (Cd at 0.0002434mg/Kg) in control site and not statistically different from other sites' farms.In general, the research indicated an increases in the heavy metal concentrations with closeness to industrial sites.
